BMC Performance Manager Express for EMC Disk Arrays

Version 2001

BMC Performance Manager Express for EMC Disk Arrays is an agent-less Performance Manager forthe BMC Portal environment It allows you to automatically discover and monitor every aspect of EMCdisk arrays from the general health of the array to the performance of the LUNs and from the filesystems space usage to the mirroring and snapshots mechanisms latency and to consolidate diversemonitoring needs within the Portal framework through a single solution

To setup a complete monitoring of the disk array we strongly recommend you to also use BMCPerformance Manager Express for Hardware that covers all the physical aspect of the disk array (statusof the disks ports temperature power supplies power consumption etc)

Being a Performance Manager specifically designed for BMC Portal BMC Performance ManagerExpress for EMC Disk Arrays uses the Portalrsquos web-based interface and features for installingmanaging and monitoring your infrastructure

Getting Started

11

BMC Performance Manager Express for EMC Disk Arrays

Version 2001

This chapter describes the prerequisites and the procedures you must perform before installing BMCPerformance Manager Express for EMC Disk Arrays Please follow the given instructions carefully inorder to ensure a successful integration of the solution within the Portal environment

Minimum Requirements

The computer on which you install BMC Performance Manager Express for EMC Disk Arrays shouldalready have

1 BMC Performance Manager Portal version 2500

2 Access to an RSM ie Remote Service Monitor

The RSM program must be installed on a Windows platform This can either be same as the serverwhere the Portal is installed or any other Windows computer on the network

Once you install BMC Performance Manager Express for EMC Disk Arrays you can add as manyelements as you require in your monitoring environment

Enabling the statistics

On EMC Clariion and VNX storage systems the statistics need to be enabled to allow BMCPerformance Manager Express for EMC Disk Arrays to collect statistics and to monitor performance

Using Navisphere

1 In Navisphere enable Statistics logging

middot Open Navisphere

middot Right-click the icon for the storage system

middot Click Properties

middot Be sure SP A and SP B are in the Storage Processors section

middot Click the box for Statistics Logging under the Configuration section

2 For locally attached CLARiiONs check if authorization info is present

3 Run the dv command from EMC TestSMIProvider Make sure all arrays are discovered withoutany errors

4 Make sure performance is turned on in the Profile for storage arrays

5 Make sure there are instances for the CIM_BlockStorageStatisticalData class

middot Run Tek-Tools testProvider or EMCrsquos testSMIProvider

middot Type ein for command

middot Type CIM_BlockStorageStatisticalData for Class Name

middot If no instances are returned reset EMC Provider

6 Once complete resume steps 1-3

If you are using a version older than SMIKit 642 the EMC SMI-S Provider does not recognize changes in the arraywhen a LUN or RAID Group is created or deleted from Navisphere It is thus recommended to upgrade your EMC SMI-SProvider to version 642 or higher to benefit from the auto-synchronization mechanism set by default to one hour afterthe last update If you do not upgrade your EMC SMI-S Provider you will have to run the refsys command fromtestsmiprovider each time you create or delete LUN or RAID groups from Navisphere

Managing Baselines and KeyPerformance IndicatorsIn order to facilitate the detection of abnormalities on your monitored environment BMCProactiveNet calculates baselines per parameter (metrics or attributes) based on values collectedover a specified period of time to determine a normal operating range When the collected values forthese parameters are out of range an alert is triggered

Some parameters are identified by default as Key Performance Indicators and therefore automaticallyincluded in the base lining calculation

42Managing Baselines and Key PerformanceIndicators

BMC Performance Manager Express for EMC Disk Arrays

Version 2001

Managing baselines

The baseline is the expected normal operating range for a metric or attribute of a monitor

The baseline is calculated by collecting the values for a monitorrsquos attributes and metrics over aspecified time period and establishing a low baseline value (consisting of the 10th percentile of all thevalues for a given time period) and a high baseline value (consisting of the 90th percentile of all thevalues for a given time period) taking a weighted average of these values over time A higher weightis given to the latest data being factored into the baseline average The accuracy of the baselineimproves over time

Requirements for baseline generation

For baselines to be generated for an attribute that abnormality threshold means that the thresholdexists and is not suppressed Additionally if the Key Performance Indicator (KPI) mode is active only those attributes that have anactive abnormality threshold and are also KPI attributes will have baselines generated for them

Absolute thresholds (with outside baseline) or signature thresholds do not satisfy these requirements

Managing Key Performance Indicators

The KPI attribute of a parameter can be activated or deactivated manually through the BMCProactiveNet Administration Console In this PM some parameters or attributes have beendesignated as important indicators of performance (KPIs) We do not recommend that these defaultsettings are modified

However advanced users may activate or deactivate KPIs from the BMC ProactiveNet AdministrationConsole

To add or remove Key Performance Indicator (KPI) attributes for amonitor type

1 In the Administration Console from the menu bar choose Tools gt KPI AdministrationThe KPI Administration dialog box is displayed

2 From the Monitor Type list choose the monitor type for which you want to add or remove KPIattributes A list of attributes for the selected monitor type is displayed

3 In the KPI column for the attributes that you want to add or remove as Key PerformanceIndicators

middot select the KPI check box to add the corresponding attribute as a KPI

middot deselect the KPI check box to remove the corresponding attribute from the KPIs for thatmonitor type

For complete and detailed information on this procedure please refer to the BMC ProactiveNet documentation availablefrom BMC Web site

BMC Performance Manager Express for EMC Disk Arrays

Version 2001

BMC Performance Manager Express for EMC Disk Arrays monitors all of the performance metrics andusage statistics of your EMC disk arrays such as file disk space usage storage controller utilizationIOs on the diskscontrollersvolumes etc It continuously monitors the activity of each array and isalso able to build reports on past utilization statistics

To setup a complete monitoring of the array we strongly recommend you to also use BMCPerformance Manager Express for Hardware that covers all the physical aspect of the EMC diskarrays (status of the disks ports temperature power supplies power consumption etc)

This chapter explains how to use each monitoring tool ie a separate application class within theBMC Performance Manager Express for EMC Disk Arrays by Sentry Software solution

BMC Performance Manager Express for EMC Disk Arrays is a Performance Manager specifically designedfor BMC Portal consequently it uses the same common features and procedures of BMCreg Portal Thisdocument assumes that the user knows how to use the Portal and therefore explains procedures onlyrelated to BMC Performance Manager Express for EMC Disk Arrays and not on how to add ElementsElement Profiles etc Please refer to the BMC Portal documentation for details on how to use the Portal

Checking Available Spare Disks

To avoid any loss of critical data it is essential for a disk array to always maintain a pool of sparedisks that can replace the faulty disk when a disk failure occurs A disk array without any left sparedisk will not be able to keep the level of data safety and performance in case of a disk failure

The Spare Disk Count parameter of the SEN_EMC_ARRAY class reports the number of spare disksavailable for each disk array monitored with the solution By default a warning is triggered when nospare disk is available (Spare Disk Count is set to zero)

Verifying the Number of Available Spare Disks in Your EMC Disk Arrays

49Checking Available Spare Disks

BMC Performance Manager Express for EMC Disk Arrays

Version 2001

1 Select an element group in the tree view (the main Infrastructure group for example)

2 Click the Reports tab Create a report for the last 24 hours bottom 50 values of the Array|Spare Disk Count parameter of the EMC Disk Arrays application class for the BMC PerformanceManager Express for EMC Disk Arrays by Sentry Software solution

Report ndash Available Spare Disks

Detecting OversubscriptionSituations (Thin Provisioning)We call an oversubscription situation when

1 The storage pool is configured for thin provisioning (ldquothin storage poolrdquo)

2 The storage pool is oversubscribed ie the total disk space visible to the hosts (subscribers) isgreater than its actual capacity (this situation is normal for a thin pool since it is its very purpose)

3 The storage pool actual consumed capacity is nearing 100

Such situation is highly critical because the inability to allocate additional space to a LUN whenrequested by the subscriber host will lead to catastrophic data loss and corruption

When the conditions described above are met the solution sets the Oversubscription Situationparameter to 1 automatically raising a warning By default the warning for OversubscriptionSituation is issued when the Consumed Capacity Percentage parameter goes above 100 Thisthreshold can be configured in the input properties of the solution

50Detecting Oversubscription Situations (ThinProvisioning)

BMC Performance Manager Express for EMC Disk Arrays

Version 2001

Configuring Oversubscription Threshold

1 Click the EMC Disk Arrays icon and then the Configure tab

2 Edit the Oversubscription Situation Threshold () property to the appropriate value Whenthe Oversubscription Situation parameter triggers a warning it is highly recommended thatthe SAN administrators add capacity to the storage pool as soon as possible

Diagnosing Slow LUNs

If a system administrator complains that his servers are experiencing slow IOs performance and thatit is caused by the SAN you may want to verify the actual response time of the LUNs the server isrelying on

The Response Time parameter of the SEN_EMC_VOLUME class represents the average time it tookto complete the read and write operations on the LUN during the collection interval Typically theaverage response time is below 10 milliseconds You may also want to compare this value to theresponse time of the other LUNs to see whether one server is really getting worse IO performancethan another

Volume - Response Time Parameter

If the response time is low you will need to check the amount of data that is written and read onthis LUN The bad performance may simply be due to an abnormally large amount of data to processOtherwise the problem is maybe between the disk array and the server in the fiber links

51Enabling the Debug Mode

BMC Performance Manager Express for EMC Disk Arrays

Version 2001

Enabling the Debug Mode

By default BMC Performance Manager Express for EMC Disk Arrays sends only the most criticalinformation warning and error messages to the Application Collection Status parameter Mostoften this information is accurate enough to ensure that BMC Performance Manager Express for EMCDisk Arrays is functioning properly If you encounter an issue and wish to report it to customersupport you will be asked to enable the Debug Mode and provide the debug output to the supportteam

1 In the Configure tab gt under Tasks click Elements

2 Select the Element whose debug output you require and click Edit

3 Scroll down to Application Classes gt click the Application class for which you want toenable the debug mode gt click Edit

4 Select Yes from the drop-down Debug Mode list gt SaveBy default BMC Performance Manager Express for EMC Disk Arrays sends its debug output to RSM_HOMERSM(xx)serverrsmlogsen_debuglog

5 Wait for 15 minutes and then disable the debug mode by selecting No

6 Send the debug file to the support team

Pay attention to the file size -the debug output of BMC Performance Manager Express for EMC Disk Arrays could bevery large if enabled for several days

Identifying the Hosts that canAccess a LUNIn most SAN configurations each LUN belongs to a storage group whose host members are the onlyones authorized to access the LUN This is called LUN masking For each LUN the solution displaysits WWN the storage group to which it belongs to as well as the hosts member of this group Inmost cases identifying the storage group of a LUN is sufficient to recognize the server that is usingit

52Identifying LUNs not Owned by their Normal(Default) Storage Processor

BMC Performance Manager Express for EMC Disk Arrays

Version 2001

Identifying LUNs not Owned bytheir Normal (Default) StorageProcessorThe Owning Storage Processor parameter reports the name of the controller that handles IOsfor each LUN If a LUN is not currently handled by its normal (default) storage processors the nameof the default controller will be indicated as SP_B (default SP_A)rdquo

To identify LUNs that are not owned by their normal storage processor you simply need to list the Volume objects where the Owning Storage Processor parameter contains the string Default

Identifying Most Busy LUNs

To identify the LUNs that generate the most traffic on the disk array use the Read Byte Rate andWrite Byte Rate parameters of the LUN class that expose the data throughput for each LUN Usethese parameters to report on the total data traffic (per hour or per day) on each LUN in GB

To make sure that traffic is displayed cumulatively per hour select a time window of at least 12 hours in the graphwindow select at least 7 days to visualize per day cumulative data

1 In the Status tab click the Volume for which you need to check the LUNs activity then expandthe LUNs object to display the ReadWrite Byte Rate parameters

53Identifying Most Busy LUNs

Version 2001

View ing a LUNs ReadW rite Byte Rate as a graph

Identifying a Storage Processor(Controllers) OverloadTo visualize the activity of a controller in an EMC disk array use the Processor Utilizationparameter of the SEN_EMC_CONTROLLER class A warning is issued when the processor utilizationgoes too high which means that the controllers cannot keep up with the load on the disk array It isthen important to identify what is overloading the controllers

The Response Time parameter of the SEN_EMC_CONTROLLER class represents the average time ittook the controller to process the read and write requests of the hosts The higher the ResponseTime goes the slower IOs the servers will get By default the solution triggers a warning when thecontroller takes more than 10 milliseconds on average to complete the IO requests and an alarmwhen the response time reaches 100 milliseconds

Monitoring the Efficiency of theCaching MechanismEach controller in an EMC disk array can be configured to use a specified amount of memory tocache the read andor write operations The solution reports the amount of memory configured byeach controller for the read and write operations

The Write Flush Byte Rate represents the rate in MBsec at which data is committed to the disk(ie physically written) This value is to be compared with the Write Byte Rate of the disk array

55Monitoring the Efficiency of the CachingMechanism

BMC Performance Manager Express for EMC Disk Arrays

Version 2001

Comparing W rite Flush Byte Rate w ith W rite Byte Rate

The Cache Dirty Pages Percentage parameter represents the amount in percentage of the writecache that has been modified by host write operations and not yet flushed to the disks Reaching100 means that write case is too small and cannot handle the flow of write operations

Checking the Cache Dirty Pages Percentage

Reclaiming Space of Unmapped(Unused) LUNsOver time as servers connected to a SAN get decommissioned administrators find an increasingnumber of unmapped LUNs or volumes that are no longer used by any server These LUNs whileunused still occupy disk space in the disk array Being able to identify such unmapped LUNs andreclaim the disk space uselessly consumed by these LUNs will help administrators avoid unnecessaryupgrades and extensions of their disk arrays

56Reporting a Disk Space Consumption

BMC Performance Manager Express for EMC Disk Arrays

Version 2001

Reporting a Disk SpaceConsumptionMaking sure that a disk array has enough remaining disk space available is critical for severalreasons

middot SAN administrators want to make sure to be able to provision disk space for new servers whenrequested as quickly as possible

middot The disk array itself may need additional disk space for specific features to work properly likeautomatic snapshots mirroring etc

middot If thin provisioning is used the remaining disk space becomes dramatically critical since theinability to allocate additional space to a LUN when requested by the subscriber host will lead tocatastrophic data loss and corruption

The disk space used is permanently monitored for each storage pool The Subscribed Capacityparameter of the Pool class represents the amount of disk space that has been made available tothe subscriber hosts or in other words the amount of disk space that is seen by the serversconnected to disk array

The Consumed Capacity parameter of the SEN_EMC_STORAGEPOOLS class represents the actualspace usage in the storage pool For thin pools (when thin provisioning is enabled on the disk array)this value is normally lower than the Subscribed Capacity as it is the main purpose of thinprovisioning For traditional pools the Consumed Capacity parameters has the same value as theSubscribed Capacity parameter as the entirety of the subscribed disk space is fully allocated inthe storage pool

The Consumed Capacity Percentage parameter is the most critical one as a storage pool usagenearing 100 means that SAN administrators will not be able to create new LUNs in the storagepool By default no alarm or warning threshold is set on this parameter as the fullness of a storagepool may be a normal situation However you can set alert thresholds on this parameter as it fitsyour needs

57Reporting a Disk Space Consumption

BMC Performance Manager Express for EMC Disk Arrays

Version 2001

BMC Performance Manager Express for EMC Disk Arrays is an agent-less Performance Manager forthe BMC Portal environment It allows you to automatically discover and monitor every aspect of EMCdisk arrays from the general health of the array to the performance of the LUNs and from the filesystems space usage to the mirroring and snapshots mechanisms latency and to consolidate diversemonitoring needs within the Portal framework through a single solution

To setup a complete monitoring of the disk array we strongly recommend you to also use BMCPerformance Manager Express for Hardware that covers all the physical aspect of the disk array (statusof the disks ports temperature power supplies power consumption etc)

Being a Performance Manager specifically designed for BMC Portal BMC Performance ManagerExpress for EMC Disk Arrays uses the Portalrsquos web-based interface and features for installingmanaging and monitoring your infrastructure

Getting Started

11

BMC Performance Manager Express for EMC Disk Arrays

Version 2001

This chapter describes the prerequisites and the procedures you must perform before installing BMCPerformance Manager Express for EMC Disk Arrays Please follow the given instructions carefully inorder to ensure a successful integration of the solution within the Portal environment

Minimum Requirements

The computer on which you install BMC Performance Manager Express for EMC Disk Arrays shouldalready have

1 BMC Performance Manager Portal version 2500

2 Access to an RSM ie Remote Service Monitor

The RSM program must be installed on a Windows platform This can either be same as the serverwhere the Portal is installed or any other Windows computer on the network

Once you install BMC Performance Manager Express for EMC Disk Arrays you can add as manyelements as you require in your monitoring environment

Enabling the statistics

On EMC Clariion and VNX storage systems the statistics need to be enabled to allow BMCPerformance Manager Express for EMC Disk Arrays to collect statistics and to monitor performance

Using Navisphere

1 In Navisphere enable Statistics logging

middot Open Navisphere

middot Right-click the icon for the storage system

middot Click Properties

middot Be sure SP A and SP B are in the Storage Processors section

middot Click the box for Statistics Logging under the Configuration section

2 For locally attached CLARiiONs check if authorization info is present

3 Run the dv command from EMC TestSMIProvider Make sure all arrays are discovered withoutany errors

4 Make sure performance is turned on in the Profile for storage arrays

5 Make sure there are instances for the CIM_BlockStorageStatisticalData class

middot Run Tek-Tools testProvider or EMCrsquos testSMIProvider

middot Type ein for command

middot Type CIM_BlockStorageStatisticalData for Class Name

middot If no instances are returned reset EMC Provider

6 Once complete resume steps 1-3

If you are using a version older than SMIKit 642 the EMC SMI-S Provider does not recognize changes in the arraywhen a LUN or RAID Group is created or deleted from Navisphere It is thus recommended to upgrade your EMC SMI-SProvider to version 642 or higher to benefit from the auto-synchronization mechanism set by default to one hour afterthe last update If you do not upgrade your EMC SMI-S Provider you will have to run the refsys command fromtestsmiprovider each time you create or delete LUN or RAID groups from Navisphere

Managing Baselines and KeyPerformance IndicatorsIn order to facilitate the detection of abnormalities on your monitored environment BMCProactiveNet calculates baselines per parameter (metrics or attributes) based on values collectedover a specified period of time to determine a normal operating range When the collected values forthese parameters are out of range an alert is triggered

Some parameters are identified by default as Key Performance Indicators and therefore automaticallyincluded in the base lining calculation

42Managing Baselines and Key PerformanceIndicators

BMC Performance Manager Express for EMC Disk Arrays

Version 2001

Managing baselines

The baseline is the expected normal operating range for a metric or attribute of a monitor

The baseline is calculated by collecting the values for a monitorrsquos attributes and metrics over aspecified time period and establishing a low baseline value (consisting of the 10th percentile of all thevalues for a given time period) and a high baseline value (consisting of the 90th percentile of all thevalues for a given time period) taking a weighted average of these values over time A higher weightis given to the latest data being factored into the baseline average The accuracy of the baselineimproves over time

Requirements for baseline generation

For baselines to be generated for an attribute that abnormality threshold means that the thresholdexists and is not suppressed Additionally if the Key Performance Indicator (KPI) mode is active only those attributes that have anactive abnormality threshold and are also KPI attributes will have baselines generated for them

Absolute thresholds (with outside baseline) or signature thresholds do not satisfy these requirements

Managing Key Performance Indicators

The KPI attribute of a parameter can be activated or deactivated manually through the BMCProactiveNet Administration Console In this PM some parameters or attributes have beendesignated as important indicators of performance (KPIs) We do not recommend that these defaultsettings are modified

However advanced users may activate or deactivate KPIs from the BMC ProactiveNet AdministrationConsole

To add or remove Key Performance Indicator (KPI) attributes for amonitor type

1 In the Administration Console from the menu bar choose Tools gt KPI AdministrationThe KPI Administration dialog box is displayed

2 From the Monitor Type list choose the monitor type for which you want to add or remove KPIattributes A list of attributes for the selected monitor type is displayed

3 In the KPI column for the attributes that you want to add or remove as Key PerformanceIndicators

middot select the KPI check box to add the corresponding attribute as a KPI

middot deselect the KPI check box to remove the corresponding attribute from the KPIs for thatmonitor type

For complete and detailed information on this procedure please refer to the BMC ProactiveNet documentation availablefrom BMC Web site

BMC Performance Manager Express for EMC Disk Arrays monitors all of the performance metrics andusage statistics of your EMC disk arrays such as file disk space usage storage controller utilizationIOs on the diskscontrollersvolumes etc It continuously monitors the activity of each array and isalso able to build reports on past utilization statistics

To setup a complete monitoring of the array we strongly recommend you to also use BMCPerformance Manager Express for Hardware that covers all the physical aspect of the EMC diskarrays (status of the disks ports temperature power supplies power consumption etc)

This chapter explains how to use each monitoring tool ie a separate application class within theBMC Performance Manager Express for EMC Disk Arrays by Sentry Software solution

BMC Performance Manager Express for EMC Disk Arrays is a Performance Manager specifically designedfor BMC Portal consequently it uses the same common features and procedures of BMCreg Portal Thisdocument assumes that the user knows how to use the Portal and therefore explains procedures onlyrelated to BMC Performance Manager Express for EMC Disk Arrays and not on how to add ElementsElement Profiles etc Please refer to the BMC Portal documentation for details on how to use the Portal

Checking Available Spare Disks

To avoid any loss of critical data it is essential for a disk array to always maintain a pool of sparedisks that can replace the faulty disk when a disk failure occurs A disk array without any left sparedisk will not be able to keep the level of data safety and performance in case of a disk failure

The Spare Disk Count parameter of the SEN_EMC_ARRAY class reports the number of spare disksavailable for each disk array monitored with the solution By default a warning is triggered when nospare disk is available (Spare Disk Count is set to zero)

Verifying the Number of Available Spare Disks in Your EMC Disk Arrays

49Checking Available Spare Disks

BMC Performance Manager Express for EMC Disk Arrays

Version 2001

1 Select an element group in the tree view (the main Infrastructure group for example)

2 Click the Reports tab Create a report for the last 24 hours bottom 50 values of the Array|Spare Disk Count parameter of the EMC Disk Arrays application class for the BMC PerformanceManager Express for EMC Disk Arrays by Sentry Software solution

Detecting OversubscriptionSituations (Thin Provisioning)We call an oversubscription situation when

1 The storage pool is configured for thin provisioning (ldquothin storage poolrdquo)

2 The storage pool is oversubscribed ie the total disk space visible to the hosts (subscribers) isgreater than its actual capacity (this situation is normal for a thin pool since it is its very purpose)

3 The storage pool actual consumed capacity is nearing 100

Such situation is highly critical because the inability to allocate additional space to a LUN whenrequested by the subscriber host will lead to catastrophic data loss and corruption

When the conditions described above are met the solution sets the Oversubscription Situationparameter to 1 automatically raising a warning By default the warning for OversubscriptionSituation is issued when the Consumed Capacity Percentage parameter goes above 100 Thisthreshold can be configured in the input properties of the solution

50Detecting Oversubscription Situations (ThinProvisioning)

BMC Performance Manager Express for EMC Disk Arrays

Version 2001

Configuring Oversubscription Threshold

1 Click the EMC Disk Arrays icon and then the Configure tab

2 Edit the Oversubscription Situation Threshold () property to the appropriate value Whenthe Oversubscription Situation parameter triggers a warning it is highly recommended thatthe SAN administrators add capacity to the storage pool as soon as possible

Diagnosing Slow LUNs

If a system administrator complains that his servers are experiencing slow IOs performance and thatit is caused by the SAN you may want to verify the actual response time of the LUNs the server isrelying on

The Response Time parameter of the SEN_EMC_VOLUME class represents the average time it tookto complete the read and write operations on the LUN during the collection interval Typically theaverage response time is below 10 milliseconds You may also want to compare this value to theresponse time of the other LUNs to see whether one server is really getting worse IO performancethan another

Volume - Response Time Parameter

If the response time is low you will need to check the amount of data that is written and read onthis LUN The bad performance may simply be due to an abnormally large amount of data to processOtherwise the problem is maybe between the disk array and the server in the fiber links

51Enabling the Debug Mode

BMC Performance Manager Express for EMC Disk Arrays

Version 2001

Enabling the Debug Mode

By default BMC Performance Manager Express for EMC Disk Arrays sends only the most criticalinformation warning and error messages to the Application Collection Status parameter Mostoften this information is accurate enough to ensure that BMC Performance Manager Express for EMCDisk Arrays is functioning properly If you encounter an issue and wish to report it to customersupport you will be asked to enable the Debug Mode and provide the debug output to the supportteam

1 In the Configure tab gt under Tasks click Elements

2 Select the Element whose debug output you require and click Edit

3 Scroll down to Application Classes gt click the Application class for which you want toenable the debug mode gt click Edit

4 Select Yes from the drop-down Debug Mode list gt SaveBy default BMC Performance Manager Express for EMC Disk Arrays sends its debug output to RSM_HOMERSM(xx)serverrsmlogsen_debuglog

5 Wait for 15 minutes and then disable the debug mode by selecting No

6 Send the debug file to the support team

Pay attention to the file size -the debug output of BMC Performance Manager Express for EMC Disk Arrays could bevery large if enabled for several days

Identifying the Hosts that canAccess a LUNIn most SAN configurations each LUN belongs to a storage group whose host members are the onlyones authorized to access the LUN This is called LUN masking For each LUN the solution displaysits WWN the storage group to which it belongs to as well as the hosts member of this group Inmost cases identifying the storage group of a LUN is sufficient to recognize the server that is usingit

52Identifying LUNs not Owned by their Normal(Default) Storage Processor

BMC Performance Manager Express for EMC Disk Arrays

Version 2001

Identifying LUNs not Owned bytheir Normal (Default) StorageProcessorThe Owning Storage Processor parameter reports the name of the controller that handles IOsfor each LUN If a LUN is not currently handled by its normal (default) storage processors the nameof the default controller will be indicated as SP_B (default SP_A)rdquo

To identify LUNs that are not owned by their normal storage processor you simply need to list the Volume objects where the Owning Storage Processor parameter contains the string Default

Identifying Most Busy LUNs

To identify the LUNs that generate the most traffic on the disk array use the Read Byte Rate andWrite Byte Rate parameters of the LUN class that expose the data throughput for each LUN Usethese parameters to report on the total data traffic (per hour or per day) on each LUN in GB

To make sure that traffic is displayed cumulatively per hour select a time window of at least 12 hours in the graphwindow select at least 7 days to visualize per day cumulative data

1 In the Status tab click the Volume for which you need to check the LUNs activity then expandthe LUNs object to display the ReadWrite Byte Rate parameters

Version 2001

View ing a LUNs ReadW rite Byte Rate as a graph

Identifying a Storage Processor(Controllers) OverloadTo visualize the activity of a controller in an EMC disk array use the Processor Utilizationparameter of the SEN_EMC_CONTROLLER class A warning is issued when the processor utilizationgoes too high which means that the controllers cannot keep up with the load on the disk array It isthen important to identify what is overloading the controllers

The Response Time parameter of the SEN_EMC_CONTROLLER class represents the average time ittook the controller to process the read and write requests of the hosts The higher the ResponseTime goes the slower IOs the servers will get By default the solution triggers a warning when thecontroller takes more than 10 milliseconds on average to complete the IO requests and an alarmwhen the response time reaches 100 milliseconds

Monitoring the Efficiency of theCaching MechanismEach controller in an EMC disk array can be configured to use a specified amount of memory tocache the read andor write operations The solution reports the amount of memory configured byeach controller for the read and write operations

The Write Flush Byte Rate represents the rate in MBsec at which data is committed to the disk(ie physically written) This value is to be compared with the Write Byte Rate of the disk array

55Monitoring the Efficiency of the CachingMechanism

BMC Performance Manager Express for EMC Disk Arrays

Version 2001

Comparing W rite Flush Byte Rate w ith W rite Byte Rate

The Cache Dirty Pages Percentage parameter represents the amount in percentage of the writecache that has been modified by host write operations and not yet flushed to the disks Reaching100 means that write case is too small and cannot handle the flow of write operations

Checking the Cache Dirty Pages Percentage

Reclaiming Space of Unmapped(Unused) LUNsOver time as servers connected to a SAN get decommissioned administrators find an increasingnumber of unmapped LUNs or volumes that are no longer used by any server These LUNs whileunused still occupy disk space in the disk array Being able to identify such unmapped LUNs andreclaim the disk space uselessly consumed by these LUNs will help administrators avoid unnecessaryupgrades and extensions of their disk arrays

56Reporting a Disk Space Consumption

BMC Performance Manager Express for EMC Disk Arrays

Version 2001

Reporting a Disk SpaceConsumptionMaking sure that a disk array has enough remaining disk space available is critical for severalreasons

middot SAN administrators want to make sure to be able to provision disk space for new servers whenrequested as quickly as possible

middot The disk array itself may need additional disk space for specific features to work properly likeautomatic snapshots mirroring etc

middot If thin provisioning is used the remaining disk space becomes dramatically critical since theinability to allocate additional space to a LUN when requested by the subscriber host will lead tocatastrophic data loss and corruption

The disk space used is permanently monitored for each storage pool The Subscribed Capacityparameter of the Pool class represents the amount of disk space that has been made available tothe subscriber hosts or in other words the amount of disk space that is seen by the serversconnected to disk array

The Consumed Capacity parameter of the SEN_EMC_STORAGEPOOLS class represents the actualspace usage in the storage pool For thin pools (when thin provisioning is enabled on the disk array)this value is normally lower than the Subscribed Capacity as it is the main purpose of thinprovisioning For traditional pools the Consumed Capacity parameters has the same value as theSubscribed Capacity parameter as the entirety of the subscribed disk space is fully allocated inthe storage pool

The Consumed Capacity Percentage parameter is the most critical one as a storage pool usagenearing 100 means that SAN administrators will not be able to create new LUNs in the storagepool By default no alarm or warning threshold is set on this parameter as the fullness of a storagepool may be a normal situation However you can set alert thresholds on this parameter as it fitsyour needs

This chapter describes the prerequisites and the procedures you must perform before installing BMCPerformance Manager Express for EMC Disk Arrays Please follow the given instructions carefully inorder to ensure a successful integration of the solution within the Portal environment

Minimum Requirements

The computer on which you install BMC Performance Manager Express for EMC Disk Arrays shouldalready have

1 BMC Performance Manager Portal version 2500

2 Access to an RSM ie Remote Service Monitor

The RSM program must be installed on a Windows platform This can either be same as the serverwhere the Portal is installed or any other Windows computer on the network

Once you install BMC Performance Manager Express for EMC Disk Arrays you can add as manyelements as you require in your monitoring environment

Enabling the statistics

On EMC Clariion and VNX storage systems the statistics need to be enabled to allow BMCPerformance Manager Express for EMC Disk Arrays to collect statistics and to monitor performance

Using Navisphere

1 In Navisphere enable Statistics logging

middot Open Navisphere

middot Right-click the icon for the storage system

middot Click Properties

middot Be sure SP A and SP B are in the Storage Processors section

middot Click the box for Statistics Logging under the Configuration section

2 For locally attached CLARiiONs check if authorization info is present

3 Run the dv command from EMC TestSMIProvider Make sure all arrays are discovered withoutany errors

4 Make sure performance is turned on in the Profile for storage arrays

5 Make sure there are instances for the CIM_BlockStorageStatisticalData class

middot Run Tek-Tools testProvider or EMCrsquos testSMIProvider

middot Type ein for command

middot Type CIM_BlockStorageStatisticalData for Class Name

middot If no instances are returned reset EMC Provider

6 Once complete resume steps 1-3

If you are using a version older than SMIKit 642 the EMC SMI-S Provider does not recognize changes in the arraywhen a LUN or RAID Group is created or deleted from Navisphere It is thus recommended to upgrade your EMC SMI-SProvider to version 642 or higher to benefit from the auto-synchronization mechanism set by default to one hour afterthe last update If you do not upgrade your EMC SMI-S Provider you will have to run the refsys command fromtestsmiprovider each time you create or delete LUN or RAID groups from Navisphere

Managing Baselines and KeyPerformance IndicatorsIn order to facilitate the detection of abnormalities on your monitored environment BMCProactiveNet calculates baselines per parameter (metrics or attributes) based on values collectedover a specified period of time to determine a normal operating range When the collected values forthese parameters are out of range an alert is triggered

Some parameters are identified by default as Key Performance Indicators and therefore automaticallyincluded in the base lining calculation

42Managing Baselines and Key PerformanceIndicators

BMC Performance Manager Express for EMC Disk Arrays

Version 2001

Managing baselines

The baseline is the expected normal operating range for a metric or attribute of a monitor

The baseline is calculated by collecting the values for a monitorrsquos attributes and metrics over aspecified time period and establishing a low baseline value (consisting of the 10th percentile of all thevalues for a given time period) and a high baseline value (consisting of the 90th percentile of all thevalues for a given time period) taking a weighted average of these values over time A higher weightis given to the latest data being factored into the baseline average The accuracy of the baselineimproves over time

Requirements for baseline generation

For baselines to be generated for an attribute that abnormality threshold means that the thresholdexists and is not suppressed Additionally if the Key Performance Indicator (KPI) mode is active only those attributes that have anactive abnormality threshold and are also KPI attributes will have baselines generated for them

Absolute thresholds (with outside baseline) or signature thresholds do not satisfy these requirements

Managing Key Performance Indicators

The KPI attribute of a parameter can be activated or deactivated manually through the BMCProactiveNet Administration Console In this PM some parameters or attributes have beendesignated as important indicators of performance (KPIs) We do not recommend that these defaultsettings are modified

However advanced users may activate or deactivate KPIs from the BMC ProactiveNet AdministrationConsole

To add or remove Key Performance Indicator (KPI) attributes for amonitor type

1 In the Administration Console from the menu bar choose Tools gt KPI AdministrationThe KPI Administration dialog box is displayed

2 From the Monitor Type list choose the monitor type for which you want to add or remove KPIattributes A list of attributes for the selected monitor type is displayed

3 In the KPI column for the attributes that you want to add or remove as Key PerformanceIndicators

middot select the KPI check box to add the corresponding attribute as a KPI

middot deselect the KPI check box to remove the corresponding attribute from the KPIs for thatmonitor type

For complete and detailed information on this procedure please refer to the BMC ProactiveNet documentation availablefrom BMC Web site

To setup a complete monitoring of the array we strongly recommend you to also use BMCPerformance Manager Express for Hardware that covers all the physical aspect of the EMC diskarrays (status of the disks ports temperature power supplies power consumption etc)

This chapter explains how to use each monitoring tool ie a separate application class within theBMC Performance Manager Express for EMC Disk Arrays by Sentry Software solution

BMC Performance Manager Express for EMC Disk Arrays is a Performance Manager specifically designedfor BMC Portal consequently it uses the same common features and procedures of BMCreg Portal Thisdocument assumes that the user knows how to use the Portal and therefore explains procedures onlyrelated to BMC Performance Manager Express for EMC Disk Arrays and not on how to add ElementsElement Profiles etc Please refer to the BMC Portal documentation for details on how to use the Portal

Checking Available Spare Disks

To avoid any loss of critical data it is essential for a disk array to always maintain a pool of sparedisks that can replace the faulty disk when a disk failure occurs A disk array without any left sparedisk will not be able to keep the level of data safety and performance in case of a disk failure

The Spare Disk Count parameter of the SEN_EMC_ARRAY class reports the number of spare disksavailable for each disk array monitored with the solution By default a warning is triggered when nospare disk is available (Spare Disk Count is set to zero)

Verifying the Number of Available Spare Disks in Your EMC Disk Arrays

49Checking Available Spare Disks

BMC Performance Manager Express for EMC Disk Arrays

Version 2001

1 Select an element group in the tree view (the main Infrastructure group for example)

2 Click the Reports tab Create a report for the last 24 hours bottom 50 values of the Array|Spare Disk Count parameter of the EMC Disk Arrays application class for the BMC PerformanceManager Express for EMC Disk Arrays by Sentry Software solution

Detecting OversubscriptionSituations (Thin Provisioning)We call an oversubscription situation when

1 The storage pool is configured for thin provisioning (ldquothin storage poolrdquo)

2 The storage pool is oversubscribed ie the total disk space visible to the hosts (subscribers) isgreater than its actual capacity (this situation is normal for a thin pool since it is its very purpose)

3 The storage pool actual consumed capacity is nearing 100

Such situation is highly critical because the inability to allocate additional space to a LUN whenrequested by the subscriber host will lead to catastrophic data loss and corruption

When the conditions described above are met the solution sets the Oversubscription Situationparameter to 1 automatically raising a warning By default the warning for OversubscriptionSituation is issued when the Consumed Capacity Percentage parameter goes above 100 Thisthreshold can be configured in the input properties of the solution

50Detecting Oversubscription Situations (ThinProvisioning)

BMC Performance Manager Express for EMC Disk Arrays

Version 2001

Configuring Oversubscription Threshold

1 Click the EMC Disk Arrays icon and then the Configure tab

2 Edit the Oversubscription Situation Threshold () property to the appropriate value Whenthe Oversubscription Situation parameter triggers a warning it is highly recommended thatthe SAN administrators add capacity to the storage pool as soon as possible

Diagnosing Slow LUNs

If a system administrator complains that his servers are experiencing slow IOs performance and thatit is caused by the SAN you may want to verify the actual response time of the LUNs the server isrelying on

The Response Time parameter of the SEN_EMC_VOLUME class represents the average time it tookto complete the read and write operations on the LUN during the collection interval Typically theaverage response time is below 10 milliseconds You may also want to compare this value to theresponse time of the other LUNs to see whether one server is really getting worse IO performancethan another

Volume - Response Time Parameter

If the response time is low you will need to check the amount of data that is written and read onthis LUN The bad performance may simply be due to an abnormally large amount of data to processOtherwise the problem is maybe between the disk array and the server in the fiber links

51Enabling the Debug Mode

BMC Performance Manager Express for EMC Disk Arrays

Version 2001

Enabling the Debug Mode

By default BMC Performance Manager Express for EMC Disk Arrays sends only the most criticalinformation warning and error messages to the Application Collection Status parameter Mostoften this information is accurate enough to ensure that BMC Performance Manager Express for EMCDisk Arrays is functioning properly If you encounter an issue and wish to report it to customersupport you will be asked to enable the Debug Mode and provide the debug output to the supportteam

1 In the Configure tab gt under Tasks click Elements

2 Select the Element whose debug output you require and click Edit

3 Scroll down to Application Classes gt click the Application class for which you want toenable the debug mode gt click Edit

4 Select Yes from the drop-down Debug Mode list gt SaveBy default BMC Performance Manager Express for EMC Disk Arrays sends its debug output to RSM_HOMERSM(xx)serverrsmlogsen_debuglog

5 Wait for 15 minutes and then disable the debug mode by selecting No

6 Send the debug file to the support team

Pay attention to the file size -the debug output of BMC Performance Manager Express for EMC Disk Arrays could bevery large if enabled for several days

Identifying the Hosts that canAccess a LUNIn most SAN configurations each LUN belongs to a storage group whose host members are the onlyones authorized to access the LUN This is called LUN masking For each LUN the solution displaysits WWN the storage group to which it belongs to as well as the hosts member of this group Inmost cases identifying the storage group of a LUN is sufficient to recognize the server that is usingit

52Identifying LUNs not Owned by their Normal(Default) Storage Processor

BMC Performance Manager Express for EMC Disk Arrays

Version 2001

Identifying LUNs not Owned bytheir Normal (Default) StorageProcessorThe Owning Storage Processor parameter reports the name of the controller that handles IOsfor each LUN If a LUN is not currently handled by its normal (default) storage processors the nameof the default controller will be indicated as SP_B (default SP_A)rdquo

To identify LUNs that are not owned by their normal storage processor you simply need to list the Volume objects where the Owning Storage Processor parameter contains the string Default

Identifying Most Busy LUNs

To identify the LUNs that generate the most traffic on the disk array use the Read Byte Rate andWrite Byte Rate parameters of the LUN class that expose the data throughput for each LUN Usethese parameters to report on the total data traffic (per hour or per day) on each LUN in GB

To make sure that traffic is displayed cumulatively per hour select a time window of at least 12 hours in the graphwindow select at least 7 days to visualize per day cumulative data

1 In the Status tab click the Volume for which you need to check the LUNs activity then expandthe LUNs object to display the ReadWrite Byte Rate parameters

53Identifying Most Busy LUNs

54Identifying Most Busy LUNs

BMC Performance Manager Express for EMC Disk Arrays

Version 2001

View ing a LUNs ReadW rite Byte Rate as a graph

Identifying a Storage Processor(Controllers) OverloadTo visualize the activity of a controller in an EMC disk array use the Processor Utilizationparameter of the SEN_EMC_CONTROLLER class A warning is issued when the processor utilizationgoes too high which means that the controllers cannot keep up with the load on the disk array It isthen important to identify what is overloading the controllers

The Response Time parameter of the SEN_EMC_CONTROLLER class represents the average time ittook the controller to process the read and write requests of the hosts The higher the ResponseTime goes the slower IOs the servers will get By default the solution triggers a warning when thecontroller takes more than 10 milliseconds on average to complete the IO requests and an alarmwhen the response time reaches 100 milliseconds

Monitoring the Efficiency of theCaching MechanismEach controller in an EMC disk array can be configured to use a specified amount of memory tocache the read andor write operations The solution reports the amount of memory configured byeach controller for the read and write operations

The Write Flush Byte Rate represents the rate in MBsec at which data is committed to the disk(ie physically written) This value is to be compared with the Write Byte Rate of the disk array

55Monitoring the Efficiency of the CachingMechanism

BMC Performance Manager Express for EMC Disk Arrays

Version 2001

Comparing W rite Flush Byte Rate w ith W rite Byte Rate

The Cache Dirty Pages Percentage parameter represents the amount in percentage of the writecache that has been modified by host write operations and not yet flushed to the disks Reaching100 means that write case is too small and cannot handle the flow of write operations

Checking the Cache Dirty Pages Percentage

Reclaiming Space of Unmapped(Unused) LUNsOver time as servers connected to a SAN get decommissioned administrators find an increasingnumber of unmapped LUNs or volumes that are no longer used by any server These LUNs whileunused still occupy disk space in the disk array Being able to identify such unmapped LUNs andreclaim the disk space uselessly consumed by these LUNs will help administrators avoid unnecessaryupgrades and extensions of their disk arrays

56Reporting a Disk Space Consumption

BMC Performance Manager Express for EMC Disk Arrays

Version 2001

Reporting a Disk SpaceConsumptionMaking sure that a disk array has enough remaining disk space available is critical for severalreasons

middot SAN administrators want to make sure to be able to provision disk space for new servers whenrequested as quickly as possible

middot The disk array itself may need additional disk space for specific features to work properly likeautomatic snapshots mirroring etc

middot If thin provisioning is used the remaining disk space becomes dramatically critical since theinability to allocate additional space to a LUN when requested by the subscriber host will lead tocatastrophic data loss and corruption

The disk space used is permanently monitored for each storage pool The Subscribed Capacityparameter of the Pool class represents the amount of disk space that has been made available tothe subscriber hosts or in other words the amount of disk space that is seen by the serversconnected to disk array

The Consumed Capacity parameter of the SEN_EMC_STORAGEPOOLS class represents the actualspace usage in the storage pool For thin pools (when thin provisioning is enabled on the disk array)this value is normally lower than the Subscribed Capacity as it is the main purpose of thinprovisioning For traditional pools the Consumed Capacity parameters has the same value as theSubscribed Capacity parameter as the entirety of the subscribed disk space is fully allocated inthe storage pool

The Consumed Capacity Percentage parameter is the most critical one as a storage pool usagenearing 100 means that SAN administrators will not be able to create new LUNs in the storagepool By default no alarm or warning threshold is set on this parameter as the fullness of a storagepool may be a normal situation However you can set alert thresholds on this parameter as it fitsyour needs

BMC Performance Manager Express for EMC Disk Arrays

Version 2001

BMC Performance Manager Express for EMC Disk Arrays is an agent-less Performance Manager forthe BMC Portal environment It allows you to automatically discover and monitor every aspect of EMCdisk arrays from the general health of the array to the performance of the LUNs and from the filesystems space usage to the mirroring and snapshots mechanisms latency and to consolidate diversemonitoring needs within the Portal framework through a single solution

To setup a complete monitoring of the disk array we strongly recommend you to also use BMCPerformance Manager Express for Hardware that covers all the physical aspect of the disk array (statusof the disks ports temperature power supplies power consumption etc)

Being a Performance Manager specifically designed for BMC Portal BMC Performance ManagerExpress for EMC Disk Arrays uses the Portalrsquos web-based interface and features for installingmanaging and monitoring your infrastructure

Getting Started

11

BMC Performance Manager Express for EMC Disk Arrays

Version 2001

This chapter describes the prerequisites and the procedures you must perform before installing BMCPerformance Manager Express for EMC Disk Arrays Please follow the given instructions carefully inorder to ensure a successful integration of the solution within the Portal environment

Minimum Requirements

The computer on which you install BMC Performance Manager Express for EMC Disk Arrays shouldalready have

1 BMC Performance Manager Portal version 2500

2 Access to an RSM ie Remote Service Monitor

The RSM program must be installed on a Windows platform This can either be same as the serverwhere the Portal is installed or any other Windows computer on the network

Once you install BMC Performance Manager Express for EMC Disk Arrays you can add as manyelements as you require in your monitoring environment

Enabling the statistics

On EMC Clariion and VNX storage systems the statistics need to be enabled to allow BMCPerformance Manager Express for EMC Disk Arrays to collect statistics and to monitor performance

Using Navisphere

1 In Navisphere enable Statistics logging

middot Open Navisphere

middot Right-click the icon for the storage system

middot Click Properties

middot Be sure SP A and SP B are in the Storage Processors section

middot Click the box for Statistics Logging under the Configuration section

2 For locally attached CLARiiONs check if authorization info is present

3 Run the dv command from EMC TestSMIProvider Make sure all arrays are discovered withoutany errors

4 Make sure performance is turned on in the Profile for storage arrays

5 Make sure there are instances for the CIM_BlockStorageStatisticalData class

middot Run Tek-Tools testProvider or EMCrsquos testSMIProvider

middot Type ein for command

middot Type CIM_BlockStorageStatisticalData for Class Name

middot If no instances are returned reset EMC Provider

6 Once complete resume steps 1-3

If you are using a version older than SMIKit 642 the EMC SMI-S Provider does not recognize changes in the arraywhen a LUN or RAID Group is created or deleted from Navisphere It is thus recommended to upgrade your EMC SMI-SProvider to version 642 or higher to benefit from the auto-synchronization mechanism set by default to one hour afterthe last update If you do not upgrade your EMC SMI-S Provider you will have to run the refsys command fromtestsmiprovider each time you create or delete LUN or RAID groups from Navisphere

Managing Baselines and KeyPerformance IndicatorsIn order to facilitate the detection of abnormalities on your monitored environment BMCProactiveNet calculates baselines per parameter (metrics or attributes) based on values collectedover a specified period of time to determine a normal operating range When the collected values forthese parameters are out of range an alert is triggered

Some parameters are identified by default as Key Performance Indicators and therefore automaticallyincluded in the base lining calculation

42Managing Baselines and Key PerformanceIndicators

BMC Performance Manager Express for EMC Disk Arrays

Version 2001

Managing baselines

The baseline is the expected normal operating range for a metric or attribute of a monitor

The baseline is calculated by collecting the values for a monitorrsquos attributes and metrics over aspecified time period and establishing a low baseline value (consisting of the 10th percentile of all thevalues for a given time period) and a high baseline value (consisting of the 90th percentile of all thevalues for a given time period) taking a weighted average of these values over time A higher weightis given to the latest data being factored into the baseline average The accuracy of the baselineimproves over time

Requirements for baseline generation

For baselines to be generated for an attribute that abnormality threshold means that the thresholdexists and is not suppressed Additionally if the Key Performance Indicator (KPI) mode is active only those attributes that have anactive abnormality threshold and are also KPI attributes will have baselines generated for them

Absolute thresholds (with outside baseline) or signature thresholds do not satisfy these requirements

Managing Key Performance Indicators

The KPI attribute of a parameter can be activated or deactivated manually through the BMCProactiveNet Administration Console In this PM some parameters or attributes have beendesignated as important indicators of performance (KPIs) We do not recommend that these defaultsettings are modified

However advanced users may activate or deactivate KPIs from the BMC ProactiveNet AdministrationConsole

To add or remove Key Performance Indicator (KPI) attributes for amonitor type

1 In the Administration Console from the menu bar choose Tools gt KPI AdministrationThe KPI Administration dialog box is displayed

2 From the Monitor Type list choose the monitor type for which you want to add or remove KPIattributes A list of attributes for the selected monitor type is displayed

3 In the KPI column for the attributes that you want to add or remove as Key PerformanceIndicators

middot select the KPI check box to add the corresponding attribute as a KPI

middot deselect the KPI check box to remove the corresponding attribute from the KPIs for thatmonitor type

For complete and detailed information on this procedure please refer to the BMC ProactiveNet documentation availablefrom BMC Web site

BMC Performance Manager Express for EMC Disk Arrays is a Performance Manager specifically designedfor BMC Portal consequently it uses the same common features and procedures of BMCreg Portal Thisdocument assumes that the user knows how to use the Portal and therefore explains procedures onlyrelated to BMC Performance Manager Express for EMC Disk Arrays and not on how to add ElementsElement Profiles etc Please refer to the BMC Portal documentation for details on how to use the Portal

Checking Available Spare Disks

To avoid any loss of critical data it is essential for a disk array to always maintain a pool of sparedisks that can replace the faulty disk when a disk failure occurs A disk array without any left sparedisk will not be able to keep the level of data safety and performance in case of a disk failure

The Spare Disk Count parameter of the SEN_EMC_ARRAY class reports the number of spare disksavailable for each disk array monitored with the solution By default a warning is triggered when nospare disk is available (Spare Disk Count is set to zero)

Verifying the Number of Available Spare Disks in Your EMC Disk Arrays

49Checking Available Spare Disks

BMC Performance Manager Express for EMC Disk Arrays

Version 2001

1 Select an element group in the tree view (the main Infrastructure group for example)

2 Click the Reports tab Create a report for the last 24 hours bottom 50 values of the Array|Spare Disk Count parameter of the EMC Disk Arrays application class for the BMC PerformanceManager Express for EMC Disk Arrays by Sentry Software solution

Detecting OversubscriptionSituations (Thin Provisioning)We call an oversubscription situation when

1 The storage pool is configured for thin provisioning (ldquothin storage poolrdquo)

2 The storage pool is oversubscribed ie the total disk space visible to the hosts (subscribers) isgreater than its actual capacity (this situation is normal for a thin pool since it is its very purpose)

3 The storage pool actual consumed capacity is nearing 100

Such situation is highly critical because the inability to allocate additional space to a LUN whenrequested by the subscriber host will lead to catastrophic data loss and corruption

When the conditions described above are met the solution sets the Oversubscription Situationparameter to 1 automatically raising a warning By default the warning for OversubscriptionSituation is issued when the Consumed Capacity Percentage parameter goes above 100 Thisthreshold can be configured in the input properties of the solution

50Detecting Oversubscription Situations (ThinProvisioning)

BMC Performance Manager Express for EMC Disk Arrays

Version 2001

Configuring Oversubscription Threshold

1 Click the EMC Disk Arrays icon and then the Configure tab

2 Edit the Oversubscription Situation Threshold () property to the appropriate value Whenthe Oversubscription Situation parameter triggers a warning it is highly recommended thatthe SAN administrators add capacity to the storage pool as soon as possible

Diagnosing Slow LUNs

If a system administrator complains that his servers are experiencing slow IOs performance and thatit is caused by the SAN you may want to verify the actual response time of the LUNs the server isrelying on

The Response Time parameter of the SEN_EMC_VOLUME class represents the average time it tookto complete the read and write operations on the LUN during the collection interval Typically theaverage response time is below 10 milliseconds You may also want to compare this value to theresponse time of the other LUNs to see whether one server is really getting worse IO performancethan another

Volume - Response Time Parameter

If the response time is low you will need to check the amount of data that is written and read onthis LUN The bad performance may simply be due to an abnormally large amount of data to processOtherwise the problem is maybe between the disk array and the server in the fiber links

51Enabling the Debug Mode

BMC Performance Manager Express for EMC Disk Arrays

Version 2001

Enabling the Debug Mode

By default BMC Performance Manager Express for EMC Disk Arrays sends only the most criticalinformation warning and error messages to the Application Collection Status parameter Mostoften this information is accurate enough to ensure that BMC Performance Manager Express for EMCDisk Arrays is functioning properly If you encounter an issue and wish to report it to customersupport you will be asked to enable the Debug Mode and provide the debug output to the supportteam

1 In the Configure tab gt under Tasks click Elements

2 Select the Element whose debug output you require and click Edit

3 Scroll down to Application Classes gt click the Application class for which you want toenable the debug mode gt click Edit

4 Select Yes from the drop-down Debug Mode list gt SaveBy default BMC Performance Manager Express for EMC Disk Arrays sends its debug output to RSM_HOMERSM(xx)serverrsmlogsen_debuglog

5 Wait for 15 minutes and then disable the debug mode by selecting No

6 Send the debug file to the support team

Pay attention to the file size -the debug output of BMC Performance Manager Express for EMC Disk Arrays could bevery large if enabled for several days

Identifying the Hosts that canAccess a LUNIn most SAN configurations each LUN belongs to a storage group whose host members are the onlyones authorized to access the LUN This is called LUN masking For each LUN the solution displaysits WWN the storage group to which it belongs to as well as the hosts member of this group Inmost cases identifying the storage group of a LUN is sufficient to recognize the server that is usingit

52Identifying LUNs not Owned by their Normal(Default) Storage Processor

BMC Performance Manager Express for EMC Disk Arrays

Version 2001

Identifying LUNs not Owned bytheir Normal (Default) StorageProcessorThe Owning Storage Processor parameter reports the name of the controller that handles IOsfor each LUN If a LUN is not currently handled by its normal (default) storage processors the nameof the default controller will be indicated as SP_B (default SP_A)rdquo

To identify LUNs that are not owned by their normal storage processor you simply need to list the Volume objects where the Owning Storage Processor parameter contains the string Default

Identifying Most Busy LUNs

To identify the LUNs that generate the most traffic on the disk array use the Read Byte Rate andWrite Byte Rate parameters of the LUN class that expose the data throughput for each LUN Usethese parameters to report on the total data traffic (per hour or per day) on each LUN in GB

To make sure that traffic is displayed cumulatively per hour select a time window of at least 12 hours in the graphwindow select at least 7 days to visualize per day cumulative data

1 In the Status tab click the Volume for which you need to check the LUNs activity then expandthe LUNs object to display the ReadWrite Byte Rate parameters

BMC Performance Manager Express for EMC Disk Arrays

Version 2001

View ing a LUNs ReadW rite Byte Rate as a graph

Identifying a Storage Processor(Controllers) OverloadTo visualize the activity of a controller in an EMC disk array use the Processor Utilizationparameter of the SEN_EMC_CONTROLLER class A warning is issued when the processor utilizationgoes too high which means that the controllers cannot keep up with the load on the disk array It isthen important to identify what is overloading the controllers

The Response Time parameter of the SEN_EMC_CONTROLLER class represents the average time ittook the controller to process the read and write requests of the hosts The higher the ResponseTime goes the slower IOs the servers will get By default the solution triggers a warning when thecontroller takes more than 10 milliseconds on average to complete the IO requests and an alarmwhen the response time reaches 100 milliseconds

Monitoring the Efficiency of theCaching MechanismEach controller in an EMC disk array can be configured to use a specified amount of memory tocache the read andor write operations The solution reports the amount of memory configured byeach controller for the read and write operations

The Write Flush Byte Rate represents the rate in MBsec at which data is committed to the disk(ie physically written) This value is to be compared with the Write Byte Rate of the disk array

55Monitoring the Efficiency of the CachingMechanism

BMC Performance Manager Express for EMC Disk Arrays

Version 2001

Comparing W rite Flush Byte Rate w ith W rite Byte Rate

The Cache Dirty Pages Percentage parameter represents the amount in percentage of the writecache that has been modified by host write operations and not yet flushed to the disks Reaching100 means that write case is too small and cannot handle the flow of write operations

Checking the Cache Dirty Pages Percentage

Reclaiming Space of Unmapped(Unused) LUNsOver time as servers connected to a SAN get decommissioned administrators find an increasingnumber of unmapped LUNs or volumes that are no longer used by any server These LUNs whileunused still occupy disk space in the disk array Being able to identify such unmapped LUNs andreclaim the disk space uselessly consumed by these LUNs will help administrators avoid unnecessaryupgrades and extensions of their disk arrays

56Reporting a Disk Space Consumption

BMC Performance Manager Express for EMC Disk Arrays

Version 2001

Reporting a Disk SpaceConsumptionMaking sure that a disk array has enough remaining disk space available is critical for severalreasons

middot SAN administrators want to make sure to be able to provision disk space for new servers whenrequested as quickly as possible

middot The disk array itself may need additional disk space for specific features to work properly likeautomatic snapshots mirroring etc

middot If thin provisioning is used the remaining disk space becomes dramatically critical since theinability to allocate additional space to a LUN when requested by the subscriber host will lead tocatastrophic data loss and corruption

The disk space used is permanently monitored for each storage pool The Subscribed Capacityparameter of the Pool class represents the amount of disk space that has been made available tothe subscriber hosts or in other words the amount of disk space that is seen by the serversconnected to disk array

The Consumed Capacity parameter of the SEN_EMC_STORAGEPOOLS class represents the actualspace usage in the storage pool For thin pools (when thin provisioning is enabled on the disk array)this value is normally lower than the Subscribed Capacity as it is the main purpose of thinprovisioning For traditional pools the Consumed Capacity parameters has the same value as theSubscribed Capacity parameter as the entirety of the subscribed disk space is fully allocated inthe storage pool

The Consumed Capacity Percentage parameter is the most critical one as a storage pool usagenearing 100 means that SAN administrators will not be able to create new LUNs in the storagepool By default no alarm or warning threshold is set on this parameter as the fullness of a storagepool may be a normal situation However you can set alert thresholds on this parameter as it fitsyour needs

BMC Performance Manager Express for EMC Disk Arrays

Version 2001

BMC Performance Manager Express for EMC Disk Arrays is an agent-less Performance Manager forthe BMC Portal environment It allows you to automatically discover and monitor every aspect of EMCdisk arrays from the general health of the array to the performance of the LUNs and from the filesystems space usage to the mirroring and snapshots mechanisms latency and to consolidate diversemonitoring needs within the Portal framework through a single solution

To setup a complete monitoring of the disk array we strongly recommend you to also use BMCPerformance Manager Express for Hardware that covers all the physical aspect of the disk array (statusof the disks ports temperature power supplies power consumption etc)

Being a Performance Manager specifically designed for BMC Portal BMC Performance ManagerExpress for EMC Disk Arrays uses the Portalrsquos web-based interface and features for installingmanaging and monitoring your infrastructure

Getting Started

11

BMC Performance Manager Express for EMC Disk Arrays

Version 2001

This chapter describes the prerequisites and the procedures you must perform before installing BMCPerformance Manager Express for EMC Disk Arrays Please follow the given instructions carefully inorder to ensure a successful integration of the solution within the Portal environment

Minimum Requirements

The computer on which you install BMC Performance Manager Express for EMC Disk Arrays shouldalready have

1 BMC Performance Manager Portal version 2500

2 Access to an RSM ie Remote Service Monitor

The RSM program must be installed on a Windows platform This can either be same as the serverwhere the Portal is installed or any other Windows computer on the network

Once you install BMC Performance Manager Express for EMC Disk Arrays you can add as manyelements as you require in your monitoring environment

Enabling the statistics

On EMC Clariion and VNX storage systems the statistics need to be enabled to allow BMCPerformance Manager Express for EMC Disk Arrays to collect statistics and to monitor performance

Using Navisphere

1 In Navisphere enable Statistics logging

middot Open Navisphere

middot Right-click the icon for the storage system

middot Click Properties

middot Be sure SP A and SP B are in the Storage Processors section

middot Click the box for Statistics Logging under the Configuration section

2 For locally attached CLARiiONs check if authorization info is present

3 Run the dv command from EMC TestSMIProvider Make sure all arrays are discovered withoutany errors

4 Make sure performance is turned on in the Profile for storage arrays

5 Make sure there are instances for the CIM_BlockStorageStatisticalData class

middot Run Tek-Tools testProvider or EMCrsquos testSMIProvider

middot Type ein for command

middot Type CIM_BlockStorageStatisticalData for Class Name

middot If no instances are returned reset EMC Provider

6 Once complete resume steps 1-3

If you are using a version older than SMIKit 642 the EMC SMI-S Provider does not recognize changes in the arraywhen a LUN or RAID Group is created or deleted from Navisphere It is thus recommended to upgrade your EMC SMI-SProvider to version 642 or higher to benefit from the auto-synchronization mechanism set by default to one hour afterthe last update If you do not upgrade your EMC SMI-S Provider you will have to run the refsys command fromtestsmiprovider each time you create or delete LUN or RAID groups from Navisphere

Managing Baselines and KeyPerformance IndicatorsIn order to facilitate the detection of abnormalities on your monitored environment BMCProactiveNet calculates baselines per parameter (metrics or attributes) based on values collectedover a specified period of time to determine a normal operating range When the collected values forthese parameters are out of range an alert is triggered

Some parameters are identified by default as Key Performance Indicators and therefore automaticallyincluded in the base lining calculation

42Managing Baselines and Key PerformanceIndicators

BMC Performance Manager Express for EMC Disk Arrays

Version 2001

Managing baselines

The baseline is the expected normal operating range for a metric or attribute of a monitor

The baseline is calculated by collecting the values for a monitorrsquos attributes and metrics over aspecified time period and establishing a low baseline value (consisting of the 10th percentile of all thevalues for a given time period) and a high baseline value (consisting of the 90th percentile of all thevalues for a given time period) taking a weighted average of these values over time A higher weightis given to the latest data being factored into the baseline average The accuracy of the baselineimproves over time

Requirements for baseline generation

For baselines to be generated for an attribute that abnormality threshold means that the thresholdexists and is not suppressed Additionally if the Key Performance Indicator (KPI) mode is active only those attributes that have anactive abnormality threshold and are also KPI attributes will have baselines generated for them

Absolute thresholds (with outside baseline) or signature thresholds do not satisfy these requirements

Managing Key Performance Indicators

The KPI attribute of a parameter can be activated or deactivated manually through the BMCProactiveNet Administration Console In this PM some parameters or attributes have beendesignated as important indicators of performance (KPIs) We do not recommend that these defaultsettings are modified

However advanced users may activate or deactivate KPIs from the BMC ProactiveNet AdministrationConsole

To add or remove Key Performance Indicator (KPI) attributes for amonitor type

1 In the Administration Console from the menu bar choose Tools gt KPI AdministrationThe KPI Administration dialog box is displayed

2 From the Monitor Type list choose the monitor type for which you want to add or remove KPIattributes A list of attributes for the selected monitor type is displayed

3 In the KPI column for the attributes that you want to add or remove as Key PerformanceIndicators

middot select the KPI check box to add the corresponding attribute as a KPI

middot deselect the KPI check box to remove the corresponding attribute from the KPIs for thatmonitor type

For complete and detailed information on this procedure please refer to the BMC ProactiveNet documentation availablefrom BMC Web site

Checking Available Spare Disks

To avoid any loss of critical data it is essential for a disk array to always maintain a pool of sparedisks that can replace the faulty disk when a disk failure occurs A disk array without any left sparedisk will not be able to keep the level of data safety and performance in case of a disk failure

The Spare Disk Count parameter of the SEN_EMC_ARRAY class reports the number of spare disksavailable for each disk array monitored with the solution By default a warning is triggered when nospare disk is available (Spare Disk Count is set to zero)

Verifying the Number of Available Spare Disks in Your EMC Disk Arrays

49Checking Available Spare Disks

BMC Performance Manager Express for EMC Disk Arrays

Version 2001

1 Select an element group in the tree view (the main Infrastructure group for example)

2 Click the Reports tab Create a report for the last 24 hours bottom 50 values of the Array|Spare Disk Count parameter of the EMC Disk Arrays application class for the BMC PerformanceManager Express for EMC Disk Arrays by Sentry Software solution

Detecting OversubscriptionSituations (Thin Provisioning)We call an oversubscription situation when

1 The storage pool is configured for thin provisioning (ldquothin storage poolrdquo)

2 The storage pool is oversubscribed ie the total disk space visible to the hosts (subscribers) isgreater than its actual capacity (this situation is normal for a thin pool since it is its very purpose)

3 The storage pool actual consumed capacity is nearing 100

Such situation is highly critical because the inability to allocate additional space to a LUN whenrequested by the subscriber host will lead to catastrophic data loss and corruption

When the conditions described above are met the solution sets the Oversubscription Situationparameter to 1 automatically raising a warning By default the warning for OversubscriptionSituation is issued when the Consumed Capacity Percentage parameter goes above 100 Thisthreshold can be configured in the input properties of the solution

50Detecting Oversubscription Situations (ThinProvisioning)

BMC Performance Manager Express for EMC Disk Arrays

Version 2001

Configuring Oversubscription Threshold

1 Click the EMC Disk Arrays icon and then the Configure tab

2 Edit the Oversubscription Situation Threshold () property to the appropriate value Whenthe Oversubscription Situation parameter triggers a warning it is highly recommended thatthe SAN administrators add capacity to the storage pool as soon as possible

Diagnosing Slow LUNs

If a system administrator complains that his servers are experiencing slow IOs performance and thatit is caused by the SAN you may want to verify the actual response time of the LUNs the server isrelying on

The Response Time parameter of the SEN_EMC_VOLUME class represents the average time it tookto complete the read and write operations on the LUN during the collection interval Typically theaverage response time is below 10 milliseconds You may also want to compare this value to theresponse time of the other LUNs to see whether one server is really getting worse IO performancethan another

Volume - Response Time Parameter

If the response time is low you will need to check the amount of data that is written and read onthis LUN The bad performance may simply be due to an abnormally large amount of data to processOtherwise the problem is maybe between the disk array and the server in the fiber links

51Enabling the Debug Mode

BMC Performance Manager Express for EMC Disk Arrays

Version 2001

Enabling the Debug Mode

By default BMC Performance Manager Express for EMC Disk Arrays sends only the most criticalinformation warning and error messages to the Application Collection Status parameter Mostoften this information is accurate enough to ensure that BMC Performance Manager Express for EMCDisk Arrays is functioning properly If you encounter an issue and wish to report it to customersupport you will be asked to enable the Debug Mode and provide the debug output to the supportteam

1 In the Configure tab gt under Tasks click Elements

2 Select the Element whose debug output you require and click Edit

3 Scroll down to Application Classes gt click the Application class for which you want toenable the debug mode gt click Edit

4 Select Yes from the drop-down Debug Mode list gt SaveBy default BMC Performance Manager Express for EMC Disk Arrays sends its debug output to RSM_HOMERSM(xx)serverrsmlogsen_debuglog

5 Wait for 15 minutes and then disable the debug mode by selecting No

6 Send the debug file to the support team

Pay attention to the file size -the debug output of BMC Performance Manager Express for EMC Disk Arrays could bevery large if enabled for several days

Identifying the Hosts that canAccess a LUNIn most SAN configurations each LUN belongs to a storage group whose host members are the onlyones authorized to access the LUN This is called LUN masking For each LUN the solution displaysits WWN the storage group to which it belongs to as well as the hosts member of this group Inmost cases identifying the storage group of a LUN is sufficient to recognize the server that is usingit

52Identifying LUNs not Owned by their Normal(Default) Storage Processor

BMC Performance Manager Express for EMC Disk Arrays

Version 2001

Identifying LUNs not Owned bytheir Normal (Default) StorageProcessorThe Owning Storage Processor parameter reports the name of the controller that handles IOsfor each LUN If a LUN is not currently handled by its normal (default) storage processors the nameof the default controller will be indicated as SP_B (default SP_A)rdquo

To identify LUNs that are not owned by their normal storage processor you simply need to list the Volume objects where the Owning Storage Processor parameter contains the string Default

Identifying Most Busy LUNs

To identify the LUNs that generate the most traffic on the disk array use the Read Byte Rate andWrite Byte Rate parameters of the LUN class that expose the data throughput for each LUN Usethese parameters to report on the total data traffic (per hour or per day) on each LUN in GB

To make sure that traffic is displayed cumulatively per hour select a time window of at least 12 hours in the graphwindow select at least 7 days to visualize per day cumulative data

1 In the Status tab click the Volume for which you need to check the LUNs activity then expandthe LUNs object to display the ReadWrite Byte Rate parameters

54Identifying Most Busy LUNs

BMC Performance Manager Express for EMC Disk Arrays

Version 2001

View ing a LUNs ReadW rite Byte Rate as a graph

Identifying a Storage Processor(Controllers) OverloadTo visualize the activity of a controller in an EMC disk array use the Processor Utilizationparameter of the SEN_EMC_CONTROLLER class A warning is issued when the processor utilizationgoes too high which means that the controllers cannot keep up with the load on the disk array It isthen important to identify what is overloading the controllers

The Response Time parameter of the SEN_EMC_CONTROLLER class represents the average time ittook the controller to process the read and write requests of the hosts The higher the ResponseTime goes the slower IOs the servers will get By default the solution triggers a warning when thecontroller takes more than 10 milliseconds on average to complete the IO requests and an alarmwhen the response time reaches 100 milliseconds

Monitoring the Efficiency of theCaching MechanismEach controller in an EMC disk array can be configured to use a specified amount of memory tocache the read andor write operations The solution reports the amount of memory configured byeach controller for the read and write operations

The Write Flush Byte Rate represents the rate in MBsec at which data is committed to the disk(ie physically written) This value is to be compared with the Write Byte Rate of the disk array

55Monitoring the Efficiency of the CachingMechanism

BMC Performance Manager Express for EMC Disk Arrays

Version 2001

Comparing W rite Flush Byte Rate w ith W rite Byte Rate

The Cache Dirty Pages Percentage parameter represents the amount in percentage of the writecache that has been modified by host write operations and not yet flushed to the disks Reaching100 means that write case is too small and cannot handle the flow of write operations

Checking the Cache Dirty Pages Percentage

Reclaiming Space of Unmapped(Unused) LUNsOver time as servers connected to a SAN get decommissioned administrators find an increasingnumber of unmapped LUNs or volumes that are no longer used by any server These LUNs whileunused still occupy disk space in the disk array Being able to identify such unmapped LUNs andreclaim the disk space uselessly consumed by these LUNs will help administrators avoid unnecessaryupgrades and extensions of their disk arrays

56Reporting a Disk Space Consumption

BMC Performance Manager Express for EMC Disk Arrays

Version 2001

Reporting a Disk SpaceConsumptionMaking sure that a disk array has enough remaining disk space available is critical for severalreasons

middot SAN administrators want to make sure to be able to provision disk space for new servers whenrequested as quickly as possible

middot The disk array itself may need additional disk space for specific features to work properly likeautomatic snapshots mirroring etc

middot If thin provisioning is used the remaining disk space becomes dramatically critical since theinability to allocate additional space to a LUN when requested by the subscriber host will lead tocatastrophic data loss and corruption

The disk space used is permanently monitored for each storage pool The Subscribed Capacityparameter of the Pool class represents the amount of disk space that has been made available tothe subscriber hosts or in other words the amount of disk space that is seen by the serversconnected to disk array

The Consumed Capacity parameter of the SEN_EMC_STORAGEPOOLS class represents the actualspace usage in the storage pool For thin pools (when thin provisioning is enabled on the disk array)this value is normally lower than the Subscribed Capacity as it is the main purpose of thinprovisioning For traditional pools the Consumed Capacity parameters has the same value as theSubscribed Capacity parameter as the entirety of the subscribed disk space is fully allocated inthe storage pool

The Consumed Capacity Percentage parameter is the most critical one as a storage pool usagenearing 100 means that SAN administrators will not be able to create new LUNs in the storagepool By default no alarm or warning threshold is set on this parameter as the fullness of a storagepool may be a normal situation However you can set alert thresholds on this parameter as it fitsyour needs

BMC Performance Manager Express for EMC Disk Arrays

Version 2001

BMC Performance Manager Express for EMC Disk Arrays is an agent-less Performance Manager forthe BMC Portal environment It allows you to automatically discover and monitor every aspect of EMCdisk arrays from the general health of the array to the performance of the LUNs and from the filesystems space usage to the mirroring and snapshots mechanisms latency and to consolidate diversemonitoring needs within the Portal framework through a single solution

To setup a complete monitoring of the disk array we strongly recommend you to also use BMCPerformance Manager Express for Hardware that covers all the physical aspect of the disk array (statusof the disks ports temperature power supplies power consumption etc)

Being a Performance Manager specifically designed for BMC Portal BMC Performance ManagerExpress for EMC Disk Arrays uses the Portalrsquos web-based interface and features for installingmanaging and monitoring your infrastructure

Getting Started

11

BMC Performance Manager Express for EMC Disk Arrays

Version 2001

This chapter describes the prerequisites and the procedures you must perform before installing BMCPerformance Manager Express for EMC Disk Arrays Please follow the given instructions carefully inorder to ensure a successful integration of the solution within the Portal environment

Minimum Requirements

The computer on which you install BMC Performance Manager Express for EMC Disk Arrays shouldalready have

1 BMC Performance Manager Portal version 2500

2 Access to an RSM ie Remote Service Monitor

The RSM program must be installed on a Windows platform This can either be same as the serverwhere the Portal is installed or any other Windows computer on the network

Once you install BMC Performance Manager Express for EMC Disk Arrays you can add as manyelements as you require in your monitoring environment

Enabling the statistics

On EMC Clariion and VNX storage systems the statistics need to be enabled to allow BMCPerformance Manager Express for EMC Disk Arrays to collect statistics and to monitor performance

Using Navisphere

1 In Navisphere enable Statistics logging

middot Open Navisphere

middot Right-click the icon for the storage system

middot Click Properties

middot Be sure SP A and SP B are in the Storage Processors section

middot Click the box for Statistics Logging under the Configuration section

2 For locally attached CLARiiONs check if authorization info is present

3 Run the dv command from EMC TestSMIProvider Make sure all arrays are discovered withoutany errors

4 Make sure performance is turned on in the Profile for storage arrays

5 Make sure there are instances for the CIM_BlockStorageStatisticalData class

middot Run Tek-Tools testProvider or EMCrsquos testSMIProvider

middot Type ein for command

middot Type CIM_BlockStorageStatisticalData for Class Name

middot If no instances are returned reset EMC Provider

6 Once complete resume steps 1-3

If you are using a version older than SMIKit 642 the EMC SMI-S Provider does not recognize changes in the arraywhen a LUN or RAID Group is created or deleted from Navisphere It is thus recommended to upgrade your EMC SMI-SProvider to version 642 or higher to benefit from the auto-synchronization mechanism set by default to one hour afterthe last update If you do not upgrade your EMC SMI-S Provider you will have to run the refsys command fromtestsmiprovider each time you create or delete LUN or RAID groups from Navisphere

Managing Baselines and KeyPerformance IndicatorsIn order to facilitate the detection of abnormalities on your monitored environment BMCProactiveNet calculates baselines per parameter (metrics or attributes) based on values collectedover a specified period of time to determine a normal operating range When the collected values forthese parameters are out of range an alert is triggered

Some parameters are identified by default as Key Performance Indicators and therefore automaticallyincluded in the base lining calculation

42Managing Baselines and Key PerformanceIndicators

BMC Performance Manager Express for EMC Disk Arrays

Version 2001

Managing baselines

The baseline is the expected normal operating range for a metric or attribute of a monitor

The baseline is calculated by collecting the values for a monitorrsquos attributes and metrics over aspecified time period and establishing a low baseline value (consisting of the 10th percentile of all thevalues for a given time period) and a high baseline value (consisting of the 90th percentile of all thevalues for a given time period) taking a weighted average of these values over time A higher weightis given to the latest data being factored into the baseline average The accuracy of the baselineimproves over time

Requirements for baseline generation

For baselines to be generated for an attribute that abnormality threshold means that the thresholdexists and is not suppressed Additionally if the Key Performance Indicator (KPI) mode is active only those attributes that have anactive abnormality threshold and are also KPI attributes will have baselines generated for them

Absolute thresholds (with outside baseline) or signature thresholds do not satisfy these requirements

Managing Key Performance Indicators

The KPI attribute of a parameter can be activated or deactivated manually through the BMCProactiveNet Administration Console In this PM some parameters or attributes have beendesignated as important indicators of performance (KPIs) We do not recommend that these defaultsettings are modified

However advanced users may activate or deactivate KPIs from the BMC ProactiveNet AdministrationConsole

To add or remove Key Performance Indicator (KPI) attributes for amonitor type

1 In the Administration Console from the menu bar choose Tools gt KPI AdministrationThe KPI Administration dialog box is displayed

2 From the Monitor Type list choose the monitor type for which you want to add or remove KPIattributes A list of attributes for the selected monitor type is displayed

3 In the KPI column for the attributes that you want to add or remove as Key PerformanceIndicators

middot select the KPI check box to add the corresponding attribute as a KPI

middot deselect the KPI check box to remove the corresponding attribute from the KPIs for thatmonitor type

For complete and detailed information on this procedure please refer to the BMC ProactiveNet documentation availablefrom BMC Web site

Checking Available Spare Disks

To avoid any loss of critical data it is essential for a disk array to always maintain a pool of sparedisks that can replace the faulty disk when a disk failure occurs A disk array without any left sparedisk will not be able to keep the level of data safety and performance in case of a disk failure

The Spare Disk Count parameter of the SEN_EMC_ARRAY class reports the number of spare disksavailable for each disk array monitored with the solution By default a warning is triggered when nospare disk is available (Spare Disk Count is set to zero)

Verifying the Number of Available Spare Disks in Your EMC Disk Arrays

49Checking Available Spare Disks

BMC Performance Manager Express for EMC Disk Arrays

Version 2001

1 Select an element group in the tree view (the main Infrastructure group for example)

2 Click the Reports tab Create a report for the last 24 hours bottom 50 values of the Array|Spare Disk Count parameter of the EMC Disk Arrays application class for the BMC PerformanceManager Express for EMC Disk Arrays by Sentry Software solution

Detecting OversubscriptionSituations (Thin Provisioning)We call an oversubscription situation when

1 The storage pool is configured for thin provisioning (ldquothin storage poolrdquo)

2 The storage pool is oversubscribed ie the total disk space visible to the hosts (subscribers) isgreater than its actual capacity (this situation is normal for a thin pool since it is its very purpose)

3 The storage pool actual consumed capacity is nearing 100

Such situation is highly critical because the inability to allocate additional space to a LUN whenrequested by the subscriber host will lead to catastrophic data loss and corruption

When the conditions described above are met the solution sets the Oversubscription Situationparameter to 1 automatically raising a warning By default the warning for OversubscriptionSituation is issued when the Consumed Capacity Percentage parameter goes above 100 Thisthreshold can be configured in the input properties of the solution

50Detecting Oversubscription Situations (ThinProvisioning)

BMC Performance Manager Express for EMC Disk Arrays

Version 2001

Configuring Oversubscription Threshold

1 Click the EMC Disk Arrays icon and then the Configure tab

2 Edit the Oversubscription Situation Threshold () property to the appropriate value Whenthe Oversubscription Situation parameter triggers a warning it is highly recommended thatthe SAN administrators add capacity to the storage pool as soon as possible

Diagnosing Slow LUNs

If a system administrator complains that his servers are experiencing slow IOs performance and thatit is caused by the SAN you may want to verify the actual response time of the LUNs the server isrelying on

The Response Time parameter of the SEN_EMC_VOLUME class represents the average time it tookto complete the read and write operations on the LUN during the collection interval Typically theaverage response time is below 10 milliseconds You may also want to compare this value to theresponse time of the other LUNs to see whether one server is really getting worse IO performancethan another

Volume - Response Time Parameter

If the response time is low you will need to check the amount of data that is written and read onthis LUN The bad performance may simply be due to an abnormally large amount of data to processOtherwise the problem is maybe between the disk array and the server in the fiber links

51Enabling the Debug Mode

BMC Performance Manager Express for EMC Disk Arrays

Version 2001

Enabling the Debug Mode

By default BMC Performance Manager Express for EMC Disk Arrays sends only the most criticalinformation warning and error messages to the Application Collection Status parameter Mostoften this information is accurate enough to ensure that BMC Performance Manager Express for EMCDisk Arrays is functioning properly If you encounter an issue and wish to report it to customersupport you will be asked to enable the Debug Mode and provide the debug output to the supportteam

1 In the Configure tab gt under Tasks click Elements

2 Select the Element whose debug output you require and click Edit

3 Scroll down to Application Classes gt click the Application class for which you want toenable the debug mode gt click Edit

4 Select Yes from the drop-down Debug Mode list gt SaveBy default BMC Performance Manager Express for EMC Disk Arrays sends its debug output to RSM_HOMERSM(xx)serverrsmlogsen_debuglog

5 Wait for 15 minutes and then disable the debug mode by selecting No

6 Send the debug file to the support team

Pay attention to the file size -the debug output of BMC Performance Manager Express for EMC Disk Arrays could bevery large if enabled for several days

Identifying the Hosts that canAccess a LUNIn most SAN configurations each LUN belongs to a storage group whose host members are the onlyones authorized to access the LUN This is called LUN masking For each LUN the solution displaysits WWN the storage group to which it belongs to as well as the hosts member of this group Inmost cases identifying the storage group of a LUN is sufficient to recognize the server that is usingit

52Identifying LUNs not Owned by their Normal(Default) Storage Processor

BMC Performance Manager Express for EMC Disk Arrays

Version 2001

Identifying LUNs not Owned bytheir Normal (Default) StorageProcessorThe Owning Storage Processor parameter reports the name of the controller that handles IOsfor each LUN If a LUN is not currently handled by its normal (default) storage processors the nameof the default controller will be indicated as SP_B (default SP_A)rdquo

To identify LUNs that are not owned by their normal storage processor you simply need to list the Volume objects where the Owning Storage Processor parameter contains the string Default

Identifying Most Busy LUNs

To identify the LUNs that generate the most traffic on the disk array use the Read Byte Rate andWrite Byte Rate parameters of the LUN class that expose the data throughput for each LUN Usethese parameters to report on the total data traffic (per hour or per day) on each LUN in GB

To make sure that traffic is displayed cumulatively per hour select a time window of at least 12 hours in the graphwindow select at least 7 days to visualize per day cumulative data

1 In the Status tab click the Volume for which you need to check the LUNs activity then expandthe LUNs object to display the ReadWrite Byte Rate parameters

53Identifying Most Busy LUNs

54Identifying Most Busy LUNs

BMC Performance Manager Express for EMC Disk Arrays

Version 2001

View ing a LUNs ReadW rite Byte Rate as a graph

Identifying a Storage Processor(Controllers) OverloadTo visualize the activity of a controller in an EMC disk array use the Processor Utilizationparameter of the SEN_EMC_CONTROLLER class A warning is issued when the processor utilizationgoes too high which means that the controllers cannot keep up with the load on the disk array It isthen important to identify what is overloading the controllers

The Response Time parameter of the SEN_EMC_CONTROLLER class represents the average time ittook the controller to process the read and write requests of the hosts The higher the ResponseTime goes the slower IOs the servers will get By default the solution triggers a warning when thecontroller takes more than 10 milliseconds on average to complete the IO requests and an alarmwhen the response time reaches 100 milliseconds

Monitoring the Efficiency of theCaching MechanismEach controller in an EMC disk array can be configured to use a specified amount of memory tocache the read andor write operations The solution reports the amount of memory configured byeach controller for the read and write operations

The Write Flush Byte Rate represents the rate in MBsec at which data is committed to the disk(ie physically written) This value is to be compared with the Write Byte Rate of the disk array

55Monitoring the Efficiency of the CachingMechanism

BMC Performance Manager Express for EMC Disk Arrays

Version 2001

Comparing W rite Flush Byte Rate w ith W rite Byte Rate

The Cache Dirty Pages Percentage parameter represents the amount in percentage of the writecache that has been modified by host write operations and not yet flushed to the disks Reaching100 means that write case is too small and cannot handle the flow of write operations

Checking the Cache Dirty Pages Percentage

Reclaiming Space of Unmapped(Unused) LUNsOver time as servers connected to a SAN get decommissioned administrators find an increasingnumber of unmapped LUNs or volumes that are no longer used by any server These LUNs whileunused still occupy disk space in the disk array Being able to identify such unmapped LUNs andreclaim the disk space uselessly consumed by these LUNs will help administrators avoid unnecessaryupgrades and extensions of their disk arrays

56Reporting a Disk Space Consumption

BMC Performance Manager Express for EMC Disk Arrays

Version 2001

Reporting a Disk SpaceConsumptionMaking sure that a disk array has enough remaining disk space available is critical for severalreasons

middot SAN administrators want to make sure to be able to provision disk space for new servers whenrequested as quickly as possible

middot The disk array itself may need additional disk space for specific features to work properly likeautomatic snapshots mirroring etc

middot If thin provisioning is used the remaining disk space becomes dramatically critical since theinability to allocate additional space to a LUN when requested by the subscriber host will lead tocatastrophic data loss and corruption

The disk space used is permanently monitored for each storage pool The Subscribed Capacityparameter of the Pool class represents the amount of disk space that has been made available tothe subscriber hosts or in other words the amount of disk space that is seen by the serversconnected to disk array

The Consumed Capacity parameter of the SEN_EMC_STORAGEPOOLS class represents the actualspace usage in the storage pool For thin pools (when thin provisioning is enabled on the disk array)this value is normally lower than the Subscribed Capacity as it is the main purpose of thinprovisioning For traditional pools the Consumed Capacity parameters has the same value as theSubscribed Capacity parameter as the entirety of the subscribed disk space is fully allocated inthe storage pool

The Consumed Capacity Percentage parameter is the most critical one as a storage pool usagenearing 100 means that SAN administrators will not be able to create new LUNs in the storagepool By default no alarm or warning threshold is set on this parameter as the fullness of a storagepool may be a normal situation However you can set alert thresholds on this parameter as it fitsyour needs

Setting thresholds

Whenever relevant BMC Performance Manager Express for EMC Disk Arrays automatically setsthresholds for parameters If you prefer a more fault-tolerant monitoring you can modify thethresholds of each parameter through the Configure tab gt Edit Thresholds

It is strongly recommended to wait for all the storage objects to be discovered before setting threshold values to avoidhaving to enter thresholds for each occurrence of the application class

To modify the parameter thresholds of several storage objects of an element

60Setting thresholds

BMC Performance Manager Express for EMC Disk Arrays

Version 2001

1 In the Configure tab click on the Storage (ltplatformgt) or the instance icon gt Edit

Thresholds Properties and Credentials

Any modification to the thresholds or any other properties of elements created using the Element

Profile mode is to be done using the Element Profile route or by clicking Override Profile

2 Uncheck the Warning and Alarm boxes for all the parameters for which you want to disablethe alert conditions

BMC Performance Manager Express for EMC Disk Arrays

Version 2001

BMC Performance Manager Express for EMC Disk Arrays is an agent-less Performance Manager forthe BMC Portal environment It allows you to automatically discover and monitor every aspect of EMCdisk arrays from the general health of the array to the performance of the LUNs and from the filesystems space usage to the mirroring and snapshots mechanisms latency and to consolidate diversemonitoring needs within the Portal framework through a single solution

To setup a complete monitoring of the disk array we strongly recommend you to also use BMCPerformance Manager Express for Hardware that covers all the physical aspect of the disk array (statusof the disks ports temperature power supplies power consumption etc)

Being a Performance Manager specifically designed for BMC Portal BMC Performance ManagerExpress for EMC Disk Arrays uses the Portalrsquos web-based interface and features for installingmanaging and monitoring your infrastructure

Getting Started

11

BMC Performance Manager Express for EMC Disk Arrays

Version 2001

This chapter describes the prerequisites and the procedures you must perform before installing BMCPerformance Manager Express for EMC Disk Arrays Please follow the given instructions carefully inorder to ensure a successful integration of the solution within the Portal environment

Minimum Requirements

The computer on which you install BMC Performance Manager Express for EMC Disk Arrays shouldalready have

1 BMC Performance Manager Portal version 2500

2 Access to an RSM ie Remote Service Monitor

The RSM program must be installed on a Windows platform This can either be same as the serverwhere the Portal is installed or any other Windows computer on the network

Once you install BMC Performance Manager Express for EMC Disk Arrays you can add as manyelements as you require in your monitoring environment

Enabling the statistics

On EMC Clariion and VNX storage systems the statistics need to be enabled to allow BMCPerformance Manager Express for EMC Disk Arrays to collect statistics and to monitor performance

Using Navisphere

1 In Navisphere enable Statistics logging

middot Open Navisphere

middot Right-click the icon for the storage system

middot Click Properties

middot Be sure SP A and SP B are in the Storage Processors section

middot Click the box for Statistics Logging under the Configuration section

2 For locally attached CLARiiONs check if authorization info is present

3 Run the dv command from EMC TestSMIProvider Make sure all arrays are discovered withoutany errors

4 Make sure performance is turned on in the Profile for storage arrays

5 Make sure there are instances for the CIM_BlockStorageStatisticalData class

middot Run Tek-Tools testProvider or EMCrsquos testSMIProvider

middot Type ein for command

middot Type CIM_BlockStorageStatisticalData for Class Name

middot If no instances are returned reset EMC Provider

6 Once complete resume steps 1-3

If you are using a version older than SMIKit 642 the EMC SMI-S Provider does not recognize changes in the arraywhen a LUN or RAID Group is created or deleted from Navisphere It is thus recommended to upgrade your EMC SMI-SProvider to version 642 or higher to benefit from the auto-synchronization mechanism set by default to one hour afterthe last update If you do not upgrade your EMC SMI-S Provider you will have to run the refsys command fromtestsmiprovider each time you create or delete LUN or RAID groups from Navisphere

Managing Baselines and KeyPerformance IndicatorsIn order to facilitate the detection of abnormalities on your monitored environment BMCProactiveNet calculates baselines per parameter (metrics or attributes) based on values collectedover a specified period of time to determine a normal operating range When the collected values forthese parameters are out of range an alert is triggered

Some parameters are identified by default as Key Performance Indicators and therefore automaticallyincluded in the base lining calculation

42Managing Baselines and Key PerformanceIndicators

BMC Performance Manager Express for EMC Disk Arrays

Version 2001

Managing baselines

The baseline is the expected normal operating range for a metric or attribute of a monitor

The baseline is calculated by collecting the values for a monitorrsquos attributes and metrics over aspecified time period and establishing a low baseline value (consisting of the 10th percentile of all thevalues for a given time period) and a high baseline value (consisting of the 90th percentile of all thevalues for a given time period) taking a weighted average of these values over time A higher weightis given to the latest data being factored into the baseline average The accuracy of the baselineimproves over time

Requirements for baseline generation

For baselines to be generated for an attribute that abnormality threshold means that the thresholdexists and is not suppressed Additionally if the Key Performance Indicator (KPI) mode is active only those attributes that have anactive abnormality threshold and are also KPI attributes will have baselines generated for them

Absolute thresholds (with outside baseline) or signature thresholds do not satisfy these requirements

Managing Key Performance Indicators

The KPI attribute of a parameter can be activated or deactivated manually through the BMCProactiveNet Administration Console In this PM some parameters or attributes have beendesignated as important indicators of performance (KPIs) We do not recommend that these defaultsettings are modified

However advanced users may activate or deactivate KPIs from the BMC ProactiveNet AdministrationConsole

To add or remove Key Performance Indicator (KPI) attributes for amonitor type

1 In the Administration Console from the menu bar choose Tools gt KPI AdministrationThe KPI Administration dialog box is displayed

2 From the Monitor Type list choose the monitor type for which you want to add or remove KPIattributes A list of attributes for the selected monitor type is displayed

3 In the KPI column for the attributes that you want to add or remove as Key PerformanceIndicators

middot select the KPI check box to add the corresponding attribute as a KPI

middot deselect the KPI check box to remove the corresponding attribute from the KPIs for thatmonitor type

For complete and detailed information on this procedure please refer to the BMC ProactiveNet documentation availablefrom BMC Web site

This chapter explains how to use each monitoring tool ie a separate application class within theBMC Performance Manager Express for EMC Disk Arrays by Sentry Software solution

BMC Performance Manager Express for EMC Disk Arrays is a Performance Manager specifically designedfor BMC Portal consequently it uses the same common features and procedures of BMCreg Portal Thisdocument assumes that the user knows how to use the Portal and therefore explains procedures onlyrelated to BMC Performance Manager Express for EMC Disk Arrays and not on how to add ElementsElement Profiles etc Please refer to the BMC Portal documentation for details on how to use the Portal

Checking Available Spare Disks

To avoid any loss of critical data it is essential for a disk array to always maintain a pool of sparedisks that can replace the faulty disk when a disk failure occurs A disk array without any left sparedisk will not be able to keep the level of data safety and performance in case of a disk failure

The Spare Disk Count parameter of the SEN_EMC_ARRAY class reports the number of spare disksavailable for each disk array monitored with the solution By default a warning is triggered when nospare disk is available (Spare Disk Count is set to zero)

Verifying the Number of Available Spare Disks in Your EMC Disk Arrays

49Checking Available Spare Disks

BMC Performance Manager Express for EMC Disk Arrays

Version 2001

1 Select an element group in the tree view (the main Infrastructure group for example)

2 Click the Reports tab Create a report for the last 24 hours bottom 50 values of the Array|Spare Disk Count parameter of the EMC Disk Arrays application class for the BMC PerformanceManager Express for EMC Disk Arrays by Sentry Software solution

Detecting OversubscriptionSituations (Thin Provisioning)We call an oversubscription situation when

1 The storage pool is configured for thin provisioning (ldquothin storage poolrdquo)

2 The storage pool is oversubscribed ie the total disk space visible to the hosts (subscribers) isgreater than its actual capacity (this situation is normal for a thin pool since it is its very purpose)

3 The storage pool actual consumed capacity is nearing 100

Such situation is highly critical because the inability to allocate additional space to a LUN whenrequested by the subscriber host will lead to catastrophic data loss and corruption

When the conditions described above are met the solution sets the Oversubscription Situationparameter to 1 automatically raising a warning By default the warning for OversubscriptionSituation is issued when the Consumed Capacity Percentage parameter goes above 100 Thisthreshold can be configured in the input properties of the solution

50Detecting Oversubscription Situations (ThinProvisioning)

BMC Performance Manager Express for EMC Disk Arrays

Version 2001

Configuring Oversubscription Threshold

1 Click the EMC Disk Arrays icon and then the Configure tab

2 Edit the Oversubscription Situation Threshold () property to the appropriate value Whenthe Oversubscription Situation parameter triggers a warning it is highly recommended thatthe SAN administrators add capacity to the storage pool as soon as possible

Diagnosing Slow LUNs

If a system administrator complains that his servers are experiencing slow IOs performance and thatit is caused by the SAN you may want to verify the actual response time of the LUNs the server isrelying on

The Response Time parameter of the SEN_EMC_VOLUME class represents the average time it tookto complete the read and write operations on the LUN during the collection interval Typically theaverage response time is below 10 milliseconds You may also want to compare this value to theresponse time of the other LUNs to see whether one server is really getting worse IO performancethan another

Volume - Response Time Parameter

If the response time is low you will need to check the amount of data that is written and read onthis LUN The bad performance may simply be due to an abnormally large amount of data to processOtherwise the problem is maybe between the disk array and the server in the fiber links

51Enabling the Debug Mode

BMC Performance Manager Express for EMC Disk Arrays

Version 2001

Enabling the Debug Mode

By default BMC Performance Manager Express for EMC Disk Arrays sends only the most criticalinformation warning and error messages to the Application Collection Status parameter Mostoften this information is accurate enough to ensure that BMC Performance Manager Express for EMCDisk Arrays is functioning properly If you encounter an issue and wish to report it to customersupport you will be asked to enable the Debug Mode and provide the debug output to the supportteam

1 In the Configure tab gt under Tasks click Elements

2 Select the Element whose debug output you require and click Edit

3 Scroll down to Application Classes gt click the Application class for which you want toenable the debug mode gt click Edit

4 Select Yes from the drop-down Debug Mode list gt SaveBy default BMC Performance Manager Express for EMC Disk Arrays sends its debug output to RSM_HOMERSM(xx)serverrsmlogsen_debuglog

5 Wait for 15 minutes and then disable the debug mode by selecting No

6 Send the debug file to the support team

Pay attention to the file size -the debug output of BMC Performance Manager Express for EMC Disk Arrays could bevery large if enabled for several days

Identifying the Hosts that canAccess a LUNIn most SAN configurations each LUN belongs to a storage group whose host members are the onlyones authorized to access the LUN This is called LUN masking For each LUN the solution displaysits WWN the storage group to which it belongs to as well as the hosts member of this group Inmost cases identifying the storage group of a LUN is sufficient to recognize the server that is usingit

52Identifying LUNs not Owned by their Normal(Default) Storage Processor

BMC Performance Manager Express for EMC Disk Arrays

Version 2001

Identifying LUNs not Owned bytheir Normal (Default) StorageProcessorThe Owning Storage Processor parameter reports the name of the controller that handles IOsfor each LUN If a LUN is not currently handled by its normal (default) storage processors the nameof the default controller will be indicated as SP_B (default SP_A)rdquo

To identify LUNs that are not owned by their normal storage processor you simply need to list the Volume objects where the Owning Storage Processor parameter contains the string Default

Identifying Most Busy LUNs

To identify the LUNs that generate the most traffic on the disk array use the Read Byte Rate andWrite Byte Rate parameters of the LUN class that expose the data throughput for each LUN Usethese parameters to report on the total data traffic (per hour or per day) on each LUN in GB

To make sure that traffic is displayed cumulatively per hour select a time window of at least 12 hours in the graphwindow select at least 7 days to visualize per day cumulative data

1 In the Status tab click the Volume for which you need to check the LUNs activity then expandthe LUNs object to display the ReadWrite Byte Rate parameters

53Identifying Most Busy LUNs

54Identifying Most Busy LUNs

BMC Performance Manager Express for EMC Disk Arrays

Version 2001

View ing a LUNs ReadW rite Byte Rate as a graph

Identifying a Storage Processor(Controllers) OverloadTo visualize the activity of a controller in an EMC disk array use the Processor Utilizationparameter of the SEN_EMC_CONTROLLER class A warning is issued when the processor utilizationgoes too high which means that the controllers cannot keep up with the load on the disk array It isthen important to identify what is overloading the controllers

The Response Time parameter of the SEN_EMC_CONTROLLER class represents the average time ittook the controller to process the read and write requests of the hosts The higher the ResponseTime goes the slower IOs the servers will get By default the solution triggers a warning when thecontroller takes more than 10 milliseconds on average to complete the IO requests and an alarmwhen the response time reaches 100 milliseconds

Monitoring the Efficiency of theCaching MechanismEach controller in an EMC disk array can be configured to use a specified amount of memory tocache the read andor write operations The solution reports the amount of memory configured byeach controller for the read and write operations

The Write Flush Byte Rate represents the rate in MBsec at which data is committed to the disk(ie physically written) This value is to be compared with the Write Byte Rate of the disk array

55Monitoring the Efficiency of the CachingMechanism

BMC Performance Manager Express for EMC Disk Arrays

Version 2001

Comparing W rite Flush Byte Rate w ith W rite Byte Rate

The Cache Dirty Pages Percentage parameter represents the amount in percentage of the writecache that has been modified by host write operations and not yet flushed to the disks Reaching100 means that write case is too small and cannot handle the flow of write operations

Checking the Cache Dirty Pages Percentage

Reclaiming Space of Unmapped(Unused) LUNsOver time as servers connected to a SAN get decommissioned administrators find an increasingnumber of unmapped LUNs or volumes that are no longer used by any server These LUNs whileunused still occupy disk space in the disk array Being able to identify such unmapped LUNs andreclaim the disk space uselessly consumed by these LUNs will help administrators avoid unnecessaryupgrades and extensions of their disk arrays

56Reporting a Disk Space Consumption

BMC Performance Manager Express for EMC Disk Arrays

Version 2001

Reporting a Disk SpaceConsumptionMaking sure that a disk array has enough remaining disk space available is critical for severalreasons

middot SAN administrators want to make sure to be able to provision disk space for new servers whenrequested as quickly as possible

middot The disk array itself may need additional disk space for specific features to work properly likeautomatic snapshots mirroring etc

middot If thin provisioning is used the remaining disk space becomes dramatically critical since theinability to allocate additional space to a LUN when requested by the subscriber host will lead tocatastrophic data loss and corruption

The disk space used is permanently monitored for each storage pool The Subscribed Capacityparameter of the Pool class represents the amount of disk space that has been made available tothe subscriber hosts or in other words the amount of disk space that is seen by the serversconnected to disk array

The Consumed Capacity parameter of the SEN_EMC_STORAGEPOOLS class represents the actualspace usage in the storage pool For thin pools (when thin provisioning is enabled on the disk array)this value is normally lower than the Subscribed Capacity as it is the main purpose of thinprovisioning For traditional pools the Consumed Capacity parameters has the same value as theSubscribed Capacity parameter as the entirety of the subscribed disk space is fully allocated inthe storage pool

The Consumed Capacity Percentage parameter is the most critical one as a storage pool usagenearing 100 means that SAN administrators will not be able to create new LUNs in the storagepool By default no alarm or warning threshold is set on this parameter as the fullness of a storagepool may be a normal situation However you can set alert thresholds on this parameter as it fitsyour needs

57Reporting a Disk Space Consumption

2 Click on the Reports tab

3 Create a report for the last 24 hours top 50 values of the Array|Storage Pools|Disk Group|Storage Pool|Consumed Capacity Percentage parameter of the EMC Disk Arraysapplication class for the BMC Performance Manager Express for EMC Disk Arrays by SentrySoftware solution

Report ndash Disk Space Consumption

Reporting the Total Traffic on anHourly or Daily BasisBMC Performance Manager Express for EMC Disk Arrays not only monitors the traffic and activity ofthe disk array controllers LUNs and physical disks in MBsec but also in GB per hour or per day Theexact amount of data that was read or written to the disk array LUN or physical disk is calculated foreach hour of the day and each day of the week

Each data rate parameter in MBsec is accompanied by a non-rate one in GB These parameters areldquocumulativerdquo their instantaneous value has no meaning and they need to be visualized in a longperiod of time (instead of Read Byte Rate or Write Byte Rate)

Setting thresholds

Whenever relevant BMC Performance Manager Express for EMC Disk Arrays automatically setsthresholds for parameters If you prefer a more fault-tolerant monitoring you can modify thethresholds of each parameter through the Configure tab gt Edit Thresholds

It is strongly recommended to wait for all the storage objects to be discovered before setting threshold values to avoidhaving to enter thresholds for each occurrence of the application class

To modify the parameter thresholds of several storage objects of an element

60Setting thresholds

BMC Performance Manager Express for EMC Disk Arrays

Version 2001

1 In the Configure tab click on the Storage (ltplatformgt) or the instance icon gt Edit

Thresholds Properties and Credentials

Any modification to the thresholds or any other properties of elements created using the Element

Profile mode is to be done using the Element Profile route or by clicking Override Profile

2 Uncheck the Warning and Alarm boxes for all the parameters for which you want to disablethe alert conditions

BMC Performance Manager Express for EMC Disk Arrays

Version 2001

BMC Performance Manager Express for EMC Disk Arrays is an agent-less Performance Manager forthe BMC Portal environment It allows you to automatically discover and monitor every aspect of EMCdisk arrays from the general health of the array to the performance of the LUNs and from the filesystems space usage to the mirroring and snapshots mechanisms latency and to consolidate diversemonitoring needs within the Portal framework through a single solution

To setup a complete monitoring of the disk array we strongly recommend you to also use BMCPerformance Manager Express for Hardware that covers all the physical aspect of the disk array (statusof the disks ports temperature power supplies power consumption etc)

Being a Performance Manager specifically designed for BMC Portal BMC Performance ManagerExpress for EMC Disk Arrays uses the Portalrsquos web-based interface and features for installingmanaging and monitoring your infrastructure

Getting Started

11

BMC Performance Manager Express for EMC Disk Arrays

Version 2001

This chapter describes the prerequisites and the procedures you must perform before installing BMCPerformance Manager Express for EMC Disk Arrays Please follow the given instructions carefully inorder to ensure a successful integration of the solution within the Portal environment

Minimum Requirements

The computer on which you install BMC Performance Manager Express for EMC Disk Arrays shouldalready have

1 BMC Performance Manager Portal version 2500

2 Access to an RSM ie Remote Service Monitor

The RSM program must be installed on a Windows platform This can either be same as the serverwhere the Portal is installed or any other Windows computer on the network

Once you install BMC Performance Manager Express for EMC Disk Arrays you can add as manyelements as you require in your monitoring environment

Enabling the statistics

On EMC Clariion and VNX storage systems the statistics need to be enabled to allow BMCPerformance Manager Express for EMC Disk Arrays to collect statistics and to monitor performance

Using Navisphere

1 In Navisphere enable Statistics logging

middot Open Navisphere

middot Right-click the icon for the storage system

middot Click Properties

middot Be sure SP A and SP B are in the Storage Processors section

middot Click the box for Statistics Logging under the Configuration section

2 For locally attached CLARiiONs check if authorization info is present

3 Run the dv command from EMC TestSMIProvider Make sure all arrays are discovered withoutany errors

4 Make sure performance is turned on in the Profile for storage arrays

5 Make sure there are instances for the CIM_BlockStorageStatisticalData class

middot Run Tek-Tools testProvider or EMCrsquos testSMIProvider

middot Type ein for command

middot Type CIM_BlockStorageStatisticalData for Class Name

middot If no instances are returned reset EMC Provider

6 Once complete resume steps 1-3

If you are using a version older than SMIKit 642 the EMC SMI-S Provider does not recognize changes in the arraywhen a LUN or RAID Group is created or deleted from Navisphere It is thus recommended to upgrade your EMC SMI-SProvider to version 642 or higher to benefit from the auto-synchronization mechanism set by default to one hour afterthe last update If you do not upgrade your EMC SMI-S Provider you will have to run the refsys command fromtestsmiprovider each time you create or delete LUN or RAID groups from Navisphere

Managing Baselines and KeyPerformance IndicatorsIn order to facilitate the detection of abnormalities on your monitored environment BMCProactiveNet calculates baselines per parameter (metrics or attributes) based on values collectedover a specified period of time to determine a normal operating range When the collected values forthese parameters are out of range an alert is triggered

Some parameters are identified by default as Key Performance Indicators and therefore automaticallyincluded in the base lining calculation

42Managing Baselines and Key PerformanceIndicators

BMC Performance Manager Express for EMC Disk Arrays

Version 2001

Managing baselines

The baseline is the expected normal operating range for a metric or attribute of a monitor

The baseline is calculated by collecting the values for a monitorrsquos attributes and metrics over aspecified time period and establishing a low baseline value (consisting of the 10th percentile of all thevalues for a given time period) and a high baseline value (consisting of the 90th percentile of all thevalues for a given time period) taking a weighted average of these values over time A higher weightis given to the latest data being factored into the baseline average The accuracy of the baselineimproves over time

Requirements for baseline generation

For baselines to be generated for an attribute that abnormality threshold means that the thresholdexists and is not suppressed Additionally if the Key Performance Indicator (KPI) mode is active only those attributes that have anactive abnormality threshold and are also KPI attributes will have baselines generated for them

Absolute thresholds (with outside baseline) or signature thresholds do not satisfy these requirements

Managing Key Performance Indicators

The KPI attribute of a parameter can be activated or deactivated manually through the BMCProactiveNet Administration Console In this PM some parameters or attributes have beendesignated as important indicators of performance (KPIs) We do not recommend that these defaultsettings are modified

However advanced users may activate or deactivate KPIs from the BMC ProactiveNet AdministrationConsole

To add or remove Key Performance Indicator (KPI) attributes for amonitor type

1 In the Administration Console from the menu bar choose Tools gt KPI AdministrationThe KPI Administration dialog box is displayed

2 From the Monitor Type list choose the monitor type for which you want to add or remove KPIattributes A list of attributes for the selected monitor type is displayed

3 In the KPI column for the attributes that you want to add or remove as Key PerformanceIndicators

middot select the KPI check box to add the corresponding attribute as a KPI

middot deselect the KPI check box to remove the corresponding attribute from the KPIs for thatmonitor type

For complete and detailed information on this procedure please refer to the BMC ProactiveNet documentation availablefrom BMC Web site

BMC Performance Manager Express for EMC Disk Arrays monitors all of the performance metrics andusage statistics of your EMC disk arrays such as file disk space usage storage controller utilizationIOs on the diskscontrollersvolumes etc It continuously monitors the activity of each array and isalso able to build reports on past utilization statistics

To setup a complete monitoring of the array we strongly recommend you to also use BMCPerformance Manager Express for Hardware that covers all the physical aspect of the EMC diskarrays (status of the disks ports temperature power supplies power consumption etc)

This chapter explains how to use each monitoring tool ie a separate application class within theBMC Performance Manager Express for EMC Disk Arrays by Sentry Software solution

BMC Performance Manager Express for EMC Disk Arrays is a Performance Manager specifically designedfor BMC Portal consequently it uses the same common features and procedures of BMCreg Portal Thisdocument assumes that the user knows how to use the Portal and therefore explains procedures onlyrelated to BMC Performance Manager Express for EMC Disk Arrays and not on how to add ElementsElement Profiles etc Please refer to the BMC Portal documentation for details on how to use the Portal

Checking Available Spare Disks

To avoid any loss of critical data it is essential for a disk array to always maintain a pool of sparedisks that can replace the faulty disk when a disk failure occurs A disk array without any left sparedisk will not be able to keep the level of data safety and performance in case of a disk failure

The Spare Disk Count parameter of the SEN_EMC_ARRAY class reports the number of spare disksavailable for each disk array monitored with the solution By default a warning is triggered when nospare disk is available (Spare Disk Count is set to zero)

Verifying the Number of Available Spare Disks in Your EMC Disk Arrays

49Checking Available Spare Disks

BMC Performance Manager Express for EMC Disk Arrays

Version 2001

1 Select an element group in the tree view (the main Infrastructure group for example)

2 Click the Reports tab Create a report for the last 24 hours bottom 50 values of the Array|Spare Disk Count parameter of the EMC Disk Arrays application class for the BMC PerformanceManager Express for EMC Disk Arrays by Sentry Software solution

Detecting OversubscriptionSituations (Thin Provisioning)We call an oversubscription situation when

1 The storage pool is configured for thin provisioning (ldquothin storage poolrdquo)

2 The storage pool is oversubscribed ie the total disk space visible to the hosts (subscribers) isgreater than its actual capacity (this situation is normal for a thin pool since it is its very purpose)

3 The storage pool actual consumed capacity is nearing 100

Such situation is highly critical because the inability to allocate additional space to a LUN whenrequested by the subscriber host will lead to catastrophic data loss and corruption

When the conditions described above are met the solution sets the Oversubscription Situationparameter to 1 automatically raising a warning By default the warning for OversubscriptionSituation is issued when the Consumed Capacity Percentage parameter goes above 100 Thisthreshold can be configured in the input properties of the solution

50Detecting Oversubscription Situations (ThinProvisioning)

BMC Performance Manager Express for EMC Disk Arrays

Version 2001

Configuring Oversubscription Threshold

1 Click the EMC Disk Arrays icon and then the Configure tab

2 Edit the Oversubscription Situation Threshold () property to the appropriate value Whenthe Oversubscription Situation parameter triggers a warning it is highly recommended thatthe SAN administrators add capacity to the storage pool as soon as possible

Diagnosing Slow LUNs

If a system administrator complains that his servers are experiencing slow IOs performance and thatit is caused by the SAN you may want to verify the actual response time of the LUNs the server isrelying on

The Response Time parameter of the SEN_EMC_VOLUME class represents the average time it tookto complete the read and write operations on the LUN during the collection interval Typically theaverage response time is below 10 milliseconds You may also want to compare this value to theresponse time of the other LUNs to see whether one server is really getting worse IO performancethan another

Volume - Response Time Parameter

If the response time is low you will need to check the amount of data that is written and read onthis LUN The bad performance may simply be due to an abnormally large amount of data to processOtherwise the problem is maybe between the disk array and the server in the fiber links

51Enabling the Debug Mode

BMC Performance Manager Express for EMC Disk Arrays

Version 2001

Enabling the Debug Mode

By default BMC Performance Manager Express for EMC Disk Arrays sends only the most criticalinformation warning and error messages to the Application Collection Status parameter Mostoften this information is accurate enough to ensure that BMC Performance Manager Express for EMCDisk Arrays is functioning properly If you encounter an issue and wish to report it to customersupport you will be asked to enable the Debug Mode and provide the debug output to the supportteam

1 In the Configure tab gt under Tasks click Elements

2 Select the Element whose debug output you require and click Edit

3 Scroll down to Application Classes gt click the Application class for which you want toenable the debug mode gt click Edit

4 Select Yes from the drop-down Debug Mode list gt SaveBy default BMC Performance Manager Express for EMC Disk Arrays sends its debug output to RSM_HOMERSM(xx)serverrsmlogsen_debuglog

5 Wait for 15 minutes and then disable the debug mode by selecting No

6 Send the debug file to the support team

Pay attention to the file size -the debug output of BMC Performance Manager Express for EMC Disk Arrays could bevery large if enabled for several days

Identifying the Hosts that canAccess a LUNIn most SAN configurations each LUN belongs to a storage group whose host members are the onlyones authorized to access the LUN This is called LUN masking For each LUN the solution displaysits WWN the storage group to which it belongs to as well as the hosts member of this group Inmost cases identifying the storage group of a LUN is sufficient to recognize the server that is usingit

52Identifying LUNs not Owned by their Normal(Default) Storage Processor

BMC Performance Manager Express for EMC Disk Arrays

Version 2001

Identifying LUNs not Owned bytheir Normal (Default) StorageProcessorThe Owning Storage Processor parameter reports the name of the controller that handles IOsfor each LUN If a LUN is not currently handled by its normal (default) storage processors the nameof the default controller will be indicated as SP_B (default SP_A)rdquo

To identify LUNs that are not owned by their normal storage processor you simply need to list the Volume objects where the Owning Storage Processor parameter contains the string Default

Identifying Most Busy LUNs

To identify the LUNs that generate the most traffic on the disk array use the Read Byte Rate andWrite Byte Rate parameters of the LUN class that expose the data throughput for each LUN Usethese parameters to report on the total data traffic (per hour or per day) on each LUN in GB

To make sure that traffic is displayed cumulatively per hour select a time window of at least 12 hours in the graphwindow select at least 7 days to visualize per day cumulative data

1 In the Status tab click the Volume for which you need to check the LUNs activity then expandthe LUNs object to display the ReadWrite Byte Rate parameters

53Identifying Most Busy LUNs

2 Click the History icon to automatically display a graph that shows the ReadWrite Byte Ratevalues collected for a selected parameter during the previous six hours You can customize thechart and table to show parameter history for different time periods

54Identifying Most Busy LUNs

BMC Performance Manager Express for EMC Disk Arrays

Version 2001

View ing a LUNs ReadW rite Byte Rate as a graph

Identifying a Storage Processor(Controllers) OverloadTo visualize the activity of a controller in an EMC disk array use the Processor Utilizationparameter of the SEN_EMC_CONTROLLER class A warning is issued when the processor utilizationgoes too high which means that the controllers cannot keep up with the load on the disk array It isthen important to identify what is overloading the controllers

The Response Time parameter of the SEN_EMC_CONTROLLER class represents the average time ittook the controller to process the read and write requests of the hosts The higher the ResponseTime goes the slower IOs the servers will get By default the solution triggers a warning when thecontroller takes more than 10 milliseconds on average to complete the IO requests and an alarmwhen the response time reaches 100 milliseconds

Monitoring the Efficiency of theCaching MechanismEach controller in an EMC disk array can be configured to use a specified amount of memory tocache the read andor write operations The solution reports the amount of memory configured byeach controller for the read and write operations

The Write Flush Byte Rate represents the rate in MBsec at which data is committed to the disk(ie physically written) This value is to be compared with the Write Byte Rate of the disk array

55Monitoring the Efficiency of the CachingMechanism

BMC Performance Manager Express for EMC Disk Arrays

Version 2001

Comparing W rite Flush Byte Rate w ith W rite Byte Rate

The Cache Dirty Pages Percentage parameter represents the amount in percentage of the writecache that has been modified by host write operations and not yet flushed to the disks Reaching100 means that write case is too small and cannot handle the flow of write operations

Checking the Cache Dirty Pages Percentage

Reclaiming Space of Unmapped(Unused) LUNsOver time as servers connected to a SAN get decommissioned administrators find an increasingnumber of unmapped LUNs or volumes that are no longer used by any server These LUNs whileunused still occupy disk space in the disk array Being able to identify such unmapped LUNs andreclaim the disk space uselessly consumed by these LUNs will help administrators avoid unnecessaryupgrades and extensions of their disk arrays

56Reporting a Disk Space Consumption

BMC Performance Manager Express for EMC Disk Arrays

Version 2001

Reporting a Disk SpaceConsumptionMaking sure that a disk array has enough remaining disk space available is critical for severalreasons

middot SAN administrators want to make sure to be able to provision disk space for new servers whenrequested as quickly as possible

middot The disk array itself may need additional disk space for specific features to work properly likeautomatic snapshots mirroring etc

middot If thin provisioning is used the remaining disk space becomes dramatically critical since theinability to allocate additional space to a LUN when requested by the subscriber host will lead tocatastrophic data loss and corruption

The disk space used is permanently monitored for each storage pool The Subscribed Capacityparameter of the Pool class represents the amount of disk space that has been made available tothe subscriber hosts or in other words the amount of disk space that is seen by the serversconnected to disk array

The Consumed Capacity parameter of the SEN_EMC_STORAGEPOOLS class represents the actualspace usage in the storage pool For thin pools (when thin provisioning is enabled on the disk array)this value is normally lower than the Subscribed Capacity as it is the main purpose of thinprovisioning For traditional pools the Consumed Capacity parameters has the same value as theSubscribed Capacity parameter as the entirety of the subscribed disk space is fully allocated inthe storage pool

The Consumed Capacity Percentage parameter is the most critical one as a storage pool usagenearing 100 means that SAN administrators will not be able to create new LUNs in the storagepool By default no alarm or warning threshold is set on this parameter as the fullness of a storagepool may be a normal situation However you can set alert thresholds on this parameter as it fitsyour needs

57Reporting a Disk Space Consumption

BMC Performance Manager Express for EMC Disk Arrays

Version 2001

Verifying the Available Disk Space in the Storage Pool of your EMC DiskArrays

1 In the Configure tab select an element group in the tree view (the main ldquoInfrastructurerdquogroup for example)

2 Click on the Reports tab

3 Create a report for the last 24 hours top 50 values of the Array|Storage Pools|Disk Group|Storage Pool|Consumed Capacity Percentage parameter of the EMC Disk Arraysapplication class for the BMC Performance Manager Express for EMC Disk Arrays by SentrySoftware solution

Report ndash Disk Space Consumption

Reporting the Total Traffic on anHourly or Daily BasisBMC Performance Manager Express for EMC Disk Arrays not only monitors the traffic and activity ofthe disk array controllers LUNs and physical disks in MBsec but also in GB per hour or per day Theexact amount of data that was read or written to the disk array LUN or physical disk is calculated foreach hour of the day and each day of the week

Each data rate parameter in MBsec is accompanied by a non-rate one in GB These parameters areldquocumulativerdquo their instantaneous value has no meaning and they need to be visualized in a longperiod of time (instead of Read Byte Rate or Write Byte Rate)

58Reporting the Total Traffic on an Hourly orDaily Basis

Setting thresholds

Whenever relevant BMC Performance Manager Express for EMC Disk Arrays automatically setsthresholds for parameters If you prefer a more fault-tolerant monitoring you can modify thethresholds of each parameter through the Configure tab gt Edit Thresholds

It is strongly recommended to wait for all the storage objects to be discovered before setting threshold values to avoidhaving to enter thresholds for each occurrence of the application class

To modify the parameter thresholds of several storage objects of an element

60Setting thresholds

BMC Performance Manager Express for EMC Disk Arrays

Version 2001

1 In the Configure tab click on the Storage (ltplatformgt) or the instance icon gt Edit

Thresholds Properties and Credentials

Any modification to the thresholds or any other properties of elements created using the Element

Profile mode is to be done using the Element Profile route or by clicking Override Profile

2 Uncheck the Warning and Alarm boxes for all the parameters for which you want to disablethe alert conditions

3 Check the Warning and Alarm boxes for all the parameters for which you want to enable thealert conditions You will then have to manually enter the threshold values and check the Activebox In the example below a Warning will be triggered if Status is greater than 1 an alarm willbe triggered when greater than 2

Modifying threshold values

4 Click Save

5 The Success changes have been saved message indicates that the modifications have beenregistered

Alerts are displayed by the parameter whose thresholds are modified

Viewing the Overall Activity of aDisk ArrayIn order to visualize the activity of a disk array use the Read Byte Rate and Write Byte Rate ofthe SEN_EMC_ARRAY class These parameters represent the overall traffic in megabytes per secondfor each monitored array or more precisely each EMC disk array that is exposed through the EMCSMI-S Provider (see the EMC_SMI-S_Provider section of the Installation Guide for more informationabout the EMC SMI-S Provider)

62Viewing the Overall Activity of a Disk Array

BMC Performance Manager Express for EMC Disk Arrays

middot Right-click the icon for the storage system

middot Click Properties

middot Be sure SP A and SP B are in the Storage Processors section

middot Click the box for Statistics Logging under the Configuration section

2 For locally attached CLARiiONs check if authorization info is present

3 Run the dv command from EMC TestSMIProvider Make sure all arrays are discovered withoutany errors

4 Make sure performance is turned on in the Profile for storage arrays

5 Make sure there are instances for the CIM_BlockStorageStatisticalData class

middot Run Tek-Tools testProvider or EMCrsquos testSMIProvider

middot Type ein for command

middot Type CIM_BlockStorageStatisticalData for Class Name

middot If no instances are returned reset EMC Provider

6 Once complete resume steps 1-3

If you are using a version older than SMIKit 642 the EMC SMI-S Provider does not recognize changes in the arraywhen a LUN or RAID Group is created or deleted from Navisphere It is thus recommended to upgrade your EMC SMI-SProvider to version 642 or higher to benefit from the auto-synchronization mechanism set by default to one hour afterthe last update If you do not upgrade your EMC SMI-S Provider you will have to run the refsys command fromtestsmiprovider each time you create or delete LUN or RAID groups from Navisphere

Managing Baselines and KeyPerformance IndicatorsIn order to facilitate the detection of abnormalities on your monitored environment BMCProactiveNet calculates baselines per parameter (metrics or attributes) based on values collectedover a specified period of time to determine a normal operating range When the collected values forthese parameters are out of range an alert is triggered

Some parameters are identified by default as Key Performance Indicators and therefore automaticallyincluded in the base lining calculation

42Managing Baselines and Key PerformanceIndicators

BMC Performance Manager Express for EMC Disk Arrays

Version 2001

Managing baselines

The baseline is the expected normal operating range for a metric or attribute of a monitor

The baseline is calculated by collecting the values for a monitorrsquos attributes and metrics over aspecified time period and establishing a low baseline value (consisting of the 10th percentile of all thevalues for a given time period) and a high baseline value (consisting of the 90th percentile of all thevalues for a given time period) taking a weighted average of these values over time A higher weightis given to the latest data being factored into the baseline average The accuracy of the baselineimproves over time

Requirements for baseline generation

For baselines to be generated for an attribute that abnormality threshold means that the thresholdexists and is not suppressed Additionally if the Key Performance Indicator (KPI) mode is active only those attributes that have anactive abnormality threshold and are also KPI attributes will have baselines generated for them

Absolute thresholds (with outside baseline) or signature thresholds do not satisfy these requirements

Managing Key Performance Indicators

The KPI attribute of a parameter can be activated or deactivated manually through the BMCProactiveNet Administration Console In this PM some parameters or attributes have beendesignated as important indicators of performance (KPIs) We do not recommend that these defaultsettings are modified

However advanced users may activate or deactivate KPIs from the BMC ProactiveNet AdministrationConsole

To add or remove Key Performance Indicator (KPI) attributes for amonitor type

1 In the Administration Console from the menu bar choose Tools gt KPI AdministrationThe KPI Administration dialog box is displayed

2 From the Monitor Type list choose the monitor type for which you want to add or remove KPIattributes A list of attributes for the selected monitor type is displayed

3 In the KPI column for the attributes that you want to add or remove as Key PerformanceIndicators

middot select the KPI check box to add the corresponding attribute as a KPI

middot deselect the KPI check box to remove the corresponding attribute from the KPIs for thatmonitor type

For complete and detailed information on this procedure please refer to the BMC ProactiveNet documentation availablefrom BMC Web site

BMC Performance Manager Express for EMC Disk Arrays

Version 2001

BMC Performance Manager Express for EMC Disk Arrays monitors all of the performance metrics andusage statistics of your EMC disk arrays such as file disk space usage storage controller utilizationIOs on the diskscontrollersvolumes etc It continuously monitors the activity of each array and isalso able to build reports on past utilization statistics

To setup a complete monitoring of the array we strongly recommend you to also use BMCPerformance Manager Express for Hardware that covers all the physical aspect of the EMC diskarrays (status of the disks ports temperature power supplies power consumption etc)

This chapter explains how to use each monitoring tool ie a separate application class within theBMC Performance Manager Express for EMC Disk Arrays by Sentry Software solution

BMC Performance Manager Express for EMC Disk Arrays is a Performance Manager specifically designedfor BMC Portal consequently it uses the same common features and procedures of BMCreg Portal Thisdocument assumes that the user knows how to use the Portal and therefore explains procedures onlyrelated to BMC Performance Manager Express for EMC Disk Arrays and not on how to add ElementsElement Profiles etc Please refer to the BMC Portal documentation for details on how to use the Portal

Checking Available Spare Disks

To avoid any loss of critical data it is essential for a disk array to always maintain a pool of sparedisks that can replace the faulty disk when a disk failure occurs A disk array without any left sparedisk will not be able to keep the level of data safety and performance in case of a disk failure

The Spare Disk Count parameter of the SEN_EMC_ARRAY class reports the number of spare disksavailable for each disk array monitored with the solution By default a warning is triggered when nospare disk is available (Spare Disk Count is set to zero)

Verifying the Number of Available Spare Disks in Your EMC Disk Arrays

49Checking Available Spare Disks

BMC Performance Manager Express for EMC Disk Arrays

Version 2001

1 Select an element group in the tree view (the main Infrastructure group for example)

2 Click the Reports tab Create a report for the last 24 hours bottom 50 values of the Array|Spare Disk Count parameter of the EMC Disk Arrays application class for the BMC PerformanceManager Express for EMC Disk Arrays by Sentry Software solution

Report ndash Available Spare Disks

Detecting OversubscriptionSituations (Thin Provisioning)We call an oversubscription situation when

1 The storage pool is configured for thin provisioning (ldquothin storage poolrdquo)

2 The storage pool is oversubscribed ie the total disk space visible to the hosts (subscribers) isgreater than its actual capacity (this situation is normal for a thin pool since it is its very purpose)

3 The storage pool actual consumed capacity is nearing 100

Such situation is highly critical because the inability to allocate additional space to a LUN whenrequested by the subscriber host will lead to catastrophic data loss and corruption

When the conditions described above are met the solution sets the Oversubscription Situationparameter to 1 automatically raising a warning By default the warning for OversubscriptionSituation is issued when the Consumed Capacity Percentage parameter goes above 100 Thisthreshold can be configured in the input properties of the solution

50Detecting Oversubscription Situations (ThinProvisioning)

BMC Performance Manager Express for EMC Disk Arrays

Version 2001

Configuring Oversubscription Threshold

1 Click the EMC Disk Arrays icon and then the Configure tab

2 Edit the Oversubscription Situation Threshold () property to the appropriate value Whenthe Oversubscription Situation parameter triggers a warning it is highly recommended thatthe SAN administrators add capacity to the storage pool as soon as possible

Diagnosing Slow LUNs

If a system administrator complains that his servers are experiencing slow IOs performance and thatit is caused by the SAN you may want to verify the actual response time of the LUNs the server isrelying on

The Response Time parameter of the SEN_EMC_VOLUME class represents the average time it tookto complete the read and write operations on the LUN during the collection interval Typically theaverage response time is below 10 milliseconds You may also want to compare this value to theresponse time of the other LUNs to see whether one server is really getting worse IO performancethan another

Volume - Response Time Parameter

If the response time is low you will need to check the amount of data that is written and read onthis LUN The bad performance may simply be due to an abnormally large amount of data to processOtherwise the problem is maybe between the disk array and the server in the fiber links

51Enabling the Debug Mode

BMC Performance Manager Express for EMC Disk Arrays

Version 2001

Enabling the Debug Mode

By default BMC Performance Manager Express for EMC Disk Arrays sends only the most criticalinformation warning and error messages to the Application Collection Status parameter Mostoften this information is accurate enough to ensure that BMC Performance Manager Express for EMCDisk Arrays is functioning properly If you encounter an issue and wish to report it to customersupport you will be asked to enable the Debug Mode and provide the debug output to the supportteam

1 In the Configure tab gt under Tasks click Elements

2 Select the Element whose debug output you require and click Edit

3 Scroll down to Application Classes gt click the Application class for which you want toenable the debug mode gt click Edit

4 Select Yes from the drop-down Debug Mode list gt SaveBy default BMC Performance Manager Express for EMC Disk Arrays sends its debug output to RSM_HOMERSM(xx)serverrsmlogsen_debuglog

5 Wait for 15 minutes and then disable the debug mode by selecting No

6 Send the debug file to the support team

Pay attention to the file size -the debug output of BMC Performance Manager Express for EMC Disk Arrays could bevery large if enabled for several days

Identifying the Hosts that canAccess a LUNIn most SAN configurations each LUN belongs to a storage group whose host members are the onlyones authorized to access the LUN This is called LUN masking For each LUN the solution displaysits WWN the storage group to which it belongs to as well as the hosts member of this group Inmost cases identifying the storage group of a LUN is sufficient to recognize the server that is usingit

52Identifying LUNs not Owned by their Normal(Default) Storage Processor

BMC Performance Manager Express for EMC Disk Arrays

Version 2001

Identifying LUNs not Owned bytheir Normal (Default) StorageProcessorThe Owning Storage Processor parameter reports the name of the controller that handles IOsfor each LUN If a LUN is not currently handled by its normal (default) storage processors the nameof the default controller will be indicated as SP_B (default SP_A)rdquo

To identify LUNs that are not owned by their normal storage processor you simply need to list the Volume objects where the Owning Storage Processor parameter contains the string Default

Identifying Most Busy LUNs

To identify the LUNs that generate the most traffic on the disk array use the Read Byte Rate andWrite Byte Rate parameters of the LUN class that expose the data throughput for each LUN Usethese parameters to report on the total data traffic (per hour or per day) on each LUN in GB

To make sure that traffic is displayed cumulatively per hour select a time window of at least 12 hours in the graphwindow select at least 7 days to visualize per day cumulative data

1 In the Status tab click the Volume for which you need to check the LUNs activity then expandthe LUNs object to display the ReadWrite Byte Rate parameters

53Identifying Most Busy LUNs

54Identifying Most Busy LUNs

BMC Performance Manager Express for EMC Disk Arrays

Version 2001

View ing a LUNs ReadW rite Byte Rate as a graph

Identifying a Storage Processor(Controllers) OverloadTo visualize the activity of a controller in an EMC disk array use the Processor Utilizationparameter of the SEN_EMC_CONTROLLER class A warning is issued when the processor utilizationgoes too high which means that the controllers cannot keep up with the load on the disk array It isthen important to identify what is overloading the controllers

The Response Time parameter of the SEN_EMC_CONTROLLER class represents the average time ittook the controller to process the read and write requests of the hosts The higher the ResponseTime goes the slower IOs the servers will get By default the solution triggers a warning when thecontroller takes more than 10 milliseconds on average to complete the IO requests and an alarmwhen the response time reaches 100 milliseconds

Monitoring the Efficiency of theCaching MechanismEach controller in an EMC disk array can be configured to use a specified amount of memory tocache the read andor write operations The solution reports the amount of memory configured byeach controller for the read and write operations

The Write Flush Byte Rate represents the rate in MBsec at which data is committed to the disk(ie physically written) This value is to be compared with the Write Byte Rate of the disk array

55Monitoring the Efficiency of the CachingMechanism

BMC Performance Manager Express for EMC Disk Arrays

Version 2001

Comparing W rite Flush Byte Rate w ith W rite Byte Rate

The Cache Dirty Pages Percentage parameter represents the amount in percentage of the writecache that has been modified by host write operations and not yet flushed to the disks Reaching100 means that write case is too small and cannot handle the flow of write operations

Checking the Cache Dirty Pages Percentage

Reclaiming Space of Unmapped(Unused) LUNsOver time as servers connected to a SAN get decommissioned administrators find an increasingnumber of unmapped LUNs or volumes that are no longer used by any server These LUNs whileunused still occupy disk space in the disk array Being able to identify such unmapped LUNs andreclaim the disk space uselessly consumed by these LUNs will help administrators avoid unnecessaryupgrades and extensions of their disk arrays

56Reporting a Disk Space Consumption

BMC Performance Manager Express for EMC Disk Arrays

Version 2001

Reporting a Disk SpaceConsumptionMaking sure that a disk array has enough remaining disk space available is critical for severalreasons

middot SAN administrators want to make sure to be able to provision disk space for new servers whenrequested as quickly as possible

middot The disk array itself may need additional disk space for specific features to work properly likeautomatic snapshots mirroring etc

middot If thin provisioning is used the remaining disk space becomes dramatically critical since theinability to allocate additional space to a LUN when requested by the subscriber host will lead tocatastrophic data loss and corruption

The disk space used is permanently monitored for each storage pool The Subscribed Capacityparameter of the Pool class represents the amount of disk space that has been made available tothe subscriber hosts or in other words the amount of disk space that is seen by the serversconnected to disk array

The Consumed Capacity parameter of the SEN_EMC_STORAGEPOOLS class represents the actualspace usage in the storage pool For thin pools (when thin provisioning is enabled on the disk array)this value is normally lower than the Subscribed Capacity as it is the main purpose of thinprovisioning For traditional pools the Consumed Capacity parameters has the same value as theSubscribed Capacity parameter as the entirety of the subscribed disk space is fully allocated inthe storage pool

The Consumed Capacity Percentage parameter is the most critical one as a storage pool usagenearing 100 means that SAN administrators will not be able to create new LUNs in the storagepool By default no alarm or warning threshold is set on this parameter as the fullness of a storagepool may be a normal situation However you can set alert thresholds on this parameter as it fitsyour needs

57Reporting a Disk Space Consumption

BMC Performance Manager Express for EMC Disk Arrays

Version 2001

Verifying the Available Disk Space in the Storage Pool of your EMC DiskArrays

1 In the Configure tab select an element group in the tree view (the main ldquoInfrastructurerdquogroup for example)

2 Click on the Reports tab

3 Create a report for the last 24 hours top 50 values of the Array|Storage Pools|Disk Group|Storage Pool|Consumed Capacity Percentage parameter of the EMC Disk Arraysapplication class for the BMC Performance Manager Express for EMC Disk Arrays by SentrySoftware solution

Report ndash Disk Space Consumption

Reporting the Total Traffic on anHourly or Daily BasisBMC Performance Manager Express for EMC Disk Arrays not only monitors the traffic and activity ofthe disk array controllers LUNs and physical disks in MBsec but also in GB per hour or per day Theexact amount of data that was read or written to the disk array LUN or physical disk is calculated foreach hour of the day and each day of the week

Each data rate parameter in MBsec is accompanied by a non-rate one in GB These parameters areldquocumulativerdquo their instantaneous value has no meaning and they need to be visualized in a longperiod of time (instead of Read Byte Rate or Write Byte Rate)

58Reporting the Total Traffic on an Hourly orDaily Basis

BMC Performance Manager Express for EMC Disk Arrays

Setting thresholds

Whenever relevant BMC Performance Manager Express for EMC Disk Arrays automatically setsthresholds for parameters If you prefer a more fault-tolerant monitoring you can modify thethresholds of each parameter through the Configure tab gt Edit Thresholds

It is strongly recommended to wait for all the storage objects to be discovered before setting threshold values to avoidhaving to enter thresholds for each occurrence of the application class

To modify the parameter thresholds of several storage objects of an element

60Setting thresholds

BMC Performance Manager Express for EMC Disk Arrays

Version 2001

1 In the Configure tab click on the Storage (ltplatformgt) or the instance icon gt Edit

Thresholds Properties and Credentials

Any modification to the thresholds or any other properties of elements created using the Element

Profile mode is to be done using the Element Profile route or by clicking Override Profile

2 Uncheck the Warning and Alarm boxes for all the parameters for which you want to disablethe alert conditions

Disabling the default alert thresholds

61Setting thresholds

BMC Performance Manager Express for EMC Disk Arrays

3 Check the Warning and Alarm boxes for all the parameters for which you want to enable thealert conditions You will then have to manually enter the threshold values and check the Activebox In the example below a Warning will be triggered if Status is greater than 1 an alarm willbe triggered when greater than 2

Modifying threshold values

4 Click Save

5 The Success changes have been saved message indicates that the modifications have beenregistered

Alerts are displayed by the parameter whose thresholds are modified

Viewing the Overall Activity of aDisk ArrayIn order to visualize the activity of a disk array use the Read Byte Rate and Write Byte Rate ofthe SEN_EMC_ARRAY class These parameters represent the overall traffic in megabytes per secondfor each monitored array or more precisely each EMC disk array that is exposed through the EMCSMI-S Provider (see the EMC_SMI-S_Provider section of the Installation Guide for more informationabout the EMC SMI-S Provider)

62Viewing the Overall Activity of a Disk Array

BMC Performance Manager Express for EMC Disk Arrays

Version 2001

Viewing a Disk Array Activity

1 Click the Status tab in Portal

2 Click the array icon in the tree view to visualize its current activity

Selecting a Disk Array Parameter

middot Open Navisphere

middot Right-click the icon for the storage system

middot Click Properties

middot Be sure SP A and SP B are in the Storage Processors section

middot Click the box for Statistics Logging under the Configuration section

2 For locally attached CLARiiONs check if authorization info is present

3 Run the dv command from EMC TestSMIProvider Make sure all arrays are discovered withoutany errors

4 Make sure performance is turned on in the Profile for storage arrays

5 Make sure there are instances for the CIM_BlockStorageStatisticalData class

middot Run Tek-Tools testProvider or EMCrsquos testSMIProvider

middot Type ein for command

middot Type CIM_BlockStorageStatisticalData for Class Name

middot If no instances are returned reset EMC Provider

6 Once complete resume steps 1-3

If you are using a version older than SMIKit 642 the EMC SMI-S Provider does not recognize changes in the arraywhen a LUN or RAID Group is created or deleted from Navisphere It is thus recommended to upgrade your EMC SMI-SProvider to version 642 or higher to benefit from the auto-synchronization mechanism set by default to one hour afterthe last update If you do not upgrade your EMC SMI-S Provider you will have to run the refsys command fromtestsmiprovider each time you create or delete LUN or RAID groups from Navisphere

Managing Baselines and KeyPerformance IndicatorsIn order to facilitate the detection of abnormalities on your monitored environment BMCProactiveNet calculates baselines per parameter (metrics or attributes) based on values collectedover a specified period of time to determine a normal operating range When the collected values forthese parameters are out of range an alert is triggered

Some parameters are identified by default as Key Performance Indicators and therefore automaticallyincluded in the base lining calculation

42Managing Baselines and Key PerformanceIndicators

BMC Performance Manager Express for EMC Disk Arrays

Version 2001

Managing baselines

The baseline is the expected normal operating range for a metric or attribute of a monitor

The baseline is calculated by collecting the values for a monitorrsquos attributes and metrics over aspecified time period and establishing a low baseline value (consisting of the 10th percentile of all thevalues for a given time period) and a high baseline value (consisting of the 90th percentile of all thevalues for a given time period) taking a weighted average of these values over time A higher weightis given to the latest data being factored into the baseline average The accuracy of the baselineimproves over time

Requirements for baseline generation

For baselines to be generated for an attribute that abnormality threshold means that the thresholdexists and is not suppressed Additionally if the Key Performance Indicator (KPI) mode is active only those attributes that have anactive abnormality threshold and are also KPI attributes will have baselines generated for them

Absolute thresholds (with outside baseline) or signature thresholds do not satisfy these requirements

Managing Key Performance Indicators

The KPI attribute of a parameter can be activated or deactivated manually through the BMCProactiveNet Administration Console In this PM some parameters or attributes have beendesignated as important indicators of performance (KPIs) We do not recommend that these defaultsettings are modified

However advanced users may activate or deactivate KPIs from the BMC ProactiveNet AdministrationConsole

To add or remove Key Performance Indicator (KPI) attributes for amonitor type

1 In the Administration Console from the menu bar choose Tools gt KPI AdministrationThe KPI Administration dialog box is displayed

2 From the Monitor Type list choose the monitor type for which you want to add or remove KPIattributes A list of attributes for the selected monitor type is displayed

3 In the KPI column for the attributes that you want to add or remove as Key PerformanceIndicators

middot select the KPI check box to add the corresponding attribute as a KPI

middot deselect the KPI check box to remove the corresponding attribute from the KPIs for thatmonitor type

For complete and detailed information on this procedure please refer to the BMC ProactiveNet documentation availablefrom BMC Web site

BMC Performance Manager Express for EMC Disk Arrays

Version 2001

BMC Performance Manager Express for EMC Disk Arrays monitors all of the performance metrics andusage statistics of your EMC disk arrays such as file disk space usage storage controller utilizationIOs on the diskscontrollersvolumes etc It continuously monitors the activity of each array and isalso able to build reports on past utilization statistics

To setup a complete monitoring of the array we strongly recommend you to also use BMCPerformance Manager Express for Hardware that covers all the physical aspect of the EMC diskarrays (status of the disks ports temperature power supplies power consumption etc)

This chapter explains how to use each monitoring tool ie a separate application class within theBMC Performance Manager Express for EMC Disk Arrays by Sentry Software solution

BMC Performance Manager Express for EMC Disk Arrays is a Performance Manager specifically designedfor BMC Portal consequently it uses the same common features and procedures of BMCreg Portal Thisdocument assumes that the user knows how to use the Portal and therefore explains procedures onlyrelated to BMC Performance Manager Express for EMC Disk Arrays and not on how to add ElementsElement Profiles etc Please refer to the BMC Portal documentation for details on how to use the Portal

Checking Available Spare Disks

To avoid any loss of critical data it is essential for a disk array to always maintain a pool of sparedisks that can replace the faulty disk when a disk failure occurs A disk array without any left sparedisk will not be able to keep the level of data safety and performance in case of a disk failure

The Spare Disk Count parameter of the SEN_EMC_ARRAY class reports the number of spare disksavailable for each disk array monitored with the solution By default a warning is triggered when nospare disk is available (Spare Disk Count is set to zero)

Verifying the Number of Available Spare Disks in Your EMC Disk Arrays

49Checking Available Spare Disks

BMC Performance Manager Express for EMC Disk Arrays

Version 2001

1 Select an element group in the tree view (the main Infrastructure group for example)

2 Click the Reports tab Create a report for the last 24 hours bottom 50 values of the Array|Spare Disk Count parameter of the EMC Disk Arrays application class for the BMC PerformanceManager Express for EMC Disk Arrays by Sentry Software solution

Report ndash Available Spare Disks

Detecting OversubscriptionSituations (Thin Provisioning)We call an oversubscription situation when

1 The storage pool is configured for thin provisioning (ldquothin storage poolrdquo)

2 The storage pool is oversubscribed ie the total disk space visible to the hosts (subscribers) isgreater than its actual capacity (this situation is normal for a thin pool since it is its very purpose)

3 The storage pool actual consumed capacity is nearing 100

Such situation is highly critical because the inability to allocate additional space to a LUN whenrequested by the subscriber host will lead to catastrophic data loss and corruption

When the conditions described above are met the solution sets the Oversubscription Situationparameter to 1 automatically raising a warning By default the warning for OversubscriptionSituation is issued when the Consumed Capacity Percentage parameter goes above 100 Thisthreshold can be configured in the input properties of the solution

50Detecting Oversubscription Situations (ThinProvisioning)

BMC Performance Manager Express for EMC Disk Arrays

Version 2001

Configuring Oversubscription Threshold

1 Click the EMC Disk Arrays icon and then the Configure tab

2 Edit the Oversubscription Situation Threshold () property to the appropriate value Whenthe Oversubscription Situation parameter triggers a warning it is highly recommended thatthe SAN administrators add capacity to the storage pool as soon as possible

Diagnosing Slow LUNs

If a system administrator complains that his servers are experiencing slow IOs performance and thatit is caused by the SAN you may want to verify the actual response time of the LUNs the server isrelying on

The Response Time parameter of the SEN_EMC_VOLUME class represents the average time it tookto complete the read and write operations on the LUN during the collection interval Typically theaverage response time is below 10 milliseconds You may also want to compare this value to theresponse time of the other LUNs to see whether one server is really getting worse IO performancethan another

Volume - Response Time Parameter

If the response time is low you will need to check the amount of data that is written and read onthis LUN The bad performance may simply be due to an abnormally large amount of data to processOtherwise the problem is maybe between the disk array and the server in the fiber links

51Enabling the Debug Mode

BMC Performance Manager Express for EMC Disk Arrays

Version 2001

Enabling the Debug Mode

By default BMC Performance Manager Express for EMC Disk Arrays sends only the most criticalinformation warning and error messages to the Application Collection Status parameter Mostoften this information is accurate enough to ensure that BMC Performance Manager Express for EMCDisk Arrays is functioning properly If you encounter an issue and wish to report it to customersupport you will be asked to enable the Debug Mode and provide the debug output to the supportteam

1 In the Configure tab gt under Tasks click Elements

2 Select the Element whose debug output you require and click Edit

3 Scroll down to Application Classes gt click the Application class for which you want toenable the debug mode gt click Edit

4 Select Yes from the drop-down Debug Mode list gt SaveBy default BMC Performance Manager Express for EMC Disk Arrays sends its debug output to RSM_HOMERSM(xx)serverrsmlogsen_debuglog

5 Wait for 15 minutes and then disable the debug mode by selecting No

6 Send the debug file to the support team

Pay attention to the file size -the debug output of BMC Performance Manager Express for EMC Disk Arrays could bevery large if enabled for several days

Identifying the Hosts that canAccess a LUNIn most SAN configurations each LUN belongs to a storage group whose host members are the onlyones authorized to access the LUN This is called LUN masking For each LUN the solution displaysits WWN the storage group to which it belongs to as well as the hosts member of this group Inmost cases identifying the storage group of a LUN is sufficient to recognize the server that is usingit

52Identifying LUNs not Owned by their Normal(Default) Storage Processor

BMC Performance Manager Express for EMC Disk Arrays

Version 2001

Identifying LUNs not Owned bytheir Normal (Default) StorageProcessorThe Owning Storage Processor parameter reports the name of the controller that handles IOsfor each LUN If a LUN is not currently handled by its normal (default) storage processors the nameof the default controller will be indicated as SP_B (default SP_A)rdquo

To identify LUNs that are not owned by their normal storage processor you simply need to list the Volume objects where the Owning Storage Processor parameter contains the string Default

Identifying Most Busy LUNs

To identify the LUNs that generate the most traffic on the disk array use the Read Byte Rate andWrite Byte Rate parameters of the LUN class that expose the data throughput for each LUN Usethese parameters to report on the total data traffic (per hour or per day) on each LUN in GB

To make sure that traffic is displayed cumulatively per hour select a time window of at least 12 hours in the graphwindow select at least 7 days to visualize per day cumulative data

1 In the Status tab click the Volume for which you need to check the LUNs activity then expandthe LUNs object to display the ReadWrite Byte Rate parameters

53Identifying Most Busy LUNs

54Identifying Most Busy LUNs

BMC Performance Manager Express for EMC Disk Arrays

Version 2001

View ing a LUNs ReadW rite Byte Rate as a graph

Identifying a Storage Processor(Controllers) OverloadTo visualize the activity of a controller in an EMC disk array use the Processor Utilizationparameter of the SEN_EMC_CONTROLLER class A warning is issued when the processor utilizationgoes too high which means that the controllers cannot keep up with the load on the disk array It isthen important to identify what is overloading the controllers

The Response Time parameter of the SEN_EMC_CONTROLLER class represents the average time ittook the controller to process the read and write requests of the hosts The higher the ResponseTime goes the slower IOs the servers will get By default the solution triggers a warning when thecontroller takes more than 10 milliseconds on average to complete the IO requests and an alarmwhen the response time reaches 100 milliseconds

Monitoring the Efficiency of theCaching MechanismEach controller in an EMC disk array can be configured to use a specified amount of memory tocache the read andor write operations The solution reports the amount of memory configured byeach controller for the read and write operations

The Write Flush Byte Rate represents the rate in MBsec at which data is committed to the disk(ie physically written) This value is to be compared with the Write Byte Rate of the disk array

55Monitoring the Efficiency of the CachingMechanism

BMC Performance Manager Express for EMC Disk Arrays

Version 2001

Comparing W rite Flush Byte Rate w ith W rite Byte Rate

The Cache Dirty Pages Percentage parameter represents the amount in percentage of the writecache that has been modified by host write operations and not yet flushed to the disks Reaching100 means that write case is too small and cannot handle the flow of write operations

Checking the Cache Dirty Pages Percentage

Reclaiming Space of Unmapped(Unused) LUNsOver time as servers connected to a SAN get decommissioned administrators find an increasingnumber of unmapped LUNs or volumes that are no longer used by any server These LUNs whileunused still occupy disk space in the disk array Being able to identify such unmapped LUNs andreclaim the disk space uselessly consumed by these LUNs will help administrators avoid unnecessaryupgrades and extensions of their disk arrays

56Reporting a Disk Space Consumption

BMC Performance Manager Express for EMC Disk Arrays

Version 2001

Reporting a Disk SpaceConsumptionMaking sure that a disk array has enough remaining disk space available is critical for severalreasons

middot SAN administrators want to make sure to be able to provision disk space for new servers whenrequested as quickly as possible

middot The disk array itself may need additional disk space for specific features to work properly likeautomatic snapshots mirroring etc

middot If thin provisioning is used the remaining disk space becomes dramatically critical since theinability to allocate additional space to a LUN when requested by the subscriber host will lead tocatastrophic data loss and corruption

The disk space used is permanently monitored for each storage pool The Subscribed Capacityparameter of the Pool class represents the amount of disk space that has been made available tothe subscriber hosts or in other words the amount of disk space that is seen by the serversconnected to disk array

The Consumed Capacity parameter of the SEN_EMC_STORAGEPOOLS class represents the actualspace usage in the storage pool For thin pools (when thin provisioning is enabled on the disk array)this value is normally lower than the Subscribed Capacity as it is the main purpose of thinprovisioning For traditional pools the Consumed Capacity parameters has the same value as theSubscribed Capacity parameter as the entirety of the subscribed disk space is fully allocated inthe storage pool

The Consumed Capacity Percentage parameter is the most critical one as a storage pool usagenearing 100 means that SAN administrators will not be able to create new LUNs in the storagepool By default no alarm or warning threshold is set on this parameter as the fullness of a storagepool may be a normal situation However you can set alert thresholds on this parameter as it fitsyour needs

57Reporting a Disk Space Consumption

BMC Performance Manager Express for EMC Disk Arrays

Version 2001

Verifying the Available Disk Space in the Storage Pool of your EMC DiskArrays

1 In the Configure tab select an element group in the tree view (the main ldquoInfrastructurerdquogroup for example)

2 Click on the Reports tab

3 Create a report for the last 24 hours top 50 values of the Array|Storage Pools|Disk Group|Storage Pool|Consumed Capacity Percentage parameter of the EMC Disk Arraysapplication class for the BMC Performance Manager Express for EMC Disk Arrays by SentrySoftware solution

Report ndash Disk Space Consumption

Reporting the Total Traffic on anHourly or Daily BasisBMC Performance Manager Express for EMC Disk Arrays not only monitors the traffic and activity ofthe disk array controllers LUNs and physical disks in MBsec but also in GB per hour or per day Theexact amount of data that was read or written to the disk array LUN or physical disk is calculated foreach hour of the day and each day of the week

Each data rate parameter in MBsec is accompanied by a non-rate one in GB These parameters areldquocumulativerdquo their instantaneous value has no meaning and they need to be visualized in a longperiod of time (instead of Read Byte Rate or Write Byte Rate)

58Reporting the Total Traffic on an Hourly orDaily Basis

BMC Performance Manager Express for EMC Disk Arrays

Setting thresholds

Whenever relevant BMC Performance Manager Express for EMC Disk Arrays automatically setsthresholds for parameters If you prefer a more fault-tolerant monitoring you can modify thethresholds of each parameter through the Configure tab gt Edit Thresholds

It is strongly recommended to wait for all the storage objects to be discovered before setting threshold values to avoidhaving to enter thresholds for each occurrence of the application class

To modify the parameter thresholds of several storage objects of an element

60Setting thresholds

BMC Performance Manager Express for EMC Disk Arrays

Version 2001

1 In the Configure tab click on the Storage (ltplatformgt) or the instance icon gt Edit

Thresholds Properties and Credentials

Any modification to the thresholds or any other properties of elements created using the Element

Profile mode is to be done using the Element Profile route or by clicking Override Profile

2 Uncheck the Warning and Alarm boxes for all the parameters for which you want to disablethe alert conditions

Disabling the default alert thresholds

61Setting thresholds

BMC Performance Manager Express for EMC Disk Arrays

3 Check the Warning and Alarm boxes for all the parameters for which you want to enable thealert conditions You will then have to manually enter the threshold values and check the Activebox In the example below a Warning will be triggered if Status is greater than 1 an alarm willbe triggered when greater than 2

Modifying threshold values

4 Click Save

5 The Success changes have been saved message indicates that the modifications have beenregistered

Alerts are displayed by the parameter whose thresholds are modified

Viewing the Overall Activity of aDisk ArrayIn order to visualize the activity of a disk array use the Read Byte Rate and Write Byte Rate ofthe SEN_EMC_ARRAY class These parameters represent the overall traffic in megabytes per secondfor each monitored array or more precisely each EMC disk array that is exposed through the EMCSMI-S Provider (see the EMC_SMI-S_Provider section of the Installation Guide for more informationabout the EMC SMI-S Provider)

62Viewing the Overall Activity of a Disk Array

BMC Performance Manager Express for EMC Disk Arrays

Version 2001

Viewing a Disk Array Activity

1 Click the Status tab in Portal

2 Click the array icon in the tree view to visualize its current activity

Selecting a Disk Array Parameter

middot Open Navisphere

middot Right-click the icon for the storage system

middot Click Properties

middot Be sure SP A and SP B are in the Storage Processors section

middot Click the box for Statistics Logging under the Configuration section

2 For locally attached CLARiiONs check if authorization info is present

3 Run the dv command from EMC TestSMIProvider Make sure all arrays are discovered withoutany errors

4 Make sure performance is turned on in the Profile for storage arrays

5 Make sure there are instances for the CIM_BlockStorageStatisticalData class

middot Run Tek-Tools testProvider or EMCrsquos testSMIProvider

middot Type ein for command

middot Type CIM_BlockStorageStatisticalData for Class Name

middot If no instances are returned reset EMC Provider

6 Once complete resume steps 1-3

If you are using a version older than SMIKit 642 the EMC SMI-S Provider does not recognize changes in the arraywhen a LUN or RAID Group is created or deleted from Navisphere It is thus recommended to upgrade your EMC SMI-SProvider to version 642 or higher to benefit from the auto-synchronization mechanism set by default to one hour afterthe last update If you do not upgrade your EMC SMI-S Provider you will have to run the refsys command fromtestsmiprovider each time you create or delete LUN or RAID groups from Navisphere

Managing Baselines and KeyPerformance IndicatorsIn order to facilitate the detection of abnormalities on your monitored environment BMCProactiveNet calculates baselines per parameter (metrics or attributes) based on values collectedover a specified period of time to determine a normal operating range When the collected values forthese parameters are out of range an alert is triggered

Some parameters are identified by default as Key Performance Indicators and therefore automaticallyincluded in the base lining calculation

42Managing Baselines and Key PerformanceIndicators

BMC Performance Manager Express for EMC Disk Arrays

Version 2001

Managing baselines

The baseline is the expected normal operating range for a metric or attribute of a monitor

The baseline is calculated by collecting the values for a monitorrsquos attributes and metrics over aspecified time period and establishing a low baseline value (consisting of the 10th percentile of all thevalues for a given time period) and a high baseline value (consisting of the 90th percentile of all thevalues for a given time period) taking a weighted average of these values over time A higher weightis given to the latest data being factored into the baseline average The accuracy of the baselineimproves over time

Requirements for baseline generation

For baselines to be generated for an attribute that abnormality threshold means that the thresholdexists and is not suppressed Additionally if the Key Performance Indicator (KPI) mode is active only those attributes that have anactive abnormality threshold and are also KPI attributes will have baselines generated for them

Absolute thresholds (with outside baseline) or signature thresholds do not satisfy these requirements

Managing Key Performance Indicators

The KPI attribute of a parameter can be activated or deactivated manually through the BMCProactiveNet Administration Console In this PM some parameters or attributes have beendesignated as important indicators of performance (KPIs) We do not recommend that these defaultsettings are modified

However advanced users may activate or deactivate KPIs from the BMC ProactiveNet AdministrationConsole

To add or remove Key Performance Indicator (KPI) attributes for amonitor type

1 In the Administration Console from the menu bar choose Tools gt KPI AdministrationThe KPI Administration dialog box is displayed

2 From the Monitor Type list choose the monitor type for which you want to add or remove KPIattributes A list of attributes for the selected monitor type is displayed

3 In the KPI column for the attributes that you want to add or remove as Key PerformanceIndicators

middot select the KPI check box to add the corresponding attribute as a KPI

middot deselect the KPI check box to remove the corresponding attribute from the KPIs for thatmonitor type

For complete and detailed information on this procedure please refer to the BMC ProactiveNet documentation availablefrom BMC Web site

BMC Performance Manager Express for EMC Disk Arrays

Version 2001

BMC Performance Manager Express for EMC Disk Arrays monitors all of the performance metrics andusage statistics of your EMC disk arrays such as file disk space usage storage controller utilizationIOs on the diskscontrollersvolumes etc It continuously monitors the activity of each array and isalso able to build reports on past utilization statistics

To setup a complete monitoring of the array we strongly recommend you to also use BMCPerformance Manager Express for Hardware that covers all the physical aspect of the EMC diskarrays (status of the disks ports temperature power supplies power consumption etc)

This chapter explains how to use each monitoring tool ie a separate application class within theBMC Performance Manager Express for EMC Disk Arrays by Sentry Software solution

BMC Performance Manager Express for EMC Disk Arrays is a Performance Manager specifically designedfor BMC Portal consequently it uses the same common features and procedures of BMCreg Portal Thisdocument assumes that the user knows how to use the Portal and therefore explains procedures onlyrelated to BMC Performance Manager Express for EMC Disk Arrays and not on how to add ElementsElement Profiles etc Please refer to the BMC Portal documentation for details on how to use the Portal

Checking Available Spare Disks

To avoid any loss of critical data it is essential for a disk array to always maintain a pool of sparedisks that can replace the faulty disk when a disk failure occurs A disk array without any left sparedisk will not be able to keep the level of data safety and performance in case of a disk failure

The Spare Disk Count parameter of the SEN_EMC_ARRAY class reports the number of spare disksavailable for each disk array monitored with the solution By default a warning is triggered when nospare disk is available (Spare Disk Count is set to zero)

Verifying the Number of Available Spare Disks in Your EMC Disk Arrays

49Checking Available Spare Disks

BMC Performance Manager Express for EMC Disk Arrays

Version 2001

1 Select an element group in the tree view (the main Infrastructure group for example)

2 Click the Reports tab Create a report for the last 24 hours bottom 50 values of the Array|Spare Disk Count parameter of the EMC Disk Arrays application class for the BMC PerformanceManager Express for EMC Disk Arrays by Sentry Software solution

Report ndash Available Spare Disks

Detecting OversubscriptionSituations (Thin Provisioning)We call an oversubscription situation when

1 The storage pool is configured for thin provisioning (ldquothin storage poolrdquo)

2 The storage pool is oversubscribed ie the total disk space visible to the hosts (subscribers) isgreater than its actual capacity (this situation is normal for a thin pool since it is its very purpose)

3 The storage pool actual consumed capacity is nearing 100

Such situation is highly critical because the inability to allocate additional space to a LUN whenrequested by the subscriber host will lead to catastrophic data loss and corruption

When the conditions described above are met the solution sets the Oversubscription Situationparameter to 1 automatically raising a warning By default the warning for OversubscriptionSituation is issued when the Consumed Capacity Percentage parameter goes above 100 Thisthreshold can be configured in the input properties of the solution

50Detecting Oversubscription Situations (ThinProvisioning)

BMC Performance Manager Express for EMC Disk Arrays

Version 2001

Configuring Oversubscription Threshold

1 Click the EMC Disk Arrays icon and then the Configure tab

2 Edit the Oversubscription Situation Threshold () property to the appropriate value Whenthe Oversubscription Situation parameter triggers a warning it is highly recommended thatthe SAN administrators add capacity to the storage pool as soon as possible

Diagnosing Slow LUNs

If a system administrator complains that his servers are experiencing slow IOs performance and thatit is caused by the SAN you may want to verify the actual response time of the LUNs the server isrelying on

The Response Time parameter of the SEN_EMC_VOLUME class represents the average time it tookto complete the read and write operations on the LUN during the collection interval Typically theaverage response time is below 10 milliseconds You may also want to compare this value to theresponse time of the other LUNs to see whether one server is really getting worse IO performancethan another

Volume - Response Time Parameter

If the response time is low you will need to check the amount of data that is written and read onthis LUN The bad performance may simply be due to an abnormally large amount of data to processOtherwise the problem is maybe between the disk array and the server in the fiber links

51Enabling the Debug Mode

BMC Performance Manager Express for EMC Disk Arrays

Version 2001

Enabling the Debug Mode

By default BMC Performance Manager Express for EMC Disk Arrays sends only the most criticalinformation warning and error messages to the Application Collection Status parameter Mostoften this information is accurate enough to ensure that BMC Performance Manager Express for EMCDisk Arrays is functioning properly If you encounter an issue and wish to report it to customersupport you will be asked to enable the Debug Mode and provide the debug output to the supportteam

1 In the Configure tab gt under Tasks click Elements

2 Select the Element whose debug output you require and click Edit

3 Scroll down to Application Classes gt click the Application class for which you want toenable the debug mode gt click Edit

4 Select Yes from the drop-down Debug Mode list gt SaveBy default BMC Performance Manager Express for EMC Disk Arrays sends its debug output to RSM_HOMERSM(xx)serverrsmlogsen_debuglog

5 Wait for 15 minutes and then disable the debug mode by selecting No

6 Send the debug file to the support team

Pay attention to the file size -the debug output of BMC Performance Manager Express for EMC Disk Arrays could bevery large if enabled for several days

Identifying the Hosts that canAccess a LUNIn most SAN configurations each LUN belongs to a storage group whose host members are the onlyones authorized to access the LUN This is called LUN masking For each LUN the solution displaysits WWN the storage group to which it belongs to as well as the hosts member of this group Inmost cases identifying the storage group of a LUN is sufficient to recognize the server that is usingit

52Identifying LUNs not Owned by their Normal(Default) Storage Processor

BMC Performance Manager Express for EMC Disk Arrays

Version 2001

Identifying LUNs not Owned bytheir Normal (Default) StorageProcessorThe Owning Storage Processor parameter reports the name of the controller that handles IOsfor each LUN If a LUN is not currently handled by its normal (default) storage processors the nameof the default controller will be indicated as SP_B (default SP_A)rdquo

To identify LUNs that are not owned by their normal storage processor you simply need to list the Volume objects where the Owning Storage Processor parameter contains the string Default

Identifying Most Busy LUNs

To identify the LUNs that generate the most traffic on the disk array use the Read Byte Rate andWrite Byte Rate parameters of the LUN class that expose the data throughput for each LUN Usethese parameters to report on the total data traffic (per hour or per day) on each LUN in GB

To make sure that traffic is displayed cumulatively per hour select a time window of at least 12 hours in the graphwindow select at least 7 days to visualize per day cumulative data

1 In the Status tab click the Volume for which you need to check the LUNs activity then expandthe LUNs object to display the ReadWrite Byte Rate parameters

53Identifying Most Busy LUNs

54Identifying Most Busy LUNs

BMC Performance Manager Express for EMC Disk Arrays

Version 2001

View ing a LUNs ReadW rite Byte Rate as a graph

Identifying a Storage Processor(Controllers) OverloadTo visualize the activity of a controller in an EMC disk array use the Processor Utilizationparameter of the SEN_EMC_CONTROLLER class A warning is issued when the processor utilizationgoes too high which means that the controllers cannot keep up with the load on the disk array It isthen important to identify what is overloading the controllers

The Response Time parameter of the SEN_EMC_CONTROLLER class represents the average time ittook the controller to process the read and write requests of the hosts The higher the ResponseTime goes the slower IOs the servers will get By default the solution triggers a warning when thecontroller takes more than 10 milliseconds on average to complete the IO requests and an alarmwhen the response time reaches 100 milliseconds

Monitoring the Efficiency of theCaching MechanismEach controller in an EMC disk array can be configured to use a specified amount of memory tocache the read andor write operations The solution reports the amount of memory configured byeach controller for the read and write operations

The Write Flush Byte Rate represents the rate in MBsec at which data is committed to the disk(ie physically written) This value is to be compared with the Write Byte Rate of the disk array

55Monitoring the Efficiency of the CachingMechanism

BMC Performance Manager Express for EMC Disk Arrays

Version 2001

Comparing W rite Flush Byte Rate w ith W rite Byte Rate

The Cache Dirty Pages Percentage parameter represents the amount in percentage of the writecache that has been modified by host write operations and not yet flushed to the disks Reaching100 means that write case is too small and cannot handle the flow of write operations

Checking the Cache Dirty Pages Percentage

Reclaiming Space of Unmapped(Unused) LUNsOver time as servers connected to a SAN get decommissioned administrators find an increasingnumber of unmapped LUNs or volumes that are no longer used by any server These LUNs whileunused still occupy disk space in the disk array Being able to identify such unmapped LUNs andreclaim the disk space uselessly consumed by these LUNs will help administrators avoid unnecessaryupgrades and extensions of their disk arrays

56Reporting a Disk Space Consumption

BMC Performance Manager Express for EMC Disk Arrays

Version 2001

Reporting a Disk SpaceConsumptionMaking sure that a disk array has enough remaining disk space available is critical for severalreasons

middot SAN administrators want to make sure to be able to provision disk space for new servers whenrequested as quickly as possible

middot The disk array itself may need additional disk space for specific features to work properly likeautomatic snapshots mirroring etc

middot If thin provisioning is used the remaining disk space becomes dramatically critical since theinability to allocate additional space to a LUN when requested by the subscriber host will lead tocatastrophic data loss and corruption

The disk space used is permanently monitored for each storage pool The Subscribed Capacityparameter of the Pool class represents the amount of disk space that has been made available tothe subscriber hosts or in other words the amount of disk space that is seen by the serversconnected to disk array

The Consumed Capacity parameter of the SEN_EMC_STORAGEPOOLS class represents the actualspace usage in the storage pool For thin pools (when thin provisioning is enabled on the disk array)this value is normally lower than the Subscribed Capacity as it is the main purpose of thinprovisioning For traditional pools the Consumed Capacity parameters has the same value as theSubscribed Capacity parameter as the entirety of the subscribed disk space is fully allocated inthe storage pool

The Consumed Capacity Percentage parameter is the most critical one as a storage pool usagenearing 100 means that SAN administrators will not be able to create new LUNs in the storagepool By default no alarm or warning threshold is set on this parameter as the fullness of a storagepool may be a normal situation However you can set alert thresholds on this parameter as it fitsyour needs

57Reporting a Disk Space Consumption

BMC Performance Manager Express for EMC Disk Arrays

Version 2001

Verifying the Available Disk Space in the Storage Pool of your EMC DiskArrays

1 In the Configure tab select an element group in the tree view (the main ldquoInfrastructurerdquogroup for example)

2 Click on the Reports tab

3 Create a report for the last 24 hours top 50 values of the Array|Storage Pools|Disk Group|Storage Pool|Consumed Capacity Percentage parameter of the EMC Disk Arraysapplication class for the BMC Performance Manager Express for EMC Disk Arrays by SentrySoftware solution

Report ndash Disk Space Consumption

Reporting the Total Traffic on anHourly or Daily BasisBMC Performance Manager Express for EMC Disk Arrays not only monitors the traffic and activity ofthe disk array controllers LUNs and physical disks in MBsec but also in GB per hour or per day Theexact amount of data that was read or written to the disk array LUN or physical disk is calculated foreach hour of the day and each day of the week

Each data rate parameter in MBsec is accompanied by a non-rate one in GB These parameters areldquocumulativerdquo their instantaneous value has no meaning and they need to be visualized in a longperiod of time (instead of Read Byte Rate or Write Byte Rate)

58Reporting the Total Traffic on an Hourly orDaily Basis

Setting thresholds

Whenever relevant BMC Performance Manager Express for EMC Disk Arrays automatically setsthresholds for parameters If you prefer a more fault-tolerant monitoring you can modify thethresholds of each parameter through the Configure tab gt Edit Thresholds

It is strongly recommended to wait for all the storage objects to be discovered before setting threshold values to avoidhaving to enter thresholds for each occurrence of the application class

To modify the parameter thresholds of several storage objects of an element

60Setting thresholds

BMC Performance Manager Express for EMC Disk Arrays

Version 2001

1 In the Configure tab click on the Storage (ltplatformgt) or the instance icon gt Edit

Thresholds Properties and Credentials

Any modification to the thresholds or any other properties of elements created using the Element

Profile mode is to be done using the Element Profile route or by clicking Override Profile

2 Uncheck the Warning and Alarm boxes for all the parameters for which you want to disablethe alert conditions

3 Check the Warning and Alarm boxes for all the parameters for which you want to enable thealert conditions You will then have to manually enter the threshold values and check the Activebox In the example below a Warning will be triggered if Status is greater than 1 an alarm willbe triggered when greater than 2

Modifying threshold values

4 Click Save

5 The Success changes have been saved message indicates that the modifications have beenregistered

Alerts are displayed by the parameter whose thresholds are modified

Viewing the Overall Activity of aDisk ArrayIn order to visualize the activity of a disk array use the Read Byte Rate and Write Byte Rate ofthe SEN_EMC_ARRAY class These parameters represent the overall traffic in megabytes per secondfor each monitored array or more precisely each EMC disk array that is exposed through the EMCSMI-S Provider (see the EMC_SMI-S_Provider section of the Installation Guide for more informationabout the EMC SMI-S Provider)

62Viewing the Overall Activity of a Disk Array

BMC Performance Manager Express for EMC Disk Arrays

Viewing a Disk Array Activity

1 Click the Status tab in Portal

2 Click the array icon in the tree view to visualize its current activity

Managing Baselines and KeyPerformance IndicatorsIn order to facilitate the detection of abnormalities on your monitored environment BMCProactiveNet calculates baselines per parameter (metrics or attributes) based on values collectedover a specified period of time to determine a normal operating range When the collected values forthese parameters are out of range an alert is triggered

Some parameters are identified by default as Key Performance Indicators and therefore automaticallyincluded in the base lining calculation

42Managing Baselines and Key PerformanceIndicators

BMC Performance Manager Express for EMC Disk Arrays

Version 2001

Managing baselines

The baseline is the expected normal operating range for a metric or attribute of a monitor

The baseline is calculated by collecting the values for a monitorrsquos attributes and metrics over aspecified time period and establishing a low baseline value (consisting of the 10th percentile of all thevalues for a given time period) and a high baseline value (consisting of the 90th percentile of all thevalues for a given time period) taking a weighted average of these values over time A higher weightis given to the latest data being factored into the baseline average The accuracy of the baselineimproves over time

Requirements for baseline generation

For baselines to be generated for an attribute that abnormality threshold means that the thresholdexists and is not suppressed Additionally if the Key Performance Indicator (KPI) mode is active only those attributes that have anactive abnormality threshold and are also KPI attributes will have baselines generated for them

Absolute thresholds (with outside baseline) or signature thresholds do not satisfy these requirements

Managing Key Performance Indicators

The KPI attribute of a parameter can be activated or deactivated manually through the BMCProactiveNet Administration Console In this PM some parameters or attributes have beendesignated as important indicators of performance (KPIs) We do not recommend that these defaultsettings are modified

However advanced users may activate or deactivate KPIs from the BMC ProactiveNet AdministrationConsole

To add or remove Key Performance Indicator (KPI) attributes for amonitor type

1 In the Administration Console from the menu bar choose Tools gt KPI AdministrationThe KPI Administration dialog box is displayed

2 From the Monitor Type list choose the monitor type for which you want to add or remove KPIattributes A list of attributes for the selected monitor type is displayed

3 In the KPI column for the attributes that you want to add or remove as Key PerformanceIndicators

middot select the KPI check box to add the corresponding attribute as a KPI

middot deselect the KPI check box to remove the corresponding attribute from the KPIs for thatmonitor type

For complete and detailed information on this procedure please refer to the BMC ProactiveNet documentation availablefrom BMC Web site

BMC Performance Manager Express for EMC Disk Arrays is a Performance Manager specifically designedfor BMC Portal consequently it uses the same common features and procedures of BMCreg Portal Thisdocument assumes that the user knows how to use the Portal and therefore explains procedures onlyrelated to BMC Performance Manager Express for EMC Disk Arrays and not on how to add ElementsElement Profiles etc Please refer to the BMC Portal documentation for details on how to use the Portal

Checking Available Spare Disks

To avoid any loss of critical data it is essential for a disk array to always maintain a pool of sparedisks that can replace the faulty disk when a disk failure occurs A disk array without any left sparedisk will not be able to keep the level of data safety and performance in case of a disk failure

The Spare Disk Count parameter of the SEN_EMC_ARRAY class reports the number of spare disksavailable for each disk array monitored with the solution By default a warning is triggered when nospare disk is available (Spare Disk Count is set to zero)

Verifying the Number of Available Spare Disks in Your EMC Disk Arrays

49Checking Available Spare Disks

BMC Performance Manager Express for EMC Disk Arrays

Version 2001

1 Select an element group in the tree view (the main Infrastructure group for example)

2 Click the Reports tab Create a report for the last 24 hours bottom 50 values of the Array|Spare Disk Count parameter of the EMC Disk Arrays application class for the BMC PerformanceManager Express for EMC Disk Arrays by Sentry Software solution

Detecting OversubscriptionSituations (Thin Provisioning)We call an oversubscription situation when

1 The storage pool is configured for thin provisioning (ldquothin storage poolrdquo)

2 The storage pool is oversubscribed ie the total disk space visible to the hosts (subscribers) isgreater than its actual capacity (this situation is normal for a thin pool since it is its very purpose)

3 The storage pool actual consumed capacity is nearing 100

Such situation is highly critical because the inability to allocate additional space to a LUN whenrequested by the subscriber host will lead to catastrophic data loss and corruption

When the conditions described above are met the solution sets the Oversubscription Situationparameter to 1 automatically raising a warning By default the warning for OversubscriptionSituation is issued when the Consumed Capacity Percentage parameter goes above 100 Thisthreshold can be configured in the input properties of the solution

50Detecting Oversubscription Situations (ThinProvisioning)

BMC Performance Manager Express for EMC Disk Arrays

Version 2001

Configuring Oversubscription Threshold

1 Click the EMC Disk Arrays icon and then the Configure tab

2 Edit the Oversubscription Situation Threshold () property to the appropriate value Whenthe Oversubscription Situation parameter triggers a warning it is highly recommended thatthe SAN administrators add capacity to the storage pool as soon as possible

Diagnosing Slow LUNs

If a system administrator complains that his servers are experiencing slow IOs performance and thatit is caused by the SAN you may want to verify the actual response time of the LUNs the server isrelying on

The Response Time parameter of the SEN_EMC_VOLUME class represents the average time it tookto complete the read and write operations on the LUN during the collection interval Typically theaverage response time is below 10 milliseconds You may also want to compare this value to theresponse time of the other LUNs to see whether one server is really getting worse IO performancethan another

Volume - Response Time Parameter

If the response time is low you will need to check the amount of data that is written and read onthis LUN The bad performance may simply be due to an abnormally large amount of data to processOtherwise the problem is maybe between the disk array and the server in the fiber links

51Enabling the Debug Mode

BMC Performance Manager Express for EMC Disk Arrays

Version 2001

Enabling the Debug Mode

By default BMC Performance Manager Express for EMC Disk Arrays sends only the most criticalinformation warning and error messages to the Application Collection Status parameter Mostoften this information is accurate enough to ensure that BMC Performance Manager Express for EMCDisk Arrays is functioning properly If you encounter an issue and wish to report it to customersupport you will be asked to enable the Debug Mode and provide the debug output to the supportteam

1 In the Configure tab gt under Tasks click Elements

2 Select the Element whose debug output you require and click Edit

3 Scroll down to Application Classes gt click the Application class for which you want toenable the debug mode gt click Edit

4 Select Yes from the drop-down Debug Mode list gt SaveBy default BMC Performance Manager Express for EMC Disk Arrays sends its debug output to RSM_HOMERSM(xx)serverrsmlogsen_debuglog

5 Wait for 15 minutes and then disable the debug mode by selecting No

6 Send the debug file to the support team

Pay attention to the file size -the debug output of BMC Performance Manager Express for EMC Disk Arrays could bevery large if enabled for several days

Identifying the Hosts that canAccess a LUNIn most SAN configurations each LUN belongs to a storage group whose host members are the onlyones authorized to access the LUN This is called LUN masking For each LUN the solution displaysits WWN the storage group to which it belongs to as well as the hosts member of this group Inmost cases identifying the storage group of a LUN is sufficient to recognize the server that is usingit

52Identifying LUNs not Owned by their Normal(Default) Storage Processor

BMC Performance Manager Express for EMC Disk Arrays

Version 2001

Identifying LUNs not Owned bytheir Normal (Default) StorageProcessorThe Owning Storage Processor parameter reports the name of the controller that handles IOsfor each LUN If a LUN is not currently handled by its normal (default) storage processors the nameof the default controller will be indicated as SP_B (default SP_A)rdquo

To identify LUNs that are not owned by their normal storage processor you simply need to list the Volume objects where the Owning Storage Processor parameter contains the string Default

Identifying Most Busy LUNs

To identify the LUNs that generate the most traffic on the disk array use the Read Byte Rate andWrite Byte Rate parameters of the LUN class that expose the data throughput for each LUN Usethese parameters to report on the total data traffic (per hour or per day) on each LUN in GB

To make sure that traffic is displayed cumulatively per hour select a time window of at least 12 hours in the graphwindow select at least 7 days to visualize per day cumulative data

1 In the Status tab click the Volume for which you need to check the LUNs activity then expandthe LUNs object to display the ReadWrite Byte Rate parameters

53Identifying Most Busy LUNs

54Identifying Most Busy LUNs

BMC Performance Manager Express for EMC Disk Arrays

Version 2001

View ing a LUNs ReadW rite Byte Rate as a graph

Identifying a Storage Processor(Controllers) OverloadTo visualize the activity of a controller in an EMC disk array use the Processor Utilizationparameter of the SEN_EMC_CONTROLLER class A warning is issued when the processor utilizationgoes too high which means that the controllers cannot keep up with the load on the disk array It isthen important to identify what is overloading the controllers

The Response Time parameter of the SEN_EMC_CONTROLLER class represents the average time ittook the controller to process the read and write requests of the hosts The higher the ResponseTime goes the slower IOs the servers will get By default the solution triggers a warning when thecontroller takes more than 10 milliseconds on average to complete the IO requests and an alarmwhen the response time reaches 100 milliseconds

Monitoring the Efficiency of theCaching MechanismEach controller in an EMC disk array can be configured to use a specified amount of memory tocache the read andor write operations The solution reports the amount of memory configured byeach controller for the read and write operations

The Write Flush Byte Rate represents the rate in MBsec at which data is committed to the disk(ie physically written) This value is to be compared with the Write Byte Rate of the disk array

55Monitoring the Efficiency of the CachingMechanism

BMC Performance Manager Express for EMC Disk Arrays

Version 2001

Comparing W rite Flush Byte Rate w ith W rite Byte Rate

The Cache Dirty Pages Percentage parameter represents the amount in percentage of the writecache that has been modified by host write operations and not yet flushed to the disks Reaching100 means that write case is too small and cannot handle the flow of write operations

Checking the Cache Dirty Pages Percentage

Reclaiming Space of Unmapped(Unused) LUNsOver time as servers connected to a SAN get decommissioned administrators find an increasingnumber of unmapped LUNs or volumes that are no longer used by any server These LUNs whileunused still occupy disk space in the disk array Being able to identify such unmapped LUNs andreclaim the disk space uselessly consumed by these LUNs will help administrators avoid unnecessaryupgrades and extensions of their disk arrays

56Reporting a Disk Space Consumption

BMC Performance Manager Express for EMC Disk Arrays

Version 2001

Reporting a Disk SpaceConsumptionMaking sure that a disk array has enough remaining disk space available is critical for severalreasons

middot SAN administrators want to make sure to be able to provision disk space for new servers whenrequested as quickly as possible

middot The disk array itself may need additional disk space for specific features to work properly likeautomatic snapshots mirroring etc

middot If thin provisioning is used the remaining disk space becomes dramatically critical since theinability to allocate additional space to a LUN when requested by the subscriber host will lead tocatastrophic data loss and corruption

The disk space used is permanently monitored for each storage pool The Subscribed Capacityparameter of the Pool class represents the amount of disk space that has been made available tothe subscriber hosts or in other words the amount of disk space that is seen by the serversconnected to disk array

The Consumed Capacity parameter of the SEN_EMC_STORAGEPOOLS class represents the actualspace usage in the storage pool For thin pools (when thin provisioning is enabled on the disk array)this value is normally lower than the Subscribed Capacity as it is the main purpose of thinprovisioning For traditional pools the Consumed Capacity parameters has the same value as theSubscribed Capacity parameter as the entirety of the subscribed disk space is fully allocated inthe storage pool

The Consumed Capacity Percentage parameter is the most critical one as a storage pool usagenearing 100 means that SAN administrators will not be able to create new LUNs in the storagepool By default no alarm or warning threshold is set on this parameter as the fullness of a storagepool may be a normal situation However you can set alert thresholds on this parameter as it fitsyour needs

Report ndash Disk Space Consumption

Reporting the Total Traffic on anHourly or Daily BasisBMC Performance Manager Express for EMC Disk Arrays not only monitors the traffic and activity ofthe disk array controllers LUNs and physical disks in MBsec but also in GB per hour or per day Theexact amount of data that was read or written to the disk array LUN or physical disk is calculated foreach hour of the day and each day of the week

Each data rate parameter in MBsec is accompanied by a non-rate one in GB These parameters areldquocumulativerdquo their instantaneous value has no meaning and they need to be visualized in a longperiod of time (instead of Read Byte Rate or Write Byte Rate)

Setting thresholds

Whenever relevant BMC Performance Manager Express for EMC Disk Arrays automatically setsthresholds for parameters If you prefer a more fault-tolerant monitoring you can modify thethresholds of each parameter through the Configure tab gt Edit Thresholds

It is strongly recommended to wait for all the storage objects to be discovered before setting threshold values to avoidhaving to enter thresholds for each occurrence of the application class

To modify the parameter thresholds of several storage objects of an element

60Setting thresholds

BMC Performance Manager Express for EMC Disk Arrays

Version 2001

1 In the Configure tab click on the Storage (ltplatformgt) or the instance icon gt Edit

Thresholds Properties and Credentials

Any modification to the thresholds or any other properties of elements created using the Element

Profile mode is to be done using the Element Profile route or by clicking Override Profile

2 Uncheck the Warning and Alarm boxes for all the parameters for which you want to disablethe alert conditions

Managing Baselines and KeyPerformance IndicatorsIn order to facilitate the detection of abnormalities on your monitored environment BMCProactiveNet calculates baselines per parameter (metrics or attributes) based on values collectedover a specified period of time to determine a normal operating range When the collected values forthese parameters are out of range an alert is triggered

Some parameters are identified by default as Key Performance Indicators and therefore automaticallyincluded in the base lining calculation

42Managing Baselines and Key PerformanceIndicators

BMC Performance Manager Express for EMC Disk Arrays

Version 2001

Managing baselines

The baseline is the expected normal operating range for a metric or attribute of a monitor

The baseline is calculated by collecting the values for a monitorrsquos attributes and metrics over aspecified time period and establishing a low baseline value (consisting of the 10th percentile of all thevalues for a given time period) and a high baseline value (consisting of the 90th percentile of all thevalues for a given time period) taking a weighted average of these values over time A higher weightis given to the latest data being factored into the baseline average The accuracy of the baselineimproves over time

Requirements for baseline generation

For baselines to be generated for an attribute that abnormality threshold means that the thresholdexists and is not suppressed Additionally if the Key Performance Indicator (KPI) mode is active only those attributes that have anactive abnormality threshold and are also KPI attributes will have baselines generated for them

Absolute thresholds (with outside baseline) or signature thresholds do not satisfy these requirements

Managing Key Performance Indicators

The KPI attribute of a parameter can be activated or deactivated manually through the BMCProactiveNet Administration Console In this PM some parameters or attributes have beendesignated as important indicators of performance (KPIs) We do not recommend that these defaultsettings are modified

However advanced users may activate or deactivate KPIs from the BMC ProactiveNet AdministrationConsole

To add or remove Key Performance Indicator (KPI) attributes for amonitor type

1 In the Administration Console from the menu bar choose Tools gt KPI AdministrationThe KPI Administration dialog box is displayed

2 From the Monitor Type list choose the monitor type for which you want to add or remove KPIattributes A list of attributes for the selected monitor type is displayed

3 In the KPI column for the attributes that you want to add or remove as Key PerformanceIndicators

middot select the KPI check box to add the corresponding attribute as a KPI

middot deselect the KPI check box to remove the corresponding attribute from the KPIs for thatmonitor type

For complete and detailed information on this procedure please refer to the BMC ProactiveNet documentation availablefrom BMC Web site

Checking Available Spare Disks

To avoid any loss of critical data it is essential for a disk array to always maintain a pool of sparedisks that can replace the faulty disk when a disk failure occurs A disk array without any left sparedisk will not be able to keep the level of data safety and performance in case of a disk failure

The Spare Disk Count parameter of the SEN_EMC_ARRAY class reports the number of spare disksavailable for each disk array monitored with the solution By default a warning is triggered when nospare disk is available (Spare Disk Count is set to zero)

Verifying the Number of Available Spare Disks in Your EMC Disk Arrays

49Checking Available Spare Disks

BMC Performance Manager Express for EMC Disk Arrays

Version 2001

1 Select an element group in the tree view (the main Infrastructure group for example)

2 Click the Reports tab Create a report for the last 24 hours bottom 50 values of the Array|Spare Disk Count parameter of the EMC Disk Arrays application class for the BMC PerformanceManager Express for EMC Disk Arrays by Sentry Software solution

Detecting OversubscriptionSituations (Thin Provisioning)We call an oversubscription situation when

1 The storage pool is configured for thin provisioning (ldquothin storage poolrdquo)

2 The storage pool is oversubscribed ie the total disk space visible to the hosts (subscribers) isgreater than its actual capacity (this situation is normal for a thin pool since it is its very purpose)

3 The storage pool actual consumed capacity is nearing 100

Such situation is highly critical because the inability to allocate additional space to a LUN whenrequested by the subscriber host will lead to catastrophic data loss and corruption

When the conditions described above are met the solution sets the Oversubscription Situationparameter to 1 automatically raising a warning By default the warning for OversubscriptionSituation is issued when the Consumed Capacity Percentage parameter goes above 100 Thisthreshold can be configured in the input properties of the solution

50Detecting Oversubscription Situations (ThinProvisioning)

BMC Performance Manager Express for EMC Disk Arrays

Version 2001

Configuring Oversubscription Threshold

1 Click the EMC Disk Arrays icon and then the Configure tab

2 Edit the Oversubscription Situation Threshold () property to the appropriate value Whenthe Oversubscription Situation parameter triggers a warning it is highly recommended thatthe SAN administrators add capacity to the storage pool as soon as possible

Diagnosing Slow LUNs

If a system administrator complains that his servers are experiencing slow IOs performance and thatit is caused by the SAN you may want to verify the actual response time of the LUNs the server isrelying on

The Response Time parameter of the SEN_EMC_VOLUME class represents the average time it tookto complete the read and write operations on the LUN during the collection interval Typically theaverage response time is below 10 milliseconds You may also want to compare this value to theresponse time of the other LUNs to see whether one server is really getting worse IO performancethan another

Volume - Response Time Parameter

If the response time is low you will need to check the amount of data that is written and read onthis LUN The bad performance may simply be due to an abnormally large amount of data to processOtherwise the problem is maybe between the disk array and the server in the fiber links

51Enabling the Debug Mode

BMC Performance Manager Express for EMC Disk Arrays

Version 2001

Enabling the Debug Mode

By default BMC Performance Manager Express for EMC Disk Arrays sends only the most criticalinformation warning and error messages to the Application Collection Status parameter Mostoften this information is accurate enough to ensure that BMC Performance Manager Express for EMCDisk Arrays is functioning properly If you encounter an issue and wish to report it to customersupport you will be asked to enable the Debug Mode and provide the debug output to the supportteam

1 In the Configure tab gt under Tasks click Elements

2 Select the Element whose debug output you require and click Edit

3 Scroll down to Application Classes gt click the Application class for which you want toenable the debug mode gt click Edit

4 Select Yes from the drop-down Debug Mode list gt SaveBy default BMC Performance Manager Express for EMC Disk Arrays sends its debug output to RSM_HOMERSM(xx)serverrsmlogsen_debuglog

5 Wait for 15 minutes and then disable the debug mode by selecting No

6 Send the debug file to the support team

Pay attention to the file size -the debug output of BMC Performance Manager Express for EMC Disk Arrays could bevery large if enabled for several days

Identifying the Hosts that canAccess a LUNIn most SAN configurations each LUN belongs to a storage group whose host members are the onlyones authorized to access the LUN This is called LUN masking For each LUN the solution displaysits WWN the storage group to which it belongs to as well as the hosts member of this group Inmost cases identifying the storage group of a LUN is sufficient to recognize the server that is usingit

52Identifying LUNs not Owned by their Normal(Default) Storage Processor

BMC Performance Manager Express for EMC Disk Arrays

Version 2001

Identifying LUNs not Owned bytheir Normal (Default) StorageProcessorThe Owning Storage Processor parameter reports the name of the controller that handles IOsfor each LUN If a LUN is not currently handled by its normal (default) storage processors the nameof the default controller will be indicated as SP_B (default SP_A)rdquo

To identify LUNs that are not owned by their normal storage processor you simply need to list the Volume objects where the Owning Storage Processor parameter contains the string Default

Identifying Most Busy LUNs

To identify the LUNs that generate the most traffic on the disk array use the Read Byte Rate andWrite Byte Rate parameters of the LUN class that expose the data throughput for each LUN Usethese parameters to report on the total data traffic (per hour or per day) on each LUN in GB

To make sure that traffic is displayed cumulatively per hour select a time window of at least 12 hours in the graphwindow select at least 7 days to visualize per day cumulative data

1 In the Status tab click the Volume for which you need to check the LUNs activity then expandthe LUNs object to display the ReadWrite Byte Rate parameters

54Identifying Most Busy LUNs

BMC Performance Manager Express for EMC Disk Arrays

Version 2001

View ing a LUNs ReadW rite Byte Rate as a graph

Identifying a Storage Processor(Controllers) OverloadTo visualize the activity of a controller in an EMC disk array use the Processor Utilizationparameter of the SEN_EMC_CONTROLLER class A warning is issued when the processor utilizationgoes too high which means that the controllers cannot keep up with the load on the disk array It isthen important to identify what is overloading the controllers

The Response Time parameter of the SEN_EMC_CONTROLLER class represents the average time ittook the controller to process the read and write requests of the hosts The higher the ResponseTime goes the slower IOs the servers will get By default the solution triggers a warning when thecontroller takes more than 10 milliseconds on average to complete the IO requests and an alarmwhen the response time reaches 100 milliseconds

Monitoring the Efficiency of theCaching MechanismEach controller in an EMC disk array can be configured to use a specified amount of memory tocache the read andor write operations The solution reports the amount of memory configured byeach controller for the read and write operations

The Write Flush Byte Rate represents the rate in MBsec at which data is committed to the disk(ie physically written) This value is to be compared with the Write Byte Rate of the disk array

55Monitoring the Efficiency of the CachingMechanism

BMC Performance Manager Express for EMC Disk Arrays

Version 2001

Comparing W rite Flush Byte Rate w ith W rite Byte Rate

The Cache Dirty Pages Percentage parameter represents the amount in percentage of the writecache that has been modified by host write operations and not yet flushed to the disks Reaching100 means that write case is too small and cannot handle the flow of write operations

Checking the Cache Dirty Pages Percentage

Reclaiming Space of Unmapped(Unused) LUNsOver time as servers connected to a SAN get decommissioned administrators find an increasingnumber of unmapped LUNs or volumes that are no longer used by any server These LUNs whileunused still occupy disk space in the disk array Being able to identify such unmapped LUNs andreclaim the disk space uselessly consumed by these LUNs will help administrators avoid unnecessaryupgrades and extensions of their disk arrays

56Reporting a Disk Space Consumption

BMC Performance Manager Express for EMC Disk Arrays

Version 2001

Reporting a Disk SpaceConsumptionMaking sure that a disk array has enough remaining disk space available is critical for severalreasons

middot SAN administrators want to make sure to be able to provision disk space for new servers whenrequested as quickly as possible

middot The disk array itself may need additional disk space for specific features to work properly likeautomatic snapshots mirroring etc

middot If thin provisioning is used the remaining disk space becomes dramatically critical since theinability to allocate additional space to a LUN when requested by the subscriber host will lead tocatastrophic data loss and corruption

The disk space used is permanently monitored for each storage pool The Subscribed Capacityparameter of the Pool class represents the amount of disk space that has been made available tothe subscriber hosts or in other words the amount of disk space that is seen by the serversconnected to disk array

The Consumed Capacity parameter of the SEN_EMC_STORAGEPOOLS class represents the actualspace usage in the storage pool For thin pools (when thin provisioning is enabled on the disk array)this value is normally lower than the Subscribed Capacity as it is the main purpose of thinprovisioning For traditional pools the Consumed Capacity parameters has the same value as theSubscribed Capacity parameter as the entirety of the subscribed disk space is fully allocated inthe storage pool

The Consumed Capacity Percentage parameter is the most critical one as a storage pool usagenearing 100 means that SAN administrators will not be able to create new LUNs in the storagepool By default no alarm or warning threshold is set on this parameter as the fullness of a storagepool may be a normal situation However you can set alert thresholds on this parameter as it fitsyour needs

57Reporting a Disk Space Consumption

Managing Baselines and KeyPerformance IndicatorsIn order to facilitate the detection of abnormalities on your monitored environment BMCProactiveNet calculates baselines per parameter (metrics or attributes) based on values collectedover a specified period of time to determine a normal operating range When the collected values forthese parameters are out of range an alert is triggered

Some parameters are identified by default as Key Performance Indicators and therefore automaticallyincluded in the base lining calculation

42Managing Baselines and Key PerformanceIndicators

BMC Performance Manager Express for EMC Disk Arrays

Version 2001

Managing baselines

The baseline is the expected normal operating range for a metric or attribute of a monitor

The baseline is calculated by collecting the values for a monitorrsquos attributes and metrics over aspecified time period and establishing a low baseline value (consisting of the 10th percentile of all thevalues for a given time period) and a high baseline value (consisting of the 90th percentile of all thevalues for a given time period) taking a weighted average of these values over time A higher weightis given to the latest data being factored into the baseline average The accuracy of the baselineimproves over time

Requirements for baseline generation

For baselines to be generated for an attribute that abnormality threshold means that the thresholdexists and is not suppressed Additionally if the Key Performance Indicator (KPI) mode is active only those attributes that have anactive abnormality threshold and are also KPI attributes will have baselines generated for them

Absolute thresholds (with outside baseline) or signature thresholds do not satisfy these requirements

Managing Key Performance Indicators

The KPI attribute of a parameter can be activated or deactivated manually through the BMCProactiveNet Administration Console In this PM some parameters or attributes have beendesignated as important indicators of performance (KPIs) We do not recommend that these defaultsettings are modified

However advanced users may activate or deactivate KPIs from the BMC ProactiveNet AdministrationConsole

To add or remove Key Performance Indicator (KPI) attributes for amonitor type

1 In the Administration Console from the menu bar choose Tools gt KPI AdministrationThe KPI Administration dialog box is displayed

2 From the Monitor Type list choose the monitor type for which you want to add or remove KPIattributes A list of attributes for the selected monitor type is displayed

3 In the KPI column for the attributes that you want to add or remove as Key PerformanceIndicators

middot select the KPI check box to add the corresponding attribute as a KPI

middot deselect the KPI check box to remove the corresponding attribute from the KPIs for thatmonitor type

For complete and detailed information on this procedure please refer to the BMC ProactiveNet documentation availablefrom BMC Web site

BMC Performance Manager Express for EMC Disk Arrays is a Performance Manager specifically designedfor BMC Portal consequently it uses the same common features and procedures of BMCreg Portal Thisdocument assumes that the user knows how to use the Portal and therefore explains procedures onlyrelated to BMC Performance Manager Express for EMC Disk Arrays and not on how to add ElementsElement Profiles etc Please refer to the BMC Portal documentation for details on how to use the Portal

Checking Available Spare Disks

To avoid any loss of critical data it is essential for a disk array to always maintain a pool of sparedisks that can replace the faulty disk when a disk failure occurs A disk array without any left sparedisk will not be able to keep the level of data safety and performance in case of a disk failure

The Spare Disk Count parameter of the SEN_EMC_ARRAY class reports the number of spare disksavailable for each disk array monitored with the solution By default a warning is triggered when nospare disk is available (Spare Disk Count is set to zero)

Verifying the Number of Available Spare Disks in Your EMC Disk Arrays

49Checking Available Spare Disks

BMC Performance Manager Express for EMC Disk Arrays

Version 2001

1 Select an element group in the tree view (the main Infrastructure group for example)

2 Click the Reports tab Create a report for the last 24 hours bottom 50 values of the Array|Spare Disk Count parameter of the EMC Disk Arrays application class for the BMC PerformanceManager Express for EMC Disk Arrays by Sentry Software solution

Detecting OversubscriptionSituations (Thin Provisioning)We call an oversubscription situation when

1 The storage pool is configured for thin provisioning (ldquothin storage poolrdquo)

2 The storage pool is oversubscribed ie the total disk space visible to the hosts (subscribers) isgreater than its actual capacity (this situation is normal for a thin pool since it is its very purpose)

3 The storage pool actual consumed capacity is nearing 100

Such situation is highly critical because the inability to allocate additional space to a LUN whenrequested by the subscriber host will lead to catastrophic data loss and corruption

When the conditions described above are met the solution sets the Oversubscription Situationparameter to 1 automatically raising a warning By default the warning for OversubscriptionSituation is issued when the Consumed Capacity Percentage parameter goes above 100 Thisthreshold can be configured in the input properties of the solution

50Detecting Oversubscription Situations (ThinProvisioning)

BMC Performance Manager Express for EMC Disk Arrays

Version 2001

Configuring Oversubscription Threshold

1 Click the EMC Disk Arrays icon and then the Configure tab

2 Edit the Oversubscription Situation Threshold () property to the appropriate value Whenthe Oversubscription Situation parameter triggers a warning it is highly recommended thatthe SAN administrators add capacity to the storage pool as soon as possible

Diagnosing Slow LUNs

If a system administrator complains that his servers are experiencing slow IOs performance and thatit is caused by the SAN you may want to verify the actual response time of the LUNs the server isrelying on

The Response Time parameter of the SEN_EMC_VOLUME class represents the average time it tookto complete the read and write operations on the LUN during the collection interval Typically theaverage response time is below 10 milliseconds You may also want to compare this value to theresponse time of the other LUNs to see whether one server is really getting worse IO performancethan another

Volume - Response Time Parameter

If the response time is low you will need to check the amount of data that is written and read onthis LUN The bad performance may simply be due to an abnormally large amount of data to processOtherwise the problem is maybe between the disk array and the server in the fiber links

51Enabling the Debug Mode

BMC Performance Manager Express for EMC Disk Arrays

Version 2001

Enabling the Debug Mode

By default BMC Performance Manager Express for EMC Disk Arrays sends only the most criticalinformation warning and error messages to the Application Collection Status parameter Mostoften this information is accurate enough to ensure that BMC Performance Manager Express for EMCDisk Arrays is functioning properly If you encounter an issue and wish to report it to customersupport you will be asked to enable the Debug Mode and provide the debug output to the supportteam

1 In the Configure tab gt under Tasks click Elements

2 Select the Element whose debug output you require and click Edit

3 Scroll down to Application Classes gt click the Application class for which you want toenable the debug mode gt click Edit

4 Select Yes from the drop-down Debug Mode list gt SaveBy default BMC Performance Manager Express for EMC Disk Arrays sends its debug output to RSM_HOMERSM(xx)serverrsmlogsen_debuglog

5 Wait for 15 minutes and then disable the debug mode by selecting No

6 Send the debug file to the support team

Pay attention to the file size -the debug output of BMC Performance Manager Express for EMC Disk Arrays could bevery large if enabled for several days

Identifying the Hosts that canAccess a LUNIn most SAN configurations each LUN belongs to a storage group whose host members are the onlyones authorized to access the LUN This is called LUN masking For each LUN the solution displaysits WWN the storage group to which it belongs to as well as the hosts member of this group Inmost cases identifying the storage group of a LUN is sufficient to recognize the server that is usingit

52Identifying LUNs not Owned by their Normal(Default) Storage Processor

BMC Performance Manager Express for EMC Disk Arrays

Version 2001

Identifying LUNs not Owned bytheir Normal (Default) StorageProcessorThe Owning Storage Processor parameter reports the name of the controller that handles IOsfor each LUN If a LUN is not currently handled by its normal (default) storage processors the nameof the default controller will be indicated as SP_B (default SP_A)rdquo

To identify LUNs that are not owned by their normal storage processor you simply need to list the Volume objects where the Owning Storage Processor parameter contains the string Default

Identifying Most Busy LUNs

To identify the LUNs that generate the most traffic on the disk array use the Read Byte Rate andWrite Byte Rate parameters of the LUN class that expose the data throughput for each LUN Usethese parameters to report on the total data traffic (per hour or per day) on each LUN in GB

To make sure that traffic is displayed cumulatively per hour select a time window of at least 12 hours in the graphwindow select at least 7 days to visualize per day cumulative data

1 In the Status tab click the Volume for which you need to check the LUNs activity then expandthe LUNs object to display the ReadWrite Byte Rate parameters

BMC Performance Manager Express for EMC Disk Arrays

Version 2001

View ing a LUNs ReadW rite Byte Rate as a graph

Identifying a Storage Processor(Controllers) OverloadTo visualize the activity of a controller in an EMC disk array use the Processor Utilizationparameter of the SEN_EMC_CONTROLLER class A warning is issued when the processor utilizationgoes too high which means that the controllers cannot keep up with the load on the disk array It isthen important to identify what is overloading the controllers

The Response Time parameter of the SEN_EMC_CONTROLLER class represents the average time ittook the controller to process the read and write requests of the hosts The higher the ResponseTime goes the slower IOs the servers will get By default the solution triggers a warning when thecontroller takes more than 10 milliseconds on average to complete the IO requests and an alarmwhen the response time reaches 100 milliseconds

Monitoring the Efficiency of theCaching MechanismEach controller in an EMC disk array can be configured to use a specified amount of memory tocache the read andor write operations The solution reports the amount of memory configured byeach controller for the read and write operations

The Write Flush Byte Rate represents the rate in MBsec at which data is committed to the disk(ie physically written) This value is to be compared with the Write Byte Rate of the disk array

55Monitoring the Efficiency of the CachingMechanism

BMC Performance Manager Express for EMC Disk Arrays

Version 2001

Comparing W rite Flush Byte Rate w ith W rite Byte Rate

The Cache Dirty Pages Percentage parameter represents the amount in percentage of the writecache that has been modified by host write operations and not yet flushed to the disks Reaching100 means that write case is too small and cannot handle the flow of write operations

Checking the Cache Dirty Pages Percentage

Reclaiming Space of Unmapped(Unused) LUNsOver time as servers connected to a SAN get decommissioned administrators find an increasingnumber of unmapped LUNs or volumes that are no longer used by any server These LUNs whileunused still occupy disk space in the disk array Being able to identify such unmapped LUNs andreclaim the disk space uselessly consumed by these LUNs will help administrators avoid unnecessaryupgrades and extensions of their disk arrays

56Reporting a Disk Space Consumption

BMC Performance Manager Express for EMC Disk Arrays

Version 2001

Reporting a Disk SpaceConsumptionMaking sure that a disk array has enough remaining disk space available is critical for severalreasons

middot SAN administrators want to make sure to be able to provision disk space for new servers whenrequested as quickly as possible

middot The disk array itself may need additional disk space for specific features to work properly likeautomatic snapshots mirroring etc

middot If thin provisioning is used the remaining disk space becomes dramatically critical since theinability to allocate additional space to a LUN when requested by the subscriber host will lead tocatastrophic data loss and corruption

The disk space used is permanently monitored for each storage pool The Subscribed Capacityparameter of the Pool class represents the amount of disk space that has been made available tothe subscriber hosts or in other words the amount of disk space that is seen by the serversconnected to disk array

The Consumed Capacity parameter of the SEN_EMC_STORAGEPOOLS class represents the actualspace usage in the storage pool For thin pools (when thin provisioning is enabled on the disk array)this value is normally lower than the Subscribed Capacity as it is the main purpose of thinprovisioning For traditional pools the Consumed Capacity parameters has the same value as theSubscribed Capacity parameter as the entirety of the subscribed disk space is fully allocated inthe storage pool

The Consumed Capacity Percentage parameter is the most critical one as a storage pool usagenearing 100 means that SAN administrators will not be able to create new LUNs in the storagepool By default no alarm or warning threshold is set on this parameter as the fullness of a storagepool may be a normal situation However you can set alert thresholds on this parameter as it fitsyour needs

Managing Baselines and KeyPerformance IndicatorsIn order to facilitate the detection of abnormalities on your monitored environment BMCProactiveNet calculates baselines per parameter (metrics or attributes) based on values collectedover a specified period of time to determine a normal operating range When the collected values forthese parameters are out of range an alert is triggered

Some parameters are identified by default as Key Performance Indicators and therefore automaticallyincluded in the base lining calculation

42Managing Baselines and Key PerformanceIndicators

BMC Performance Manager Express for EMC Disk Arrays

Version 2001

Managing baselines

The baseline is the expected normal operating range for a metric or attribute of a monitor

The baseline is calculated by collecting the values for a monitorrsquos attributes and metrics over aspecified time period and establishing a low baseline value (consisting of the 10th percentile of all thevalues for a given time period) and a high baseline value (consisting of the 90th percentile of all thevalues for a given time period) taking a weighted average of these values over time A higher weightis given to the latest data being factored into the baseline average The accuracy of the baselineimproves over time

Requirements for baseline generation

For baselines to be generated for an attribute that abnormality threshold means that the thresholdexists and is not suppressed Additionally if the Key Performance Indicator (KPI) mode is active only those attributes that have anactive abnormality threshold and are also KPI attributes will have baselines generated for them

Absolute thresholds (with outside baseline) or signature thresholds do not satisfy these requirements

Managing Key Performance Indicators

The KPI attribute of a parameter can be activated or deactivated manually through the BMCProactiveNet Administration Console In this PM some parameters or attributes have beendesignated as important indicators of performance (KPIs) We do not recommend that these defaultsettings are modified

However advanced users may activate or deactivate KPIs from the BMC ProactiveNet AdministrationConsole

To add or remove Key Performance Indicator (KPI) attributes for amonitor type

1 In the Administration Console from the menu bar choose Tools gt KPI AdministrationThe KPI Administration dialog box is displayed

2 From the Monitor Type list choose the monitor type for which you want to add or remove KPIattributes A list of attributes for the selected monitor type is displayed

3 In the KPI column for the attributes that you want to add or remove as Key PerformanceIndicators

middot select the KPI check box to add the corresponding attribute as a KPI

middot deselect the KPI check box to remove the corresponding attribute from the KPIs for thatmonitor type

For complete and detailed information on this procedure please refer to the BMC ProactiveNet documentation availablefrom BMC Web site

BMC Performance Manager Express for EMC Disk Arrays monitors all of the performance metrics andusage statistics of your EMC disk arrays such as file disk space usage storage controller utilizationIOs on the diskscontrollersvolumes etc It continuously monitors the activity of each array and isalso able to build reports on past utilization statistics

To setup a complete monitoring of the array we strongly recommend you to also use BMCPerformance Manager Express for Hardware that covers all the physical aspect of the EMC diskarrays (status of the disks ports temperature power supplies power consumption etc)

This chapter explains how to use each monitoring tool ie a separate application class within theBMC Performance Manager Express for EMC Disk Arrays by Sentry Software solution

BMC Performance Manager Express for EMC Disk Arrays is a Performance Manager specifically designedfor BMC Portal consequently it uses the same common features and procedures of BMCreg Portal Thisdocument assumes that the user knows how to use the Portal and therefore explains procedures onlyrelated to BMC Performance Manager Express for EMC Disk Arrays and not on how to add ElementsElement Profiles etc Please refer to the BMC Portal documentation for details on how to use the Portal

Checking Available Spare Disks

To avoid any loss of critical data it is essential for a disk array to always maintain a pool of sparedisks that can replace the faulty disk when a disk failure occurs A disk array without any left sparedisk will not be able to keep the level of data safety and performance in case of a disk failure

The Spare Disk Count parameter of the SEN_EMC_ARRAY class reports the number of spare disksavailable for each disk array monitored with the solution By default a warning is triggered when nospare disk is available (Spare Disk Count is set to zero)

Verifying the Number of Available Spare Disks in Your EMC Disk Arrays

49Checking Available Spare Disks

BMC Performance Manager Express for EMC Disk Arrays

Version 2001

1 Select an element group in the tree view (the main Infrastructure group for example)

2 Click the Reports tab Create a report for the last 24 hours bottom 50 values of the Array|Spare Disk Count parameter of the EMC Disk Arrays application class for the BMC PerformanceManager Express for EMC Disk Arrays by Sentry Software solution

Detecting OversubscriptionSituations (Thin Provisioning)We call an oversubscription situation when

1 The storage pool is configured for thin provisioning (ldquothin storage poolrdquo)

2 The storage pool is oversubscribed ie the total disk space visible to the hosts (subscribers) isgreater than its actual capacity (this situation is normal for a thin pool since it is its very purpose)

3 The storage pool actual consumed capacity is nearing 100

Such situation is highly critical because the inability to allocate additional space to a LUN whenrequested by the subscriber host will lead to catastrophic data loss and corruption

When the conditions described above are met the solution sets the Oversubscription Situationparameter to 1 automatically raising a warning By default the warning for OversubscriptionSituation is issued when the Consumed Capacity Percentage parameter goes above 100 Thisthreshold can be configured in the input properties of the solution

50Detecting Oversubscription Situations (ThinProvisioning)

BMC Performance Manager Express for EMC Disk Arrays

Version 2001

Configuring Oversubscription Threshold

1 Click the EMC Disk Arrays icon and then the Configure tab

2 Edit the Oversubscription Situation Threshold () property to the appropriate value Whenthe Oversubscription Situation parameter triggers a warning it is highly recommended thatthe SAN administrators add capacity to the storage pool as soon as possible

Diagnosing Slow LUNs

If a system administrator complains that his servers are experiencing slow IOs performance and thatit is caused by the SAN you may want to verify the actual response time of the LUNs the server isrelying on

The Response Time parameter of the SEN_EMC_VOLUME class represents the average time it tookto complete the read and write operations on the LUN during the collection interval Typically theaverage response time is below 10 milliseconds You may also want to compare this value to theresponse time of the other LUNs to see whether one server is really getting worse IO performancethan another

Volume - Response Time Parameter

If the response time is low you will need to check the amount of data that is written and read onthis LUN The bad performance may simply be due to an abnormally large amount of data to processOtherwise the problem is maybe between the disk array and the server in the fiber links

51Enabling the Debug Mode

BMC Performance Manager Express for EMC Disk Arrays

Version 2001

Enabling the Debug Mode

By default BMC Performance Manager Express for EMC Disk Arrays sends only the most criticalinformation warning and error messages to the Application Collection Status parameter Mostoften this information is accurate enough to ensure that BMC Performance Manager Express for EMCDisk Arrays is functioning properly If you encounter an issue and wish to report it to customersupport you will be asked to enable the Debug Mode and provide the debug output to the supportteam

1 In the Configure tab gt under Tasks click Elements

2 Select the Element whose debug output you require and click Edit

3 Scroll down to Application Classes gt click the Application class for which you want toenable the debug mode gt click Edit

4 Select Yes from the drop-down Debug Mode list gt SaveBy default BMC Performance Manager Express for EMC Disk Arrays sends its debug output to RSM_HOMERSM(xx)serverrsmlogsen_debuglog

5 Wait for 15 minutes and then disable the debug mode by selecting No

6 Send the debug file to the support team

Pay attention to the file size -the debug output of BMC Performance Manager Express for EMC Disk Arrays could bevery large if enabled for several days

Identifying the Hosts that canAccess a LUNIn most SAN configurations each LUN belongs to a storage group whose host members are the onlyones authorized to access the LUN This is called LUN masking For each LUN the solution displaysits WWN the storage group to which it belongs to as well as the hosts member of this group Inmost cases identifying the storage group of a LUN is sufficient to recognize the server that is usingit

52Identifying LUNs not Owned by their Normal(Default) Storage Processor

BMC Performance Manager Express for EMC Disk Arrays

Version 2001

Identifying LUNs not Owned bytheir Normal (Default) StorageProcessorThe Owning Storage Processor parameter reports the name of the controller that handles IOsfor each LUN If a LUN is not currently handled by its normal (default) storage processors the nameof the default controller will be indicated as SP_B (default SP_A)rdquo

To identify LUNs that are not owned by their normal storage processor you simply need to list the Volume objects where the Owning Storage Processor parameter contains the string Default

Identifying Most Busy LUNs

To identify the LUNs that generate the most traffic on the disk array use the Read Byte Rate andWrite Byte Rate parameters of the LUN class that expose the data throughput for each LUN Usethese parameters to report on the total data traffic (per hour or per day) on each LUN in GB

To make sure that traffic is displayed cumulatively per hour select a time window of at least 12 hours in the graphwindow select at least 7 days to visualize per day cumulative data

1 In the Status tab click the Volume for which you need to check the LUNs activity then expandthe LUNs object to display the ReadWrite Byte Rate parameters

Version 2001

View ing a LUNs ReadW rite Byte Rate as a graph

Identifying a Storage Processor(Controllers) OverloadTo visualize the activity of a controller in an EMC disk array use the Processor Utilizationparameter of the SEN_EMC_CONTROLLER class A warning is issued when the processor utilizationgoes too high which means that the controllers cannot keep up with the load on the disk array It isthen important to identify what is overloading the controllers

The Response Time parameter of the SEN_EMC_CONTROLLER class represents the average time ittook the controller to process the read and write requests of the hosts The higher the ResponseTime goes the slower IOs the servers will get By default the solution triggers a warning when thecontroller takes more than 10 milliseconds on average to complete the IO requests and an alarmwhen the response time reaches 100 milliseconds

Monitoring the Efficiency of theCaching MechanismEach controller in an EMC disk array can be configured to use a specified amount of memory tocache the read andor write operations The solution reports the amount of memory configured byeach controller for the read and write operations

The Write Flush Byte Rate represents the rate in MBsec at which data is committed to the disk(ie physically written) This value is to be compared with the Write Byte Rate of the disk array

55Monitoring the Efficiency of the CachingMechanism

BMC Performance Manager Express for EMC Disk Arrays

Version 2001

Comparing W rite Flush Byte Rate w ith W rite Byte Rate

The Cache Dirty Pages Percentage parameter represents the amount in percentage of the writecache that has been modified by host write operations and not yet flushed to the disks Reaching100 means that write case is too small and cannot handle the flow of write operations

Checking the Cache Dirty Pages Percentage

Reclaiming Space of Unmapped(Unused) LUNsOver time as servers connected to a SAN get decommissioned administrators find an increasingnumber of unmapped LUNs or volumes that are no longer used by any server These LUNs whileunused still occupy disk space in the disk array Being able to identify such unmapped LUNs andreclaim the disk space uselessly consumed by these LUNs will help administrators avoid unnecessaryupgrades and extensions of their disk arrays

56Reporting a Disk Space Consumption

BMC Performance Manager Express for EMC Disk Arrays

Version 2001

Reporting a Disk SpaceConsumptionMaking sure that a disk array has enough remaining disk space available is critical for severalreasons

middot SAN administrators want to make sure to be able to provision disk space for new servers whenrequested as quickly as possible

middot The disk array itself may need additional disk space for specific features to work properly likeautomatic snapshots mirroring etc

middot If thin provisioning is used the remaining disk space becomes dramatically critical since theinability to allocate additional space to a LUN when requested by the subscriber host will lead tocatastrophic data loss and corruption

The disk space used is permanently monitored for each storage pool The Subscribed Capacityparameter of the Pool class represents the amount of disk space that has been made available tothe subscriber hosts or in other words the amount of disk space that is seen by the serversconnected to disk array

The Consumed Capacity parameter of the SEN_EMC_STORAGEPOOLS class represents the actualspace usage in the storage pool For thin pools (when thin provisioning is enabled on the disk array)this value is normally lower than the Subscribed Capacity as it is the main purpose of thinprovisioning For traditional pools the Consumed Capacity parameters has the same value as theSubscribed Capacity parameter as the entirety of the subscribed disk space is fully allocated inthe storage pool

The Consumed Capacity Percentage parameter is the most critical one as a storage pool usagenearing 100 means that SAN administrators will not be able to create new LUNs in the storagepool By default no alarm or warning threshold is set on this parameter as the fullness of a storagepool may be a normal situation However you can set alert thresholds on this parameter as it fitsyour needs

Managing Baselines and KeyPerformance IndicatorsIn order to facilitate the detection of abnormalities on your monitored environment BMCProactiveNet calculates baselines per parameter (metrics or attributes) based on values collectedover a specified period of time to determine a normal operating range When the collected values forthese parameters are out of range an alert is triggered

Some parameters are identified by default as Key Performance Indicators and therefore automaticallyincluded in the base lining calculation

42Managing Baselines and Key PerformanceIndicators

BMC Performance Manager Express for EMC Disk Arrays

Version 2001

Managing baselines

The baseline is the expected normal operating range for a metric or attribute of a monitor

The baseline is calculated by collecting the values for a monitorrsquos attributes and metrics over aspecified time period and establishing a low baseline value (consisting of the 10th percentile of all thevalues for a given time period) and a high baseline value (consisting of the 90th percentile of all thevalues for a given time period) taking a weighted average of these values over time A higher weightis given to the latest data being factored into the baseline average The accuracy of the baselineimproves over time

Requirements for baseline generation

For baselines to be generated for an attribute that abnormality threshold means that the thresholdexists and is not suppressed Additionally if the Key Performance Indicator (KPI) mode is active only those attributes that have anactive abnormality threshold and are also KPI attributes will have baselines generated for them

Absolute thresholds (with outside baseline) or signature thresholds do not satisfy these requirements

Managing Key Performance Indicators

The KPI attribute of a parameter can be activated or deactivated manually through the BMCProactiveNet Administration Console In this PM some parameters or attributes have beendesignated as important indicators of performance (KPIs) We do not recommend that these defaultsettings are modified

However advanced users may activate or deactivate KPIs from the BMC ProactiveNet AdministrationConsole

To add or remove Key Performance Indicator (KPI) attributes for amonitor type

1 In the Administration Console from the menu bar choose Tools gt KPI AdministrationThe KPI Administration dialog box is displayed

2 From the Monitor Type list choose the monitor type for which you want to add or remove KPIattributes A list of attributes for the selected monitor type is displayed

3 In the KPI column for the attributes that you want to add or remove as Key PerformanceIndicators

middot select the KPI check box to add the corresponding attribute as a KPI

middot deselect the KPI check box to remove the corresponding attribute from the KPIs for thatmonitor type

For complete and detailed information on this procedure please refer to the BMC ProactiveNet documentation availablefrom BMC Web site

BMC Performance Manager Express for EMC Disk Arrays

Version 2001

BMC Performance Manager Express for EMC Disk Arrays monitors all of the performance metrics andusage statistics of your EMC disk arrays such as file disk space usage storage controller utilizationIOs on the diskscontrollersvolumes etc It continuously monitors the activity of each array and isalso able to build reports on past utilization statistics

To setup a complete monitoring of the array we strongly recommend you to also use BMCPerformance Manager Express for Hardware that covers all the physical aspect of the EMC diskarrays (status of the disks ports temperature power supplies power consumption etc)

This chapter explains how to use each monitoring tool ie a separate application class within theBMC Performance Manager Express for EMC Disk Arrays by Sentry Software solution

BMC Performance Manager Express for EMC Disk Arrays is a Performance Manager specifically designedfor BMC Portal consequently it uses the same common features and procedures of BMCreg Portal Thisdocument assumes that the user knows how to use the Portal and therefore explains procedures onlyrelated to BMC Performance Manager Express for EMC Disk Arrays and not on how to add ElementsElement Profiles etc Please refer to the BMC Portal documentation for details on how to use the Portal

Checking Available Spare Disks

To avoid any loss of critical data it is essential for a disk array to always maintain a pool of sparedisks that can replace the faulty disk when a disk failure occurs A disk array without any left sparedisk will not be able to keep the level of data safety and performance in case of a disk failure

The Spare Disk Count parameter of the SEN_EMC_ARRAY class reports the number of spare disksavailable for each disk array monitored with the solution By default a warning is triggered when nospare disk is available (Spare Disk Count is set to zero)

Verifying the Number of Available Spare Disks in Your EMC Disk Arrays

49Checking Available Spare Disks

BMC Performance Manager Express for EMC Disk Arrays

Version 2001

1 Select an element group in the tree view (the main Infrastructure group for example)

2 Click the Reports tab Create a report for the last 24 hours bottom 50 values of the Array|Spare Disk Count parameter of the EMC Disk Arrays application class for the BMC PerformanceManager Express for EMC Disk Arrays by Sentry Software solution

Detecting OversubscriptionSituations (Thin Provisioning)We call an oversubscription situation when

1 The storage pool is configured for thin provisioning (ldquothin storage poolrdquo)

2 The storage pool is oversubscribed ie the total disk space visible to the hosts (subscribers) isgreater than its actual capacity (this situation is normal for a thin pool since it is its very purpose)

3 The storage pool actual consumed capacity is nearing 100

Such situation is highly critical because the inability to allocate additional space to a LUN whenrequested by the subscriber host will lead to catastrophic data loss and corruption

When the conditions described above are met the solution sets the Oversubscription Situationparameter to 1 automatically raising a warning By default the warning for OversubscriptionSituation is issued when the Consumed Capacity Percentage parameter goes above 100 Thisthreshold can be configured in the input properties of the solution

50Detecting Oversubscription Situations (ThinProvisioning)

BMC Performance Manager Express for EMC Disk Arrays

Version 2001

Configuring Oversubscription Threshold

1 Click the EMC Disk Arrays icon and then the Configure tab

2 Edit the Oversubscription Situation Threshold () property to the appropriate value Whenthe Oversubscription Situation parameter triggers a warning it is highly recommended thatthe SAN administrators add capacity to the storage pool as soon as possible

Diagnosing Slow LUNs

If a system administrator complains that his servers are experiencing slow IOs performance and thatit is caused by the SAN you may want to verify the actual response time of the LUNs the server isrelying on

The Response Time parameter of the SEN_EMC_VOLUME class represents the average time it tookto complete the read and write operations on the LUN during the collection interval Typically theaverage response time is below 10 milliseconds You may also want to compare this value to theresponse time of the other LUNs to see whether one server is really getting worse IO performancethan another

Volume - Response Time Parameter

If the response time is low you will need to check the amount of data that is written and read onthis LUN The bad performance may simply be due to an abnormally large amount of data to processOtherwise the problem is maybe between the disk array and the server in the fiber links

51Enabling the Debug Mode

BMC Performance Manager Express for EMC Disk Arrays

Version 2001

Enabling the Debug Mode

By default BMC Performance Manager Express for EMC Disk Arrays sends only the most criticalinformation warning and error messages to the Application Collection Status parameter Mostoften this information is accurate enough to ensure that BMC Performance Manager Express for EMCDisk Arrays is functioning properly If you encounter an issue and wish to report it to customersupport you will be asked to enable the Debug Mode and provide the debug output to the supportteam

1 In the Configure tab gt under Tasks click Elements

2 Select the Element whose debug output you require and click Edit

3 Scroll down to Application Classes gt click the Application class for which you want toenable the debug mode gt click Edit

4 Select Yes from the drop-down Debug Mode list gt SaveBy default BMC Performance Manager Express for EMC Disk Arrays sends its debug output to RSM_HOMERSM(xx)serverrsmlogsen_debuglog

5 Wait for 15 minutes and then disable the debug mode by selecting No

6 Send the debug file to the support team

Pay attention to the file size -the debug output of BMC Performance Manager Express for EMC Disk Arrays could bevery large if enabled for several days

Identifying the Hosts that canAccess a LUNIn most SAN configurations each LUN belongs to a storage group whose host members are the onlyones authorized to access the LUN This is called LUN masking For each LUN the solution displaysits WWN the storage group to which it belongs to as well as the hosts member of this group Inmost cases identifying the storage group of a LUN is sufficient to recognize the server that is usingit

52Identifying LUNs not Owned by their Normal(Default) Storage Processor

BMC Performance Manager Express for EMC Disk Arrays

Version 2001

Identifying LUNs not Owned bytheir Normal (Default) StorageProcessorThe Owning Storage Processor parameter reports the name of the controller that handles IOsfor each LUN If a LUN is not currently handled by its normal (default) storage processors the nameof the default controller will be indicated as SP_B (default SP_A)rdquo

To identify LUNs that are not owned by their normal storage processor you simply need to list the Volume objects where the Owning Storage Processor parameter contains the string Default

Identifying Most Busy LUNs

To identify the LUNs that generate the most traffic on the disk array use the Read Byte Rate andWrite Byte Rate parameters of the LUN class that expose the data throughput for each LUN Usethese parameters to report on the total data traffic (per hour or per day) on each LUN in GB

To make sure that traffic is displayed cumulatively per hour select a time window of at least 12 hours in the graphwindow select at least 7 days to visualize per day cumulative data

1 In the Status tab click the Volume for which you need to check the LUNs activity then expandthe LUNs object to display the ReadWrite Byte Rate parameters

Version 2001

View ing a LUNs ReadW rite Byte Rate as a graph

Identifying a Storage Processor(Controllers) OverloadTo visualize the activity of a controller in an EMC disk array use the Processor Utilizationparameter of the SEN_EMC_CONTROLLER class A warning is issued when the processor utilizationgoes too high which means that the controllers cannot keep up with the load on the disk array It isthen important to identify what is overloading the controllers

The Response Time parameter of the SEN_EMC_CONTROLLER class represents the average time ittook the controller to process the read and write requests of the hosts The higher the ResponseTime goes the slower IOs the servers will get By default the solution triggers a warning when thecontroller takes more than 10 milliseconds on average to complete the IO requests and an alarmwhen the response time reaches 100 milliseconds

Monitoring the Efficiency of theCaching MechanismEach controller in an EMC disk array can be configured to use a specified amount of memory tocache the read andor write operations The solution reports the amount of memory configured byeach controller for the read and write operations

The Write Flush Byte Rate represents the rate in MBsec at which data is committed to the disk(ie physically written) This value is to be compared with the Write Byte Rate of the disk array

55Monitoring the Efficiency of the CachingMechanism

BMC Performance Manager Express for EMC Disk Arrays

Version 2001

Comparing W rite Flush Byte Rate w ith W rite Byte Rate

The Cache Dirty Pages Percentage parameter represents the amount in percentage of the writecache that has been modified by host write operations and not yet flushed to the disks Reaching100 means that write case is too small and cannot handle the flow of write operations

Checking the Cache Dirty Pages Percentage

Reclaiming Space of Unmapped(Unused) LUNsOver time as servers connected to a SAN get decommissioned administrators find an increasingnumber of unmapped LUNs or volumes that are no longer used by any server These LUNs whileunused still occupy disk space in the disk array Being able to identify such unmapped LUNs andreclaim the disk space uselessly consumed by these LUNs will help administrators avoid unnecessaryupgrades and extensions of their disk arrays

56Reporting a Disk Space Consumption

BMC Performance Manager Express for EMC Disk Arrays

Version 2001

Reporting a Disk SpaceConsumptionMaking sure that a disk array has enough remaining disk space available is critical for severalreasons

middot SAN administrators want to make sure to be able to provision disk space for new servers whenrequested as quickly as possible

middot The disk array itself may need additional disk space for specific features to work properly likeautomatic snapshots mirroring etc

middot If thin provisioning is used the remaining disk space becomes dramatically critical since theinability to allocate additional space to a LUN when requested by the subscriber host will lead tocatastrophic data loss and corruption

The disk space used is permanently monitored for each storage pool The Subscribed Capacityparameter of the Pool class represents the amount of disk space that has been made available tothe subscriber hosts or in other words the amount of disk space that is seen by the serversconnected to disk array

The Consumed Capacity parameter of the SEN_EMC_STORAGEPOOLS class represents the actualspace usage in the storage pool For thin pools (when thin provisioning is enabled on the disk array)this value is normally lower than the Subscribed Capacity as it is the main purpose of thinprovisioning For traditional pools the Consumed Capacity parameters has the same value as theSubscribed Capacity parameter as the entirety of the subscribed disk space is fully allocated inthe storage pool

The Consumed Capacity Percentage parameter is the most critical one as a storage pool usagenearing 100 means that SAN administrators will not be able to create new LUNs in the storagepool By default no alarm or warning threshold is set on this parameter as the fullness of a storagepool may be a normal situation However you can set alert thresholds on this parameter as it fitsyour needs

We strongly recommend that you create a specific adapter for each PM you need to integrate into BMCProactiveNet to enable the update of a single PM independently

Once created and imported the Adapter will be displayed in the Devices folder of the BMCProactiveNet Operations Console

Managing Baselines and KeyPerformance IndicatorsIn order to facilitate the detection of abnormalities on your monitored environment BMCProactiveNet calculates baselines per parameter (metrics or attributes) based on values collectedover a specified period of time to determine a normal operating range When the collected values forthese parameters are out of range an alert is triggered

Some parameters are identified by default as Key Performance Indicators and therefore automaticallyincluded in the base lining calculation

42Managing Baselines and Key PerformanceIndicators

BMC Performance Manager Express for EMC Disk Arrays

Version 2001

Managing baselines

The baseline is the expected normal operating range for a metric or attribute of a monitor

The baseline is calculated by collecting the values for a monitorrsquos attributes and metrics over aspecified time period and establishing a low baseline value (consisting of the 10th percentile of all thevalues for a given time period) and a high baseline value (consisting of the 90th percentile of all thevalues for a given time period) taking a weighted average of these values over time A higher weightis given to the latest data being factored into the baseline average The accuracy of the baselineimproves over time

Requirements for baseline generation

For baselines to be generated for an attribute that abnormality threshold means that the thresholdexists and is not suppressed Additionally if the Key Performance Indicator (KPI) mode is active only those attributes that have anactive abnormality threshold and are also KPI attributes will have baselines generated for them

Absolute thresholds (with outside baseline) or signature thresholds do not satisfy these requirements

Managing Key Performance Indicators

The KPI attribute of a parameter can be activated or deactivated manually through the BMCProactiveNet Administration Console In this PM some parameters or attributes have beendesignated as important indicators of performance (KPIs) We do not recommend that these defaultsettings are modified

However advanced users may activate or deactivate KPIs from the BMC ProactiveNet AdministrationConsole

To add or remove Key Performance Indicator (KPI) attributes for amonitor type

1 In the Administration Console from the menu bar choose Tools gt KPI AdministrationThe KPI Administration dialog box is displayed

2 From the Monitor Type list choose the monitor type for which you want to add or remove KPIattributes A list of attributes for the selected monitor type is displayed

3 In the KPI column for the attributes that you want to add or remove as Key PerformanceIndicators

middot select the KPI check box to add the corresponding attribute as a KPI

middot deselect the KPI check box to remove the corresponding attribute from the KPIs for thatmonitor type

For complete and detailed information on this procedure please refer to the BMC ProactiveNet documentation availablefrom BMC Web site

BMC Performance Manager Express for EMC Disk Arrays

Version 2001

BMC Performance Manager Express for EMC Disk Arrays monitors all of the performance metrics andusage statistics of your EMC disk arrays such as file disk space usage storage controller utilizationIOs on the diskscontrollersvolumes etc It continuously monitors the activity of each array and isalso able to build reports on past utilization statistics

To setup a complete monitoring of the array we strongly recommend you to also use BMCPerformance Manager Express for Hardware that covers all the physical aspect of the EMC diskarrays (status of the disks ports temperature power supplies power consumption etc)

This chapter explains how to use each monitoring tool ie a separate application class within theBMC Performance Manager Express for EMC Disk Arrays by Sentry Software solution

BMC Performance Manager Express for EMC Disk Arrays is a Performance Manager specifically designedfor BMC Portal consequently it uses the same common features and procedures of BMCreg Portal Thisdocument assumes that the user knows how to use the Portal and therefore explains procedures onlyrelated to BMC Performance Manager Express for EMC Disk Arrays and not on how to add ElementsElement Profiles etc Please refer to the BMC Portal documentation for details on how to use the Portal

Checking Available Spare Disks

To avoid any loss of critical data it is essential for a disk array to always maintain a pool of sparedisks that can replace the faulty disk when a disk failure occurs A disk array without any left sparedisk will not be able to keep the level of data safety and performance in case of a disk failure

The Spare Disk Count parameter of the SEN_EMC_ARRAY class reports the number of spare disksavailable for each disk array monitored with the solution By default a warning is triggered when nospare disk is available (Spare Disk Count is set to zero)

Verifying the Number of Available Spare Disks in Your EMC Disk Arrays

49Checking Available Spare Disks

BMC Performance Manager Express for EMC Disk Arrays

Version 2001

1 Select an element group in the tree view (the main Infrastructure group for example)

2 Click the Reports tab Create a report for the last 24 hours bottom 50 values of the Array|Spare Disk Count parameter of the EMC Disk Arrays application class for the BMC PerformanceManager Express for EMC Disk Arrays by Sentry Software solution

Report ndash Available Spare Disks

Detecting OversubscriptionSituations (Thin Provisioning)We call an oversubscription situation when

1 The storage pool is configured for thin provisioning (ldquothin storage poolrdquo)

2 The storage pool is oversubscribed ie the total disk space visible to the hosts (subscribers) isgreater than its actual capacity (this situation is normal for a thin pool since it is its very purpose)

3 The storage pool actual consumed capacity is nearing 100

Such situation is highly critical because the inability to allocate additional space to a LUN whenrequested by the subscriber host will lead to catastrophic data loss and corruption

When the conditions described above are met the solution sets the Oversubscription Situationparameter to 1 automatically raising a warning By default the warning for OversubscriptionSituation is issued when the Consumed Capacity Percentage parameter goes above 100 Thisthreshold can be configured in the input properties of the solution

50Detecting Oversubscription Situations (ThinProvisioning)

BMC Performance Manager Express for EMC Disk Arrays

Version 2001

Configuring Oversubscription Threshold

1 Click the EMC Disk Arrays icon and then the Configure tab

2 Edit the Oversubscription Situation Threshold () property to the appropriate value Whenthe Oversubscription Situation parameter triggers a warning it is highly recommended thatthe SAN administrators add capacity to the storage pool as soon as possible

Diagnosing Slow LUNs

If a system administrator complains that his servers are experiencing slow IOs performance and thatit is caused by the SAN you may want to verify the actual response time of the LUNs the server isrelying on

The Response Time parameter of the SEN_EMC_VOLUME class represents the average time it tookto complete the read and write operations on the LUN during the collection interval Typically theaverage response time is below 10 milliseconds You may also want to compare this value to theresponse time of the other LUNs to see whether one server is really getting worse IO performancethan another

Volume - Response Time Parameter

If the response time is low you will need to check the amount of data that is written and read onthis LUN The bad performance may simply be due to an abnormally large amount of data to processOtherwise the problem is maybe between the disk array and the server in the fiber links

51Enabling the Debug Mode

BMC Performance Manager Express for EMC Disk Arrays

Version 2001

Enabling the Debug Mode

By default BMC Performance Manager Express for EMC Disk Arrays sends only the most criticalinformation warning and error messages to the Application Collection Status parameter Mostoften this information is accurate enough to ensure that BMC Performance Manager Express for EMCDisk Arrays is functioning properly If you encounter an issue and wish to report it to customersupport you will be asked to enable the Debug Mode and provide the debug output to the supportteam

1 In the Configure tab gt under Tasks click Elements

2 Select the Element whose debug output you require and click Edit

3 Scroll down to Application Classes gt click the Application class for which you want toenable the debug mode gt click Edit

4 Select Yes from the drop-down Debug Mode list gt SaveBy default BMC Performance Manager Express for EMC Disk Arrays sends its debug output to RSM_HOMERSM(xx)serverrsmlogsen_debuglog

5 Wait for 15 minutes and then disable the debug mode by selecting No

6 Send the debug file to the support team

Pay attention to the file size -the debug output of BMC Performance Manager Express for EMC Disk Arrays could bevery large if enabled for several days

Identifying the Hosts that canAccess a LUNIn most SAN configurations each LUN belongs to a storage group whose host members are the onlyones authorized to access the LUN This is called LUN masking For each LUN the solution displaysits WWN the storage group to which it belongs to as well as the hosts member of this group Inmost cases identifying the storage group of a LUN is sufficient to recognize the server that is usingit

52Identifying LUNs not Owned by their Normal(Default) Storage Processor

BMC Performance Manager Express for EMC Disk Arrays

Version 2001

Identifying LUNs not Owned bytheir Normal (Default) StorageProcessorThe Owning Storage Processor parameter reports the name of the controller that handles IOsfor each LUN If a LUN is not currently handled by its normal (default) storage processors the nameof the default controller will be indicated as SP_B (default SP_A)rdquo

To identify LUNs that are not owned by their normal storage processor you simply need to list the Volume objects where the Owning Storage Processor parameter contains the string Default

Identifying Most Busy LUNs

To identify the LUNs that generate the most traffic on the disk array use the Read Byte Rate andWrite Byte Rate parameters of the LUN class that expose the data throughput for each LUN Usethese parameters to report on the total data traffic (per hour or per day) on each LUN in GB

To make sure that traffic is displayed cumulatively per hour select a time window of at least 12 hours in the graphwindow select at least 7 days to visualize per day cumulative data

1 In the Status tab click the Volume for which you need to check the LUNs activity then expandthe LUNs object to display the ReadWrite Byte Rate parameters

53Identifying Most Busy LUNs

Version 2001

View ing a LUNs ReadW rite Byte Rate as a graph

Identifying a Storage Processor(Controllers) OverloadTo visualize the activity of a controller in an EMC disk array use the Processor Utilizationparameter of the SEN_EMC_CONTROLLER class A warning is issued when the processor utilizationgoes too high which means that the controllers cannot keep up with the load on the disk array It isthen important to identify what is overloading the controllers

The Response Time parameter of the SEN_EMC_CONTROLLER class represents the average time ittook the controller to process the read and write requests of the hosts The higher the ResponseTime goes the slower IOs the servers will get By default the solution triggers a warning when thecontroller takes more than 10 milliseconds on average to complete the IO requests and an alarmwhen the response time reaches 100 milliseconds

Monitoring the Efficiency of theCaching MechanismEach controller in an EMC disk array can be configured to use a specified amount of memory tocache the read andor write operations The solution reports the amount of memory configured byeach controller for the read and write operations

The Write Flush Byte Rate represents the rate in MBsec at which data is committed to the disk(ie physically written) This value is to be compared with the Write Byte Rate of the disk array

55Monitoring the Efficiency of the CachingMechanism

BMC Performance Manager Express for EMC Disk Arrays

Version 2001

Comparing W rite Flush Byte Rate w ith W rite Byte Rate

The Cache Dirty Pages Percentage parameter represents the amount in percentage of the writecache that has been modified by host write operations and not yet flushed to the disks Reaching100 means that write case is too small and cannot handle the flow of write operations

Checking the Cache Dirty Pages Percentage

Reclaiming Space of Unmapped(Unused) LUNsOver time as servers connected to a SAN get decommissioned administrators find an increasingnumber of unmapped LUNs or volumes that are no longer used by any server These LUNs whileunused still occupy disk space in the disk array Being able to identify such unmapped LUNs andreclaim the disk space uselessly consumed by these LUNs will help administrators avoid unnecessaryupgrades and extensions of their disk arrays

56Reporting a Disk Space Consumption

BMC Performance Manager Express for EMC Disk Arrays

Version 2001

Reporting a Disk SpaceConsumptionMaking sure that a disk array has enough remaining disk space available is critical for severalreasons

middot SAN administrators want to make sure to be able to provision disk space for new servers whenrequested as quickly as possible

middot The disk array itself may need additional disk space for specific features to work properly likeautomatic snapshots mirroring etc

middot If thin provisioning is used the remaining disk space becomes dramatically critical since theinability to allocate additional space to a LUN when requested by the subscriber host will lead tocatastrophic data loss and corruption

The disk space used is permanently monitored for each storage pool The Subscribed Capacityparameter of the Pool class represents the amount of disk space that has been made available tothe subscriber hosts or in other words the amount of disk space that is seen by the serversconnected to disk array

The Consumed Capacity parameter of the SEN_EMC_STORAGEPOOLS class represents the actualspace usage in the storage pool For thin pools (when thin provisioning is enabled on the disk array)this value is normally lower than the Subscribed Capacity as it is the main purpose of thinprovisioning For traditional pools the Consumed Capacity parameters has the same value as theSubscribed Capacity parameter as the entirety of the subscribed disk space is fully allocated inthe storage pool

The Consumed Capacity Percentage parameter is the most critical one as a storage pool usagenearing 100 means that SAN administrators will not be able to create new LUNs in the storagepool By default no alarm or warning threshold is set on this parameter as the fullness of a storagepool may be a normal situation However you can set alert thresholds on this parameter as it fitsyour needs

Managing Baselines and KeyPerformance IndicatorsIn order to facilitate the detection of abnormalities on your monitored environment BMCProactiveNet calculates baselines per parameter (metrics or attributes) based on values collectedover a specified period of time to determine a normal operating range When the collected values forthese parameters are out of range an alert is triggered

Some parameters are identified by default as Key Performance Indicators and therefore automaticallyincluded in the base lining calculation

42Managing Baselines and Key PerformanceIndicators

BMC Performance Manager Express for EMC Disk Arrays

Version 2001

Managing baselines

The baseline is the expected normal operating range for a metric or attribute of a monitor

The baseline is calculated by collecting the values for a monitorrsquos attributes and metrics over aspecified time period and establishing a low baseline value (consisting of the 10th percentile of all thevalues for a given time period) and a high baseline value (consisting of the 90th percentile of all thevalues for a given time period) taking a weighted average of these values over time A higher weightis given to the latest data being factored into the baseline average The accuracy of the baselineimproves over time

Requirements for baseline generation

For baselines to be generated for an attribute that abnormality threshold means that the thresholdexists and is not suppressed Additionally if the Key Performance Indicator (KPI) mode is active only those attributes that have anactive abnormality threshold and are also KPI attributes will have baselines generated for them

Absolute thresholds (with outside baseline) or signature thresholds do not satisfy these requirements

Managing Key Performance Indicators

The KPI attribute of a parameter can be activated or deactivated manually through the BMCProactiveNet Administration Console In this PM some parameters or attributes have beendesignated as important indicators of performance (KPIs) We do not recommend that these defaultsettings are modified

However advanced users may activate or deactivate KPIs from the BMC ProactiveNet AdministrationConsole

To add or remove Key Performance Indicator (KPI) attributes for amonitor type

1 In the Administration Console from the menu bar choose Tools gt KPI AdministrationThe KPI Administration dialog box is displayed

2 From the Monitor Type list choose the monitor type for which you want to add or remove KPIattributes A list of attributes for the selected monitor type is displayed

3 In the KPI column for the attributes that you want to add or remove as Key PerformanceIndicators

middot select the KPI check box to add the corresponding attribute as a KPI

middot deselect the KPI check box to remove the corresponding attribute from the KPIs for thatmonitor type

For complete and detailed information on this procedure please refer to the BMC ProactiveNet documentation availablefrom BMC Web site

BMC Performance Manager Express for EMC Disk Arrays

Version 2001

BMC Performance Manager Express for EMC Disk Arrays monitors all of the performance metrics andusage statistics of your EMC disk arrays such as file disk space usage storage controller utilizationIOs on the diskscontrollersvolumes etc It continuously monitors the activity of each array and isalso able to build reports on past utilization statistics

To setup a complete monitoring of the array we strongly recommend you to also use BMCPerformance Manager Express for Hardware that covers all the physical aspect of the EMC diskarrays (status of the disks ports temperature power supplies power consumption etc)

This chapter explains how to use each monitoring tool ie a separate application class within theBMC Performance Manager Express for EMC Disk Arrays by Sentry Software solution

BMC Performance Manager Express for EMC Disk Arrays is a Performance Manager specifically designedfor BMC Portal consequently it uses the same common features and procedures of BMCreg Portal Thisdocument assumes that the user knows how to use the Portal and therefore explains procedures onlyrelated to BMC Performance Manager Express for EMC Disk Arrays and not on how to add ElementsElement Profiles etc Please refer to the BMC Portal documentation for details on how to use the Portal

Checking Available Spare Disks

To avoid any loss of critical data it is essential for a disk array to always maintain a pool of sparedisks that can replace the faulty disk when a disk failure occurs A disk array without any left sparedisk will not be able to keep the level of data safety and performance in case of a disk failure

The Spare Disk Count parameter of the SEN_EMC_ARRAY class reports the number of spare disksavailable for each disk array monitored with the solution By default a warning is triggered when nospare disk is available (Spare Disk Count is set to zero)

Verifying the Number of Available Spare Disks in Your EMC Disk Arrays

49Checking Available Spare Disks

BMC Performance Manager Express for EMC Disk Arrays

Version 2001

1 Select an element group in the tree view (the main Infrastructure group for example)

2 Click the Reports tab Create a report for the last 24 hours bottom 50 values of the Array|Spare Disk Count parameter of the EMC Disk Arrays application class for the BMC PerformanceManager Express for EMC Disk Arrays by Sentry Software solution

Report ndash Available Spare Disks

Detecting OversubscriptionSituations (Thin Provisioning)We call an oversubscription situation when

1 The storage pool is configured for thin provisioning (ldquothin storage poolrdquo)

2 The storage pool is oversubscribed ie the total disk space visible to the hosts (subscribers) isgreater than its actual capacity (this situation is normal for a thin pool since it is its very purpose)

3 The storage pool actual consumed capacity is nearing 100

Such situation is highly critical because the inability to allocate additional space to a LUN whenrequested by the subscriber host will lead to catastrophic data loss and corruption

When the conditions described above are met the solution sets the Oversubscription Situationparameter to 1 automatically raising a warning By default the warning for OversubscriptionSituation is issued when the Consumed Capacity Percentage parameter goes above 100 Thisthreshold can be configured in the input properties of the solution

50Detecting Oversubscription Situations (ThinProvisioning)

BMC Performance Manager Express for EMC Disk Arrays

Version 2001

Configuring Oversubscription Threshold

1 Click the EMC Disk Arrays icon and then the Configure tab

2 Edit the Oversubscription Situation Threshold () property to the appropriate value Whenthe Oversubscription Situation parameter triggers a warning it is highly recommended thatthe SAN administrators add capacity to the storage pool as soon as possible

Diagnosing Slow LUNs

If a system administrator complains that his servers are experiencing slow IOs performance and thatit is caused by the SAN you may want to verify the actual response time of the LUNs the server isrelying on

The Response Time parameter of the SEN_EMC_VOLUME class represents the average time it tookto complete the read and write operations on the LUN during the collection interval Typically theaverage response time is below 10 milliseconds You may also want to compare this value to theresponse time of the other LUNs to see whether one server is really getting worse IO performancethan another

Volume - Response Time Parameter

If the response time is low you will need to check the amount of data that is written and read onthis LUN The bad performance may simply be due to an abnormally large amount of data to processOtherwise the problem is maybe between the disk array and the server in the fiber links

Pay attention to the file size -the debug output of BMC Performance Manager Express for EMC Disk Arrays could bevery large if enabled for several days

Identifying the Hosts that canAccess a LUNIn most SAN configurations each LUN belongs to a storage group whose host members are the onlyones authorized to access the LUN This is called LUN masking For each LUN the solution displaysits WWN the storage group to which it belongs to as well as the hosts member of this group Inmost cases identifying the storage group of a LUN is sufficient to recognize the server that is usingit

52Identifying LUNs not Owned by their Normal(Default) Storage Processor

BMC Performance Manager Express for EMC Disk Arrays

Version 2001

Identifying LUNs not Owned bytheir Normal (Default) StorageProcessorThe Owning Storage Processor parameter reports the name of the controller that handles IOsfor each LUN If a LUN is not currently handled by its normal (default) storage processors the nameof the default controller will be indicated as SP_B (default SP_A)rdquo

To identify LUNs that are not owned by their normal storage processor you simply need to list the Volume objects where the Owning Storage Processor parameter contains the string Default

Identifying Most Busy LUNs

To identify the LUNs that generate the most traffic on the disk array use the Read Byte Rate andWrite Byte Rate parameters of the LUN class that expose the data throughput for each LUN Usethese parameters to report on the total data traffic (per hour or per day) on each LUN in GB

To make sure that traffic is displayed cumulatively per hour select a time window of at least 12 hours in the graphwindow select at least 7 days to visualize per day cumulative data

1 In the Status tab click the Volume for which you need to check the LUNs activity then expandthe LUNs object to display the ReadWrite Byte Rate parameters

53Identifying Most Busy LUNs

Identifying a Storage Processor(Controllers) OverloadTo visualize the activity of a controller in an EMC disk array use the Processor Utilizationparameter of the SEN_EMC_CONTROLLER class A warning is issued when the processor utilizationgoes too high which means that the controllers cannot keep up with the load on the disk array It isthen important to identify what is overloading the controllers

The Response Time parameter of the SEN_EMC_CONTROLLER class represents the average time ittook the controller to process the read and write requests of the hosts The higher the ResponseTime goes the slower IOs the servers will get By default the solution triggers a warning when thecontroller takes more than 10 milliseconds on average to complete the IO requests and an alarmwhen the response time reaches 100 milliseconds

Monitoring the Efficiency of theCaching MechanismEach controller in an EMC disk array can be configured to use a specified amount of memory tocache the read andor write operations The solution reports the amount of memory configured byeach controller for the read and write operations

The Write Flush Byte Rate represents the rate in MBsec at which data is committed to the disk(ie physically written) This value is to be compared with the Write Byte Rate of the disk array

55Monitoring the Efficiency of the CachingMechanism

BMC Performance Manager Express for EMC Disk Arrays

Version 2001

Comparing W rite Flush Byte Rate w ith W rite Byte Rate

The Cache Dirty Pages Percentage parameter represents the amount in percentage of the writecache that has been modified by host write operations and not yet flushed to the disks Reaching100 means that write case is too small and cannot handle the flow of write operations

Checking the Cache Dirty Pages Percentage

Reclaiming Space of Unmapped(Unused) LUNsOver time as servers connected to a SAN get decommissioned administrators find an increasingnumber of unmapped LUNs or volumes that are no longer used by any server These LUNs whileunused still occupy disk space in the disk array Being able to identify such unmapped LUNs andreclaim the disk space uselessly consumed by these LUNs will help administrators avoid unnecessaryupgrades and extensions of their disk arrays

56Reporting a Disk Space Consumption

BMC Performance Manager Express for EMC Disk Arrays

Version 2001

Reporting a Disk SpaceConsumptionMaking sure that a disk array has enough remaining disk space available is critical for severalreasons

middot SAN administrators want to make sure to be able to provision disk space for new servers whenrequested as quickly as possible

middot The disk array itself may need additional disk space for specific features to work properly likeautomatic snapshots mirroring etc

middot If thin provisioning is used the remaining disk space becomes dramatically critical since theinability to allocate additional space to a LUN when requested by the subscriber host will lead tocatastrophic data loss and corruption

The disk space used is permanently monitored for each storage pool The Subscribed Capacityparameter of the Pool class represents the amount of disk space that has been made available tothe subscriber hosts or in other words the amount of disk space that is seen by the serversconnected to disk array

The Consumed Capacity parameter of the SEN_EMC_STORAGEPOOLS class represents the actualspace usage in the storage pool For thin pools (when thin provisioning is enabled on the disk array)this value is normally lower than the Subscribed Capacity as it is the main purpose of thinprovisioning For traditional pools the Consumed Capacity parameters has the same value as theSubscribed Capacity parameter as the entirety of the subscribed disk space is fully allocated inthe storage pool

The Consumed Capacity Percentage parameter is the most critical one as a storage pool usagenearing 100 means that SAN administrators will not be able to create new LUNs in the storagepool By default no alarm or warning threshold is set on this parameter as the fullness of a storagepool may be a normal situation However you can set alert thresholds on this parameter as it fitsyour needs

57Reporting a Disk Space Consumption

BMC Performance Manager Express for EMC Disk Arrays

Version 2001

Verifying the Available Disk Space in the Storage Pool of your EMC DiskArrays

1 In the Configure tab select an element group in the tree view (the main ldquoInfrastructurerdquogroup for example)

2 Click on the Reports tab

3 Create a report for the last 24 hours top 50 values of the Array|Storage Pools|Disk Group|Storage Pool|Consumed Capacity Percentage parameter of the EMC Disk Arraysapplication class for the BMC Performance Manager Express for EMC Disk Arrays by SentrySoftware solution

Report ndash Disk Space Consumption

Reporting the Total Traffic on anHourly or Daily BasisBMC Performance Manager Express for EMC Disk Arrays not only monitors the traffic and activity ofthe disk array controllers LUNs and physical disks in MBsec but also in GB per hour or per day Theexact amount of data that was read or written to the disk array LUN or physical disk is calculated foreach hour of the day and each day of the week

Each data rate parameter in MBsec is accompanied by a non-rate one in GB These parameters areldquocumulativerdquo their instantaneous value has no meaning and they need to be visualized in a longperiod of time (instead of Read Byte Rate or Write Byte Rate)

58Reporting the Total Traffic on an Hourly orDaily Basis

Managing Baselines and KeyPerformance IndicatorsIn order to facilitate the detection of abnormalities on your monitored environment BMCProactiveNet calculates baselines per parameter (metrics or attributes) based on values collectedover a specified period of time to determine a normal operating range When the collected values forthese parameters are out of range an alert is triggered

Some parameters are identified by default as Key Performance Indicators and therefore automaticallyincluded in the base lining calculation

42Managing Baselines and Key PerformanceIndicators

BMC Performance Manager Express for EMC Disk Arrays

Version 2001

Managing baselines

The baseline is the expected normal operating range for a metric or attribute of a monitor

The baseline is calculated by collecting the values for a monitorrsquos attributes and metrics over aspecified time period and establishing a low baseline value (consisting of the 10th percentile of all thevalues for a given time period) and a high baseline value (consisting of the 90th percentile of all thevalues for a given time period) taking a weighted average of these values over time A higher weightis given to the latest data being factored into the baseline average The accuracy of the baselineimproves over time

Requirements for baseline generation

For baselines to be generated for an attribute that abnormality threshold means that the thresholdexists and is not suppressed Additionally if the Key Performance Indicator (KPI) mode is active only those attributes that have anactive abnormality threshold and are also KPI attributes will have baselines generated for them

Absolute thresholds (with outside baseline) or signature thresholds do not satisfy these requirements

Managing Key Performance Indicators

The KPI attribute of a parameter can be activated or deactivated manually through the BMCProactiveNet Administration Console In this PM some parameters or attributes have beendesignated as important indicators of performance (KPIs) We do not recommend that these defaultsettings are modified

However advanced users may activate or deactivate KPIs from the BMC ProactiveNet AdministrationConsole

To add or remove Key Performance Indicator (KPI) attributes for amonitor type

1 In the Administration Console from the menu bar choose Tools gt KPI AdministrationThe KPI Administration dialog box is displayed

2 From the Monitor Type list choose the monitor type for which you want to add or remove KPIattributes A list of attributes for the selected monitor type is displayed

3 In the KPI column for the attributes that you want to add or remove as Key PerformanceIndicators

middot select the KPI check box to add the corresponding attribute as a KPI

middot deselect the KPI check box to remove the corresponding attribute from the KPIs for thatmonitor type

For complete and detailed information on this procedure please refer to the BMC ProactiveNet documentation availablefrom BMC Web site

Checking Available Spare Disks

To avoid any loss of critical data it is essential for a disk array to always maintain a pool of sparedisks that can replace the faulty disk when a disk failure occurs A disk array without any left sparedisk will not be able to keep the level of data safety and performance in case of a disk failure

The Spare Disk Count parameter of the SEN_EMC_ARRAY class reports the number of spare disksavailable for each disk array monitored with the solution By default a warning is triggered when nospare disk is available (Spare Disk Count is set to zero)

Verifying the Number of Available Spare Disks in Your EMC Disk Arrays

49Checking Available Spare Disks

BMC Performance Manager Express for EMC Disk Arrays

Version 2001

1 Select an element group in the tree view (the main Infrastructure group for example)

2 Click the Reports tab Create a report for the last 24 hours bottom 50 values of the Array|Spare Disk Count parameter of the EMC Disk Arrays application class for the BMC PerformanceManager Express for EMC Disk Arrays by Sentry Software solution

Detecting OversubscriptionSituations (Thin Provisioning)We call an oversubscription situation when

1 The storage pool is configured for thin provisioning (ldquothin storage poolrdquo)

2 The storage pool is oversubscribed ie the total disk space visible to the hosts (subscribers) isgreater than its actual capacity (this situation is normal for a thin pool since it is its very purpose)

3 The storage pool actual consumed capacity is nearing 100

Such situation is highly critical because the inability to allocate additional space to a LUN whenrequested by the subscriber host will lead to catastrophic data loss and corruption

When the conditions described above are met the solution sets the Oversubscription Situationparameter to 1 automatically raising a warning By default the warning for OversubscriptionSituation is issued when the Consumed Capacity Percentage parameter goes above 100 Thisthreshold can be configured in the input properties of the solution

50Detecting Oversubscription Situations (ThinProvisioning)

BMC Performance Manager Express for EMC Disk Arrays

Version 2001

Configuring Oversubscription Threshold

1 Click the EMC Disk Arrays icon and then the Configure tab

2 Edit the Oversubscription Situation Threshold () property to the appropriate value Whenthe Oversubscription Situation parameter triggers a warning it is highly recommended thatthe SAN administrators add capacity to the storage pool as soon as possible

Diagnosing Slow LUNs

If a system administrator complains that his servers are experiencing slow IOs performance and thatit is caused by the SAN you may want to verify the actual response time of the LUNs the server isrelying on

The Response Time parameter of the SEN_EMC_VOLUME class represents the average time it tookto complete the read and write operations on the LUN during the collection interval Typically theaverage response time is below 10 milliseconds You may also want to compare this value to theresponse time of the other LUNs to see whether one server is really getting worse IO performancethan another

Volume - Response Time Parameter

If the response time is low you will need to check the amount of data that is written and read onthis LUN The bad performance may simply be due to an abnormally large amount of data to processOtherwise the problem is maybe between the disk array and the server in the fiber links

51Enabling the Debug Mode

BMC Performance Manager Express for EMC Disk Arrays

Version 2001

Enabling the Debug Mode

By default BMC Performance Manager Express for EMC Disk Arrays sends only the most criticalinformation warning and error messages to the Application Collection Status parameter Mostoften this information is accurate enough to ensure that BMC Performance Manager Express for EMCDisk Arrays is functioning properly If you encounter an issue and wish to report it to customersupport you will be asked to enable the Debug Mode and provide the debug output to the supportteam

1 In the Configure tab gt under Tasks click Elements

2 Select the Element whose debug output you require and click Edit

3 Scroll down to Application Classes gt click the Application class for which you want toenable the debug mode gt click Edit

4 Select Yes from the drop-down Debug Mode list gt SaveBy default BMC Performance Manager Express for EMC Disk Arrays sends its debug output to RSM_HOMERSM(xx)serverrsmlogsen_debuglog

5 Wait for 15 minutes and then disable the debug mode by selecting No

6 Send the debug file to the support team

Pay attention to the file size -the debug output of BMC Performance Manager Express for EMC Disk Arrays could bevery large if enabled for several days

Identifying the Hosts that canAccess a LUNIn most SAN configurations each LUN belongs to a storage group whose host members are the onlyones authorized to access the LUN This is called LUN masking For each LUN the solution displaysits WWN the storage group to which it belongs to as well as the hosts member of this group Inmost cases identifying the storage group of a LUN is sufficient to recognize the server that is usingit

52Identifying LUNs not Owned by their Normal(Default) Storage Processor

BMC Performance Manager Express for EMC Disk Arrays

Version 2001

Identifying LUNs not Owned bytheir Normal (Default) StorageProcessorThe Owning Storage Processor parameter reports the name of the controller that handles IOsfor each LUN If a LUN is not currently handled by its normal (default) storage processors the nameof the default controller will be indicated as SP_B (default SP_A)rdquo

To identify LUNs that are not owned by their normal storage processor you simply need to list the Volume objects where the Owning Storage Processor parameter contains the string Default

Identifying Most Busy LUNs

To identify the LUNs that generate the most traffic on the disk array use the Read Byte Rate andWrite Byte Rate parameters of the LUN class that expose the data throughput for each LUN Usethese parameters to report on the total data traffic (per hour or per day) on each LUN in GB

To make sure that traffic is displayed cumulatively per hour select a time window of at least 12 hours in the graphwindow select at least 7 days to visualize per day cumulative data

1 In the Status tab click the Volume for which you need to check the LUNs activity then expandthe LUNs object to display the ReadWrite Byte Rate parameters

54Identifying Most Busy LUNs

BMC Performance Manager Express for EMC Disk Arrays

Version 2001

View ing a LUNs ReadW rite Byte Rate as a graph

Identifying a Storage Processor(Controllers) OverloadTo visualize the activity of a controller in an EMC disk array use the Processor Utilizationparameter of the SEN_EMC_CONTROLLER class A warning is issued when the processor utilizationgoes too high which means that the controllers cannot keep up with the load on the disk array It isthen important to identify what is overloading the controllers

The Response Time parameter of the SEN_EMC_CONTROLLER class represents the average time ittook the controller to process the read and write requests of the hosts The higher the ResponseTime goes the slower IOs the servers will get By default the solution triggers a warning when thecontroller takes more than 10 milliseconds on average to complete the IO requests and an alarmwhen the response time reaches 100 milliseconds

Monitoring the Efficiency of theCaching MechanismEach controller in an EMC disk array can be configured to use a specified amount of memory tocache the read andor write operations The solution reports the amount of memory configured byeach controller for the read and write operations

The Write Flush Byte Rate represents the rate in MBsec at which data is committed to the disk(ie physically written) This value is to be compared with the Write Byte Rate of the disk array

55Monitoring the Efficiency of the CachingMechanism

BMC Performance Manager Express for EMC Disk Arrays

Version 2001

Comparing W rite Flush Byte Rate w ith W rite Byte Rate

The Cache Dirty Pages Percentage parameter represents the amount in percentage of the writecache that has been modified by host write operations and not yet flushed to the disks Reaching100 means that write case is too small and cannot handle the flow of write operations

Checking the Cache Dirty Pages Percentage

Reclaiming Space of Unmapped(Unused) LUNsOver time as servers connected to a SAN get decommissioned administrators find an increasingnumber of unmapped LUNs or volumes that are no longer used by any server These LUNs whileunused still occupy disk space in the disk array Being able to identify such unmapped LUNs andreclaim the disk space uselessly consumed by these LUNs will help administrators avoid unnecessaryupgrades and extensions of their disk arrays

56Reporting a Disk Space Consumption

BMC Performance Manager Express for EMC Disk Arrays

Version 2001

Reporting a Disk SpaceConsumptionMaking sure that a disk array has enough remaining disk space available is critical for severalreasons

middot SAN administrators want to make sure to be able to provision disk space for new servers whenrequested as quickly as possible

middot The disk array itself may need additional disk space for specific features to work properly likeautomatic snapshots mirroring etc

middot If thin provisioning is used the remaining disk space becomes dramatically critical since theinability to allocate additional space to a LUN when requested by the subscriber host will lead tocatastrophic data loss and corruption

The disk space used is permanently monitored for each storage pool The Subscribed Capacityparameter of the Pool class represents the amount of disk space that has been made available tothe subscriber hosts or in other words the amount of disk space that is seen by the serversconnected to disk array

The Consumed Capacity parameter of the SEN_EMC_STORAGEPOOLS class represents the actualspace usage in the storage pool For thin pools (when thin provisioning is enabled on the disk array)this value is normally lower than the Subscribed Capacity as it is the main purpose of thinprovisioning For traditional pools the Consumed Capacity parameters has the same value as theSubscribed Capacity parameter as the entirety of the subscribed disk space is fully allocated inthe storage pool

The Consumed Capacity Percentage parameter is the most critical one as a storage pool usagenearing 100 means that SAN administrators will not be able to create new LUNs in the storagepool By default no alarm or warning threshold is set on this parameter as the fullness of a storagepool may be a normal situation However you can set alert thresholds on this parameter as it fitsyour needs

Setting thresholds

Whenever relevant BMC Performance Manager Express for EMC Disk Arrays automatically setsthresholds for parameters If you prefer a more fault-tolerant monitoring you can modify thethresholds of each parameter through the Configure tab gt Edit Thresholds

It is strongly recommended to wait for all the storage objects to be discovered before setting threshold values to avoidhaving to enter thresholds for each occurrence of the application class

To modify the parameter thresholds of several storage objects of an element

60Setting thresholds

BMC Performance Manager Express for EMC Disk Arrays

Version 2001

1 In the Configure tab click on the Storage (ltplatformgt) or the instance icon gt Edit

Thresholds Properties and Credentials

Any modification to the thresholds or any other properties of elements created using the Element

Profile mode is to be done using the Element Profile route or by clicking Override Profile

2 Uncheck the Warning and Alarm boxes for all the parameters for which you want to disablethe alert conditions

Managing Baselines and KeyPerformance IndicatorsIn order to facilitate the detection of abnormalities on your monitored environment BMCProactiveNet calculates baselines per parameter (metrics or attributes) based on values collectedover a specified period of time to determine a normal operating range When the collected values forthese parameters are out of range an alert is triggered

Some parameters are identified by default as Key Performance Indicators and therefore automaticallyincluded in the base lining calculation

42Managing Baselines and Key PerformanceIndicators

BMC Performance Manager Express for EMC Disk Arrays

Version 2001

Managing baselines

The baseline is the expected normal operating range for a metric or attribute of a monitor

The baseline is calculated by collecting the values for a monitorrsquos attributes and metrics over aspecified time period and establishing a low baseline value (consisting of the 10th percentile of all thevalues for a given time period) and a high baseline value (consisting of the 90th percentile of all thevalues for a given time period) taking a weighted average of these values over time A higher weightis given to the latest data being factored into the baseline average The accuracy of the baselineimproves over time

Requirements for baseline generation

For baselines to be generated for an attribute that abnormality threshold means that the thresholdexists and is not suppressed Additionally if the Key Performance Indicator (KPI) mode is active only those attributes that have anactive abnormality threshold and are also KPI attributes will have baselines generated for them

Absolute thresholds (with outside baseline) or signature thresholds do not satisfy these requirements

Managing Key Performance Indicators

The KPI attribute of a parameter can be activated or deactivated manually through the BMCProactiveNet Administration Console In this PM some parameters or attributes have beendesignated as important indicators of performance (KPIs) We do not recommend that these defaultsettings are modified

However advanced users may activate or deactivate KPIs from the BMC ProactiveNet AdministrationConsole

To add or remove Key Performance Indicator (KPI) attributes for amonitor type

1 In the Administration Console from the menu bar choose Tools gt KPI AdministrationThe KPI Administration dialog box is displayed

2 From the Monitor Type list choose the monitor type for which you want to add or remove KPIattributes A list of attributes for the selected monitor type is displayed

3 In the KPI column for the attributes that you want to add or remove as Key PerformanceIndicators

middot select the KPI check box to add the corresponding attribute as a KPI

middot deselect the KPI check box to remove the corresponding attribute from the KPIs for thatmonitor type

For complete and detailed information on this procedure please refer to the BMC ProactiveNet documentation availablefrom BMC Web site

To setup a complete monitoring of the array we strongly recommend you to also use BMCPerformance Manager Express for Hardware that covers all the physical aspect of the EMC diskarrays (status of the disks ports temperature power supplies power consumption etc)

This chapter explains how to use each monitoring tool ie a separate application class within theBMC Performance Manager Express for EMC Disk Arrays by Sentry Software solution

BMC Performance Manager Express for EMC Disk Arrays is a Performance Manager specifically designedfor BMC Portal consequently it uses the same common features and procedures of BMCreg Portal Thisdocument assumes that the user knows how to use the Portal and therefore explains procedures onlyrelated to BMC Performance Manager Express for EMC Disk Arrays and not on how to add ElementsElement Profiles etc Please refer to the BMC Portal documentation for details on how to use the Portal

Checking Available Spare Disks

To avoid any loss of critical data it is essential for a disk array to always maintain a pool of sparedisks that can replace the faulty disk when a disk failure occurs A disk array without any left sparedisk will not be able to keep the level of data safety and performance in case of a disk failure

The Spare Disk Count parameter of the SEN_EMC_ARRAY class reports the number of spare disksavailable for each disk array monitored with the solution By default a warning is triggered when nospare disk is available (Spare Disk Count is set to zero)

Verifying the Number of Available Spare Disks in Your EMC Disk Arrays

49Checking Available Spare Disks

BMC Performance Manager Express for EMC Disk Arrays

Version 2001

1 Select an element group in the tree view (the main Infrastructure group for example)

2 Click the Reports tab Create a report for the last 24 hours bottom 50 values of the Array|Spare Disk Count parameter of the EMC Disk Arrays application class for the BMC PerformanceManager Express for EMC Disk Arrays by Sentry Software solution

Detecting OversubscriptionSituations (Thin Provisioning)We call an oversubscription situation when

1 The storage pool is configured for thin provisioning (ldquothin storage poolrdquo)

2 The storage pool is oversubscribed ie the total disk space visible to the hosts (subscribers) isgreater than its actual capacity (this situation is normal for a thin pool since it is its very purpose)

3 The storage pool actual consumed capacity is nearing 100

Such situation is highly critical because the inability to allocate additional space to a LUN whenrequested by the subscriber host will lead to catastrophic data loss and corruption

When the conditions described above are met the solution sets the Oversubscription Situationparameter to 1 automatically raising a warning By default the warning for OversubscriptionSituation is issued when the Consumed Capacity Percentage parameter goes above 100 Thisthreshold can be configured in the input properties of the solution

50Detecting Oversubscription Situations (ThinProvisioning)

BMC Performance Manager Express for EMC Disk Arrays

Version 2001

Configuring Oversubscription Threshold

1 Click the EMC Disk Arrays icon and then the Configure tab

2 Edit the Oversubscription Situation Threshold () property to the appropriate value Whenthe Oversubscription Situation parameter triggers a warning it is highly recommended thatthe SAN administrators add capacity to the storage pool as soon as possible

Diagnosing Slow LUNs

If a system administrator complains that his servers are experiencing slow IOs performance and thatit is caused by the SAN you may want to verify the actual response time of the LUNs the server isrelying on

The Response Time parameter of the SEN_EMC_VOLUME class represents the average time it tookto complete the read and write operations on the LUN during the collection interval Typically theaverage response time is below 10 milliseconds You may also want to compare this value to theresponse time of the other LUNs to see whether one server is really getting worse IO performancethan another

Volume - Response Time Parameter

If the response time is low you will need to check the amount of data that is written and read onthis LUN The bad performance may simply be due to an abnormally large amount of data to processOtherwise the problem is maybe between the disk array and the server in the fiber links

51Enabling the Debug Mode

BMC Performance Manager Express for EMC Disk Arrays

Version 2001

Enabling the Debug Mode

By default BMC Performance Manager Express for EMC Disk Arrays sends only the most criticalinformation warning and error messages to the Application Collection Status parameter Mostoften this information is accurate enough to ensure that BMC Performance Manager Express for EMCDisk Arrays is functioning properly If you encounter an issue and wish to report it to customersupport you will be asked to enable the Debug Mode and provide the debug output to the supportteam

1 In the Configure tab gt under Tasks click Elements

2 Select the Element whose debug output you require and click Edit

3 Scroll down to Application Classes gt click the Application class for which you want toenable the debug mode gt click Edit

4 Select Yes from the drop-down Debug Mode list gt SaveBy default BMC Performance Manager Express for EMC Disk Arrays sends its debug output to RSM_HOMERSM(xx)serverrsmlogsen_debuglog

5 Wait for 15 minutes and then disable the debug mode by selecting No

6 Send the debug file to the support team

Pay attention to the file size -the debug output of BMC Performance Manager Express for EMC Disk Arrays could bevery large if enabled for several days

Identifying the Hosts that canAccess a LUNIn most SAN configurations each LUN belongs to a storage group whose host members are the onlyones authorized to access the LUN This is called LUN masking For each LUN the solution displaysits WWN the storage group to which it belongs to as well as the hosts member of this group Inmost cases identifying the storage group of a LUN is sufficient to recognize the server that is usingit

52Identifying LUNs not Owned by their Normal(Default) Storage Processor

BMC Performance Manager Express for EMC Disk Arrays

Version 2001

Identifying LUNs not Owned bytheir Normal (Default) StorageProcessorThe Owning Storage Processor parameter reports the name of the controller that handles IOsfor each LUN If a LUN is not currently handled by its normal (default) storage processors the nameof the default controller will be indicated as SP_B (default SP_A)rdquo

To identify LUNs that are not owned by their normal storage processor you simply need to list the Volume objects where the Owning Storage Processor parameter contains the string Default

Identifying Most Busy LUNs

To identify the LUNs that generate the most traffic on the disk array use the Read Byte Rate andWrite Byte Rate parameters of the LUN class that expose the data throughput for each LUN Usethese parameters to report on the total data traffic (per hour or per day) on each LUN in GB

To make sure that traffic is displayed cumulatively per hour select a time window of at least 12 hours in the graphwindow select at least 7 days to visualize per day cumulative data

1 In the Status tab click the Volume for which you need to check the LUNs activity then expandthe LUNs object to display the ReadWrite Byte Rate parameters

53Identifying Most Busy LUNs

Version 2001

View ing a LUNs ReadW rite Byte Rate as a graph

Identifying a Storage Processor(Controllers) OverloadTo visualize the activity of a controller in an EMC disk array use the Processor Utilizationparameter of the SEN_EMC_CONTROLLER class A warning is issued when the processor utilizationgoes too high which means that the controllers cannot keep up with the load on the disk array It isthen important to identify what is overloading the controllers

The Response Time parameter of the SEN_EMC_CONTROLLER class represents the average time ittook the controller to process the read and write requests of the hosts The higher the ResponseTime goes the slower IOs the servers will get By default the solution triggers a warning when thecontroller takes more than 10 milliseconds on average to complete the IO requests and an alarmwhen the response time reaches 100 milliseconds

Monitoring the Efficiency of theCaching MechanismEach controller in an EMC disk array can be configured to use a specified amount of memory tocache the read andor write operations The solution reports the amount of memory configured byeach controller for the read and write operations

The Write Flush Byte Rate represents the rate in MBsec at which data is committed to the disk(ie physically written) This value is to be compared with the Write Byte Rate of the disk array

55Monitoring the Efficiency of the CachingMechanism

BMC Performance Manager Express for EMC Disk Arrays

Version 2001

Comparing W rite Flush Byte Rate w ith W rite Byte Rate

The Cache Dirty Pages Percentage parameter represents the amount in percentage of the writecache that has been modified by host write operations and not yet flushed to the disks Reaching100 means that write case is too small and cannot handle the flow of write operations

Checking the Cache Dirty Pages Percentage

Reclaiming Space of Unmapped(Unused) LUNsOver time as servers connected to a SAN get decommissioned administrators find an increasingnumber of unmapped LUNs or volumes that are no longer used by any server These LUNs whileunused still occupy disk space in the disk array Being able to identify such unmapped LUNs andreclaim the disk space uselessly consumed by these LUNs will help administrators avoid unnecessaryupgrades and extensions of their disk arrays

56Reporting a Disk Space Consumption

BMC Performance Manager Express for EMC Disk Arrays

Version 2001

Reporting a Disk SpaceConsumptionMaking sure that a disk array has enough remaining disk space available is critical for severalreasons

middot SAN administrators want to make sure to be able to provision disk space for new servers whenrequested as quickly as possible

middot The disk array itself may need additional disk space for specific features to work properly likeautomatic snapshots mirroring etc

middot If thin provisioning is used the remaining disk space becomes dramatically critical since theinability to allocate additional space to a LUN when requested by the subscriber host will lead tocatastrophic data loss and corruption

The disk space used is permanently monitored for each storage pool The Subscribed Capacityparameter of the Pool class represents the amount of disk space that has been made available tothe subscriber hosts or in other words the amount of disk space that is seen by the serversconnected to disk array

The Consumed Capacity parameter of the SEN_EMC_STORAGEPOOLS class represents the actualspace usage in the storage pool For thin pools (when thin provisioning is enabled on the disk array)this value is normally lower than the Subscribed Capacity as it is the main purpose of thinprovisioning For traditional pools the Consumed Capacity parameters has the same value as theSubscribed Capacity parameter as the entirety of the subscribed disk space is fully allocated inthe storage pool

The Consumed Capacity Percentage parameter is the most critical one as a storage pool usagenearing 100 means that SAN administrators will not be able to create new LUNs in the storagepool By default no alarm or warning threshold is set on this parameter as the fullness of a storagepool may be a normal situation However you can set alert thresholds on this parameter as it fitsyour needs

Managing Baselines and KeyPerformance IndicatorsIn order to facilitate the detection of abnormalities on your monitored environment BMCProactiveNet calculates baselines per parameter (metrics or attributes) based on values collectedover a specified period of time to determine a normal operating range When the collected values forthese parameters are out of range an alert is triggered

Some parameters are identified by default as Key Performance Indicators and therefore automaticallyincluded in the base lining calculation

42Managing Baselines and Key PerformanceIndicators

BMC Performance Manager Express for EMC Disk Arrays

Version 2001

Managing baselines

The baseline is the expected normal operating range for a metric or attribute of a monitor

The baseline is calculated by collecting the values for a monitorrsquos attributes and metrics over aspecified time period and establishing a low baseline value (consisting of the 10th percentile of all thevalues for a given time period) and a high baseline value (consisting of the 90th percentile of all thevalues for a given time period) taking a weighted average of these values over time A higher weightis given to the latest data being factored into the baseline average The accuracy of the baselineimproves over time

Requirements for baseline generation

For baselines to be generated for an attribute that abnormality threshold means that the thresholdexists and is not suppressed Additionally if the Key Performance Indicator (KPI) mode is active only those attributes that have anactive abnormality threshold and are also KPI attributes will have baselines generated for them

Absolute thresholds (with outside baseline) or signature thresholds do not satisfy these requirements

Managing Key Performance Indicators

The KPI attribute of a parameter can be activated or deactivated manually through the BMCProactiveNet Administration Console In this PM some parameters or attributes have beendesignated as important indicators of performance (KPIs) We do not recommend that these defaultsettings are modified

However advanced users may activate or deactivate KPIs from the BMC ProactiveNet AdministrationConsole

To add or remove Key Performance Indicator (KPI) attributes for amonitor type

1 In the Administration Console from the menu bar choose Tools gt KPI AdministrationThe KPI Administration dialog box is displayed

2 From the Monitor Type list choose the monitor type for which you want to add or remove KPIattributes A list of attributes for the selected monitor type is displayed

3 In the KPI column for the attributes that you want to add or remove as Key PerformanceIndicators

middot select the KPI check box to add the corresponding attribute as a KPI

middot deselect the KPI check box to remove the corresponding attribute from the KPIs for thatmonitor type

For complete and detailed information on this procedure please refer to the BMC ProactiveNet documentation availablefrom BMC Web site

BMC Performance Manager Express for EMC Disk Arrays monitors all of the performance metrics andusage statistics of your EMC disk arrays such as file disk space usage storage controller utilizationIOs on the diskscontrollersvolumes etc It continuously monitors the activity of each array and isalso able to build reports on past utilization statistics

To setup a complete monitoring of the array we strongly recommend you to also use BMCPerformance Manager Express for Hardware that covers all the physical aspect of the EMC diskarrays (status of the disks ports temperature power supplies power consumption etc)

This chapter explains how to use each monitoring tool ie a separate application class within theBMC Performance Manager Express for EMC Disk Arrays by Sentry Software solution

BMC Performance Manager Express for EMC Disk Arrays is a Performance Manager specifically designedfor BMC Portal consequently it uses the same common features and procedures of BMCreg Portal Thisdocument assumes that the user knows how to use the Portal and therefore explains procedures onlyrelated to BMC Performance Manager Express for EMC Disk Arrays and not on how to add ElementsElement Profiles etc Please refer to the BMC Portal documentation for details on how to use the Portal

Checking Available Spare Disks

To avoid any loss of critical data it is essential for a disk array to always maintain a pool of sparedisks that can replace the faulty disk when a disk failure occurs A disk array without any left sparedisk will not be able to keep the level of data safety and performance in case of a disk failure

The Spare Disk Count parameter of the SEN_EMC_ARRAY class reports the number of spare disksavailable for each disk array monitored with the solution By default a warning is triggered when nospare disk is available (Spare Disk Count is set to zero)

Verifying the Number of Available Spare Disks in Your EMC Disk Arrays

49Checking Available Spare Disks

BMC Performance Manager Express for EMC Disk Arrays

Version 2001

1 Select an element group in the tree view (the main Infrastructure group for example)

2 Click the Reports tab Create a report for the last 24 hours bottom 50 values of the Array|Spare Disk Count parameter of the EMC Disk Arrays application class for the BMC PerformanceManager Express for EMC Disk Arrays by Sentry Software solution

Detecting OversubscriptionSituations (Thin Provisioning)We call an oversubscription situation when

1 The storage pool is configured for thin provisioning (ldquothin storage poolrdquo)

2 The storage pool is oversubscribed ie the total disk space visible to the hosts (subscribers) isgreater than its actual capacity (this situation is normal for a thin pool since it is its very purpose)

3 The storage pool actual consumed capacity is nearing 100

Such situation is highly critical because the inability to allocate additional space to a LUN whenrequested by the subscriber host will lead to catastrophic data loss and corruption

When the conditions described above are met the solution sets the Oversubscription Situationparameter to 1 automatically raising a warning By default the warning for OversubscriptionSituation is issued when the Consumed Capacity Percentage parameter goes above 100 Thisthreshold can be configured in the input properties of the solution

50Detecting Oversubscription Situations (ThinProvisioning)

BMC Performance Manager Express for EMC Disk Arrays

Version 2001

Configuring Oversubscription Threshold

1 Click the EMC Disk Arrays icon and then the Configure tab

2 Edit the Oversubscription Situation Threshold () property to the appropriate value Whenthe Oversubscription Situation parameter triggers a warning it is highly recommended thatthe SAN administrators add capacity to the storage pool as soon as possible

Diagnosing Slow LUNs

If a system administrator complains that his servers are experiencing slow IOs performance and thatit is caused by the SAN you may want to verify the actual response time of the LUNs the server isrelying on

The Response Time parameter of the SEN_EMC_VOLUME class represents the average time it tookto complete the read and write operations on the LUN during the collection interval Typically theaverage response time is below 10 milliseconds You may also want to compare this value to theresponse time of the other LUNs to see whether one server is really getting worse IO performancethan another

Volume - Response Time Parameter

If the response time is low you will need to check the amount of data that is written and read onthis LUN The bad performance may simply be due to an abnormally large amount of data to processOtherwise the problem is maybe between the disk array and the server in the fiber links

51Enabling the Debug Mode

BMC Performance Manager Express for EMC Disk Arrays

Version 2001

Enabling the Debug Mode

By default BMC Performance Manager Express for EMC Disk Arrays sends only the most criticalinformation warning and error messages to the Application Collection Status parameter Mostoften this information is accurate enough to ensure that BMC Performance Manager Express for EMCDisk Arrays is functioning properly If you encounter an issue and wish to report it to customersupport you will be asked to enable the Debug Mode and provide the debug output to the supportteam

1 In the Configure tab gt under Tasks click Elements

2 Select the Element whose debug output you require and click Edit

3 Scroll down to Application Classes gt click the Application class for which you want toenable the debug mode gt click Edit

4 Select Yes from the drop-down Debug Mode list gt SaveBy default BMC Performance Manager Express for EMC Disk Arrays sends its debug output to RSM_HOMERSM(xx)serverrsmlogsen_debuglog

5 Wait for 15 minutes and then disable the debug mode by selecting No

6 Send the debug file to the support team

Pay attention to the file size -the debug output of BMC Performance Manager Express for EMC Disk Arrays could bevery large if enabled for several days

Identifying the Hosts that canAccess a LUNIn most SAN configurations each LUN belongs to a storage group whose host members are the onlyones authorized to access the LUN This is called LUN masking For each LUN the solution displaysits WWN the storage group to which it belongs to as well as the hosts member of this group Inmost cases identifying the storage group of a LUN is sufficient to recognize the server that is usingit

52Identifying LUNs not Owned by their Normal(Default) Storage Processor

BMC Performance Manager Express for EMC Disk Arrays

Version 2001

Identifying LUNs not Owned bytheir Normal (Default) StorageProcessorThe Owning Storage Processor parameter reports the name of the controller that handles IOsfor each LUN If a LUN is not currently handled by its normal (default) storage processors the nameof the default controller will be indicated as SP_B (default SP_A)rdquo

To identify LUNs that are not owned by their normal storage processor you simply need to list the Volume objects where the Owning Storage Processor parameter contains the string Default

Identifying Most Busy LUNs

To identify the LUNs that generate the most traffic on the disk array use the Read Byte Rate andWrite Byte Rate parameters of the LUN class that expose the data throughput for each LUN Usethese parameters to report on the total data traffic (per hour or per day) on each LUN in GB

To make sure that traffic is displayed cumulatively per hour select a time window of at least 12 hours in the graphwindow select at least 7 days to visualize per day cumulative data

1 In the Status tab click the Volume for which you need to check the LUNs activity then expandthe LUNs object to display the ReadWrite Byte Rate parameters

53Identifying Most Busy LUNs

Version 2001

View ing a LUNs ReadW rite Byte Rate as a graph

Identifying a Storage Processor(Controllers) OverloadTo visualize the activity of a controller in an EMC disk array use the Processor Utilizationparameter of the SEN_EMC_CONTROLLER class A warning is issued when the processor utilizationgoes too high which means that the controllers cannot keep up with the load on the disk array It isthen important to identify what is overloading the controllers

The Response Time parameter of the SEN_EMC_CONTROLLER class represents the average time ittook the controller to process the read and write requests of the hosts The higher the ResponseTime goes the slower IOs the servers will get By default the solution triggers a warning when thecontroller takes more than 10 milliseconds on average to complete the IO requests and an alarmwhen the response time reaches 100 milliseconds

Monitoring the Efficiency of theCaching MechanismEach controller in an EMC disk array can be configured to use a specified amount of memory tocache the read andor write operations The solution reports the amount of memory configured byeach controller for the read and write operations

The Write Flush Byte Rate represents the rate in MBsec at which data is committed to the disk(ie physically written) This value is to be compared with the Write Byte Rate of the disk array

55Monitoring the Efficiency of the CachingMechanism

BMC Performance Manager Express for EMC Disk Arrays

Version 2001

Comparing W rite Flush Byte Rate w ith W rite Byte Rate

The Cache Dirty Pages Percentage parameter represents the amount in percentage of the writecache that has been modified by host write operations and not yet flushed to the disks Reaching100 means that write case is too small and cannot handle the flow of write operations

Checking the Cache Dirty Pages Percentage

Reclaiming Space of Unmapped(Unused) LUNsOver time as servers connected to a SAN get decommissioned administrators find an increasingnumber of unmapped LUNs or volumes that are no longer used by any server These LUNs whileunused still occupy disk space in the disk array Being able to identify such unmapped LUNs andreclaim the disk space uselessly consumed by these LUNs will help administrators avoid unnecessaryupgrades and extensions of their disk arrays

56Reporting a Disk Space Consumption

BMC Performance Manager Express for EMC Disk Arrays

Version 2001

Reporting a Disk SpaceConsumptionMaking sure that a disk array has enough remaining disk space available is critical for severalreasons

middot SAN administrators want to make sure to be able to provision disk space for new servers whenrequested as quickly as possible

middot The disk array itself may need additional disk space for specific features to work properly likeautomatic snapshots mirroring etc

middot If thin provisioning is used the remaining disk space becomes dramatically critical since theinability to allocate additional space to a LUN when requested by the subscriber host will lead tocatastrophic data loss and corruption

The disk space used is permanently monitored for each storage pool The Subscribed Capacityparameter of the Pool class represents the amount of disk space that has been made available tothe subscriber hosts or in other words the amount of disk space that is seen by the serversconnected to disk array

The Consumed Capacity parameter of the SEN_EMC_STORAGEPOOLS class represents the actualspace usage in the storage pool For thin pools (when thin provisioning is enabled on the disk array)this value is normally lower than the Subscribed Capacity as it is the main purpose of thinprovisioning For traditional pools the Consumed Capacity parameters has the same value as theSubscribed Capacity parameter as the entirety of the subscribed disk space is fully allocated inthe storage pool

The Consumed Capacity Percentage parameter is the most critical one as a storage pool usagenearing 100 means that SAN administrators will not be able to create new LUNs in the storagepool By default no alarm or warning threshold is set on this parameter as the fullness of a storagepool may be a normal situation However you can set alert thresholds on this parameter as it fitsyour needs

We strongly recommend that you create a specific adapter for each PM you need to integrate into BMCProactiveNet to enable the update of a single PM independently

Once created and imported the Adapter will be displayed in the Devices folder of the BMCProactiveNet Operations Console

Managing Baselines and KeyPerformance IndicatorsIn order to facilitate the detection of abnormalities on your monitored environment BMCProactiveNet calculates baselines per parameter (metrics or attributes) based on values collectedover a specified period of time to determine a normal operating range When the collected values forthese parameters are out of range an alert is triggered

Some parameters are identified by default as Key Performance Indicators and therefore automaticallyincluded in the base lining calculation

42Managing Baselines and Key PerformanceIndicators

BMC Performance Manager Express for EMC Disk Arrays

Version 2001

Managing baselines

The baseline is the expected normal operating range for a metric or attribute of a monitor

The baseline is calculated by collecting the values for a monitorrsquos attributes and metrics over aspecified time period and establishing a low baseline value (consisting of the 10th percentile of all thevalues for a given time period) and a high baseline value (consisting of the 90th percentile of all thevalues for a given time period) taking a weighted average of these values over time A higher weightis given to the latest data being factored into the baseline average The accuracy of the baselineimproves over time

Requirements for baseline generation

For baselines to be generated for an attribute that abnormality threshold means that the thresholdexists and is not suppressed Additionally if the Key Performance Indicator (KPI) mode is active only those attributes that have anactive abnormality threshold and are also KPI attributes will have baselines generated for them

Absolute thresholds (with outside baseline) or signature thresholds do not satisfy these requirements

Managing Key Performance Indicators

The KPI attribute of a parameter can be activated or deactivated manually through the BMCProactiveNet Administration Console In this PM some parameters or attributes have beendesignated as important indicators of performance (KPIs) We do not recommend that these defaultsettings are modified

However advanced users may activate or deactivate KPIs from the BMC ProactiveNet AdministrationConsole

To add or remove Key Performance Indicator (KPI) attributes for amonitor type

1 In the Administration Console from the menu bar choose Tools gt KPI AdministrationThe KPI Administration dialog box is displayed

2 From the Monitor Type list choose the monitor type for which you want to add or remove KPIattributes A list of attributes for the selected monitor type is displayed

3 In the KPI column for the attributes that you want to add or remove as Key PerformanceIndicators

middot select the KPI check box to add the corresponding attribute as a KPI

middot deselect the KPI check box to remove the corresponding attribute from the KPIs for thatmonitor type

For complete and detailed information on this procedure please refer to the BMC ProactiveNet documentation availablefrom BMC Web site

BMC Performance Manager Express for EMC Disk Arrays

Version 2001

BMC Performance Manager Express for EMC Disk Arrays monitors all of the performance metrics andusage statistics of your EMC disk arrays such as file disk space usage storage controller utilizationIOs on the diskscontrollersvolumes etc It continuously monitors the activity of each array and isalso able to build reports on past utilization statistics

To setup a complete monitoring of the array we strongly recommend you to also use BMCPerformance Manager Express for Hardware that covers all the physical aspect of the EMC diskarrays (status of the disks ports temperature power supplies power consumption etc)

This chapter explains how to use each monitoring tool ie a separate application class within theBMC Performance Manager Express for EMC Disk Arrays by Sentry Software solution

BMC Performance Manager Express for EMC Disk Arrays is a Performance Manager specifically designedfor BMC Portal consequently it uses the same common features and procedures of BMCreg Portal Thisdocument assumes that the user knows how to use the Portal and therefore explains procedures onlyrelated to BMC Performance Manager Express for EMC Disk Arrays and not on how to add ElementsElement Profiles etc Please refer to the BMC Portal documentation for details on how to use the Portal

Checking Available Spare Disks

To avoid any loss of critical data it is essential for a disk array to always maintain a pool of sparedisks that can replace the faulty disk when a disk failure occurs A disk array without any left sparedisk will not be able to keep the level of data safety and performance in case of a disk failure

The Spare Disk Count parameter of the SEN_EMC_ARRAY class reports the number of spare disksavailable for each disk array monitored with the solution By default a warning is triggered when nospare disk is available (Spare Disk Count is set to zero)

Verifying the Number of Available Spare Disks in Your EMC Disk Arrays

Detecting OversubscriptionSituations (Thin Provisioning)We call an oversubscription situation when

1 The storage pool is configured for thin provisioning (ldquothin storage poolrdquo)

2 The storage pool is oversubscribed ie the total disk space visible to the hosts (subscribers) isgreater than its actual capacity (this situation is normal for a thin pool since it is its very purpose)

3 The storage pool actual consumed capacity is nearing 100

Such situation is highly critical because the inability to allocate additional space to a LUN whenrequested by the subscriber host will lead to catastrophic data loss and corruption

When the conditions described above are met the solution sets the Oversubscription Situationparameter to 1 automatically raising a warning By default the warning for OversubscriptionSituation is issued when the Consumed Capacity Percentage parameter goes above 100 Thisthreshold can be configured in the input properties of the solution

50Detecting Oversubscription Situations (ThinProvisioning)

BMC Performance Manager Express for EMC Disk Arrays

Version 2001

Configuring Oversubscription Threshold

1 Click the EMC Disk Arrays icon and then the Configure tab

2 Edit the Oversubscription Situation Threshold () property to the appropriate value Whenthe Oversubscription Situation parameter triggers a warning it is highly recommended thatthe SAN administrators add capacity to the storage pool as soon as possible

Diagnosing Slow LUNs

If a system administrator complains that his servers are experiencing slow IOs performance and thatit is caused by the SAN you may want to verify the actual response time of the LUNs the server isrelying on

The Response Time parameter of the SEN_EMC_VOLUME class represents the average time it tookto complete the read and write operations on the LUN during the collection interval Typically theaverage response time is below 10 milliseconds You may also want to compare this value to theresponse time of the other LUNs to see whether one server is really getting worse IO performancethan another

Volume - Response Time Parameter

If the response time is low you will need to check the amount of data that is written and read onthis LUN The bad performance may simply be due to an abnormally large amount of data to processOtherwise the problem is maybe between the disk array and the server in the fiber links

51Enabling the Debug Mode

BMC Performance Manager Express for EMC Disk Arrays

Version 2001

Enabling the Debug Mode

By default BMC Performance Manager Express for EMC Disk Arrays sends only the most criticalinformation warning and error messages to the Application Collection Status parameter Mostoften this information is accurate enough to ensure that BMC Performance Manager Express for EMCDisk Arrays is functioning properly If you encounter an issue and wish to report it to customersupport you will be asked to enable the Debug Mode and provide the debug output to the supportteam

1 In the Configure tab gt under Tasks click Elements

2 Select the Element whose debug output you require and click Edit

3 Scroll down to Application Classes gt click the Application class for which you want toenable the debug mode gt click Edit

4 Select Yes from the drop-down Debug Mode list gt SaveBy default BMC Performance Manager Express for EMC Disk Arrays sends its debug output to RSM_HOMERSM(xx)serverrsmlogsen_debuglog

5 Wait for 15 minutes and then disable the debug mode by selecting No

6 Send the debug file to the support team

Pay attention to the file size -the debug output of BMC Performance Manager Express for EMC Disk Arrays could bevery large if enabled for several days

Identifying the Hosts that canAccess a LUNIn most SAN configurations each LUN belongs to a storage group whose host members are the onlyones authorized to access the LUN This is called LUN masking For each LUN the solution displaysits WWN the storage group to which it belongs to as well as the hosts member of this group Inmost cases identifying the storage group of a LUN is sufficient to recognize the server that is usingit

52Identifying LUNs not Owned by their Normal(Default) Storage Processor

BMC Performance Manager Express for EMC Disk Arrays

Version 2001

Identifying LUNs not Owned bytheir Normal (Default) StorageProcessorThe Owning Storage Processor parameter reports the name of the controller that handles IOsfor each LUN If a LUN is not currently handled by its normal (default) storage processors the nameof the default controller will be indicated as SP_B (default SP_A)rdquo

To identify LUNs that are not owned by their normal storage processor you simply need to list the Volume objects where the Owning Storage Processor parameter contains the string Default

Identifying Most Busy LUNs

To identify the LUNs that generate the most traffic on the disk array use the Read Byte Rate andWrite Byte Rate parameters of the LUN class that expose the data throughput for each LUN Usethese parameters to report on the total data traffic (per hour or per day) on each LUN in GB

To make sure that traffic is displayed cumulatively per hour select a time window of at least 12 hours in the graphwindow select at least 7 days to visualize per day cumulative data

1 In the Status tab click the Volume for which you need to check the LUNs activity then expandthe LUNs object to display the ReadWrite Byte Rate parameters

53Identifying Most Busy LUNs

Version 2001

View ing a LUNs ReadW rite Byte Rate as a graph

Identifying a Storage Processor(Controllers) OverloadTo visualize the activity of a controller in an EMC disk array use the Processor Utilizationparameter of the SEN_EMC_CONTROLLER class A warning is issued when the processor utilizationgoes too high which means that the controllers cannot keep up with the load on the disk array It isthen important to identify what is overloading the controllers

The Response Time parameter of the SEN_EMC_CONTROLLER class represents the average time ittook the controller to process the read and write requests of the hosts The higher the ResponseTime goes the slower IOs the servers will get By default the solution triggers a warning when thecontroller takes more than 10 milliseconds on average to complete the IO requests and an alarmwhen the response time reaches 100 milliseconds

Monitoring the Efficiency of theCaching MechanismEach controller in an EMC disk array can be configured to use a specified amount of memory tocache the read andor write operations The solution reports the amount of memory configured byeach controller for the read and write operations

The Write Flush Byte Rate represents the rate in MBsec at which data is committed to the disk(ie physically written) This value is to be compared with the Write Byte Rate of the disk array

55Monitoring the Efficiency of the CachingMechanism

BMC Performance Manager Express for EMC Disk Arrays

Version 2001

Comparing W rite Flush Byte Rate w ith W rite Byte Rate

The Cache Dirty Pages Percentage parameter represents the amount in percentage of the writecache that has been modified by host write operations and not yet flushed to the disks Reaching100 means that write case is too small and cannot handle the flow of write operations

Checking the Cache Dirty Pages Percentage

Reclaiming Space of Unmapped(Unused) LUNsOver time as servers connected to a SAN get decommissioned administrators find an increasingnumber of unmapped LUNs or volumes that are no longer used by any server These LUNs whileunused still occupy disk space in the disk array Being able to identify such unmapped LUNs andreclaim the disk space uselessly consumed by these LUNs will help administrators avoid unnecessaryupgrades and extensions of their disk arrays

56Reporting a Disk Space Consumption

BMC Performance Manager Express for EMC Disk Arrays

Version 2001

Reporting a Disk SpaceConsumptionMaking sure that a disk array has enough remaining disk space available is critical for severalreasons

middot SAN administrators want to make sure to be able to provision disk space for new servers whenrequested as quickly as possible

middot The disk array itself may need additional disk space for specific features to work properly likeautomatic snapshots mirroring etc

middot If thin provisioning is used the remaining disk space becomes dramatically critical since theinability to allocate additional space to a LUN when requested by the subscriber host will lead tocatastrophic data loss and corruption

The disk space used is permanently monitored for each storage pool The Subscribed Capacityparameter of the Pool class represents the amount of disk space that has been made available tothe subscriber hosts or in other words the amount of disk space that is seen by the serversconnected to disk array

The Consumed Capacity parameter of the SEN_EMC_STORAGEPOOLS class represents the actualspace usage in the storage pool For thin pools (when thin provisioning is enabled on the disk array)this value is normally lower than the Subscribed Capacity as it is the main purpose of thinprovisioning For traditional pools the Consumed Capacity parameters has the same value as theSubscribed Capacity parameter as the entirety of the subscribed disk space is fully allocated inthe storage pool

The Consumed Capacity Percentage parameter is the most critical one as a storage pool usagenearing 100 means that SAN administrators will not be able to create new LUNs in the storagepool By default no alarm or warning threshold is set on this parameter as the fullness of a storagepool may be a normal situation However you can set alert thresholds on this parameter as it fitsyour needs

57Reporting a Disk Space Consumption

Managing Baselines and KeyPerformance IndicatorsIn order to facilitate the detection of abnormalities on your monitored environment BMCProactiveNet calculates baselines per parameter (metrics or attributes) based on values collectedover a specified period of time to determine a normal operating range When the collected values forthese parameters are out of range an alert is triggered

Some parameters are identified by default as Key Performance Indicators and therefore automaticallyincluded in the base lining calculation

42Managing Baselines and Key PerformanceIndicators

BMC Performance Manager Express for EMC Disk Arrays

Version 2001

Managing baselines

The baseline is the expected normal operating range for a metric or attribute of a monitor

The baseline is calculated by collecting the values for a monitorrsquos attributes and metrics over aspecified time period and establishing a low baseline value (consisting of the 10th percentile of all thevalues for a given time period) and a high baseline value (consisting of the 90th percentile of all thevalues for a given time period) taking a weighted average of these values over time A higher weightis given to the latest data being factored into the baseline average The accuracy of the baselineimproves over time

Requirements for baseline generation

For baselines to be generated for an attribute that abnormality threshold means that the thresholdexists and is not suppressed Additionally if the Key Performance Indicator (KPI) mode is active only those attributes that have anactive abnormality threshold and are also KPI attributes will have baselines generated for them

Absolute thresholds (with outside baseline) or signature thresholds do not satisfy these requirements

Managing Key Performance Indicators

The KPI attribute of a parameter can be activated or deactivated manually through the BMCProactiveNet Administration Console In this PM some parameters or attributes have beendesignated as important indicators of performance (KPIs) We do not recommend that these defaultsettings are modified

However advanced users may activate or deactivate KPIs from the BMC ProactiveNet AdministrationConsole

To add or remove Key Performance Indicator (KPI) attributes for amonitor type

1 In the Administration Console from the menu bar choose Tools gt KPI AdministrationThe KPI Administration dialog box is displayed

2 From the Monitor Type list choose the monitor type for which you want to add or remove KPIattributes A list of attributes for the selected monitor type is displayed

3 In the KPI column for the attributes that you want to add or remove as Key PerformanceIndicators

middot select the KPI check box to add the corresponding attribute as a KPI

middot deselect the KPI check box to remove the corresponding attribute from the KPIs for thatmonitor type

For complete and detailed information on this procedure please refer to the BMC ProactiveNet documentation availablefrom BMC Web site

BMC Performance Manager Express for EMC Disk Arrays

Version 2001

BMC Performance Manager Express for EMC Disk Arrays monitors all of the performance metrics andusage statistics of your EMC disk arrays such as file disk space usage storage controller utilizationIOs on the diskscontrollersvolumes etc It continuously monitors the activity of each array and isalso able to build reports on past utilization statistics

To setup a complete monitoring of the array we strongly recommend you to also use BMCPerformance Manager Express for Hardware that covers all the physical aspect of the EMC diskarrays (status of the disks ports temperature power supplies power consumption etc)

This chapter explains how to use each monitoring tool ie a separate application class within theBMC Performance Manager Express for EMC Disk Arrays by Sentry Software solution

BMC Performance Manager Express for EMC Disk Arrays is a Performance Manager specifically designedfor BMC Portal consequently it uses the same common features and procedures of BMCreg Portal Thisdocument assumes that the user knows how to use the Portal and therefore explains procedures onlyrelated to BMC Performance Manager Express for EMC Disk Arrays and not on how to add ElementsElement Profiles etc Please refer to the BMC Portal documentation for details on how to use the Portal

Checking Available Spare Disks

To avoid any loss of critical data it is essential for a disk array to always maintain a pool of sparedisks that can replace the faulty disk when a disk failure occurs A disk array without any left sparedisk will not be able to keep the level of data safety and performance in case of a disk failure

The Spare Disk Count parameter of the SEN_EMC_ARRAY class reports the number of spare disksavailable for each disk array monitored with the solution By default a warning is triggered when nospare disk is available (Spare Disk Count is set to zero)

Verifying the Number of Available Spare Disks in Your EMC Disk Arrays

49Checking Available Spare Disks

BMC Performance Manager Express for EMC Disk Arrays

Version 2001

1 Select an element group in the tree view (the main Infrastructure group for example)

2 Click the Reports tab Create a report for the last 24 hours bottom 50 values of the Array|Spare Disk Count parameter of the EMC Disk Arrays application class for the BMC PerformanceManager Express for EMC Disk Arrays by Sentry Software solution

Detecting OversubscriptionSituations (Thin Provisioning)We call an oversubscription situation when

1 The storage pool is configured for thin provisioning (ldquothin storage poolrdquo)

2 The storage pool is oversubscribed ie the total disk space visible to the hosts (subscribers) isgreater than its actual capacity (this situation is normal for a thin pool since it is its very purpose)

3 The storage pool actual consumed capacity is nearing 100

Such situation is highly critical because the inability to allocate additional space to a LUN whenrequested by the subscriber host will lead to catastrophic data loss and corruption

When the conditions described above are met the solution sets the Oversubscription Situationparameter to 1 automatically raising a warning By default the warning for OversubscriptionSituation is issued when the Consumed Capacity Percentage parameter goes above 100 Thisthreshold can be configured in the input properties of the solution

50Detecting Oversubscription Situations (ThinProvisioning)

BMC Performance Manager Express for EMC Disk Arrays

Version 2001

Configuring Oversubscription Threshold

1 Click the EMC Disk Arrays icon and then the Configure tab

2 Edit the Oversubscription Situation Threshold () property to the appropriate value Whenthe Oversubscription Situation parameter triggers a warning it is highly recommended thatthe SAN administrators add capacity to the storage pool as soon as possible

Diagnosing Slow LUNs

If a system administrator complains that his servers are experiencing slow IOs performance and thatit is caused by the SAN you may want to verify the actual response time of the LUNs the server isrelying on

The Response Time parameter of the SEN_EMC_VOLUME class represents the average time it tookto complete the read and write operations on the LUN during the collection interval Typically theaverage response time is below 10 milliseconds You may also want to compare this value to theresponse time of the other LUNs to see whether one server is really getting worse IO performancethan another

Volume - Response Time Parameter

If the response time is low you will need to check the amount of data that is written and read onthis LUN The bad performance may simply be due to an abnormally large amount of data to processOtherwise the problem is maybe between the disk array and the server in the fiber links

51Enabling the Debug Mode

BMC Performance Manager Express for EMC Disk Arrays

Version 2001

Enabling the Debug Mode

By default BMC Performance Manager Express for EMC Disk Arrays sends only the most criticalinformation warning and error messages to the Application Collection Status parameter Mostoften this information is accurate enough to ensure that BMC Performance Manager Express for EMCDisk Arrays is functioning properly If you encounter an issue and wish to report it to customersupport you will be asked to enable the Debug Mode and provide the debug output to the supportteam

1 In the Configure tab gt under Tasks click Elements

2 Select the Element whose debug output you require and click Edit

3 Scroll down to Application Classes gt click the Application class for which you want toenable the debug mode gt click Edit

4 Select Yes from the drop-down Debug Mode list gt SaveBy default BMC Performance Manager Express for EMC Disk Arrays sends its debug output to RSM_HOMERSM(xx)serverrsmlogsen_debuglog

5 Wait for 15 minutes and then disable the debug mode by selecting No

6 Send the debug file to the support team

Pay attention to the file size -the debug output of BMC Performance Manager Express for EMC Disk Arrays could bevery large if enabled for several days

Identifying the Hosts that canAccess a LUNIn most SAN configurations each LUN belongs to a storage group whose host members are the onlyones authorized to access the LUN This is called LUN masking For each LUN the solution displaysits WWN the storage group to which it belongs to as well as the hosts member of this group Inmost cases identifying the storage group of a LUN is sufficient to recognize the server that is usingit

52Identifying LUNs not Owned by their Normal(Default) Storage Processor

BMC Performance Manager Express for EMC Disk Arrays

Version 2001

Identifying LUNs not Owned bytheir Normal (Default) StorageProcessorThe Owning Storage Processor parameter reports the name of the controller that handles IOsfor each LUN If a LUN is not currently handled by its normal (default) storage processors the nameof the default controller will be indicated as SP_B (default SP_A)rdquo

To identify LUNs that are not owned by their normal storage processor you simply need to list the Volume objects where the Owning Storage Processor parameter contains the string Default

Identifying Most Busy LUNs

To identify the LUNs that generate the most traffic on the disk array use the Read Byte Rate andWrite Byte Rate parameters of the LUN class that expose the data throughput for each LUN Usethese parameters to report on the total data traffic (per hour or per day) on each LUN in GB

To make sure that traffic is displayed cumulatively per hour select a time window of at least 12 hours in the graphwindow select at least 7 days to visualize per day cumulative data

1 In the Status tab click the Volume for which you need to check the LUNs activity then expandthe LUNs object to display the ReadWrite Byte Rate parameters

53Identifying Most Busy LUNs

2 Click the History icon to automatically display a graph that shows the ReadWrite Byte Ratevalues collected for a selected parameter during the previous six hours You can customize thechart and table to show parameter history for different time periods

54Identifying Most Busy LUNs

BMC Performance Manager Express for EMC Disk Arrays

Version 2001

View ing a LUNs ReadW rite Byte Rate as a graph

Identifying a Storage Processor(Controllers) OverloadTo visualize the activity of a controller in an EMC disk array use the Processor Utilizationparameter of the SEN_EMC_CONTROLLER class A warning is issued when the processor utilizationgoes too high which means that the controllers cannot keep up with the load on the disk array It isthen important to identify what is overloading the controllers

The Response Time parameter of the SEN_EMC_CONTROLLER class represents the average time ittook the controller to process the read and write requests of the hosts The higher the ResponseTime goes the slower IOs the servers will get By default the solution triggers a warning when thecontroller takes more than 10 milliseconds on average to complete the IO requests and an alarmwhen the response time reaches 100 milliseconds

Monitoring the Efficiency of theCaching MechanismEach controller in an EMC disk array can be configured to use a specified amount of memory tocache the read andor write operations The solution reports the amount of memory configured byeach controller for the read and write operations

The Write Flush Byte Rate represents the rate in MBsec at which data is committed to the disk(ie physically written) This value is to be compared with the Write Byte Rate of the disk array

55Monitoring the Efficiency of the CachingMechanism

BMC Performance Manager Express for EMC Disk Arrays

Version 2001

Comparing W rite Flush Byte Rate w ith W rite Byte Rate

The Cache Dirty Pages Percentage parameter represents the amount in percentage of the writecache that has been modified by host write operations and not yet flushed to the disks Reaching100 means that write case is too small and cannot handle the flow of write operations

Checking the Cache Dirty Pages Percentage

Reclaiming Space of Unmapped(Unused) LUNsOver time as servers connected to a SAN get decommissioned administrators find an increasingnumber of unmapped LUNs or volumes that are no longer used by any server These LUNs whileunused still occupy disk space in the disk array Being able to identify such unmapped LUNs andreclaim the disk space uselessly consumed by these LUNs will help administrators avoid unnecessaryupgrades and extensions of their disk arrays

56Reporting a Disk Space Consumption

BMC Performance Manager Express for EMC Disk Arrays

Version 2001

Reporting a Disk SpaceConsumptionMaking sure that a disk array has enough remaining disk space available is critical for severalreasons

middot SAN administrators want to make sure to be able to provision disk space for new servers whenrequested as quickly as possible

middot The disk array itself may need additional disk space for specific features to work properly likeautomatic snapshots mirroring etc

middot If thin provisioning is used the remaining disk space becomes dramatically critical since theinability to allocate additional space to a LUN when requested by the subscriber host will lead tocatastrophic data loss and corruption

The disk space used is permanently monitored for each storage pool The Subscribed Capacityparameter of the Pool class represents the amount of disk space that has been made available tothe subscriber hosts or in other words the amount of disk space that is seen by the serversconnected to disk array

The Consumed Capacity parameter of the SEN_EMC_STORAGEPOOLS class represents the actualspace usage in the storage pool For thin pools (when thin provisioning is enabled on the disk array)this value is normally lower than the Subscribed Capacity as it is the main purpose of thinprovisioning For traditional pools the Consumed Capacity parameters has the same value as theSubscribed Capacity parameter as the entirety of the subscribed disk space is fully allocated inthe storage pool

The Consumed Capacity Percentage parameter is the most critical one as a storage pool usagenearing 100 means that SAN administrators will not be able to create new LUNs in the storagepool By default no alarm or warning threshold is set on this parameter as the fullness of a storagepool may be a normal situation However you can set alert thresholds on this parameter as it fitsyour needs

57Reporting a Disk Space Consumption

Reporting the Total Traffic on anHourly or Daily BasisBMC Performance Manager Express for EMC Disk Arrays not only monitors the traffic and activity ofthe disk array controllers LUNs and physical disks in MBsec but also in GB per hour or per day Theexact amount of data that was read or written to the disk array LUN or physical disk is calculated foreach hour of the day and each day of the week

Each data rate parameter in MBsec is accompanied by a non-rate one in GB These parameters areldquocumulativerdquo their instantaneous value has no meaning and they need to be visualized in a longperiod of time (instead of Read Byte Rate or Write Byte Rate)

Setting thresholds

Whenever relevant BMC Performance Manager Express for EMC Disk Arrays automatically setsthresholds for parameters If you prefer a more fault-tolerant monitoring you can modify thethresholds of each parameter through the Configure tab gt Edit Thresholds

It is strongly recommended to wait for all the storage objects to be discovered before setting threshold values to avoidhaving to enter thresholds for each occurrence of the application class

To modify the parameter thresholds of several storage objects of an element

60Setting thresholds

BMC Performance Manager Express for EMC Disk Arrays

Version 2001

1 In the Configure tab click on the Storage (ltplatformgt) or the instance icon gt Edit

Thresholds Properties and Credentials

Any modification to the thresholds or any other properties of elements created using the Element

Profile mode is to be done using the Element Profile route or by clicking Override Profile

2 Uncheck the Warning and Alarm boxes for all the parameters for which you want to disablethe alert conditions

Alerts are displayed by the parameter whose thresholds are modified

Viewing the Overall Activity of aDisk ArrayIn order to visualize the activity of a disk array use the Read Byte Rate and Write Byte Rate ofthe SEN_EMC_ARRAY class These parameters represent the overall traffic in megabytes per secondfor each monitored array or more precisely each EMC disk array that is exposed through the EMCSMI-S Provider (see the EMC_SMI-S_Provider section of the Installation Guide for more informationabout the EMC SMI-S Provider)

62Viewing the Overall Activity of a Disk Array

BMC Performance Manager Express for EMC Disk Arrays

Managing Baselines and KeyPerformance IndicatorsIn order to facilitate the detection of abnormalities on your monitored environment BMCProactiveNet calculates baselines per parameter (metrics or attributes) based on values collectedover a specified period of time to determine a normal operating range When the collected values forthese parameters are out of range an alert is triggered

Some parameters are identified by default as Key Performance Indicators and therefore automaticallyincluded in the base lining calculation

42Managing Baselines and Key PerformanceIndicators

BMC Performance Manager Express for EMC Disk Arrays

Version 2001

Managing baselines

The baseline is the expected normal operating range for a metric or attribute of a monitor

The baseline is calculated by collecting the values for a monitorrsquos attributes and metrics over aspecified time period and establishing a low baseline value (consisting of the 10th percentile of all thevalues for a given time period) and a high baseline value (consisting of the 90th percentile of all thevalues for a given time period) taking a weighted average of these values over time A higher weightis given to the latest data being factored into the baseline average The accuracy of the baselineimproves over time

Requirements for baseline generation

For baselines to be generated for an attribute that abnormality threshold means that the thresholdexists and is not suppressed Additionally if the Key Performance Indicator (KPI) mode is active only those attributes that have anactive abnormality threshold and are also KPI attributes will have baselines generated for them

Absolute thresholds (with outside baseline) or signature thresholds do not satisfy these requirements

Managing Key Performance Indicators

The KPI attribute of a parameter can be activated or deactivated manually through the BMCProactiveNet Administration Console In this PM some parameters or attributes have beendesignated as important indicators of performance (KPIs) We do not recommend that these defaultsettings are modified

However advanced users may activate or deactivate KPIs from the BMC ProactiveNet AdministrationConsole

To add or remove Key Performance Indicator (KPI) attributes for amonitor type

1 In the Administration Console from the menu bar choose Tools gt KPI AdministrationThe KPI Administration dialog box is displayed

2 From the Monitor Type list choose the monitor type for which you want to add or remove KPIattributes A list of attributes for the selected monitor type is displayed

3 In the KPI column for the attributes that you want to add or remove as Key PerformanceIndicators

middot select the KPI check box to add the corresponding attribute as a KPI

middot deselect the KPI check box to remove the corresponding attribute from the KPIs for thatmonitor type

For complete and detailed information on this procedure please refer to the BMC ProactiveNet documentation availablefrom BMC Web site

To setup a complete monitoring of the array we strongly recommend you to also use BMCPerformance Manager Express for Hardware that covers all the physical aspect of the EMC diskarrays (status of the disks ports temperature power supplies power consumption etc)

This chapter explains how to use each monitoring tool ie a separate application class within theBMC Performance Manager Express for EMC Disk Arrays by Sentry Software solution

BMC Performance Manager Express for EMC Disk Arrays is a Performance Manager specifically designedfor BMC Portal consequently it uses the same common features and procedures of BMCreg Portal Thisdocument assumes that the user knows how to use the Portal and therefore explains procedures onlyrelated to BMC Performance Manager Express for EMC Disk Arrays and not on how to add ElementsElement Profiles etc Please refer to the BMC Portal documentation for details on how to use the Portal

Checking Available Spare Disks

To avoid any loss of critical data it is essential for a disk array to always maintain a pool of sparedisks that can replace the faulty disk when a disk failure occurs A disk array without any left sparedisk will not be able to keep the level of data safety and performance in case of a disk failure

The Spare Disk Count parameter of the SEN_EMC_ARRAY class reports the number of spare disksavailable for each disk array monitored with the solution By default a warning is triggered when nospare disk is available (Spare Disk Count is set to zero)

Verifying the Number of Available Spare Disks in Your EMC Disk Arrays

49Checking Available Spare Disks

BMC Performance Manager Express for EMC Disk Arrays

Version 2001

1 Select an element group in the tree view (the main Infrastructure group for example)

2 Click the Reports tab Create a report for the last 24 hours bottom 50 values of the Array|Spare Disk Count parameter of the EMC Disk Arrays application class for the BMC PerformanceManager Express for EMC Disk Arrays by Sentry Software solution

Detecting OversubscriptionSituations (Thin Provisioning)We call an oversubscription situation when

1 The storage pool is configured for thin provisioning (ldquothin storage poolrdquo)

2 The storage pool is oversubscribed ie the total disk space visible to the hosts (subscribers) isgreater than its actual capacity (this situation is normal for a thin pool since it is its very purpose)

3 The storage pool actual consumed capacity is nearing 100

Such situation is highly critical because the inability to allocate additional space to a LUN whenrequested by the subscriber host will lead to catastrophic data loss and corruption

When the conditions described above are met the solution sets the Oversubscription Situationparameter to 1 automatically raising a warning By default the warning for OversubscriptionSituation is issued when the Consumed Capacity Percentage parameter goes above 100 Thisthreshold can be configured in the input properties of the solution

50Detecting Oversubscription Situations (ThinProvisioning)

BMC Performance Manager Express for EMC Disk Arrays

Version 2001

Configuring Oversubscription Threshold

1 Click the EMC Disk Arrays icon and then the Configure tab

2 Edit the Oversubscription Situation Threshold () property to the appropriate value Whenthe Oversubscription Situation parameter triggers a warning it is highly recommended thatthe SAN administrators add capacity to the storage pool as soon as possible

Diagnosing Slow LUNs

If a system administrator complains that his servers are experiencing slow IOs performance and thatit is caused by the SAN you may want to verify the actual response time of the LUNs the server isrelying on

The Response Time parameter of the SEN_EMC_VOLUME class represents the average time it tookto complete the read and write operations on the LUN during the collection interval Typically theaverage response time is below 10 milliseconds You may also want to compare this value to theresponse time of the other LUNs to see whether one server is really getting worse IO performancethan another

Volume - Response Time Parameter

If the response time is low you will need to check the amount of data that is written and read onthis LUN The bad performance may simply be due to an abnormally large amount of data to processOtherwise the problem is maybe between the disk array and the server in the fiber links

51Enabling the Debug Mode

BMC Performance Manager Express for EMC Disk Arrays

Version 2001

Enabling the Debug Mode

By default BMC Performance Manager Express for EMC Disk Arrays sends only the most criticalinformation warning and error messages to the Application Collection Status parameter Mostoften this information is accurate enough to ensure that BMC Performance Manager Express for EMCDisk Arrays is functioning properly If you encounter an issue and wish to report it to customersupport you will be asked to enable the Debug Mode and provide the debug output to the supportteam

1 In the Configure tab gt under Tasks click Elements

2 Select the Element whose debug output you require and click Edit

3 Scroll down to Application Classes gt click the Application class for which you want toenable the debug mode gt click Edit

4 Select Yes from the drop-down Debug Mode list gt SaveBy default BMC Performance Manager Express for EMC Disk Arrays sends its debug output to RSM_HOMERSM(xx)serverrsmlogsen_debuglog

5 Wait for 15 minutes and then disable the debug mode by selecting No

6 Send the debug file to the support team

Pay attention to the file size -the debug output of BMC Performance Manager Express for EMC Disk Arrays could bevery large if enabled for several days

Identifying the Hosts that canAccess a LUNIn most SAN configurations each LUN belongs to a storage group whose host members are the onlyones authorized to access the LUN This is called LUN masking For each LUN the solution displaysits WWN the storage group to which it belongs to as well as the hosts member of this group Inmost cases identifying the storage group of a LUN is sufficient to recognize the server that is usingit

52Identifying LUNs not Owned by their Normal(Default) Storage Processor

BMC Performance Manager Express for EMC Disk Arrays

Version 2001

Identifying LUNs not Owned bytheir Normal (Default) StorageProcessorThe Owning Storage Processor parameter reports the name of the controller that handles IOsfor each LUN If a LUN is not currently handled by its normal (default) storage processors the nameof the default controller will be indicated as SP_B (default SP_A)rdquo

To identify LUNs that are not owned by their normal storage processor you simply need to list the Volume objects where the Owning Storage Processor parameter contains the string Default

Identifying Most Busy LUNs

To identify the LUNs that generate the most traffic on the disk array use the Read Byte Rate andWrite Byte Rate parameters of the LUN class that expose the data throughput for each LUN Usethese parameters to report on the total data traffic (per hour or per day) on each LUN in GB

To make sure that traffic is displayed cumulatively per hour select a time window of at least 12 hours in the graphwindow select at least 7 days to visualize per day cumulative data

1 In the Status tab click the Volume for which you need to check the LUNs activity then expandthe LUNs object to display the ReadWrite Byte Rate parameters

Version 2001

View ing a LUNs ReadW rite Byte Rate as a graph

Identifying a Storage Processor(Controllers) OverloadTo visualize the activity of a controller in an EMC disk array use the Processor Utilizationparameter of the SEN_EMC_CONTROLLER class A warning is issued when the processor utilizationgoes too high which means that the controllers cannot keep up with the load on the disk array It isthen important to identify what is overloading the controllers

The Response Time parameter of the SEN_EMC_CONTROLLER class represents the average time ittook the controller to process the read and write requests of the hosts The higher the ResponseTime goes the slower IOs the servers will get By default the solution triggers a warning when thecontroller takes more than 10 milliseconds on average to complete the IO requests and an alarmwhen the response time reaches 100 milliseconds

Monitoring the Efficiency of theCaching MechanismEach controller in an EMC disk array can be configured to use a specified amount of memory tocache the read andor write operations The solution reports the amount of memory configured byeach controller for the read and write operations

The Write Flush Byte Rate represents the rate in MBsec at which data is committed to the disk(ie physically written) This value is to be compared with the Write Byte Rate of the disk array

55Monitoring the Efficiency of the CachingMechanism

BMC Performance Manager Express for EMC Disk Arrays

Version 2001

Comparing W rite Flush Byte Rate w ith W rite Byte Rate

The Cache Dirty Pages Percentage parameter represents the amount in percentage of the writecache that has been modified by host write operations and not yet flushed to the disks Reaching100 means that write case is too small and cannot handle the flow of write operations

Checking the Cache Dirty Pages Percentage

Reclaiming Space of Unmapped(Unused) LUNsOver time as servers connected to a SAN get decommissioned administrators find an increasingnumber of unmapped LUNs or volumes that are no longer used by any server These LUNs whileunused still occupy disk space in the disk array Being able to identify such unmapped LUNs andreclaim the disk space uselessly consumed by these LUNs will help administrators avoid unnecessaryupgrades and extensions of their disk arrays

56Reporting a Disk Space Consumption

BMC Performance Manager Express for EMC Disk Arrays

Version 2001

Reporting a Disk SpaceConsumptionMaking sure that a disk array has enough remaining disk space available is critical for severalreasons

middot SAN administrators want to make sure to be able to provision disk space for new servers whenrequested as quickly as possible

middot The disk array itself may need additional disk space for specific features to work properly likeautomatic snapshots mirroring etc

middot If thin provisioning is used the remaining disk space becomes dramatically critical since theinability to allocate additional space to a LUN when requested by the subscriber host will lead tocatastrophic data loss and corruption

The disk space used is permanently monitored for each storage pool The Subscribed Capacityparameter of the Pool class represents the amount of disk space that has been made available tothe subscriber hosts or in other words the amount of disk space that is seen by the serversconnected to disk array

The Consumed Capacity parameter of the SEN_EMC_STORAGEPOOLS class represents the actualspace usage in the storage pool For thin pools (when thin provisioning is enabled on the disk array)this value is normally lower than the Subscribed Capacity as it is the main purpose of thinprovisioning For traditional pools the Consumed Capacity parameters has the same value as theSubscribed Capacity parameter as the entirety of the subscribed disk space is fully allocated inthe storage pool

The Consumed Capacity Percentage parameter is the most critical one as a storage pool usagenearing 100 means that SAN administrators will not be able to create new LUNs in the storagepool By default no alarm or warning threshold is set on this parameter as the fullness of a storagepool may be a normal situation However you can set alert thresholds on this parameter as it fitsyour needs

We strongly recommend that you create a specific adapter for each PM you need to integrate into BMCProactiveNet to enable the update of a single PM independently

Once created and imported the Adapter will be displayed in the Devices folder of the BMCProactiveNet Operations Console

Managing Baselines and KeyPerformance IndicatorsIn order to facilitate the detection of abnormalities on your monitored environment BMCProactiveNet calculates baselines per parameter (metrics or attributes) based on values collectedover a specified period of time to determine a normal operating range When the collected values forthese parameters are out of range an alert is triggered

Some parameters are identified by default as Key Performance Indicators and therefore automaticallyincluded in the base lining calculation

42Managing Baselines and Key PerformanceIndicators

BMC Performance Manager Express for EMC Disk Arrays

Version 2001

Managing baselines

The baseline is the expected normal operating range for a metric or attribute of a monitor

The baseline is calculated by collecting the values for a monitorrsquos attributes and metrics over aspecified time period and establishing a low baseline value (consisting of the 10th percentile of all thevalues for a given time period) and a high baseline value (consisting of the 90th percentile of all thevalues for a given time period) taking a weighted average of these values over time A higher weightis given to the latest data being factored into the baseline average The accuracy of the baselineimproves over time

Requirements for baseline generation

For baselines to be generated for an attribute that abnormality threshold means that the thresholdexists and is not suppressed Additionally if the Key Performance Indicator (KPI) mode is active only those attributes that have anactive abnormality threshold and are also KPI attributes will have baselines generated for them

Absolute thresholds (with outside baseline) or signature thresholds do not satisfy these requirements

Managing Key Performance Indicators

The KPI attribute of a parameter can be activated or deactivated manually through the BMCProactiveNet Administration Console In this PM some parameters or attributes have beendesignated as important indicators of performance (KPIs) We do not recommend that these defaultsettings are modified

However advanced users may activate or deactivate KPIs from the BMC ProactiveNet AdministrationConsole

To add or remove Key Performance Indicator (KPI) attributes for amonitor type

1 In the Administration Console from the menu bar choose Tools gt KPI AdministrationThe KPI Administration dialog box is displayed

2 From the Monitor Type list choose the monitor type for which you want to add or remove KPIattributes A list of attributes for the selected monitor type is displayed

3 In the KPI column for the attributes that you want to add or remove as Key PerformanceIndicators

middot select the KPI check box to add the corresponding attribute as a KPI

middot deselect the KPI check box to remove the corresponding attribute from the KPIs for thatmonitor type

For complete and detailed information on this procedure please refer to the BMC ProactiveNet documentation availablefrom BMC Web site

BMC Performance Manager Express for EMC Disk Arrays

Version 2001

BMC Performance Manager Express for EMC Disk Arrays monitors all of the performance metrics andusage statistics of your EMC disk arrays such as file disk space usage storage controller utilizationIOs on the diskscontrollersvolumes etc It continuously monitors the activity of each array and isalso able to build reports on past utilization statistics

To setup a complete monitoring of the array we strongly recommend you to also use BMCPerformance Manager Express for Hardware that covers all the physical aspect of the EMC diskarrays (status of the disks ports temperature power supplies power consumption etc)

This chapter explains how to use each monitoring tool ie a separate application class within theBMC Performance Manager Express for EMC Disk Arrays by Sentry Software solution

BMC Performance Manager Express for EMC Disk Arrays is a Performance Manager specifically designedfor BMC Portal consequently it uses the same common features and procedures of BMCreg Portal Thisdocument assumes that the user knows how to use the Portal and therefore explains procedures onlyrelated to BMC Performance Manager Express for EMC Disk Arrays and not on how to add ElementsElement Profiles etc Please refer to the BMC Portal documentation for details on how to use the Portal

Checking Available Spare Disks

To avoid any loss of critical data it is essential for a disk array to always maintain a pool of sparedisks that can replace the faulty disk when a disk failure occurs A disk array without any left sparedisk will not be able to keep the level of data safety and performance in case of a disk failure

The Spare Disk Count parameter of the SEN_EMC_ARRAY class reports the number of spare disksavailable for each disk array monitored with the solution By default a warning is triggered when nospare disk is available (Spare Disk Count is set to zero)

Verifying the Number of Available Spare Disks in Your EMC Disk Arrays

49Checking Available Spare Disks

BMC Performance Manager Express for EMC Disk Arrays

Version 2001

1 Select an element group in the tree view (the main Infrastructure group for example)

2 Click the Reports tab Create a report for the last 24 hours bottom 50 values of the Array|Spare Disk Count parameter of the EMC Disk Arrays application class for the BMC PerformanceManager Express for EMC Disk Arrays by Sentry Software solution

Report ndash Available Spare Disks

Detecting OversubscriptionSituations (Thin Provisioning)We call an oversubscription situation when

1 The storage pool is configured for thin provisioning (ldquothin storage poolrdquo)

2 The storage pool is oversubscribed ie the total disk space visible to the hosts (subscribers) isgreater than its actual capacity (this situation is normal for a thin pool since it is its very purpose)

3 The storage pool actual consumed capacity is nearing 100

Such situation is highly critical because the inability to allocate additional space to a LUN whenrequested by the subscriber host will lead to catastrophic data loss and corruption

When the conditions described above are met the solution sets the Oversubscription Situationparameter to 1 automatically raising a warning By default the warning for OversubscriptionSituation is issued when the Consumed Capacity Percentage parameter goes above 100 Thisthreshold can be configured in the input properties of the solution

50Detecting Oversubscription Situations (ThinProvisioning)

BMC Performance Manager Express for EMC Disk Arrays

Version 2001

Configuring Oversubscription Threshold

1 Click the EMC Disk Arrays icon and then the Configure tab

2 Edit the Oversubscription Situation Threshold () property to the appropriate value Whenthe Oversubscription Situation parameter triggers a warning it is highly recommended thatthe SAN administrators add capacity to the storage pool as soon as possible

Diagnosing Slow LUNs

If a system administrator complains that his servers are experiencing slow IOs performance and thatit is caused by the SAN you may want to verify the actual response time of the LUNs the server isrelying on

The Response Time parameter of the SEN_EMC_VOLUME class represents the average time it tookto complete the read and write operations on the LUN during the collection interval Typically theaverage response time is below 10 milliseconds You may also want to compare this value to theresponse time of the other LUNs to see whether one server is really getting worse IO performancethan another

Volume - Response Time Parameter

If the response time is low you will need to check the amount of data that is written and read onthis LUN The bad performance may simply be due to an abnormally large amount of data to processOtherwise the problem is maybe between the disk array and the server in the fiber links

51Enabling the Debug Mode

BMC Performance Manager Express for EMC Disk Arrays

Version 2001

Enabling the Debug Mode

By default BMC Performance Manager Express for EMC Disk Arrays sends only the most criticalinformation warning and error messages to the Application Collection Status parameter Mostoften this information is accurate enough to ensure that BMC Performance Manager Express for EMCDisk Arrays is functioning properly If you encounter an issue and wish to report it to customersupport you will be asked to enable the Debug Mode and provide the debug output to the supportteam

1 In the Configure tab gt under Tasks click Elements

2 Select the Element whose debug output you require and click Edit

3 Scroll down to Application Classes gt click the Application class for which you want toenable the debug mode gt click Edit

4 Select Yes from the drop-down Debug Mode list gt SaveBy default BMC Performance Manager Express for EMC Disk Arrays sends its debug output to RSM_HOMERSM(xx)serverrsmlogsen_debuglog

5 Wait for 15 minutes and then disable the debug mode by selecting No

6 Send the debug file to the support team

Pay attention to the file size -the debug output of BMC Performance Manager Express for EMC Disk Arrays could bevery large if enabled for several days

Identifying the Hosts that canAccess a LUNIn most SAN configurations each LUN belongs to a storage group whose host members are the onlyones authorized to access the LUN This is called LUN masking For each LUN the solution displaysits WWN the storage group to which it belongs to as well as the hosts member of this group Inmost cases identifying the storage group of a LUN is sufficient to recognize the server that is usingit

52Identifying LUNs not Owned by their Normal(Default) Storage Processor

BMC Performance Manager Express for EMC Disk Arrays

Version 2001

Identifying LUNs not Owned bytheir Normal (Default) StorageProcessorThe Owning Storage Processor parameter reports the name of the controller that handles IOsfor each LUN If a LUN is not currently handled by its normal (default) storage processors the nameof the default controller will be indicated as SP_B (default SP_A)rdquo

To identify LUNs that are not owned by their normal storage processor you simply need to list the Volume objects where the Owning Storage Processor parameter contains the string Default

Identifying Most Busy LUNs

To identify the LUNs that generate the most traffic on the disk array use the Read Byte Rate andWrite Byte Rate parameters of the LUN class that expose the data throughput for each LUN Usethese parameters to report on the total data traffic (per hour or per day) on each LUN in GB

To make sure that traffic is displayed cumulatively per hour select a time window of at least 12 hours in the graphwindow select at least 7 days to visualize per day cumulative data

1 In the Status tab click the Volume for which you need to check the LUNs activity then expandthe LUNs object to display the ReadWrite Byte Rate parameters

53Identifying Most Busy LUNs

Version 2001

View ing a LUNs ReadW rite Byte Rate as a graph

Identifying a Storage Processor(Controllers) OverloadTo visualize the activity of a controller in an EMC disk array use the Processor Utilizationparameter of the SEN_EMC_CONTROLLER class A warning is issued when the processor utilizationgoes too high which means that the controllers cannot keep up with the load on the disk array It isthen important to identify what is overloading the controllers

The Response Time parameter of the SEN_EMC_CONTROLLER class represents the average time ittook the controller to process the read and write requests of the hosts The higher the ResponseTime goes the slower IOs the servers will get By default the solution triggers a warning when thecontroller takes more than 10 milliseconds on average to complete the IO requests and an alarmwhen the response time reaches 100 milliseconds

Monitoring the Efficiency of theCaching MechanismEach controller in an EMC disk array can be configured to use a specified amount of memory tocache the read andor write operations The solution reports the amount of memory configured byeach controller for the read and write operations

The Write Flush Byte Rate represents the rate in MBsec at which data is committed to the disk(ie physically written) This value is to be compared with the Write Byte Rate of the disk array

55Monitoring the Efficiency of the CachingMechanism

BMC Performance Manager Express for EMC Disk Arrays

Version 2001

Comparing W rite Flush Byte Rate w ith W rite Byte Rate

The Cache Dirty Pages Percentage parameter represents the amount in percentage of the writecache that has been modified by host write operations and not yet flushed to the disks Reaching100 means that write case is too small and cannot handle the flow of write operations

Checking the Cache Dirty Pages Percentage

Reclaiming Space of Unmapped(Unused) LUNsOver time as servers connected to a SAN get decommissioned administrators find an increasingnumber of unmapped LUNs or volumes that are no longer used by any server These LUNs whileunused still occupy disk space in the disk array Being able to identify such unmapped LUNs andreclaim the disk space uselessly consumed by these LUNs will help administrators avoid unnecessaryupgrades and extensions of their disk arrays

56Reporting a Disk Space Consumption

BMC Performance Manager Express for EMC Disk Arrays

Version 2001

Reporting a Disk SpaceConsumptionMaking sure that a disk array has enough remaining disk space available is critical for severalreasons

middot SAN administrators want to make sure to be able to provision disk space for new servers whenrequested as quickly as possible

middot The disk array itself may need additional disk space for specific features to work properly likeautomatic snapshots mirroring etc

middot If thin provisioning is used the remaining disk space becomes dramatically critical since theinability to allocate additional space to a LUN when requested by the subscriber host will lead tocatastrophic data loss and corruption

The disk space used is permanently monitored for each storage pool The Subscribed Capacityparameter of the Pool class represents the amount of disk space that has been made available tothe subscriber hosts or in other words the amount of disk space that is seen by the serversconnected to disk array

The Consumed Capacity parameter of the SEN_EMC_STORAGEPOOLS class represents the actualspace usage in the storage pool For thin pools (when thin provisioning is enabled on the disk array)this value is normally lower than the Subscribed Capacity as it is the main purpose of thinprovisioning For traditional pools the Consumed Capacity parameters has the same value as theSubscribed Capacity parameter as the entirety of the subscribed disk space is fully allocated inthe storage pool

The Consumed Capacity Percentage parameter is the most critical one as a storage pool usagenearing 100 means that SAN administrators will not be able to create new LUNs in the storagepool By default no alarm or warning threshold is set on this parameter as the fullness of a storagepool may be a normal situation However you can set alert thresholds on this parameter as it fitsyour needs

Managing Baselines and KeyPerformance IndicatorsIn order to facilitate the detection of abnormalities on your monitored environment BMCProactiveNet calculates baselines per parameter (metrics or attributes) based on values collectedover a specified period of time to determine a normal operating range When the collected values forthese parameters are out of range an alert is triggered

Some parameters are identified by default as Key Performance Indicators and therefore automaticallyincluded in the base lining calculation

42Managing Baselines and Key PerformanceIndicators

BMC Performance Manager Express for EMC Disk Arrays

Version 2001

Managing baselines

The baseline is the expected normal operating range for a metric or attribute of a monitor

The baseline is calculated by collecting the values for a monitorrsquos attributes and metrics over aspecified time period and establishing a low baseline value (consisting of the 10th percentile of all thevalues for a given time period) and a high baseline value (consisting of the 90th percentile of all thevalues for a given time period) taking a weighted average of these values over time A higher weightis given to the latest data being factored into the baseline average The accuracy of the baselineimproves over time

Requirements for baseline generation

For baselines to be generated for an attribute that abnormality threshold means that the thresholdexists and is not suppressed Additionally if the Key Performance Indicator (KPI) mode is active only those attributes that have anactive abnormality threshold and are also KPI attributes will have baselines generated for them

Absolute thresholds (with outside baseline) or signature thresholds do not satisfy these requirements

Managing Key Performance Indicators

The KPI attribute of a parameter can be activated or deactivated manually through the BMCProactiveNet Administration Console In this PM some parameters or attributes have beendesignated as important indicators of performance (KPIs) We do not recommend that these defaultsettings are modified

However advanced users may activate or deactivate KPIs from the BMC ProactiveNet AdministrationConsole

To add or remove Key Performance Indicator (KPI) attributes for amonitor type

1 In the Administration Console from the menu bar choose Tools gt KPI AdministrationThe KPI Administration dialog box is displayed

2 From the Monitor Type list choose the monitor type for which you want to add or remove KPIattributes A list of attributes for the selected monitor type is displayed

3 In the KPI column for the attributes that you want to add or remove as Key PerformanceIndicators

middot select the KPI check box to add the corresponding attribute as a KPI

middot deselect the KPI check box to remove the corresponding attribute from the KPIs for thatmonitor type

For complete and detailed information on this procedure please refer to the BMC ProactiveNet documentation availablefrom BMC Web site

BMC Performance Manager Express for EMC Disk Arrays

Version 2001

BMC Performance Manager Express for EMC Disk Arrays monitors all of the performance metrics andusage statistics of your EMC disk arrays such as file disk space usage storage controller utilizationIOs on the diskscontrollersvolumes etc It continuously monitors the activity of each array and isalso able to build reports on past utilization statistics

To setup a complete monitoring of the array we strongly recommend you to also use BMCPerformance Manager Express for Hardware that covers all the physical aspect of the EMC diskarrays (status of the disks ports temperature power supplies power consumption etc)

This chapter explains how to use each monitoring tool ie a separate application class within theBMC Performance Manager Express for EMC Disk Arrays by Sentry Software solution

BMC Performance Manager Express for EMC Disk Arrays is a Performance Manager specifically designedfor BMC Portal consequently it uses the same common features and procedures of BMCreg Portal Thisdocument assumes that the user knows how to use the Portal and therefore explains procedures onlyrelated to BMC Performance Manager Express for EMC Disk Arrays and not on how to add ElementsElement Profiles etc Please refer to the BMC Portal documentation for details on how to use the Portal

Checking Available Spare Disks

To avoid any loss of critical data it is essential for a disk array to always maintain a pool of sparedisks that can replace the faulty disk when a disk failure occurs A disk array without any left sparedisk will not be able to keep the level of data safety and performance in case of a disk failure

The Spare Disk Count parameter of the SEN_EMC_ARRAY class reports the number of spare disksavailable for each disk array monitored with the solution By default a warning is triggered when nospare disk is available (Spare Disk Count is set to zero)

Verifying the Number of Available Spare Disks in Your EMC Disk Arrays

49Checking Available Spare Disks

BMC Performance Manager Express for EMC Disk Arrays

Version 2001

1 Select an element group in the tree view (the main Infrastructure group for example)

2 Click the Reports tab Create a report for the last 24 hours bottom 50 values of the Array|Spare Disk Count parameter of the EMC Disk Arrays application class for the BMC PerformanceManager Express for EMC Disk Arrays by Sentry Software solution

Detecting OversubscriptionSituations (Thin Provisioning)We call an oversubscription situation when

1 The storage pool is configured for thin provisioning (ldquothin storage poolrdquo)

2 The storage pool is oversubscribed ie the total disk space visible to the hosts (subscribers) isgreater than its actual capacity (this situation is normal for a thin pool since it is its very purpose)

3 The storage pool actual consumed capacity is nearing 100

Such situation is highly critical because the inability to allocate additional space to a LUN whenrequested by the subscriber host will lead to catastrophic data loss and corruption

When the conditions described above are met the solution sets the Oversubscription Situationparameter to 1 automatically raising a warning By default the warning for OversubscriptionSituation is issued when the Consumed Capacity Percentage parameter goes above 100 Thisthreshold can be configured in the input properties of the solution

50Detecting Oversubscription Situations (ThinProvisioning)

BMC Performance Manager Express for EMC Disk Arrays

Version 2001

Configuring Oversubscription Threshold

1 Click the EMC Disk Arrays icon and then the Configure tab

2 Edit the Oversubscription Situation Threshold () property to the appropriate value Whenthe Oversubscription Situation parameter triggers a warning it is highly recommended thatthe SAN administrators add capacity to the storage pool as soon as possible

Diagnosing Slow LUNs

If a system administrator complains that his servers are experiencing slow IOs performance and thatit is caused by the SAN you may want to verify the actual response time of the LUNs the server isrelying on

The Response Time parameter of the SEN_EMC_VOLUME class represents the average time it tookto complete the read and write operations on the LUN during the collection interval Typically theaverage response time is below 10 milliseconds You may also want to compare this value to theresponse time of the other LUNs to see whether one server is really getting worse IO performancethan another

Volume - Response Time Parameter

If the response time is low you will need to check the amount of data that is written and read onthis LUN The bad performance may simply be due to an abnormally large amount of data to processOtherwise the problem is maybe between the disk array and the server in the fiber links

51Enabling the Debug Mode

BMC Performance Manager Express for EMC Disk Arrays

Version 2001

Enabling the Debug Mode

By default BMC Performance Manager Express for EMC Disk Arrays sends only the most criticalinformation warning and error messages to the Application Collection Status parameter Mostoften this information is accurate enough to ensure that BMC Performance Manager Express for EMCDisk Arrays is functioning properly If you encounter an issue and wish to report it to customersupport you will be asked to enable the Debug Mode and provide the debug output to the supportteam

1 In the Configure tab gt under Tasks click Elements

2 Select the Element whose debug output you require and click Edit

3 Scroll down to Application Classes gt click the Application class for which you want toenable the debug mode gt click Edit

4 Select Yes from the drop-down Debug Mode list gt SaveBy default BMC Performance Manager Express for EMC Disk Arrays sends its debug output to RSM_HOMERSM(xx)serverrsmlogsen_debuglog

5 Wait for 15 minutes and then disable the debug mode by selecting No

6 Send the debug file to the support team

Pay attention to the file size -the debug output of BMC Performance Manager Express for EMC Disk Arrays could bevery large if enabled for several days

Identifying the Hosts that canAccess a LUNIn most SAN configurations each LUN belongs to a storage group whose host members are the onlyones authorized to access the LUN This is called LUN masking For each LUN the solution displaysits WWN the storage group to which it belongs to as well as the hosts member of this group Inmost cases identifying the storage group of a LUN is sufficient to recognize the server that is usingit

52Identifying LUNs not Owned by their Normal(Default) Storage Processor

BMC Performance Manager Express for EMC Disk Arrays

Version 2001

Identifying LUNs not Owned bytheir Normal (Default) StorageProcessorThe Owning Storage Processor parameter reports the name of the controller that handles IOsfor each LUN If a LUN is not currently handled by its normal (default) storage processors the nameof the default controller will be indicated as SP_B (default SP_A)rdquo

To identify LUNs that are not owned by their normal storage processor you simply need to list the Volume objects where the Owning Storage Processor parameter contains the string Default

Identifying Most Busy LUNs

To identify the LUNs that generate the most traffic on the disk array use the Read Byte Rate andWrite Byte Rate parameters of the LUN class that expose the data throughput for each LUN Usethese parameters to report on the total data traffic (per hour or per day) on each LUN in GB

To make sure that traffic is displayed cumulatively per hour select a time window of at least 12 hours in the graphwindow select at least 7 days to visualize per day cumulative data

1 In the Status tab click the Volume for which you need to check the LUNs activity then expandthe LUNs object to display the ReadWrite Byte Rate parameters

53Identifying Most Busy LUNs

BMC Performance Manager Express for EMC Disk Arrays

Version 2001

Selecting a LUNs ReadW rite Byte Rate Parameter

2 Click the History icon to automatically display a graph that shows the ReadWrite Byte Ratevalues collected for a selected parameter during the previous six hours You can customize thechart and table to show parameter history for different time periods

54Identifying Most Busy LUNs

BMC Performance Manager Express for EMC Disk Arrays

Version 2001

View ing a LUNs ReadW rite Byte Rate as a graph

Identifying a Storage Processor(Controllers) OverloadTo visualize the activity of a controller in an EMC disk array use the Processor Utilizationparameter of the SEN_EMC_CONTROLLER class A warning is issued when the processor utilizationgoes too high which means that the controllers cannot keep up with the load on the disk array It isthen important to identify what is overloading the controllers

The Response Time parameter of the SEN_EMC_CONTROLLER class represents the average time ittook the controller to process the read and write requests of the hosts The higher the ResponseTime goes the slower IOs the servers will get By default the solution triggers a warning when thecontroller takes more than 10 milliseconds on average to complete the IO requests and an alarmwhen the response time reaches 100 milliseconds

Monitoring the Efficiency of theCaching MechanismEach controller in an EMC disk array can be configured to use a specified amount of memory tocache the read andor write operations The solution reports the amount of memory configured byeach controller for the read and write operations

The Write Flush Byte Rate represents the rate in MBsec at which data is committed to the disk(ie physically written) This value is to be compared with the Write Byte Rate of the disk array

55Monitoring the Efficiency of the CachingMechanism

BMC Performance Manager Express for EMC Disk Arrays

Version 2001

Comparing W rite Flush Byte Rate w ith W rite Byte Rate

The Cache Dirty Pages Percentage parameter represents the amount in percentage of the writecache that has been modified by host write operations and not yet flushed to the disks Reaching100 means that write case is too small and cannot handle the flow of write operations

Checking the Cache Dirty Pages Percentage

Reclaiming Space of Unmapped(Unused) LUNsOver time as servers connected to a SAN get decommissioned administrators find an increasingnumber of unmapped LUNs or volumes that are no longer used by any server These LUNs whileunused still occupy disk space in the disk array Being able to identify such unmapped LUNs andreclaim the disk space uselessly consumed by these LUNs will help administrators avoid unnecessaryupgrades and extensions of their disk arrays

56Reporting a Disk Space Consumption

BMC Performance Manager Express for EMC Disk Arrays

Version 2001

Reporting a Disk SpaceConsumptionMaking sure that a disk array has enough remaining disk space available is critical for severalreasons

middot SAN administrators want to make sure to be able to provision disk space for new servers whenrequested as quickly as possible

middot The disk array itself may need additional disk space for specific features to work properly likeautomatic snapshots mirroring etc

middot If thin provisioning is used the remaining disk space becomes dramatically critical since theinability to allocate additional space to a LUN when requested by the subscriber host will lead tocatastrophic data loss and corruption

The disk space used is permanently monitored for each storage pool The Subscribed Capacityparameter of the Pool class represents the amount of disk space that has been made available tothe subscriber hosts or in other words the amount of disk space that is seen by the serversconnected to disk array

The Consumed Capacity parameter of the SEN_EMC_STORAGEPOOLS class represents the actualspace usage in the storage pool For thin pools (when thin provisioning is enabled on the disk array)this value is normally lower than the Subscribed Capacity as it is the main purpose of thinprovisioning For traditional pools the Consumed Capacity parameters has the same value as theSubscribed Capacity parameter as the entirety of the subscribed disk space is fully allocated inthe storage pool

The Consumed Capacity Percentage parameter is the most critical one as a storage pool usagenearing 100 means that SAN administrators will not be able to create new LUNs in the storagepool By default no alarm or warning threshold is set on this parameter as the fullness of a storagepool may be a normal situation However you can set alert thresholds on this parameter as it fitsyour needs

57Reporting a Disk Space Consumption

BMC Performance Manager Express for EMC Disk Arrays

Version 2001

Verifying the Available Disk Space in the Storage Pool of your EMC DiskArrays

1 In the Configure tab select an element group in the tree view (the main ldquoInfrastructurerdquogroup for example)

2 Click on the Reports tab

3 Create a report for the last 24 hours top 50 values of the Array|Storage Pools|Disk Group|Storage Pool|Consumed Capacity Percentage parameter of the EMC Disk Arraysapplication class for the BMC Performance Manager Express for EMC Disk Arrays by SentrySoftware solution

Report ndash Disk Space Consumption

Reporting the Total Traffic on anHourly or Daily BasisBMC Performance Manager Express for EMC Disk Arrays not only monitors the traffic and activity ofthe disk array controllers LUNs and physical disks in MBsec but also in GB per hour or per day Theexact amount of data that was read or written to the disk array LUN or physical disk is calculated foreach hour of the day and each day of the week

Each data rate parameter in MBsec is accompanied by a non-rate one in GB These parameters areldquocumulativerdquo their instantaneous value has no meaning and they need to be visualized in a longperiod of time (instead of Read Byte Rate or Write Byte Rate)

58Reporting the Total Traffic on an Hourly orDaily Basis

BMC Performance Manager Express for EMC Disk Arrays

Setting thresholds

Whenever relevant BMC Performance Manager Express for EMC Disk Arrays automatically setsthresholds for parameters If you prefer a more fault-tolerant monitoring you can modify thethresholds of each parameter through the Configure tab gt Edit Thresholds

It is strongly recommended to wait for all the storage objects to be discovered before setting threshold values to avoidhaving to enter thresholds for each occurrence of the application class

To modify the parameter thresholds of several storage objects of an element

60Setting thresholds

BMC Performance Manager Express for EMC Disk Arrays

Version 2001

1 In the Configure tab click on the Storage (ltplatformgt) or the instance icon gt Edit

Thresholds Properties and Credentials

Any modification to the thresholds or any other properties of elements created using the Element

Profile mode is to be done using the Element Profile route or by clicking Override Profile

2 Uncheck the Warning and Alarm boxes for all the parameters for which you want to disablethe alert conditions

3 Check the Warning and Alarm boxes for all the parameters for which you want to enable thealert conditions You will then have to manually enter the threshold values and check the Activebox In the example below a Warning will be triggered if Status is greater than 1 an alarm willbe triggered when greater than 2

Modifying threshold values

4 Click Save

5 The Success changes have been saved message indicates that the modifications have beenregistered

Alerts are displayed by the parameter whose thresholds are modified

Viewing the Overall Activity of aDisk ArrayIn order to visualize the activity of a disk array use the Read Byte Rate and Write Byte Rate ofthe SEN_EMC_ARRAY class These parameters represent the overall traffic in megabytes per secondfor each monitored array or more precisely each EMC disk array that is exposed through the EMCSMI-S Provider (see the EMC_SMI-S_Provider section of the Installation Guide for more informationabout the EMC SMI-S Provider)

62Viewing the Overall Activity of a Disk Array

BMC Performance Manager Express for EMC Disk Arrays

Version 2001

Viewing a Disk Array Activity

1 Click the Status tab in Portal

2 Click the array icon in the tree view to visualize its current activity

Selecting a Disk Array Parameter

Managing Baselines and KeyPerformance IndicatorsIn order to facilitate the detection of abnormalities on your monitored environment BMCProactiveNet calculates baselines per parameter (metrics or attributes) based on values collectedover a specified period of time to determine a normal operating range When the collected values forthese parameters are out of range an alert is triggered

Some parameters are identified by default as Key Performance Indicators and therefore automaticallyincluded in the base lining calculation

42Managing Baselines and Key PerformanceIndicators

BMC Performance Manager Express for EMC Disk Arrays

Version 2001

Managing baselines

The baseline is the expected normal operating range for a metric or attribute of a monitor

The baseline is calculated by collecting the values for a monitorrsquos attributes and metrics over aspecified time period and establishing a low baseline value (consisting of the 10th percentile of all thevalues for a given time period) and a high baseline value (consisting of the 90th percentile of all thevalues for a given time period) taking a weighted average of these values over time A higher weightis given to the latest data being factored into the baseline average The accuracy of the baselineimproves over time

Requirements for baseline generation

For baselines to be generated for an attribute that abnormality threshold means that the thresholdexists and is not suppressed Additionally if the Key Performance Indicator (KPI) mode is active only those attributes that have anactive abnormality threshold and are also KPI attributes will have baselines generated for them

Absolute thresholds (with outside baseline) or signature thresholds do not satisfy these requirements

Managing Key Performance Indicators

The KPI attribute of a parameter can be activated or deactivated manually through the BMCProactiveNet Administration Console In this PM some parameters or attributes have beendesignated as important indicators of performance (KPIs) We do not recommend that these defaultsettings are modified

However advanced users may activate or deactivate KPIs from the BMC ProactiveNet AdministrationConsole

To add or remove Key Performance Indicator (KPI) attributes for amonitor type

1 In the Administration Console from the menu bar choose Tools gt KPI AdministrationThe KPI Administration dialog box is displayed

2 From the Monitor Type list choose the monitor type for which you want to add or remove KPIattributes A list of attributes for the selected monitor type is displayed

3 In the KPI column for the attributes that you want to add or remove as Key PerformanceIndicators

middot select the KPI check box to add the corresponding attribute as a KPI

middot deselect the KPI check box to remove the corresponding attribute from the KPIs for thatmonitor type

For complete and detailed information on this procedure please refer to the BMC ProactiveNet documentation availablefrom BMC Web site

BMC Performance Manager Express for EMC Disk Arrays

Version 2001

BMC Performance Manager Express for EMC Disk Arrays monitors all of the performance metrics andusage statistics of your EMC disk arrays such as file disk space usage storage controller utilizationIOs on the diskscontrollersvolumes etc It continuously monitors the activity of each array and isalso able to build reports on past utilization statistics

To setup a complete monitoring of the array we strongly recommend you to also use BMCPerformance Manager Express for Hardware that covers all the physical aspect of the EMC diskarrays (status of the disks ports temperature power supplies power consumption etc)

This chapter explains how to use each monitoring tool ie a separate application class within theBMC Performance Manager Express for EMC Disk Arrays by Sentry Software solution

BMC Performance Manager Express for EMC Disk Arrays is a Performance Manager specifically designedfor BMC Portal consequently it uses the same common features and procedures of BMCreg Portal Thisdocument assumes that the user knows how to use the Portal and therefore explains procedures onlyrelated to BMC Performance Manager Express for EMC Disk Arrays and not on how to add ElementsElement Profiles etc Please refer to the BMC Portal documentation for details on how to use the Portal

Checking Available Spare Disks

To avoid any loss of critical data it is essential for a disk array to always maintain a pool of sparedisks that can replace the faulty disk when a disk failure occurs A disk array without any left sparedisk will not be able to keep the level of data safety and performance in case of a disk failure

The Spare Disk Count parameter of the SEN_EMC_ARRAY class reports the number of spare disksavailable for each disk array monitored with the solution By default a warning is triggered when nospare disk is available (Spare Disk Count is set to zero)

Verifying the Number of Available Spare Disks in Your EMC Disk Arrays

49Checking Available Spare Disks

BMC Performance Manager Express for EMC Disk Arrays

Version 2001

1 Select an element group in the tree view (the main Infrastructure group for example)

2 Click the Reports tab Create a report for the last 24 hours bottom 50 values of the Array|Spare Disk Count parameter of the EMC Disk Arrays application class for the BMC PerformanceManager Express for EMC Disk Arrays by Sentry Software solution

Report ndash Available Spare Disks

Detecting OversubscriptionSituations (Thin Provisioning)We call an oversubscription situation when

1 The storage pool is configured for thin provisioning (ldquothin storage poolrdquo)

2 The storage pool is oversubscribed ie the total disk space visible to the hosts (subscribers) isgreater than its actual capacity (this situation is normal for a thin pool since it is its very purpose)

3 The storage pool actual consumed capacity is nearing 100

Such situation is highly critical because the inability to allocate additional space to a LUN whenrequested by the subscriber host will lead to catastrophic data loss and corruption

When the conditions described above are met the solution sets the Oversubscription Situationparameter to 1 automatically raising a warning By default the warning for OversubscriptionSituation is issued when the Consumed Capacity Percentage parameter goes above 100 Thisthreshold can be configured in the input properties of the solution

50Detecting Oversubscription Situations (ThinProvisioning)

BMC Performance Manager Express for EMC Disk Arrays

Version 2001

Configuring Oversubscription Threshold

1 Click the EMC Disk Arrays icon and then the Configure tab

2 Edit the Oversubscription Situation Threshold () property to the appropriate value Whenthe Oversubscription Situation parameter triggers a warning it is highly recommended thatthe SAN administrators add capacity to the storage pool as soon as possible

Diagnosing Slow LUNs

If a system administrator complains that his servers are experiencing slow IOs performance and thatit is caused by the SAN you may want to verify the actual response time of the LUNs the server isrelying on

The Response Time parameter of the SEN_EMC_VOLUME class represents the average time it tookto complete the read and write operations on the LUN during the collection interval Typically theaverage response time is below 10 milliseconds You may also want to compare this value to theresponse time of the other LUNs to see whether one server is really getting worse IO performancethan another

Volume - Response Time Parameter

If the response time is low you will need to check the amount of data that is written and read onthis LUN The bad performance may simply be due to an abnormally large amount of data to processOtherwise the problem is maybe between the disk array and the server in the fiber links

51Enabling the Debug Mode

BMC Performance Manager Express for EMC Disk Arrays

Version 2001

Enabling the Debug Mode

By default BMC Performance Manager Express for EMC Disk Arrays sends only the most criticalinformation warning and error messages to the Application Collection Status parameter Mostoften this information is accurate enough to ensure that BMC Performance Manager Express for EMCDisk Arrays is functioning properly If you encounter an issue and wish to report it to customersupport you will be asked to enable the Debug Mode and provide the debug output to the supportteam

1 In the Configure tab gt under Tasks click Elements

2 Select the Element whose debug output you require and click Edit

3 Scroll down to Application Classes gt click the Application class for which you want toenable the debug mode gt click Edit

4 Select Yes from the drop-down Debug Mode list gt SaveBy default BMC Performance Manager Express for EMC Disk Arrays sends its debug output to RSM_HOMERSM(xx)serverrsmlogsen_debuglog

5 Wait for 15 minutes and then disable the debug mode by selecting No

6 Send the debug file to the support team

Pay attention to the file size -the debug output of BMC Performance Manager Express for EMC Disk Arrays could bevery large if enabled for several days

Identifying the Hosts that canAccess a LUNIn most SAN configurations each LUN belongs to a storage group whose host members are the onlyones authorized to access the LUN This is called LUN masking For each LUN the solution displaysits WWN the storage group to which it belongs to as well as the hosts member of this group Inmost cases identifying the storage group of a LUN is sufficient to recognize the server that is usingit

52Identifying LUNs not Owned by their Normal(Default) Storage Processor

BMC Performance Manager Express for EMC Disk Arrays

Version 2001

Identifying LUNs not Owned bytheir Normal (Default) StorageProcessorThe Owning Storage Processor parameter reports the name of the controller that handles IOsfor each LUN If a LUN is not currently handled by its normal (default) storage processors the nameof the default controller will be indicated as SP_B (default SP_A)rdquo

To identify LUNs that are not owned by their normal storage processor you simply need to list the Volume objects where the Owning Storage Processor parameter contains the string Default

Identifying Most Busy LUNs

To identify the LUNs that generate the most traffic on the disk array use the Read Byte Rate andWrite Byte Rate parameters of the LUN class that expose the data throughput for each LUN Usethese parameters to report on the total data traffic (per hour or per day) on each LUN in GB

To make sure that traffic is displayed cumulatively per hour select a time window of at least 12 hours in the graphwindow select at least 7 days to visualize per day cumulative data

1 In the Status tab click the Volume for which you need to check the LUNs activity then expandthe LUNs object to display the ReadWrite Byte Rate parameters

53Identifying Most Busy LUNs

54Identifying Most Busy LUNs

BMC Performance Manager Express for EMC Disk Arrays

Version 2001

View ing a LUNs ReadW rite Byte Rate as a graph

Identifying a Storage Processor(Controllers) OverloadTo visualize the activity of a controller in an EMC disk array use the Processor Utilizationparameter of the SEN_EMC_CONTROLLER class A warning is issued when the processor utilizationgoes too high which means that the controllers cannot keep up with the load on the disk array It isthen important to identify what is overloading the controllers

The Response Time parameter of the SEN_EMC_CONTROLLER class represents the average time ittook the controller to process the read and write requests of the hosts The higher the ResponseTime goes the slower IOs the servers will get By default the solution triggers a warning when thecontroller takes more than 10 milliseconds on average to complete the IO requests and an alarmwhen the response time reaches 100 milliseconds

Monitoring the Efficiency of theCaching MechanismEach controller in an EMC disk array can be configured to use a specified amount of memory tocache the read andor write operations The solution reports the amount of memory configured byeach controller for the read and write operations

The Write Flush Byte Rate represents the rate in MBsec at which data is committed to the disk(ie physically written) This value is to be compared with the Write Byte Rate of the disk array

55Monitoring the Efficiency of the CachingMechanism

BMC Performance Manager Express for EMC Disk Arrays

Version 2001

Comparing W rite Flush Byte Rate w ith W rite Byte Rate

The Cache Dirty Pages Percentage parameter represents the amount in percentage of the writecache that has been modified by host write operations and not yet flushed to the disks Reaching100 means that write case is too small and cannot handle the flow of write operations

Checking the Cache Dirty Pages Percentage

Reclaiming Space of Unmapped(Unused) LUNsOver time as servers connected to a SAN get decommissioned administrators find an increasingnumber of unmapped LUNs or volumes that are no longer used by any server These LUNs whileunused still occupy disk space in the disk array Being able to identify such unmapped LUNs andreclaim the disk space uselessly consumed by these LUNs will help administrators avoid unnecessaryupgrades and extensions of their disk arrays

56Reporting a Disk Space Consumption

BMC Performance Manager Express for EMC Disk Arrays

Version 2001

Reporting a Disk SpaceConsumptionMaking sure that a disk array has enough remaining disk space available is critical for severalreasons

middot SAN administrators want to make sure to be able to provision disk space for new servers whenrequested as quickly as possible

middot The disk array itself may need additional disk space for specific features to work properly likeautomatic snapshots mirroring etc

middot If thin provisioning is used the remaining disk space becomes dramatically critical since theinability to allocate additional space to a LUN when requested by the subscriber host will lead tocatastrophic data loss and corruption

The disk space used is permanently monitored for each storage pool The Subscribed Capacityparameter of the Pool class represents the amount of disk space that has been made available tothe subscriber hosts or in other words the amount of disk space that is seen by the serversconnected to disk array

The Consumed Capacity parameter of the SEN_EMC_STORAGEPOOLS class represents the actualspace usage in the storage pool For thin pools (when thin provisioning is enabled on the disk array)this value is normally lower than the Subscribed Capacity as it is the main purpose of thinprovisioning For traditional pools the Consumed Capacity parameters has the same value as theSubscribed Capacity parameter as the entirety of the subscribed disk space is fully allocated inthe storage pool

The Consumed Capacity Percentage parameter is the most critical one as a storage pool usagenearing 100 means that SAN administrators will not be able to create new LUNs in the storagepool By default no alarm or warning threshold is set on this parameter as the fullness of a storagepool may be a normal situation However you can set alert thresholds on this parameter as it fitsyour needs

We strongly recommend that you create a specific adapter for each PM you need to integrate into BMCProactiveNet to enable the update of a single PM independently

Once created and imported the Adapter will be displayed in the Devices folder of the BMCProactiveNet Operations Console

Managing Baselines and KeyPerformance IndicatorsIn order to facilitate the detection of abnormalities on your monitored environment BMCProactiveNet calculates baselines per parameter (metrics or attributes) based on values collectedover a specified period of time to determine a normal operating range When the collected values forthese parameters are out of range an alert is triggered

Some parameters are identified by default as Key Performance Indicators and therefore automaticallyincluded in the base lining calculation

42Managing Baselines and Key PerformanceIndicators

BMC Performance Manager Express for EMC Disk Arrays

Version 2001

Managing baselines

The baseline is the expected normal operating range for a metric or attribute of a monitor

The baseline is calculated by collecting the values for a monitorrsquos attributes and metrics over aspecified time period and establishing a low baseline value (consisting of the 10th percentile of all thevalues for a given time period) and a high baseline value (consisting of the 90th percentile of all thevalues for a given time period) taking a weighted average of these values over time A higher weightis given to the latest data being factored into the baseline average The accuracy of the baselineimproves over time

Requirements for baseline generation

For baselines to be generated for an attribute that abnormality threshold means that the thresholdexists and is not suppressed Additionally if the Key Performance Indicator (KPI) mode is active only those attributes that have anactive abnormality threshold and are also KPI attributes will have baselines generated for them

Absolute thresholds (with outside baseline) or signature thresholds do not satisfy these requirements

Managing Key Performance Indicators

The KPI attribute of a parameter can be activated or deactivated manually through the BMCProactiveNet Administration Console In this PM some parameters or attributes have beendesignated as important indicators of performance (KPIs) We do not recommend that these defaultsettings are modified

However advanced users may activate or deactivate KPIs from the BMC ProactiveNet AdministrationConsole

To add or remove Key Performance Indicator (KPI) attributes for amonitor type

1 In the Administration Console from the menu bar choose Tools gt KPI AdministrationThe KPI Administration dialog box is displayed

2 From the Monitor Type list choose the monitor type for which you want to add or remove KPIattributes A list of attributes for the selected monitor type is displayed

3 In the KPI column for the attributes that you want to add or remove as Key PerformanceIndicators

middot select the KPI check box to add the corresponding attribute as a KPI

middot deselect the KPI check box to remove the corresponding attribute from the KPIs for thatmonitor type

For complete and detailed information on this procedure please refer to the BMC ProactiveNet documentation availablefrom BMC Web site

BMC Performance Manager Express for EMC Disk Arrays

Version 2001

BMC Performance Manager Express for EMC Disk Arrays monitors all of the performance metrics andusage statistics of your EMC disk arrays such as file disk space usage storage controller utilizationIOs on the diskscontrollersvolumes etc It continuously monitors the activity of each array and isalso able to build reports on past utilization statistics

To setup a complete monitoring of the array we strongly recommend you to also use BMCPerformance Manager Express for Hardware that covers all the physical aspect of the EMC diskarrays (status of the disks ports temperature power supplies power consumption etc)

This chapter explains how to use each monitoring tool ie a separate application class within theBMC Performance Manager Express for EMC Disk Arrays by Sentry Software solution

BMC Performance Manager Express for EMC Disk Arrays is a Performance Manager specifically designedfor BMC Portal consequently it uses the same common features and procedures of BMCreg Portal Thisdocument assumes that the user knows how to use the Portal and therefore explains procedures onlyrelated to BMC Performance Manager Express for EMC Disk Arrays and not on how to add ElementsElement Profiles etc Please refer to the BMC Portal documentation for details on how to use the Portal

Checking Available Spare Disks

To avoid any loss of critical data it is essential for a disk array to always maintain a pool of sparedisks that can replace the faulty disk when a disk failure occurs A disk array without any left sparedisk will not be able to keep the level of data safety and performance in case of a disk failure

The Spare Disk Count parameter of the SEN_EMC_ARRAY class reports the number of spare disksavailable for each disk array monitored with the solution By default a warning is triggered when nospare disk is available (Spare Disk Count is set to zero)

Verifying the Number of Available Spare Disks in Your EMC Disk Arrays

49Checking Available Spare Disks

2 The storage pool is oversubscribed ie the total disk space visible to the hosts (subscribers) isgreater than its actual capacity (this situation is normal for a thin pool since it is its very purpose)

3 The storage pool actual consumed capacity is nearing 100

Such situation is highly critical because the inability to allocate additional space to a LUN whenrequested by the subscriber host will lead to catastrophic data loss and corruption

When the conditions described above are met the solution sets the Oversubscription Situationparameter to 1 automatically raising a warning By default the warning for OversubscriptionSituation is issued when the Consumed Capacity Percentage parameter goes above 100 Thisthreshold can be configured in the input properties of the solution

50Detecting Oversubscription Situations (ThinProvisioning)

BMC Performance Manager Express for EMC Disk Arrays

Version 2001

Configuring Oversubscription Threshold

1 Click the EMC Disk Arrays icon and then the Configure tab

2 Edit the Oversubscription Situation Threshold () property to the appropriate value Whenthe Oversubscription Situation parameter triggers a warning it is highly recommended thatthe SAN administrators add capacity to the storage pool as soon as possible

Diagnosing Slow LUNs

If a system administrator complains that his servers are experiencing slow IOs performance and thatit is caused by the SAN you may want to verify the actual response time of the LUNs the server isrelying on

The Response Time parameter of the SEN_EMC_VOLUME class represents the average time it tookto complete the read and write operations on the LUN during the collection interval Typically theaverage response time is below 10 milliseconds You may also want to compare this value to theresponse time of the other LUNs to see whether one server is really getting worse IO performancethan another

Volume - Response Time Parameter

If the response time is low you will need to check the amount of data that is written and read onthis LUN The bad performance may simply be due to an abnormally large amount of data to processOtherwise the problem is maybe between the disk array and the server in the fiber links

51Enabling the Debug Mode

BMC Performance Manager Express for EMC Disk Arrays

Version 2001

Enabling the Debug Mode

By default BMC Performance Manager Express for EMC Disk Arrays sends only the most criticalinformation warning and error messages to the Application Collection Status parameter Mostoften this information is accurate enough to ensure that BMC Performance Manager Express for EMCDisk Arrays is functioning properly If you encounter an issue and wish to report it to customersupport you will be asked to enable the Debug Mode and provide the debug output to the supportteam

1 In the Configure tab gt under Tasks click Elements

2 Select the Element whose debug output you require and click Edit

3 Scroll down to Application Classes gt click the Application class for which you want toenable the debug mode gt click Edit

4 Select Yes from the drop-down Debug Mode list gt SaveBy default BMC Performance Manager Express for EMC Disk Arrays sends its debug output to RSM_HOMERSM(xx)serverrsmlogsen_debuglog

5 Wait for 15 minutes and then disable the debug mode by selecting No

6 Send the debug file to the support team

Pay attention to the file size -the debug output of BMC Performance Manager Express for EMC Disk Arrays could bevery large if enabled for several days

Identifying the Hosts that canAccess a LUNIn most SAN configurations each LUN belongs to a storage group whose host members are the onlyones authorized to access the LUN This is called LUN masking For each LUN the solution displaysits WWN the storage group to which it belongs to as well as the hosts member of this group Inmost cases identifying the storage group of a LUN is sufficient to recognize the server that is usingit

52Identifying LUNs not Owned by their Normal(Default) Storage Processor

BMC Performance Manager Express for EMC Disk Arrays

Version 2001

Identifying LUNs not Owned bytheir Normal (Default) StorageProcessorThe Owning Storage Processor parameter reports the name of the controller that handles IOsfor each LUN If a LUN is not currently handled by its normal (default) storage processors the nameof the default controller will be indicated as SP_B (default SP_A)rdquo

To identify LUNs that are not owned by their normal storage processor you simply need to list the Volume objects where the Owning Storage Processor parameter contains the string Default

Identifying Most Busy LUNs

To identify the LUNs that generate the most traffic on the disk array use the Read Byte Rate andWrite Byte Rate parameters of the LUN class that expose the data throughput for each LUN Usethese parameters to report on the total data traffic (per hour or per day) on each LUN in GB

To make sure that traffic is displayed cumulatively per hour select a time window of at least 12 hours in the graphwindow select at least 7 days to visualize per day cumulative data

1 In the Status tab click the Volume for which you need to check the LUNs activity then expandthe LUNs object to display the ReadWrite Byte Rate parameters

53Identifying Most Busy LUNs

Version 2001

View ing a LUNs ReadW rite Byte Rate as a graph

Identifying a Storage Processor(Controllers) OverloadTo visualize the activity of a controller in an EMC disk array use the Processor Utilizationparameter of the SEN_EMC_CONTROLLER class A warning is issued when the processor utilizationgoes too high which means that the controllers cannot keep up with the load on the disk array It isthen important to identify what is overloading the controllers

The Response Time parameter of the SEN_EMC_CONTROLLER class represents the average time ittook the controller to process the read and write requests of the hosts The higher the ResponseTime goes the slower IOs the servers will get By default the solution triggers a warning when thecontroller takes more than 10 milliseconds on average to complete the IO requests and an alarmwhen the response time reaches 100 milliseconds

Monitoring the Efficiency of theCaching MechanismEach controller in an EMC disk array can be configured to use a specified amount of memory tocache the read andor write operations The solution reports the amount of memory configured byeach controller for the read and write operations

The Write Flush Byte Rate represents the rate in MBsec at which data is committed to the disk(ie physically written) This value is to be compared with the Write Byte Rate of the disk array

55Monitoring the Efficiency of the CachingMechanism

BMC Performance Manager Express for EMC Disk Arrays

Version 2001

Comparing W rite Flush Byte Rate w ith W rite Byte Rate

The Cache Dirty Pages Percentage parameter represents the amount in percentage of the writecache that has been modified by host write operations and not yet flushed to the disks Reaching100 means that write case is too small and cannot handle the flow of write operations

Checking the Cache Dirty Pages Percentage

Reclaiming Space of Unmapped(Unused) LUNsOver time as servers connected to a SAN get decommissioned administrators find an increasingnumber of unmapped LUNs or volumes that are no longer used by any server These LUNs whileunused still occupy disk space in the disk array Being able to identify such unmapped LUNs andreclaim the disk space uselessly consumed by these LUNs will help administrators avoid unnecessaryupgrades and extensions of their disk arrays

56Reporting a Disk Space Consumption

BMC Performance Manager Express for EMC Disk Arrays

Version 2001

Reporting a Disk SpaceConsumptionMaking sure that a disk array has enough remaining disk space available is critical for severalreasons

middot SAN administrators want to make sure to be able to provision disk space for new servers whenrequested as quickly as possible

middot The disk array itself may need additional disk space for specific features to work properly likeautomatic snapshots mirroring etc

middot If thin provisioning is used the remaining disk space becomes dramatically critical since theinability to allocate additional space to a LUN when requested by the subscriber host will lead tocatastrophic data loss and corruption

The disk space used is permanently monitored for each storage pool The Subscribed Capacityparameter of the Pool class represents the amount of disk space that has been made available tothe subscriber hosts or in other words the amount of disk space that is seen by the serversconnected to disk array

The Consumed Capacity parameter of the SEN_EMC_STORAGEPOOLS class represents the actualspace usage in the storage pool For thin pools (when thin provisioning is enabled on the disk array)this value is normally lower than the Subscribed Capacity as it is the main purpose of thinprovisioning For traditional pools the Consumed Capacity parameters has the same value as theSubscribed Capacity parameter as the entirety of the subscribed disk space is fully allocated inthe storage pool

The Consumed Capacity Percentage parameter is the most critical one as a storage pool usagenearing 100 means that SAN administrators will not be able to create new LUNs in the storagepool By default no alarm or warning threshold is set on this parameter as the fullness of a storagepool may be a normal situation However you can set alert thresholds on this parameter as it fitsyour needs

57Reporting a Disk Space Consumption

BMC Performance Manager Express for EMC Disk Arrays

Managing Baselines and KeyPerformance IndicatorsIn order to facilitate the detection of abnormalities on your monitored environment BMCProactiveNet calculates baselines per parameter (metrics or attributes) based on values collectedover a specified period of time to determine a normal operating range When the collected values forthese parameters are out of range an alert is triggered

Some parameters are identified by default as Key Performance Indicators and therefore automaticallyincluded in the base lining calculation

42Managing Baselines and Key PerformanceIndicators

BMC Performance Manager Express for EMC Disk Arrays

Version 2001

Managing baselines

The baseline is the expected normal operating range for a metric or attribute of a monitor

The baseline is calculated by collecting the values for a monitorrsquos attributes and metrics over aspecified time period and establishing a low baseline value (consisting of the 10th percentile of all thevalues for a given time period) and a high baseline value (consisting of the 90th percentile of all thevalues for a given time period) taking a weighted average of these values over time A higher weightis given to the latest data being factored into the baseline average The accuracy of the baselineimproves over time

Requirements for baseline generation

For baselines to be generated for an attribute that abnormality threshold means that the thresholdexists and is not suppressed Additionally if the Key Performance Indicator (KPI) mode is active only those attributes that have anactive abnormality threshold and are also KPI attributes will have baselines generated for them

Absolute thresholds (with outside baseline) or signature thresholds do not satisfy these requirements

Managing Key Performance Indicators

The KPI attribute of a parameter can be activated or deactivated manually through the BMCProactiveNet Administration Console In this PM some parameters or attributes have beendesignated as important indicators of performance (KPIs) We do not recommend that these defaultsettings are modified

However advanced users may activate or deactivate KPIs from the BMC ProactiveNet AdministrationConsole

To add or remove Key Performance Indicator (KPI) attributes for amonitor type

1 In the Administration Console from the menu bar choose Tools gt KPI AdministrationThe KPI Administration dialog box is displayed

2 From the Monitor Type list choose the monitor type for which you want to add or remove KPIattributes A list of attributes for the selected monitor type is displayed

3 In the KPI column for the attributes that you want to add or remove as Key PerformanceIndicators

middot select the KPI check box to add the corresponding attribute as a KPI

middot deselect the KPI check box to remove the corresponding attribute from the KPIs for thatmonitor type

For complete and detailed information on this procedure please refer to the BMC ProactiveNet documentation availablefrom BMC Web site

BMC Performance Manager Express for EMC Disk Arrays

Version 2001

BMC Performance Manager Express for EMC Disk Arrays monitors all of the performance metrics andusage statistics of your EMC disk arrays such as file disk space usage storage controller utilizationIOs on the diskscontrollersvolumes etc It continuously monitors the activity of each array and isalso able to build reports on past utilization statistics

To setup a complete monitoring of the array we strongly recommend you to also use BMCPerformance Manager Express for Hardware that covers all the physical aspect of the EMC diskarrays (status of the disks ports temperature power supplies power consumption etc)

This chapter explains how to use each monitoring tool ie a separate application class within theBMC Performance Manager Express for EMC Disk Arrays by Sentry Software solution

BMC Performance Manager Express for EMC Disk Arrays is a Performance Manager specifically designedfor BMC Portal consequently it uses the same common features and procedures of BMCreg Portal Thisdocument assumes that the user knows how to use the Portal and therefore explains procedures onlyrelated to BMC Performance Manager Express for EMC Disk Arrays and not on how to add ElementsElement Profiles etc Please refer to the BMC Portal documentation for details on how to use the Portal

Checking Available Spare Disks

To avoid any loss of critical data it is essential for a disk array to always maintain a pool of sparedisks that can replace the faulty disk when a disk failure occurs A disk array without any left sparedisk will not be able to keep the level of data safety and performance in case of a disk failure

The Spare Disk Count parameter of the SEN_EMC_ARRAY class reports the number of spare disksavailable for each disk array monitored with the solution By default a warning is triggered when nospare disk is available (Spare Disk Count is set to zero)

Verifying the Number of Available Spare Disks in Your EMC Disk Arrays

49Checking Available Spare Disks

BMC Performance Manager Express for EMC Disk Arrays

Version 2001

1 Select an element group in the tree view (the main Infrastructure group for example)

2 Click the Reports tab Create a report for the last 24 hours bottom 50 values of the Array|Spare Disk Count parameter of the EMC Disk Arrays application class for the BMC PerformanceManager Express for EMC Disk Arrays by Sentry Software solution

Report ndash Available Spare Disks

Detecting OversubscriptionSituations (Thin Provisioning)We call an oversubscription situation when

1 The storage pool is configured for thin provisioning (ldquothin storage poolrdquo)

2 The storage pool is oversubscribed ie the total disk space visible to the hosts (subscribers) isgreater than its actual capacity (this situation is normal for a thin pool since it is its very purpose)

3 The storage pool actual consumed capacity is nearing 100

Such situation is highly critical because the inability to allocate additional space to a LUN whenrequested by the subscriber host will lead to catastrophic data loss and corruption

When the conditions described above are met the solution sets the Oversubscription Situationparameter to 1 automatically raising a warning By default the warning for OversubscriptionSituation is issued when the Consumed Capacity Percentage parameter goes above 100 Thisthreshold can be configured in the input properties of the solution

50Detecting Oversubscription Situations (ThinProvisioning)

BMC Performance Manager Express for EMC Disk Arrays

Version 2001

Configuring Oversubscription Threshold

1 Click the EMC Disk Arrays icon and then the Configure tab

2 Edit the Oversubscription Situation Threshold () property to the appropriate value Whenthe Oversubscription Situation parameter triggers a warning it is highly recommended thatthe SAN administrators add capacity to the storage pool as soon as possible

Diagnosing Slow LUNs

If a system administrator complains that his servers are experiencing slow IOs performance and thatit is caused by the SAN you may want to verify the actual response time of the LUNs the server isrelying on

The Response Time parameter of the SEN_EMC_VOLUME class represents the average time it tookto complete the read and write operations on the LUN during the collection interval Typically theaverage response time is below 10 milliseconds You may also want to compare this value to theresponse time of the other LUNs to see whether one server is really getting worse IO performancethan another

Volume - Response Time Parameter

If the response time is low you will need to check the amount of data that is written and read onthis LUN The bad performance may simply be due to an abnormally large amount of data to processOtherwise the problem is maybe between the disk array and the server in the fiber links

51Enabling the Debug Mode

BMC Performance Manager Express for EMC Disk Arrays

Version 2001

Enabling the Debug Mode

By default BMC Performance Manager Express for EMC Disk Arrays sends only the most criticalinformation warning and error messages to the Application Collection Status parameter Mostoften this information is accurate enough to ensure that BMC Performance Manager Express for EMCDisk Arrays is functioning properly If you encounter an issue and wish to report it to customersupport you will be asked to enable the Debug Mode and provide the debug output to the supportteam

1 In the Configure tab gt under Tasks click Elements

2 Select the Element whose debug output you require and click Edit

3 Scroll down to Application Classes gt click the Application class for which you want toenable the debug mode gt click Edit

4 Select Yes from the drop-down Debug Mode list gt SaveBy default BMC Performance Manager Express for EMC Disk Arrays sends its debug output to RSM_HOMERSM(xx)serverrsmlogsen_debuglog

5 Wait for 15 minutes and then disable the debug mode by selecting No

6 Send the debug file to the support team

Pay attention to the file size -the debug output of BMC Performance Manager Express for EMC Disk Arrays could bevery large if enabled for several days

Identifying the Hosts that canAccess a LUNIn most SAN configurations each LUN belongs to a storage group whose host members are the onlyones authorized to access the LUN This is called LUN masking For each LUN the solution displaysits WWN the storage group to which it belongs to as well as the hosts member of this group Inmost cases identifying the storage group of a LUN is sufficient to recognize the server that is usingit

52Identifying LUNs not Owned by their Normal(Default) Storage Processor

BMC Performance Manager Express for EMC Disk Arrays

Version 2001

Identifying LUNs not Owned bytheir Normal (Default) StorageProcessorThe Owning Storage Processor parameter reports the name of the controller that handles IOsfor each LUN If a LUN is not currently handled by its normal (default) storage processors the nameof the default controller will be indicated as SP_B (default SP_A)rdquo

To identify LUNs that are not owned by their normal storage processor you simply need to list the Volume objects where the Owning Storage Processor parameter contains the string Default

Identifying Most Busy LUNs

To identify the LUNs that generate the most traffic on the disk array use the Read Byte Rate andWrite Byte Rate parameters of the LUN class that expose the data throughput for each LUN Usethese parameters to report on the total data traffic (per hour or per day) on each LUN in GB

To make sure that traffic is displayed cumulatively per hour select a time window of at least 12 hours in the graphwindow select at least 7 days to visualize per day cumulative data

1 In the Status tab click the Volume for which you need to check the LUNs activity then expandthe LUNs object to display the ReadWrite Byte Rate parameters

53Identifying Most Busy LUNs

54Identifying Most Busy LUNs

BMC Performance Manager Express for EMC Disk Arrays

Version 2001

View ing a LUNs ReadW rite Byte Rate as a graph

Identifying a Storage Processor(Controllers) OverloadTo visualize the activity of a controller in an EMC disk array use the Processor Utilizationparameter of the SEN_EMC_CONTROLLER class A warning is issued when the processor utilizationgoes too high which means that the controllers cannot keep up with the load on the disk array It isthen important to identify what is overloading the controllers

The Response Time parameter of the SEN_EMC_CONTROLLER class represents the average time ittook the controller to process the read and write requests of the hosts The higher the ResponseTime goes the slower IOs the servers will get By default the solution triggers a warning when thecontroller takes more than 10 milliseconds on average to complete the IO requests and an alarmwhen the response time reaches 100 milliseconds

Monitoring the Efficiency of theCaching MechanismEach controller in an EMC disk array can be configured to use a specified amount of memory tocache the read andor write operations The solution reports the amount of memory configured byeach controller for the read and write operations

The Write Flush Byte Rate represents the rate in MBsec at which data is committed to the disk(ie physically written) This value is to be compared with the Write Byte Rate of the disk array

55Monitoring the Efficiency of the CachingMechanism

BMC Performance Manager Express for EMC Disk Arrays

Version 2001

Comparing W rite Flush Byte Rate w ith W rite Byte Rate

The Cache Dirty Pages Percentage parameter represents the amount in percentage of the writecache that has been modified by host write operations and not yet flushed to the disks Reaching100 means that write case is too small and cannot handle the flow of write operations

Checking the Cache Dirty Pages Percentage

Reclaiming Space of Unmapped(Unused) LUNsOver time as servers connected to a SAN get decommissioned administrators find an increasingnumber of unmapped LUNs or volumes that are no longer used by any server These LUNs whileunused still occupy disk space in the disk array Being able to identify such unmapped LUNs andreclaim the disk space uselessly consumed by these LUNs will help administrators avoid unnecessaryupgrades and extensions of their disk arrays

56Reporting a Disk Space Consumption

BMC Performance Manager Express for EMC Disk Arrays

Version 2001

Reporting a Disk SpaceConsumptionMaking sure that a disk array has enough remaining disk space available is critical for severalreasons

middot SAN administrators want to make sure to be able to provision disk space for new servers whenrequested as quickly as possible

middot The disk array itself may need additional disk space for specific features to work properly likeautomatic snapshots mirroring etc

middot If thin provisioning is used the remaining disk space becomes dramatically critical since theinability to allocate additional space to a LUN when requested by the subscriber host will lead tocatastrophic data loss and corruption

The disk space used is permanently monitored for each storage pool The Subscribed Capacityparameter of the Pool class represents the amount of disk space that has been made available tothe subscriber hosts or in other words the amount of disk space that is seen by the serversconnected to disk array

The Consumed Capacity parameter of the SEN_EMC_STORAGEPOOLS class represents the actualspace usage in the storage pool For thin pools (when thin provisioning is enabled on the disk array)this value is normally lower than the Subscribed Capacity as it is the main purpose of thinprovisioning For traditional pools the Consumed Capacity parameters has the same value as theSubscribed Capacity parameter as the entirety of the subscribed disk space is fully allocated inthe storage pool

The Consumed Capacity Percentage parameter is the most critical one as a storage pool usagenearing 100 means that SAN administrators will not be able to create new LUNs in the storagepool By default no alarm or warning threshold is set on this parameter as the fullness of a storagepool may be a normal situation However you can set alert thresholds on this parameter as it fitsyour needs

57Reporting a Disk Space Consumption

We strongly recommend that you create a specific adapter for each PM you need to integrate into BMCProactiveNet to enable the update of a single PM independently

Once created and imported the Adapter will be displayed in the Devices folder of the BMCProactiveNet Operations Console

Managing Baselines and KeyPerformance IndicatorsIn order to facilitate the detection of abnormalities on your monitored environment BMCProactiveNet calculates baselines per parameter (metrics or attributes) based on values collectedover a specified period of time to determine a normal operating range When the collected values forthese parameters are out of range an alert is triggered

Some parameters are identified by default as Key Performance Indicators and therefore automaticallyincluded in the base lining calculation

42Managing Baselines and Key PerformanceIndicators

BMC Performance Manager Express for EMC Disk Arrays

Version 2001

Managing baselines

The baseline is the expected normal operating range for a metric or attribute of a monitor

The baseline is calculated by collecting the values for a monitorrsquos attributes and metrics over aspecified time period and establishing a low baseline value (consisting of the 10th percentile of all thevalues for a given time period) and a high baseline value (consisting of the 90th percentile of all thevalues for a given time period) taking a weighted average of these values over time A higher weightis given to the latest data being factored into the baseline average The accuracy of the baselineimproves over time

Requirements for baseline generation

For baselines to be generated for an attribute that abnormality threshold means that the thresholdexists and is not suppressed Additionally if the Key Performance Indicator (KPI) mode is active only those attributes that have anactive abnormality threshold and are also KPI attributes will have baselines generated for them

Absolute thresholds (with outside baseline) or signature thresholds do not satisfy these requirements

Managing Key Performance Indicators

The KPI attribute of a parameter can be activated or deactivated manually through the BMCProactiveNet Administration Console In this PM some parameters or attributes have beendesignated as important indicators of performance (KPIs) We do not recommend that these defaultsettings are modified

However advanced users may activate or deactivate KPIs from the BMC ProactiveNet AdministrationConsole

To add or remove Key Performance Indicator (KPI) attributes for amonitor type

1 In the Administration Console from the menu bar choose Tools gt KPI AdministrationThe KPI Administration dialog box is displayed

2 From the Monitor Type list choose the monitor type for which you want to add or remove KPIattributes A list of attributes for the selected monitor type is displayed

3 In the KPI column for the attributes that you want to add or remove as Key PerformanceIndicators

middot select the KPI check box to add the corresponding attribute as a KPI

BMC Performance Manager Express for EMC Disk Arrays

Version 2001

BMC Performance Manager Express for EMC Disk Arrays monitors all of the performance metrics andusage statistics of your EMC disk arrays such as file disk space usage storage controller utilizationIOs on the diskscontrollersvolumes etc It continuously monitors the activity of each array and isalso able to build reports on past utilization statistics

To setup a complete monitoring of the array we strongly recommend you to also use BMCPerformance Manager Express for Hardware that covers all the physical aspect of the EMC diskarrays (status of the disks ports temperature power supplies power consumption etc)

This chapter explains how to use each monitoring tool ie a separate application class within theBMC Performance Manager Express for EMC Disk Arrays by Sentry Software solution

BMC Performance Manager Express for EMC Disk Arrays is a Performance Manager specifically designedfor BMC Portal consequently it uses the same common features and procedures of BMCreg Portal Thisdocument assumes that the user knows how to use the Portal and therefore explains procedures onlyrelated to BMC Performance Manager Express for EMC Disk Arrays and not on how to add ElementsElement Profiles etc Please refer to the BMC Portal documentation for details on how to use the Portal

Checking Available Spare Disks

To avoid any loss of critical data it is essential for a disk array to always maintain a pool of sparedisks that can replace the faulty disk when a disk failure occurs A disk array without any left sparedisk will not be able to keep the level of data safety and performance in case of a disk failure

The Spare Disk Count parameter of the SEN_EMC_ARRAY class reports the number of spare disksavailable for each disk array monitored with the solution By default a warning is triggered when nospare disk is available (Spare Disk Count is set to zero)

Verifying the Number of Available Spare Disks in Your EMC Disk Arrays

49Checking Available Spare Disks

BMC Performance Manager Express for EMC Disk Arrays

Version 2001

1 Select an element group in the tree view (the main Infrastructure group for example)

2 Click the Reports tab Create a report for the last 24 hours bottom 50 values of the Array|Spare Disk Count parameter of the EMC Disk Arrays application class for the BMC PerformanceManager Express for EMC Disk Arrays by Sentry Software solution

Report ndash Available Spare Disks

Detecting OversubscriptionSituations (Thin Provisioning)We call an oversubscription situation when

1 The storage pool is configured for thin provisioning (ldquothin storage poolrdquo)

2 The storage pool is oversubscribed ie the total disk space visible to the hosts (subscribers) isgreater than its actual capacity (this situation is normal for a thin pool since it is its very purpose)

3 The storage pool actual consumed capacity is nearing 100

Such situation is highly critical because the inability to allocate additional space to a LUN whenrequested by the subscriber host will lead to catastrophic data loss and corruption

When the conditions described above are met the solution sets the Oversubscription Situationparameter to 1 automatically raising a warning By default the warning for OversubscriptionSituation is issued when the Consumed Capacity Percentage parameter goes above 100 Thisthreshold can be configured in the input properties of the solution

50Detecting Oversubscription Situations (ThinProvisioning)

BMC Performance Manager Express for EMC Disk Arrays

Version 2001

Configuring Oversubscription Threshold

1 Click the EMC Disk Arrays icon and then the Configure tab

2 Edit the Oversubscription Situation Threshold () property to the appropriate value Whenthe Oversubscription Situation parameter triggers a warning it is highly recommended thatthe SAN administrators add capacity to the storage pool as soon as possible

Diagnosing Slow LUNs

If a system administrator complains that his servers are experiencing slow IOs performance and thatit is caused by the SAN you may want to verify the actual response time of the LUNs the server isrelying on

The Response Time parameter of the SEN_EMC_VOLUME class represents the average time it tookto complete the read and write operations on the LUN during the collection interval Typically theaverage response time is below 10 milliseconds You may also want to compare this value to theresponse time of the other LUNs to see whether one server is really getting worse IO performancethan another

Volume - Response Time Parameter

If the response time is low you will need to check the amount of data that is written and read onthis LUN The bad performance may simply be due to an abnormally large amount of data to processOtherwise the problem is maybe between the disk array and the server in the fiber links

51Enabling the Debug Mode

BMC Performance Manager Express for EMC Disk Arrays

Version 2001

Enabling the Debug Mode

By default BMC Performance Manager Express for EMC Disk Arrays sends only the most criticalinformation warning and error messages to the Application Collection Status parameter Mostoften this information is accurate enough to ensure that BMC Performance Manager Express for EMCDisk Arrays is functioning properly If you encounter an issue and wish to report it to customersupport you will be asked to enable the Debug Mode and provide the debug output to the supportteam

1 In the Configure tab gt under Tasks click Elements

2 Select the Element whose debug output you require and click Edit

3 Scroll down to Application Classes gt click the Application class for which you want toenable the debug mode gt click Edit

4 Select Yes from the drop-down Debug Mode list gt SaveBy default BMC Performance Manager Express for EMC Disk Arrays sends its debug output to RSM_HOMERSM(xx)serverrsmlogsen_debuglog

5 Wait for 15 minutes and then disable the debug mode by selecting No

6 Send the debug file to the support team

Pay attention to the file size -the debug output of BMC Performance Manager Express for EMC Disk Arrays could bevery large if enabled for several days

Identifying the Hosts that canAccess a LUNIn most SAN configurations each LUN belongs to a storage group whose host members are the onlyones authorized to access the LUN This is called LUN masking For each LUN the solution displaysits WWN the storage group to which it belongs to as well as the hosts member of this group Inmost cases identifying the storage group of a LUN is sufficient to recognize the server that is usingit

52Identifying LUNs not Owned by their Normal(Default) Storage Processor

BMC Performance Manager Express for EMC Disk Arrays

Version 2001

Identifying LUNs not Owned bytheir Normal (Default) StorageProcessorThe Owning Storage Processor parameter reports the name of the controller that handles IOsfor each LUN If a LUN is not currently handled by its normal (default) storage processors the nameof the default controller will be indicated as SP_B (default SP_A)rdquo

To identify LUNs that are not owned by their normal storage processor you simply need to list the Volume objects where the Owning Storage Processor parameter contains the string Default

Identifying Most Busy LUNs

To identify the LUNs that generate the most traffic on the disk array use the Read Byte Rate andWrite Byte Rate parameters of the LUN class that expose the data throughput for each LUN Usethese parameters to report on the total data traffic (per hour or per day) on each LUN in GB

To make sure that traffic is displayed cumulatively per hour select a time window of at least 12 hours in the graphwindow select at least 7 days to visualize per day cumulative data

1 In the Status tab click the Volume for which you need to check the LUNs activity then expandthe LUNs object to display the ReadWrite Byte Rate parameters

53Identifying Most Busy LUNs

2 Click the History icon to automatically display a graph that shows the ReadWrite Byte Ratevalues collected for a selected parameter during the previous six hours You can customize thechart and table to show parameter history for different time periods

54Identifying Most Busy LUNs

BMC Performance Manager Express for EMC Disk Arrays

Version 2001

View ing a LUNs ReadW rite Byte Rate as a graph

Identifying a Storage Processor(Controllers) OverloadTo visualize the activity of a controller in an EMC disk array use the Processor Utilizationparameter of the SEN_EMC_CONTROLLER class A warning is issued when the processor utilizationgoes too high which means that the controllers cannot keep up with the load on the disk array It isthen important to identify what is overloading the controllers

The Response Time parameter of the SEN_EMC_CONTROLLER class represents the average time ittook the controller to process the read and write requests of the hosts The higher the ResponseTime goes the slower IOs the servers will get By default the solution triggers a warning when thecontroller takes more than 10 milliseconds on average to complete the IO requests and an alarmwhen the response time reaches 100 milliseconds

Monitoring the Efficiency of theCaching MechanismEach controller in an EMC disk array can be configured to use a specified amount of memory tocache the read andor write operations The solution reports the amount of memory configured byeach controller for the read and write operations

The Write Flush Byte Rate represents the rate in MBsec at which data is committed to the disk(ie physically written) This value is to be compared with the Write Byte Rate of the disk array

55Monitoring the Efficiency of the CachingMechanism

BMC Performance Manager Express for EMC Disk Arrays

Version 2001

Comparing W rite Flush Byte Rate w ith W rite Byte Rate

The Cache Dirty Pages Percentage parameter represents the amount in percentage of the writecache that has been modified by host write operations and not yet flushed to the disks Reaching100 means that write case is too small and cannot handle the flow of write operations

Checking the Cache Dirty Pages Percentage

Reclaiming Space of Unmapped(Unused) LUNsOver time as servers connected to a SAN get decommissioned administrators find an increasingnumber of unmapped LUNs or volumes that are no longer used by any server These LUNs whileunused still occupy disk space in the disk array Being able to identify such unmapped LUNs andreclaim the disk space uselessly consumed by these LUNs will help administrators avoid unnecessaryupgrades and extensions of their disk arrays

56Reporting a Disk Space Consumption

BMC Performance Manager Express for EMC Disk Arrays

Version 2001

Reporting a Disk SpaceConsumptionMaking sure that a disk array has enough remaining disk space available is critical for severalreasons

middot SAN administrators want to make sure to be able to provision disk space for new servers whenrequested as quickly as possible

middot The disk array itself may need additional disk space for specific features to work properly likeautomatic snapshots mirroring etc

middot If thin provisioning is used the remaining disk space becomes dramatically critical since theinability to allocate additional space to a LUN when requested by the subscriber host will lead tocatastrophic data loss and corruption

The disk space used is permanently monitored for each storage pool The Subscribed Capacityparameter of the Pool class represents the amount of disk space that has been made available tothe subscriber hosts or in other words the amount of disk space that is seen by the serversconnected to disk array

The Consumed Capacity parameter of the SEN_EMC_STORAGEPOOLS class represents the actualspace usage in the storage pool For thin pools (when thin provisioning is enabled on the disk array)this value is normally lower than the Subscribed Capacity as it is the main purpose of thinprovisioning For traditional pools the Consumed Capacity parameters has the same value as theSubscribed Capacity parameter as the entirety of the subscribed disk space is fully allocated inthe storage pool

The Consumed Capacity Percentage parameter is the most critical one as a storage pool usagenearing 100 means that SAN administrators will not be able to create new LUNs in the storagepool By default no alarm or warning threshold is set on this parameter as the fullness of a storagepool may be a normal situation However you can set alert thresholds on this parameter as it fitsyour needs

57Reporting a Disk Space Consumption

Managing Baselines and KeyPerformance IndicatorsIn order to facilitate the detection of abnormalities on your monitored environment BMCProactiveNet calculates baselines per parameter (metrics or attributes) based on values collectedover a specified period of time to determine a normal operating range When the collected values forthese parameters are out of range an alert is triggered

Some parameters are identified by default as Key Performance Indicators and therefore automaticallyincluded in the base lining calculation

42Managing Baselines and Key PerformanceIndicators

BMC Performance Manager Express for EMC Disk Arrays

Version 2001

Managing baselines

The baseline is the expected normal operating range for a metric or attribute of a monitor

The baseline is calculated by collecting the values for a monitorrsquos attributes and metrics over aspecified time period and establishing a low baseline value (consisting of the 10th percentile of all thevalues for a given time period) and a high baseline value (consisting of the 90th percentile of all thevalues for a given time period) taking a weighted average of these values over time A higher weightis given to the latest data being factored into the baseline average The accuracy of the baselineimproves over time

Requirements for baseline generation

For baselines to be generated for an attribute that abnormality threshold means that the thresholdexists and is not suppressed Additionally if the Key Performance Indicator (KPI) mode is active only those attributes that have anactive abnormality threshold and are also KPI attributes will have baselines generated for them

Absolute thresholds (with outside baseline) or signature thresholds do not satisfy these requirements

Managing Key Performance Indicators

The KPI attribute of a parameter can be activated or deactivated manually through the BMCProactiveNet Administration Console In this PM some parameters or attributes have beendesignated as important indicators of performance (KPIs) We do not recommend that these defaultsettings are modified

However advanced users may activate or deactivate KPIs from the BMC ProactiveNet AdministrationConsole

To add or remove Key Performance Indicator (KPI) attributes for amonitor type

1 In the Administration Console from the menu bar choose Tools gt KPI AdministrationThe KPI Administration dialog box is displayed

2 From the Monitor Type list choose the monitor type for which you want to add or remove KPIattributes A list of attributes for the selected monitor type is displayed

3 In the KPI column for the attributes that you want to add or remove as Key PerformanceIndicators

middot select the KPI check box to add the corresponding attribute as a KPI

middot deselect the KPI check box to remove the corresponding attribute from the KPIs for thatmonitor type

For complete and detailed information on this procedure please refer to the BMC ProactiveNet documentation availablefrom BMC Web site

BMC Performance Manager Express for EMC Disk Arrays

Version 2001

BMC Performance Manager Express for EMC Disk Arrays monitors all of the performance metrics andusage statistics of your EMC disk arrays such as file disk space usage storage controller utilizationIOs on the diskscontrollersvolumes etc It continuously monitors the activity of each array and isalso able to build reports on past utilization statistics

To setup a complete monitoring of the array we strongly recommend you to also use BMCPerformance Manager Express for Hardware that covers all the physical aspect of the EMC diskarrays (status of the disks ports temperature power supplies power consumption etc)

This chapter explains how to use each monitoring tool ie a separate application class within theBMC Performance Manager Express for EMC Disk Arrays by Sentry Software solution

BMC Performance Manager Express for EMC Disk Arrays is a Performance Manager specifically designedfor BMC Portal consequently it uses the same common features and procedures of BMCreg Portal Thisdocument assumes that the user knows how to use the Portal and therefore explains procedures onlyrelated to BMC Performance Manager Express for EMC Disk Arrays and not on how to add ElementsElement Profiles etc Please refer to the BMC Portal documentation for details on how to use the Portal

Checking Available Spare Disks

To avoid any loss of critical data it is essential for a disk array to always maintain a pool of sparedisks that can replace the faulty disk when a disk failure occurs A disk array without any left sparedisk will not be able to keep the level of data safety and performance in case of a disk failure

The Spare Disk Count parameter of the SEN_EMC_ARRAY class reports the number of spare disksavailable for each disk array monitored with the solution By default a warning is triggered when nospare disk is available (Spare Disk Count is set to zero)

Verifying the Number of Available Spare Disks in Your EMC Disk Arrays

49Checking Available Spare Disks

BMC Performance Manager Express for EMC Disk Arrays

Version 2001

1 Select an element group in the tree view (the main Infrastructure group for example)

2 Click the Reports tab Create a report for the last 24 hours bottom 50 values of the Array|Spare Disk Count parameter of the EMC Disk Arrays application class for the BMC PerformanceManager Express for EMC Disk Arrays by Sentry Software solution

Report ndash Available Spare Disks

Detecting OversubscriptionSituations (Thin Provisioning)We call an oversubscription situation when

1 The storage pool is configured for thin provisioning (ldquothin storage poolrdquo)

2 The storage pool is oversubscribed ie the total disk space visible to the hosts (subscribers) isgreater than its actual capacity (this situation is normal for a thin pool since it is its very purpose)

3 The storage pool actual consumed capacity is nearing 100

Such situation is highly critical because the inability to allocate additional space to a LUN whenrequested by the subscriber host will lead to catastrophic data loss and corruption

When the conditions described above are met the solution sets the Oversubscription Situationparameter to 1 automatically raising a warning By default the warning for OversubscriptionSituation is issued when the Consumed Capacity Percentage parameter goes above 100 Thisthreshold can be configured in the input properties of the solution

50Detecting Oversubscription Situations (ThinProvisioning)

BMC Performance Manager Express for EMC Disk Arrays

Version 2001

Configuring Oversubscription Threshold

1 Click the EMC Disk Arrays icon and then the Configure tab

2 Edit the Oversubscription Situation Threshold () property to the appropriate value Whenthe Oversubscription Situation parameter triggers a warning it is highly recommended thatthe SAN administrators add capacity to the storage pool as soon as possible

Diagnosing Slow LUNs

If a system administrator complains that his servers are experiencing slow IOs performance and thatit is caused by the SAN you may want to verify the actual response time of the LUNs the server isrelying on

The Response Time parameter of the SEN_EMC_VOLUME class represents the average time it tookto complete the read and write operations on the LUN during the collection interval Typically theaverage response time is below 10 milliseconds You may also want to compare this value to theresponse time of the other LUNs to see whether one server is really getting worse IO performancethan another

Volume - Response Time Parameter

If the response time is low you will need to check the amount of data that is written and read onthis LUN The bad performance may simply be due to an abnormally large amount of data to processOtherwise the problem is maybe between the disk array and the server in the fiber links

51Enabling the Debug Mode

BMC Performance Manager Express for EMC Disk Arrays

Version 2001

Enabling the Debug Mode

By default BMC Performance Manager Express for EMC Disk Arrays sends only the most criticalinformation warning and error messages to the Application Collection Status parameter Mostoften this information is accurate enough to ensure that BMC Performance Manager Express for EMCDisk Arrays is functioning properly If you encounter an issue and wish to report it to customersupport you will be asked to enable the Debug Mode and provide the debug output to the supportteam

1 In the Configure tab gt under Tasks click Elements

2 Select the Element whose debug output you require and click Edit

3 Scroll down to Application Classes gt click the Application class for which you want toenable the debug mode gt click Edit

4 Select Yes from the drop-down Debug Mode list gt SaveBy default BMC Performance Manager Express for EMC Disk Arrays sends its debug output to RSM_HOMERSM(xx)serverrsmlogsen_debuglog

5 Wait for 15 minutes and then disable the debug mode by selecting No

6 Send the debug file to the support team

Pay attention to the file size -the debug output of BMC Performance Manager Express for EMC Disk Arrays could bevery large if enabled for several days

Identifying the Hosts that canAccess a LUNIn most SAN configurations each LUN belongs to a storage group whose host members are the onlyones authorized to access the LUN This is called LUN masking For each LUN the solution displaysits WWN the storage group to which it belongs to as well as the hosts member of this group Inmost cases identifying the storage group of a LUN is sufficient to recognize the server that is usingit

52Identifying LUNs not Owned by their Normal(Default) Storage Processor

BMC Performance Manager Express for EMC Disk Arrays

Version 2001

Identifying LUNs not Owned bytheir Normal (Default) StorageProcessorThe Owning Storage Processor parameter reports the name of the controller that handles IOsfor each LUN If a LUN is not currently handled by its normal (default) storage processors the nameof the default controller will be indicated as SP_B (default SP_A)rdquo

To identify LUNs that are not owned by their normal storage processor you simply need to list the Volume objects where the Owning Storage Processor parameter contains the string Default

Identifying Most Busy LUNs

To identify the LUNs that generate the most traffic on the disk array use the Read Byte Rate andWrite Byte Rate parameters of the LUN class that expose the data throughput for each LUN Usethese parameters to report on the total data traffic (per hour or per day) on each LUN in GB

To make sure that traffic is displayed cumulatively per hour select a time window of at least 12 hours in the graphwindow select at least 7 days to visualize per day cumulative data

1 In the Status tab click the Volume for which you need to check the LUNs activity then expandthe LUNs object to display the ReadWrite Byte Rate parameters

53Identifying Most Busy LUNs

2 Click the History icon to automatically display a graph that shows the ReadWrite Byte Ratevalues collected for a selected parameter during the previous six hours You can customize thechart and table to show parameter history for different time periods

54Identifying Most Busy LUNs

BMC Performance Manager Express for EMC Disk Arrays

Version 2001

View ing a LUNs ReadW rite Byte Rate as a graph

Identifying a Storage Processor(Controllers) OverloadTo visualize the activity of a controller in an EMC disk array use the Processor Utilizationparameter of the SEN_EMC_CONTROLLER class A warning is issued when the processor utilizationgoes too high which means that the controllers cannot keep up with the load on the disk array It isthen important to identify what is overloading the controllers

The Response Time parameter of the SEN_EMC_CONTROLLER class represents the average time ittook the controller to process the read and write requests of the hosts The higher the ResponseTime goes the slower IOs the servers will get By default the solution triggers a warning when thecontroller takes more than 10 milliseconds on average to complete the IO requests and an alarmwhen the response time reaches 100 milliseconds

Monitoring the Efficiency of theCaching MechanismEach controller in an EMC disk array can be configured to use a specified amount of memory tocache the read andor write operations The solution reports the amount of memory configured byeach controller for the read and write operations

The Write Flush Byte Rate represents the rate in MBsec at which data is committed to the disk(ie physically written) This value is to be compared with the Write Byte Rate of the disk array

55Monitoring the Efficiency of the CachingMechanism

BMC Performance Manager Express for EMC Disk Arrays

Version 2001

Comparing W rite Flush Byte Rate w ith W rite Byte Rate

The Cache Dirty Pages Percentage parameter represents the amount in percentage of the writecache that has been modified by host write operations and not yet flushed to the disks Reaching100 means that write case is too small and cannot handle the flow of write operations

Checking the Cache Dirty Pages Percentage

Reclaiming Space of Unmapped(Unused) LUNsOver time as servers connected to a SAN get decommissioned administrators find an increasingnumber of unmapped LUNs or volumes that are no longer used by any server These LUNs whileunused still occupy disk space in the disk array Being able to identify such unmapped LUNs andreclaim the disk space uselessly consumed by these LUNs will help administrators avoid unnecessaryupgrades and extensions of their disk arrays

56Reporting a Disk Space Consumption

BMC Performance Manager Express for EMC Disk Arrays

Version 2001

Reporting a Disk SpaceConsumptionMaking sure that a disk array has enough remaining disk space available is critical for severalreasons

middot SAN administrators want to make sure to be able to provision disk space for new servers whenrequested as quickly as possible

middot The disk array itself may need additional disk space for specific features to work properly likeautomatic snapshots mirroring etc

middot If thin provisioning is used the remaining disk space becomes dramatically critical since theinability to allocate additional space to a LUN when requested by the subscriber host will lead tocatastrophic data loss and corruption

The disk space used is permanently monitored for each storage pool The Subscribed Capacityparameter of the Pool class represents the amount of disk space that has been made available tothe subscriber hosts or in other words the amount of disk space that is seen by the serversconnected to disk array

The Consumed Capacity parameter of the SEN_EMC_STORAGEPOOLS class represents the actualspace usage in the storage pool For thin pools (when thin provisioning is enabled on the disk array)this value is normally lower than the Subscribed Capacity as it is the main purpose of thinprovisioning For traditional pools the Consumed Capacity parameters has the same value as theSubscribed Capacity parameter as the entirety of the subscribed disk space is fully allocated inthe storage pool

The Consumed Capacity Percentage parameter is the most critical one as a storage pool usagenearing 100 means that SAN administrators will not be able to create new LUNs in the storagepool By default no alarm or warning threshold is set on this parameter as the fullness of a storagepool may be a normal situation However you can set alert thresholds on this parameter as it fitsyour needs

57Reporting a Disk Space Consumption

BMC Performance Manager Express for EMC Disk Arrays

Version 2001

Verifying the Available Disk Space in the Storage Pool of your EMC DiskArrays

1 In the Configure tab select an element group in the tree view (the main ldquoInfrastructurerdquogroup for example)

3 Create a report for the last 24 hours top 50 values of the Array|Storage Pools|Disk Group|Storage Pool|Consumed Capacity Percentage parameter of the EMC Disk Arraysapplication class for the BMC Performance Manager Express for EMC Disk Arrays by SentrySoftware solution

Report ndash Disk Space Consumption

Reporting the Total Traffic on anHourly or Daily BasisBMC Performance Manager Express for EMC Disk Arrays not only monitors the traffic and activity ofthe disk array controllers LUNs and physical disks in MBsec but also in GB per hour or per day Theexact amount of data that was read or written to the disk array LUN or physical disk is calculated foreach hour of the day and each day of the week

Each data rate parameter in MBsec is accompanied by a non-rate one in GB These parameters areldquocumulativerdquo their instantaneous value has no meaning and they need to be visualized in a longperiod of time (instead of Read Byte Rate or Write Byte Rate)

Setting thresholds

Whenever relevant BMC Performance Manager Express for EMC Disk Arrays automatically setsthresholds for parameters If you prefer a more fault-tolerant monitoring you can modify thethresholds of each parameter through the Configure tab gt Edit Thresholds

It is strongly recommended to wait for all the storage objects to be discovered before setting threshold values to avoidhaving to enter thresholds for each occurrence of the application class

To modify the parameter thresholds of several storage objects of an element

60Setting thresholds

BMC Performance Manager Express for EMC Disk Arrays

Version 2001

1 In the Configure tab click on the Storage (ltplatformgt) or the instance icon gt Edit

Thresholds Properties and Credentials

Any modification to the thresholds or any other properties of elements created using the Element

Profile mode is to be done using the Element Profile route or by clicking Override Profile

2 Uncheck the Warning and Alarm boxes for all the parameters for which you want to disablethe alert conditions

Managing Baselines and KeyPerformance IndicatorsIn order to facilitate the detection of abnormalities on your monitored environment BMCProactiveNet calculates baselines per parameter (metrics or attributes) based on values collectedover a specified period of time to determine a normal operating range When the collected values forthese parameters are out of range an alert is triggered

Some parameters are identified by default as Key Performance Indicators and therefore automaticallyincluded in the base lining calculation

42Managing Baselines and Key PerformanceIndicators

BMC Performance Manager Express for EMC Disk Arrays

Version 2001

Managing baselines

The baseline is the expected normal operating range for a metric or attribute of a monitor

The baseline is calculated by collecting the values for a monitorrsquos attributes and metrics over aspecified time period and establishing a low baseline value (consisting of the 10th percentile of all thevalues for a given time period) and a high baseline value (consisting of the 90th percentile of all thevalues for a given time period) taking a weighted average of these values over time A higher weightis given to the latest data being factored into the baseline average The accuracy of the baselineimproves over time

Requirements for baseline generation

For baselines to be generated for an attribute that abnormality threshold means that the thresholdexists and is not suppressed Additionally if the Key Performance Indicator (KPI) mode is active only those attributes that have anactive abnormality threshold and are also KPI attributes will have baselines generated for them

Absolute thresholds (with outside baseline) or signature thresholds do not satisfy these requirements

Managing Key Performance Indicators

The KPI attribute of a parameter can be activated or deactivated manually through the BMCProactiveNet Administration Console In this PM some parameters or attributes have beendesignated as important indicators of performance (KPIs) We do not recommend that these defaultsettings are modified

However advanced users may activate or deactivate KPIs from the BMC ProactiveNet AdministrationConsole

To add or remove Key Performance Indicator (KPI) attributes for amonitor type

1 In the Administration Console from the menu bar choose Tools gt KPI AdministrationThe KPI Administration dialog box is displayed

2 From the Monitor Type list choose the monitor type for which you want to add or remove KPIattributes A list of attributes for the selected monitor type is displayed

3 In the KPI column for the attributes that you want to add or remove as Key PerformanceIndicators

middot select the KPI check box to add the corresponding attribute as a KPI

middot deselect the KPI check box to remove the corresponding attribute from the KPIs for thatmonitor type

For complete and detailed information on this procedure please refer to the BMC ProactiveNet documentation availablefrom BMC Web site

BMC Performance Manager Express for EMC Disk Arrays monitors all of the performance metrics andusage statistics of your EMC disk arrays such as file disk space usage storage controller utilizationIOs on the diskscontrollersvolumes etc It continuously monitors the activity of each array and isalso able to build reports on past utilization statistics

To setup a complete monitoring of the array we strongly recommend you to also use BMCPerformance Manager Express for Hardware that covers all the physical aspect of the EMC diskarrays (status of the disks ports temperature power supplies power consumption etc)

This chapter explains how to use each monitoring tool ie a separate application class within theBMC Performance Manager Express for EMC Disk Arrays by Sentry Software solution

BMC Performance Manager Express for EMC Disk Arrays is a Performance Manager specifically designedfor BMC Portal consequently it uses the same common features and procedures of BMCreg Portal Thisdocument assumes that the user knows how to use the Portal and therefore explains procedures onlyrelated to BMC Performance Manager Express for EMC Disk Arrays and not on how to add ElementsElement Profiles etc Please refer to the BMC Portal documentation for details on how to use the Portal

Checking Available Spare Disks

To avoid any loss of critical data it is essential for a disk array to always maintain a pool of sparedisks that can replace the faulty disk when a disk failure occurs A disk array without any left sparedisk will not be able to keep the level of data safety and performance in case of a disk failure

The Spare Disk Count parameter of the SEN_EMC_ARRAY class reports the number of spare disksavailable for each disk array monitored with the solution By default a warning is triggered when nospare disk is available (Spare Disk Count is set to zero)

Verifying the Number of Available Spare Disks in Your EMC Disk Arrays

49Checking Available Spare Disks

BMC Performance Manager Express for EMC Disk Arrays

Version 2001

1 Select an element group in the tree view (the main Infrastructure group for example)

2 Click the Reports tab Create a report for the last 24 hours bottom 50 values of the Array|Spare Disk Count parameter of the EMC Disk Arrays application class for the BMC PerformanceManager Express for EMC Disk Arrays by Sentry Software solution

Detecting OversubscriptionSituations (Thin Provisioning)We call an oversubscription situation when

1 The storage pool is configured for thin provisioning (ldquothin storage poolrdquo)

2 The storage pool is oversubscribed ie the total disk space visible to the hosts (subscribers) isgreater than its actual capacity (this situation is normal for a thin pool since it is its very purpose)

3 The storage pool actual consumed capacity is nearing 100

Such situation is highly critical because the inability to allocate additional space to a LUN whenrequested by the subscriber host will lead to catastrophic data loss and corruption

When the conditions described above are met the solution sets the Oversubscription Situationparameter to 1 automatically raising a warning By default the warning for OversubscriptionSituation is issued when the Consumed Capacity Percentage parameter goes above 100 Thisthreshold can be configured in the input properties of the solution

50Detecting Oversubscription Situations (ThinProvisioning)

BMC Performance Manager Express for EMC Disk Arrays

Version 2001

Configuring Oversubscription Threshold

1 Click the EMC Disk Arrays icon and then the Configure tab

2 Edit the Oversubscription Situation Threshold () property to the appropriate value Whenthe Oversubscription Situation parameter triggers a warning it is highly recommended thatthe SAN administrators add capacity to the storage pool as soon as possible

Diagnosing Slow LUNs

If a system administrator complains that his servers are experiencing slow IOs performance and thatit is caused by the SAN you may want to verify the actual response time of the LUNs the server isrelying on

The Response Time parameter of the SEN_EMC_VOLUME class represents the average time it tookto complete the read and write operations on the LUN during the collection interval Typically theaverage response time is below 10 milliseconds You may also want to compare this value to theresponse time of the other LUNs to see whether one server is really getting worse IO performancethan another

Volume - Response Time Parameter

If the response time is low you will need to check the amount of data that is written and read onthis LUN The bad performance may simply be due to an abnormally large amount of data to processOtherwise the problem is maybe between the disk array and the server in the fiber links

51Enabling the Debug Mode

BMC Performance Manager Express for EMC Disk Arrays

Version 2001

Enabling the Debug Mode

By default BMC Performance Manager Express for EMC Disk Arrays sends only the most criticalinformation warning and error messages to the Application Collection Status parameter Mostoften this information is accurate enough to ensure that BMC Performance Manager Express for EMCDisk Arrays is functioning properly If you encounter an issue and wish to report it to customersupport you will be asked to enable the Debug Mode and provide the debug output to the supportteam

1 In the Configure tab gt under Tasks click Elements

2 Select the Element whose debug output you require and click Edit

3 Scroll down to Application Classes gt click the Application class for which you want toenable the debug mode gt click Edit

4 Select Yes from the drop-down Debug Mode list gt SaveBy default BMC Performance Manager Express for EMC Disk Arrays sends its debug output to RSM_HOMERSM(xx)serverrsmlogsen_debuglog

5 Wait for 15 minutes and then disable the debug mode by selecting No

6 Send the debug file to the support team

Pay attention to the file size -the debug output of BMC Performance Manager Express for EMC Disk Arrays could bevery large if enabled for several days

Identifying the Hosts that canAccess a LUNIn most SAN configurations each LUN belongs to a storage group whose host members are the onlyones authorized to access the LUN This is called LUN masking For each LUN the solution displaysits WWN the storage group to which it belongs to as well as the hosts member of this group Inmost cases identifying the storage group of a LUN is sufficient to recognize the server that is usingit

52Identifying LUNs not Owned by their Normal(Default) Storage Processor

BMC Performance Manager Express for EMC Disk Arrays

Version 2001

Identifying LUNs not Owned bytheir Normal (Default) StorageProcessorThe Owning Storage Processor parameter reports the name of the controller that handles IOsfor each LUN If a LUN is not currently handled by its normal (default) storage processors the nameof the default controller will be indicated as SP_B (default SP_A)rdquo

To identify LUNs that are not owned by their normal storage processor you simply need to list the Volume objects where the Owning Storage Processor parameter contains the string Default

Identifying Most Busy LUNs

To identify the LUNs that generate the most traffic on the disk array use the Read Byte Rate andWrite Byte Rate parameters of the LUN class that expose the data throughput for each LUN Usethese parameters to report on the total data traffic (per hour or per day) on each LUN in GB

To make sure that traffic is displayed cumulatively per hour select a time window of at least 12 hours in the graphwindow select at least 7 days to visualize per day cumulative data

1 In the Status tab click the Volume for which you need to check the LUNs activity then expandthe LUNs object to display the ReadWrite Byte Rate parameters

Version 2001

View ing a LUNs ReadW rite Byte Rate as a graph

Identifying a Storage Processor(Controllers) OverloadTo visualize the activity of a controller in an EMC disk array use the Processor Utilizationparameter of the SEN_EMC_CONTROLLER class A warning is issued when the processor utilizationgoes too high which means that the controllers cannot keep up with the load on the disk array It isthen important to identify what is overloading the controllers

The Response Time parameter of the SEN_EMC_CONTROLLER class represents the average time ittook the controller to process the read and write requests of the hosts The higher the ResponseTime goes the slower IOs the servers will get By default the solution triggers a warning when thecontroller takes more than 10 milliseconds on average to complete the IO requests and an alarmwhen the response time reaches 100 milliseconds

Monitoring the Efficiency of theCaching MechanismEach controller in an EMC disk array can be configured to use a specified amount of memory tocache the read andor write operations The solution reports the amount of memory configured byeach controller for the read and write operations

The Write Flush Byte Rate represents the rate in MBsec at which data is committed to the disk(ie physically written) This value is to be compared with the Write Byte Rate of the disk array

55Monitoring the Efficiency of the CachingMechanism

BMC Performance Manager Express for EMC Disk Arrays

Version 2001

Comparing W rite Flush Byte Rate w ith W rite Byte Rate

The Cache Dirty Pages Percentage parameter represents the amount in percentage of the writecache that has been modified by host write operations and not yet flushed to the disks Reaching100 means that write case is too small and cannot handle the flow of write operations

Checking the Cache Dirty Pages Percentage

Reclaiming Space of Unmapped(Unused) LUNsOver time as servers connected to a SAN get decommissioned administrators find an increasingnumber of unmapped LUNs or volumes that are no longer used by any server These LUNs whileunused still occupy disk space in the disk array Being able to identify such unmapped LUNs andreclaim the disk space uselessly consumed by these LUNs will help administrators avoid unnecessaryupgrades and extensions of their disk arrays

56Reporting a Disk Space Consumption

BMC Performance Manager Express for EMC Disk Arrays

Version 2001

Reporting a Disk SpaceConsumptionMaking sure that a disk array has enough remaining disk space available is critical for severalreasons

middot SAN administrators want to make sure to be able to provision disk space for new servers whenrequested as quickly as possible

middot The disk array itself may need additional disk space for specific features to work properly likeautomatic snapshots mirroring etc

middot If thin provisioning is used the remaining disk space becomes dramatically critical since theinability to allocate additional space to a LUN when requested by the subscriber host will lead tocatastrophic data loss and corruption

The disk space used is permanently monitored for each storage pool The Subscribed Capacityparameter of the Pool class represents the amount of disk space that has been made available tothe subscriber hosts or in other words the amount of disk space that is seen by the serversconnected to disk array

The Consumed Capacity parameter of the SEN_EMC_STORAGEPOOLS class represents the actualspace usage in the storage pool For thin pools (when thin provisioning is enabled on the disk array)this value is normally lower than the Subscribed Capacity as it is the main purpose of thinprovisioning For traditional pools the Consumed Capacity parameters has the same value as theSubscribed Capacity parameter as the entirety of the subscribed disk space is fully allocated inthe storage pool

The Consumed Capacity Percentage parameter is the most critical one as a storage pool usagenearing 100 means that SAN administrators will not be able to create new LUNs in the storagepool By default no alarm or warning threshold is set on this parameter as the fullness of a storagepool may be a normal situation However you can set alert thresholds on this parameter as it fitsyour needs

Managing Baselines and KeyPerformance IndicatorsIn order to facilitate the detection of abnormalities on your monitored environment BMCProactiveNet calculates baselines per parameter (metrics or attributes) based on values collectedover a specified period of time to determine a normal operating range When the collected values forthese parameters are out of range an alert is triggered

Some parameters are identified by default as Key Performance Indicators and therefore automaticallyincluded in the base lining calculation

42Managing Baselines and Key PerformanceIndicators

BMC Performance Manager Express for EMC Disk Arrays

Version 2001

Managing baselines

The baseline is the expected normal operating range for a metric or attribute of a monitor

The baseline is calculated by collecting the values for a monitorrsquos attributes and metrics over aspecified time period and establishing a low baseline value (consisting of the 10th percentile of all thevalues for a given time period) and a high baseline value (consisting of the 90th percentile of all thevalues for a given time period) taking a weighted average of these values over time A higher weightis given to the latest data being factored into the baseline average The accuracy of the baselineimproves over time

Requirements for baseline generation

For baselines to be generated for an attribute that abnormality threshold means that the thresholdexists and is not suppressed Additionally if the Key Performance Indicator (KPI) mode is active only those attributes that have anactive abnormality threshold and are also KPI attributes will have baselines generated for them

Absolute thresholds (with outside baseline) or signature thresholds do not satisfy these requirements

Managing Key Performance Indicators

The KPI attribute of a parameter can be activated or deactivated manually through the BMCProactiveNet Administration Console In this PM some parameters or attributes have beendesignated as important indicators of performance (KPIs) We do not recommend that these defaultsettings are modified

However advanced users may activate or deactivate KPIs from the BMC ProactiveNet AdministrationConsole

To add or remove Key Performance Indicator (KPI) attributes for amonitor type

1 In the Administration Console from the menu bar choose Tools gt KPI AdministrationThe KPI Administration dialog box is displayed

2 From the Monitor Type list choose the monitor type for which you want to add or remove KPIattributes A list of attributes for the selected monitor type is displayed

3 In the KPI column for the attributes that you want to add or remove as Key PerformanceIndicators

middot select the KPI check box to add the corresponding attribute as a KPI

middot deselect the KPI check box to remove the corresponding attribute from the KPIs for thatmonitor type

For complete and detailed information on this procedure please refer to the BMC ProactiveNet documentation availablefrom BMC Web site

BMC Performance Manager Express for EMC Disk Arrays

Version 2001

BMC Performance Manager Express for EMC Disk Arrays monitors all of the performance metrics andusage statistics of your EMC disk arrays such as file disk space usage storage controller utilizationIOs on the diskscontrollersvolumes etc It continuously monitors the activity of each array and isalso able to build reports on past utilization statistics

To setup a complete monitoring of the array we strongly recommend you to also use BMCPerformance Manager Express for Hardware that covers all the physical aspect of the EMC diskarrays (status of the disks ports temperature power supplies power consumption etc)

This chapter explains how to use each monitoring tool ie a separate application class within theBMC Performance Manager Express for EMC Disk Arrays by Sentry Software solution

BMC Performance Manager Express for EMC Disk Arrays is a Performance Manager specifically designedfor BMC Portal consequently it uses the same common features and procedures of BMCreg Portal Thisdocument assumes that the user knows how to use the Portal and therefore explains procedures onlyrelated to BMC Performance Manager Express for EMC Disk Arrays and not on how to add ElementsElement Profiles etc Please refer to the BMC Portal documentation for details on how to use the Portal

Checking Available Spare Disks

To avoid any loss of critical data it is essential for a disk array to always maintain a pool of sparedisks that can replace the faulty disk when a disk failure occurs A disk array without any left sparedisk will not be able to keep the level of data safety and performance in case of a disk failure

The Spare Disk Count parameter of the SEN_EMC_ARRAY class reports the number of spare disksavailable for each disk array monitored with the solution By default a warning is triggered when nospare disk is available (Spare Disk Count is set to zero)

Verifying the Number of Available Spare Disks in Your EMC Disk Arrays

49Checking Available Spare Disks

BMC Performance Manager Express for EMC Disk Arrays

Version 2001

1 Select an element group in the tree view (the main Infrastructure group for example)

2 Click the Reports tab Create a report for the last 24 hours bottom 50 values of the Array|Spare Disk Count parameter of the EMC Disk Arrays application class for the BMC PerformanceManager Express for EMC Disk Arrays by Sentry Software solution

Report ndash Available Spare Disks

Detecting OversubscriptionSituations (Thin Provisioning)We call an oversubscription situation when

1 The storage pool is configured for thin provisioning (ldquothin storage poolrdquo)

2 The storage pool is oversubscribed ie the total disk space visible to the hosts (subscribers) isgreater than its actual capacity (this situation is normal for a thin pool since it is its very purpose)

3 The storage pool actual consumed capacity is nearing 100

Such situation is highly critical because the inability to allocate additional space to a LUN whenrequested by the subscriber host will lead to catastrophic data loss and corruption

When the conditions described above are met the solution sets the Oversubscription Situationparameter to 1 automatically raising a warning By default the warning for OversubscriptionSituation is issued when the Consumed Capacity Percentage parameter goes above 100 Thisthreshold can be configured in the input properties of the solution

50Detecting Oversubscription Situations (ThinProvisioning)

BMC Performance Manager Express for EMC Disk Arrays

Version 2001

Configuring Oversubscription Threshold

1 Click the EMC Disk Arrays icon and then the Configure tab

2 Edit the Oversubscription Situation Threshold () property to the appropriate value Whenthe Oversubscription Situation parameter triggers a warning it is highly recommended thatthe SAN administrators add capacity to the storage pool as soon as possible

Diagnosing Slow LUNs

If a system administrator complains that his servers are experiencing slow IOs performance and thatit is caused by the SAN you may want to verify the actual response time of the LUNs the server isrelying on

The Response Time parameter of the SEN_EMC_VOLUME class represents the average time it tookto complete the read and write operations on the LUN during the collection interval Typically theaverage response time is below 10 milliseconds You may also want to compare this value to theresponse time of the other LUNs to see whether one server is really getting worse IO performancethan another

Volume - Response Time Parameter

If the response time is low you will need to check the amount of data that is written and read onthis LUN The bad performance may simply be due to an abnormally large amount of data to processOtherwise the problem is maybe between the disk array and the server in the fiber links

51Enabling the Debug Mode

BMC Performance Manager Express for EMC Disk Arrays

Version 2001

Enabling the Debug Mode

By default BMC Performance Manager Express for EMC Disk Arrays sends only the most criticalinformation warning and error messages to the Application Collection Status parameter Mostoften this information is accurate enough to ensure that BMC Performance Manager Express for EMCDisk Arrays is functioning properly If you encounter an issue and wish to report it to customersupport you will be asked to enable the Debug Mode and provide the debug output to the supportteam

1 In the Configure tab gt under Tasks click Elements

2 Select the Element whose debug output you require and click Edit

3 Scroll down to Application Classes gt click the Application class for which you want toenable the debug mode gt click Edit

4 Select Yes from the drop-down Debug Mode list gt SaveBy default BMC Performance Manager Express for EMC Disk Arrays sends its debug output to RSM_HOMERSM(xx)serverrsmlogsen_debuglog

5 Wait for 15 minutes and then disable the debug mode by selecting No

6 Send the debug file to the support team

Pay attention to the file size -the debug output of BMC Performance Manager Express for EMC Disk Arrays could bevery large if enabled for several days

Identifying the Hosts that canAccess a LUNIn most SAN configurations each LUN belongs to a storage group whose host members are the onlyones authorized to access the LUN This is called LUN masking For each LUN the solution displaysits WWN the storage group to which it belongs to as well as the hosts member of this group Inmost cases identifying the storage group of a LUN is sufficient to recognize the server that is usingit

52Identifying LUNs not Owned by their Normal(Default) Storage Processor

BMC Performance Manager Express for EMC Disk Arrays

Version 2001

Identifying LUNs not Owned bytheir Normal (Default) StorageProcessorThe Owning Storage Processor parameter reports the name of the controller that handles IOsfor each LUN If a LUN is not currently handled by its normal (default) storage processors the nameof the default controller will be indicated as SP_B (default SP_A)rdquo

To identify LUNs that are not owned by their normal storage processor you simply need to list the Volume objects where the Owning Storage Processor parameter contains the string Default

Identifying Most Busy LUNs

To identify the LUNs that generate the most traffic on the disk array use the Read Byte Rate andWrite Byte Rate parameters of the LUN class that expose the data throughput for each LUN Usethese parameters to report on the total data traffic (per hour or per day) on each LUN in GB

To make sure that traffic is displayed cumulatively per hour select a time window of at least 12 hours in the graphwindow select at least 7 days to visualize per day cumulative data

1 In the Status tab click the Volume for which you need to check the LUNs activity then expandthe LUNs object to display the ReadWrite Byte Rate parameters

53Identifying Most Busy LUNs

BMC Performance Manager Express for EMC Disk Arrays

Version 2001

Selecting a LUNs ReadW rite Byte Rate Parameter

2 Click the History icon to automatically display a graph that shows the ReadWrite Byte Ratevalues collected for a selected parameter during the previous six hours You can customize thechart and table to show parameter history for different time periods

54Identifying Most Busy LUNs

BMC Performance Manager Express for EMC Disk Arrays

Version 2001

View ing a LUNs ReadW rite Byte Rate as a graph

Identifying a Storage Processor(Controllers) OverloadTo visualize the activity of a controller in an EMC disk array use the Processor Utilizationparameter of the SEN_EMC_CONTROLLER class A warning is issued when the processor utilizationgoes too high which means that the controllers cannot keep up with the load on the disk array It isthen important to identify what is overloading the controllers

The Response Time parameter of the SEN_EMC_CONTROLLER class represents the average time ittook the controller to process the read and write requests of the hosts The higher the ResponseTime goes the slower IOs the servers will get By default the solution triggers a warning when thecontroller takes more than 10 milliseconds on average to complete the IO requests and an alarmwhen the response time reaches 100 milliseconds

Monitoring the Efficiency of theCaching MechanismEach controller in an EMC disk array can be configured to use a specified amount of memory tocache the read andor write operations The solution reports the amount of memory configured byeach controller for the read and write operations

The Write Flush Byte Rate represents the rate in MBsec at which data is committed to the disk(ie physically written) This value is to be compared with the Write Byte Rate of the disk array

55Monitoring the Efficiency of the CachingMechanism

BMC Performance Manager Express for EMC Disk Arrays

Version 2001

Comparing W rite Flush Byte Rate w ith W rite Byte Rate

The Cache Dirty Pages Percentage parameter represents the amount in percentage of the writecache that has been modified by host write operations and not yet flushed to the disks Reaching100 means that write case is too small and cannot handle the flow of write operations

Checking the Cache Dirty Pages Percentage

Reclaiming Space of Unmapped(Unused) LUNsOver time as servers connected to a SAN get decommissioned administrators find an increasingnumber of unmapped LUNs or volumes that are no longer used by any server These LUNs whileunused still occupy disk space in the disk array Being able to identify such unmapped LUNs andreclaim the disk space uselessly consumed by these LUNs will help administrators avoid unnecessaryupgrades and extensions of their disk arrays

56Reporting a Disk Space Consumption

BMC Performance Manager Express for EMC Disk Arrays

Version 2001

Reporting a Disk SpaceConsumptionMaking sure that a disk array has enough remaining disk space available is critical for severalreasons

middot SAN administrators want to make sure to be able to provision disk space for new servers whenrequested as quickly as possible

middot The disk array itself may need additional disk space for specific features to work properly likeautomatic snapshots mirroring etc

middot If thin provisioning is used the remaining disk space becomes dramatically critical since theinability to allocate additional space to a LUN when requested by the subscriber host will lead tocatastrophic data loss and corruption

The disk space used is permanently monitored for each storage pool The Subscribed Capacityparameter of the Pool class represents the amount of disk space that has been made available tothe subscriber hosts or in other words the amount of disk space that is seen by the serversconnected to disk array

The Consumed Capacity parameter of the SEN_EMC_STORAGEPOOLS class represents the actualspace usage in the storage pool For thin pools (when thin provisioning is enabled on the disk array)this value is normally lower than the Subscribed Capacity as it is the main purpose of thinprovisioning For traditional pools the Consumed Capacity parameters has the same value as theSubscribed Capacity parameter as the entirety of the subscribed disk space is fully allocated inthe storage pool

The Consumed Capacity Percentage parameter is the most critical one as a storage pool usagenearing 100 means that SAN administrators will not be able to create new LUNs in the storagepool By default no alarm or warning threshold is set on this parameter as the fullness of a storagepool may be a normal situation However you can set alert thresholds on this parameter as it fitsyour needs

57Reporting a Disk Space Consumption

BMC Performance Manager Express for EMC Disk Arrays

Version 2001

Verifying the Available Disk Space in the Storage Pool of your EMC DiskArrays

1 In the Configure tab select an element group in the tree view (the main ldquoInfrastructurerdquogroup for example)

2 Click on the Reports tab

3 Create a report for the last 24 hours top 50 values of the Array|Storage Pools|Disk Group|Storage Pool|Consumed Capacity Percentage parameter of the EMC Disk Arraysapplication class for the BMC Performance Manager Express for EMC Disk Arrays by SentrySoftware solution

Report ndash Disk Space Consumption

Reporting the Total Traffic on anHourly or Daily BasisBMC Performance Manager Express for EMC Disk Arrays not only monitors the traffic and activity ofthe disk array controllers LUNs and physical disks in MBsec but also in GB per hour or per day Theexact amount of data that was read or written to the disk array LUN or physical disk is calculated foreach hour of the day and each day of the week

Each data rate parameter in MBsec is accompanied by a non-rate one in GB These parameters areldquocumulativerdquo their instantaneous value has no meaning and they need to be visualized in a longperiod of time (instead of Read Byte Rate or Write Byte Rate)

58Reporting the Total Traffic on an Hourly orDaily Basis

Setting thresholds

Whenever relevant BMC Performance Manager Express for EMC Disk Arrays automatically setsthresholds for parameters If you prefer a more fault-tolerant monitoring you can modify thethresholds of each parameter through the Configure tab gt Edit Thresholds

It is strongly recommended to wait for all the storage objects to be discovered before setting threshold values to avoidhaving to enter thresholds for each occurrence of the application class

To modify the parameter thresholds of several storage objects of an element

60Setting thresholds

BMC Performance Manager Express for EMC Disk Arrays

Version 2001

1 In the Configure tab click on the Storage (ltplatformgt) or the instance icon gt Edit

Thresholds Properties and Credentials

Any modification to the thresholds or any other properties of elements created using the Element

Profile mode is to be done using the Element Profile route or by clicking Override Profile

2 Uncheck the Warning and Alarm boxes for all the parameters for which you want to disablethe alert conditions

3 Check the Warning and Alarm boxes for all the parameters for which you want to enable thealert conditions You will then have to manually enter the threshold values and check the Activebox In the example below a Warning will be triggered if Status is greater than 1 an alarm willbe triggered when greater than 2

Modifying threshold values

4 Click Save

5 The Success changes have been saved message indicates that the modifications have beenregistered

Alerts are displayed by the parameter whose thresholds are modified

Viewing the Overall Activity of aDisk ArrayIn order to visualize the activity of a disk array use the Read Byte Rate and Write Byte Rate ofthe SEN_EMC_ARRAY class These parameters represent the overall traffic in megabytes per secondfor each monitored array or more precisely each EMC disk array that is exposed through the EMCSMI-S Provider (see the EMC_SMI-S_Provider section of the Installation Guide for more informationabout the EMC SMI-S Provider)

62Viewing the Overall Activity of a Disk Array

BMC Performance Manager Express for EMC Disk Arrays

Version 2001

Viewing a Disk Array Activity

1 Click the Status tab in Portal

2 Click the array icon in the tree view to visualize its current activity

Selecting a Disk Array Parameter

Managing Baselines and KeyPerformance IndicatorsIn order to facilitate the detection of abnormalities on your monitored environment BMCProactiveNet calculates baselines per parameter (metrics or attributes) based on values collectedover a specified period of time to determine a normal operating range When the collected values forthese parameters are out of range an alert is triggered

Some parameters are identified by default as Key Performance Indicators and therefore automaticallyincluded in the base lining calculation

42Managing Baselines and Key PerformanceIndicators

BMC Performance Manager Express for EMC Disk Arrays

Version 2001

Managing baselines

The baseline is the expected normal operating range for a metric or attribute of a monitor

The baseline is calculated by collecting the values for a monitorrsquos attributes and metrics over aspecified time period and establishing a low baseline value (consisting of the 10th percentile of all thevalues for a given time period) and a high baseline value (consisting of the 90th percentile of all thevalues for a given time period) taking a weighted average of these values over time A higher weightis given to the latest data being factored into the baseline average The accuracy of the baselineimproves over time

Requirements for baseline generation

For baselines to be generated for an attribute that abnormality threshold means that the thresholdexists and is not suppressed Additionally if the Key Performance Indicator (KPI) mode is active only those attributes that have anactive abnormality threshold and are also KPI attributes will have baselines generated for them

Absolute thresholds (with outside baseline) or signature thresholds do not satisfy these requirements

Managing Key Performance Indicators

The KPI attribute of a parameter can be activated or deactivated manually through the BMCProactiveNet Administration Console In this PM some parameters or attributes have beendesignated as important indicators of performance (KPIs) We do not recommend that these defaultsettings are modified

However advanced users may activate or deactivate KPIs from the BMC ProactiveNet AdministrationConsole

To add or remove Key Performance Indicator (KPI) attributes for amonitor type

1 In the Administration Console from the menu bar choose Tools gt KPI AdministrationThe KPI Administration dialog box is displayed

2 From the Monitor Type list choose the monitor type for which you want to add or remove KPIattributes A list of attributes for the selected monitor type is displayed

3 In the KPI column for the attributes that you want to add or remove as Key PerformanceIndicators

middot select the KPI check box to add the corresponding attribute as a KPI

middot deselect the KPI check box to remove the corresponding attribute from the KPIs for thatmonitor type

For complete and detailed information on this procedure please refer to the BMC ProactiveNet documentation availablefrom BMC Web site

BMC Performance Manager Express for EMC Disk Arrays monitors all of the performance metrics andusage statistics of your EMC disk arrays such as file disk space usage storage controller utilizationIOs on the diskscontrollersvolumes etc It continuously monitors the activity of each array and isalso able to build reports on past utilization statistics

To setup a complete monitoring of the array we strongly recommend you to also use BMCPerformance Manager Express for Hardware that covers all the physical aspect of the EMC diskarrays (status of the disks ports temperature power supplies power consumption etc)

This chapter explains how to use each monitoring tool ie a separate application class within theBMC Performance Manager Express for EMC Disk Arrays by Sentry Software solution

BMC Performance Manager Express for EMC Disk Arrays is a Performance Manager specifically designedfor BMC Portal consequently it uses the same common features and procedures of BMCreg Portal Thisdocument assumes that the user knows how to use the Portal and therefore explains procedures onlyrelated to BMC Performance Manager Express for EMC Disk Arrays and not on how to add ElementsElement Profiles etc Please refer to the BMC Portal documentation for details on how to use the Portal

Checking Available Spare Disks

To avoid any loss of critical data it is essential for a disk array to always maintain a pool of sparedisks that can replace the faulty disk when a disk failure occurs A disk array without any left sparedisk will not be able to keep the level of data safety and performance in case of a disk failure

The Spare Disk Count parameter of the SEN_EMC_ARRAY class reports the number of spare disksavailable for each disk array monitored with the solution By default a warning is triggered when nospare disk is available (Spare Disk Count is set to zero)

Verifying the Number of Available Spare Disks in Your EMC Disk Arrays

49Checking Available Spare Disks

BMC Performance Manager Express for EMC Disk Arrays

Version 2001

1 Select an element group in the tree view (the main Infrastructure group for example)

2 Click the Reports tab Create a report for the last 24 hours bottom 50 values of the Array|Spare Disk Count parameter of the EMC Disk Arrays application class for the BMC PerformanceManager Express for EMC Disk Arrays by Sentry Software solution

Detecting OversubscriptionSituations (Thin Provisioning)We call an oversubscription situation when

1 The storage pool is configured for thin provisioning (ldquothin storage poolrdquo)

2 The storage pool is oversubscribed ie the total disk space visible to the hosts (subscribers) isgreater than its actual capacity (this situation is normal for a thin pool since it is its very purpose)

3 The storage pool actual consumed capacity is nearing 100

Such situation is highly critical because the inability to allocate additional space to a LUN whenrequested by the subscriber host will lead to catastrophic data loss and corruption

When the conditions described above are met the solution sets the Oversubscription Situationparameter to 1 automatically raising a warning By default the warning for OversubscriptionSituation is issued when the Consumed Capacity Percentage parameter goes above 100 Thisthreshold can be configured in the input properties of the solution

50Detecting Oversubscription Situations (ThinProvisioning)

BMC Performance Manager Express for EMC Disk Arrays

Version 2001

Configuring Oversubscription Threshold

1 Click the EMC Disk Arrays icon and then the Configure tab

2 Edit the Oversubscription Situation Threshold () property to the appropriate value Whenthe Oversubscription Situation parameter triggers a warning it is highly recommended thatthe SAN administrators add capacity to the storage pool as soon as possible

Diagnosing Slow LUNs

If a system administrator complains that his servers are experiencing slow IOs performance and thatit is caused by the SAN you may want to verify the actual response time of the LUNs the server isrelying on

The Response Time parameter of the SEN_EMC_VOLUME class represents the average time it tookto complete the read and write operations on the LUN during the collection interval Typically theaverage response time is below 10 milliseconds You may also want to compare this value to theresponse time of the other LUNs to see whether one server is really getting worse IO performancethan another

Volume - Response Time Parameter

If the response time is low you will need to check the amount of data that is written and read onthis LUN The bad performance may simply be due to an abnormally large amount of data to processOtherwise the problem is maybe between the disk array and the server in the fiber links

51Enabling the Debug Mode

BMC Performance Manager Express for EMC Disk Arrays

Version 2001

Enabling the Debug Mode

By default BMC Performance Manager Express for EMC Disk Arrays sends only the most criticalinformation warning and error messages to the Application Collection Status parameter Mostoften this information is accurate enough to ensure that BMC Performance Manager Express for EMCDisk Arrays is functioning properly If you encounter an issue and wish to report it to customersupport you will be asked to enable the Debug Mode and provide the debug output to the supportteam

1 In the Configure tab gt under Tasks click Elements

2 Select the Element whose debug output you require and click Edit

3 Scroll down to Application Classes gt click the Application class for which you want toenable the debug mode gt click Edit

4 Select Yes from the drop-down Debug Mode list gt SaveBy default BMC Performance Manager Express for EMC Disk Arrays sends its debug output to RSM_HOMERSM(xx)serverrsmlogsen_debuglog

5 Wait for 15 minutes and then disable the debug mode by selecting No

6 Send the debug file to the support team

Pay attention to the file size -the debug output of BMC Performance Manager Express for EMC Disk Arrays could bevery large if enabled for several days

Identifying the Hosts that canAccess a LUNIn most SAN configurations each LUN belongs to a storage group whose host members are the onlyones authorized to access the LUN This is called LUN masking For each LUN the solution displaysits WWN the storage group to which it belongs to as well as the hosts member of this group Inmost cases identifying the storage group of a LUN is sufficient to recognize the server that is usingit

52Identifying LUNs not Owned by their Normal(Default) Storage Processor

BMC Performance Manager Express for EMC Disk Arrays

Version 2001

Identifying LUNs not Owned bytheir Normal (Default) StorageProcessorThe Owning Storage Processor parameter reports the name of the controller that handles IOsfor each LUN If a LUN is not currently handled by its normal (default) storage processors the nameof the default controller will be indicated as SP_B (default SP_A)rdquo

To identify LUNs that are not owned by their normal storage processor you simply need to list the Volume objects where the Owning Storage Processor parameter contains the string Default

Identifying Most Busy LUNs

To identify the LUNs that generate the most traffic on the disk array use the Read Byte Rate andWrite Byte Rate parameters of the LUN class that expose the data throughput for each LUN Usethese parameters to report on the total data traffic (per hour or per day) on each LUN in GB

To make sure that traffic is displayed cumulatively per hour select a time window of at least 12 hours in the graphwindow select at least 7 days to visualize per day cumulative data

1 In the Status tab click the Volume for which you need to check the LUNs activity then expandthe LUNs object to display the ReadWrite Byte Rate parameters

Version 2001

View ing a LUNs ReadW rite Byte Rate as a graph

Identifying a Storage Processor(Controllers) OverloadTo visualize the activity of a controller in an EMC disk array use the Processor Utilizationparameter of the SEN_EMC_CONTROLLER class A warning is issued when the processor utilizationgoes too high which means that the controllers cannot keep up with the load on the disk array It isthen important to identify what is overloading the controllers

The Response Time parameter of the SEN_EMC_CONTROLLER class represents the average time ittook the controller to process the read and write requests of the hosts The higher the ResponseTime goes the slower IOs the servers will get By default the solution triggers a warning when thecontroller takes more than 10 milliseconds on average to complete the IO requests and an alarmwhen the response time reaches 100 milliseconds

Monitoring the Efficiency of theCaching MechanismEach controller in an EMC disk array can be configured to use a specified amount of memory tocache the read andor write operations The solution reports the amount of memory configured byeach controller for the read and write operations

The Write Flush Byte Rate represents the rate in MBsec at which data is committed to the disk(ie physically written) This value is to be compared with the Write Byte Rate of the disk array

55Monitoring the Efficiency of the CachingMechanism

BMC Performance Manager Express for EMC Disk Arrays

Version 2001

Comparing W rite Flush Byte Rate w ith W rite Byte Rate

The Cache Dirty Pages Percentage parameter represents the amount in percentage of the writecache that has been modified by host write operations and not yet flushed to the disks Reaching100 means that write case is too small and cannot handle the flow of write operations

Checking the Cache Dirty Pages Percentage

Reclaiming Space of Unmapped(Unused) LUNsOver time as servers connected to a SAN get decommissioned administrators find an increasingnumber of unmapped LUNs or volumes that are no longer used by any server These LUNs whileunused still occupy disk space in the disk array Being able to identify such unmapped LUNs andreclaim the disk space uselessly consumed by these LUNs will help administrators avoid unnecessaryupgrades and extensions of their disk arrays

56Reporting a Disk Space Consumption

BMC Performance Manager Express for EMC Disk Arrays

Version 2001

Reporting a Disk SpaceConsumptionMaking sure that a disk array has enough remaining disk space available is critical for severalreasons

middot SAN administrators want to make sure to be able to provision disk space for new servers whenrequested as quickly as possible

middot The disk array itself may need additional disk space for specific features to work properly likeautomatic snapshots mirroring etc

middot If thin provisioning is used the remaining disk space becomes dramatically critical since theinability to allocate additional space to a LUN when requested by the subscriber host will lead tocatastrophic data loss and corruption

The disk space used is permanently monitored for each storage pool The Subscribed Capacityparameter of the Pool class represents the amount of disk space that has been made available tothe subscriber hosts or in other words the amount of disk space that is seen by the serversconnected to disk array

The Consumed Capacity parameter of the SEN_EMC_STORAGEPOOLS class represents the actualspace usage in the storage pool For thin pools (when thin provisioning is enabled on the disk array)this value is normally lower than the Subscribed Capacity as it is the main purpose of thinprovisioning For traditional pools the Consumed Capacity parameters has the same value as theSubscribed Capacity parameter as the entirety of the subscribed disk space is fully allocated inthe storage pool

The Consumed Capacity Percentage parameter is the most critical one as a storage pool usagenearing 100 means that SAN administrators will not be able to create new LUNs in the storagepool By default no alarm or warning threshold is set on this parameter as the fullness of a storagepool may be a normal situation However you can set alert thresholds on this parameter as it fitsyour needs

Managing Baselines and KeyPerformance IndicatorsIn order to facilitate the detection of abnormalities on your monitored environment BMCProactiveNet calculates baselines per parameter (metrics or attributes) based on values collectedover a specified period of time to determine a normal operating range When the collected values forthese parameters are out of range an alert is triggered

Some parameters are identified by default as Key Performance Indicators and therefore automaticallyincluded in the base lining calculation

42Managing Baselines and Key PerformanceIndicators

BMC Performance Manager Express for EMC Disk Arrays

Version 2001

Managing baselines

The baseline is the expected normal operating range for a metric or attribute of a monitor

The baseline is calculated by collecting the values for a monitorrsquos attributes and metrics over aspecified time period and establishing a low baseline value (consisting of the 10th percentile of all thevalues for a given time period) and a high baseline value (consisting of the 90th percentile of all thevalues for a given time period) taking a weighted average of these values over time A higher weightis given to the latest data being factored into the baseline average The accuracy of the baselineimproves over time

Requirements for baseline generation

For baselines to be generated for an attribute that abnormality threshold means that the thresholdexists and is not suppressed Additionally if the Key Performance Indicator (KPI) mode is active only those attributes that have anactive abnormality threshold and are also KPI attributes will have baselines generated for them

Absolute thresholds (with outside baseline) or signature thresholds do not satisfy these requirements

Managing Key Performance Indicators

The KPI attribute of a parameter can be activated or deactivated manually through the BMCProactiveNet Administration Console In this PM some parameters or attributes have beendesignated as important indicators of performance (KPIs) We do not recommend that these defaultsettings are modified

However advanced users may activate or deactivate KPIs from the BMC ProactiveNet AdministrationConsole

To add or remove Key Performance Indicator (KPI) attributes for amonitor type

1 In the Administration Console from the menu bar choose Tools gt KPI AdministrationThe KPI Administration dialog box is displayed

2 From the Monitor Type list choose the monitor type for which you want to add or remove KPIattributes A list of attributes for the selected monitor type is displayed

3 In the KPI column for the attributes that you want to add or remove as Key PerformanceIndicators

middot select the KPI check box to add the corresponding attribute as a KPI

middot deselect the KPI check box to remove the corresponding attribute from the KPIs for thatmonitor type

For complete and detailed information on this procedure please refer to the BMC ProactiveNet documentation availablefrom BMC Web site

BMC Performance Manager Express for EMC Disk Arrays

Version 2001

BMC Performance Manager Express for EMC Disk Arrays monitors all of the performance metrics andusage statistics of your EMC disk arrays such as file disk space usage storage controller utilizationIOs on the diskscontrollersvolumes etc It continuously monitors the activity of each array and isalso able to build reports on past utilization statistics

To setup a complete monitoring of the array we strongly recommend you to also use BMCPerformance Manager Express for Hardware that covers all the physical aspect of the EMC diskarrays (status of the disks ports temperature power supplies power consumption etc)

This chapter explains how to use each monitoring tool ie a separate application class within theBMC Performance Manager Express for EMC Disk Arrays by Sentry Software solution

BMC Performance Manager Express for EMC Disk Arrays is a Performance Manager specifically designedfor BMC Portal consequently it uses the same common features and procedures of BMCreg Portal Thisdocument assumes that the user knows how to use the Portal and therefore explains procedures onlyrelated to BMC Performance Manager Express for EMC Disk Arrays and not on how to add ElementsElement Profiles etc Please refer to the BMC Portal documentation for details on how to use the Portal

Checking Available Spare Disks

To avoid any loss of critical data it is essential for a disk array to always maintain a pool of sparedisks that can replace the faulty disk when a disk failure occurs A disk array without any left sparedisk will not be able to keep the level of data safety and performance in case of a disk failure

The Spare Disk Count parameter of the SEN_EMC_ARRAY class reports the number of spare disksavailable for each disk array monitored with the solution By default a warning is triggered when nospare disk is available (Spare Disk Count is set to zero)

Verifying the Number of Available Spare Disks in Your EMC Disk Arrays

49Checking Available Spare Disks

BMC Performance Manager Express for EMC Disk Arrays

Version 2001

1 Select an element group in the tree view (the main Infrastructure group for example)

2 Click the Reports tab Create a report for the last 24 hours bottom 50 values of the Array|Spare Disk Count parameter of the EMC Disk Arrays application class for the BMC PerformanceManager Express for EMC Disk Arrays by Sentry Software solution

Report ndash Available Spare Disks

Detecting OversubscriptionSituations (Thin Provisioning)We call an oversubscription situation when

1 The storage pool is configured for thin provisioning (ldquothin storage poolrdquo)

2 The storage pool is oversubscribed ie the total disk space visible to the hosts (subscribers) isgreater than its actual capacity (this situation is normal for a thin pool since it is its very purpose)

3 The storage pool actual consumed capacity is nearing 100

Such situation is highly critical because the inability to allocate additional space to a LUN whenrequested by the subscriber host will lead to catastrophic data loss and corruption

When the conditions described above are met the solution sets the Oversubscription Situationparameter to 1 automatically raising a warning By default the warning for OversubscriptionSituation is issued when the Consumed Capacity Percentage parameter goes above 100 Thisthreshold can be configured in the input properties of the solution

50Detecting Oversubscription Situations (ThinProvisioning)

BMC Performance Manager Express for EMC Disk Arrays

Version 2001

Configuring Oversubscription Threshold

1 Click the EMC Disk Arrays icon and then the Configure tab

2 Edit the Oversubscription Situation Threshold () property to the appropriate value Whenthe Oversubscription Situation parameter triggers a warning it is highly recommended thatthe SAN administrators add capacity to the storage pool as soon as possible

Diagnosing Slow LUNs

If a system administrator complains that his servers are experiencing slow IOs performance and thatit is caused by the SAN you may want to verify the actual response time of the LUNs the server isrelying on

The Response Time parameter of the SEN_EMC_VOLUME class represents the average time it tookto complete the read and write operations on the LUN during the collection interval Typically theaverage response time is below 10 milliseconds You may also want to compare this value to theresponse time of the other LUNs to see whether one server is really getting worse IO performancethan another

Volume - Response Time Parameter

If the response time is low you will need to check the amount of data that is written and read onthis LUN The bad performance may simply be due to an abnormally large amount of data to processOtherwise the problem is maybe between the disk array and the server in the fiber links

51Enabling the Debug Mode

BMC Performance Manager Express for EMC Disk Arrays

Version 2001

Enabling the Debug Mode

By default BMC Performance Manager Express for EMC Disk Arrays sends only the most criticalinformation warning and error messages to the Application Collection Status parameter Mostoften this information is accurate enough to ensure that BMC Performance Manager Express for EMCDisk Arrays is functioning properly If you encounter an issue and wish to report it to customersupport you will be asked to enable the Debug Mode and provide the debug output to the supportteam

1 In the Configure tab gt under Tasks click Elements

2 Select the Element whose debug output you require and click Edit

3 Scroll down to Application Classes gt click the Application class for which you want toenable the debug mode gt click Edit

4 Select Yes from the drop-down Debug Mode list gt SaveBy default BMC Performance Manager Express for EMC Disk Arrays sends its debug output to RSM_HOMERSM(xx)serverrsmlogsen_debuglog

5 Wait for 15 minutes and then disable the debug mode by selecting No

6 Send the debug file to the support team

Pay attention to the file size -the debug output of BMC Performance Manager Express for EMC Disk Arrays could bevery large if enabled for several days

Identifying the Hosts that canAccess a LUNIn most SAN configurations each LUN belongs to a storage group whose host members are the onlyones authorized to access the LUN This is called LUN masking For each LUN the solution displaysits WWN the storage group to which it belongs to as well as the hosts member of this group Inmost cases identifying the storage group of a LUN is sufficient to recognize the server that is usingit

52Identifying LUNs not Owned by their Normal(Default) Storage Processor

BMC Performance Manager Express for EMC Disk Arrays

Version 2001

Identifying LUNs not Owned bytheir Normal (Default) StorageProcessorThe Owning Storage Processor parameter reports the name of the controller that handles IOsfor each LUN If a LUN is not currently handled by its normal (default) storage processors the nameof the default controller will be indicated as SP_B (default SP_A)rdquo

To identify LUNs that are not owned by their normal storage processor you simply need to list the Volume objects where the Owning Storage Processor parameter contains the string Default

Identifying Most Busy LUNs

To identify the LUNs that generate the most traffic on the disk array use the Read Byte Rate andWrite Byte Rate parameters of the LUN class that expose the data throughput for each LUN Usethese parameters to report on the total data traffic (per hour or per day) on each LUN in GB

To make sure that traffic is displayed cumulatively per hour select a time window of at least 12 hours in the graphwindow select at least 7 days to visualize per day cumulative data

1 In the Status tab click the Volume for which you need to check the LUNs activity then expandthe LUNs object to display the ReadWrite Byte Rate parameters

53Identifying Most Busy LUNs

BMC Performance Manager Express for EMC Disk Arrays

Version 2001

Selecting a LUNs ReadW rite Byte Rate Parameter

2 Click the History icon to automatically display a graph that shows the ReadWrite Byte Ratevalues collected for a selected parameter during the previous six hours You can customize thechart and table to show parameter history for different time periods

54Identifying Most Busy LUNs

BMC Performance Manager Express for EMC Disk Arrays

Version 2001

View ing a LUNs ReadW rite Byte Rate as a graph

Identifying a Storage Processor(Controllers) OverloadTo visualize the activity of a controller in an EMC disk array use the Processor Utilizationparameter of the SEN_EMC_CONTROLLER class A warning is issued when the processor utilizationgoes too high which means that the controllers cannot keep up with the load on the disk array It isthen important to identify what is overloading the controllers

The Response Time parameter of the SEN_EMC_CONTROLLER class represents the average time ittook the controller to process the read and write requests of the hosts The higher the ResponseTime goes the slower IOs the servers will get By default the solution triggers a warning when thecontroller takes more than 10 milliseconds on average to complete the IO requests and an alarmwhen the response time reaches 100 milliseconds

Monitoring the Efficiency of theCaching MechanismEach controller in an EMC disk array can be configured to use a specified amount of memory tocache the read andor write operations The solution reports the amount of memory configured byeach controller for the read and write operations

The Write Flush Byte Rate represents the rate in MBsec at which data is committed to the disk(ie physically written) This value is to be compared with the Write Byte Rate of the disk array

55Monitoring the Efficiency of the CachingMechanism

BMC Performance Manager Express for EMC Disk Arrays

Version 2001

Comparing W rite Flush Byte Rate w ith W rite Byte Rate

The Cache Dirty Pages Percentage parameter represents the amount in percentage of the writecache that has been modified by host write operations and not yet flushed to the disks Reaching100 means that write case is too small and cannot handle the flow of write operations

Checking the Cache Dirty Pages Percentage

Reclaiming Space of Unmapped(Unused) LUNsOver time as servers connected to a SAN get decommissioned administrators find an increasingnumber of unmapped LUNs or volumes that are no longer used by any server These LUNs whileunused still occupy disk space in the disk array Being able to identify such unmapped LUNs andreclaim the disk space uselessly consumed by these LUNs will help administrators avoid unnecessaryupgrades and extensions of their disk arrays

56Reporting a Disk Space Consumption

BMC Performance Manager Express for EMC Disk Arrays

Version 2001

Reporting a Disk SpaceConsumptionMaking sure that a disk array has enough remaining disk space available is critical for severalreasons

middot SAN administrators want to make sure to be able to provision disk space for new servers whenrequested as quickly as possible

middot The disk array itself may need additional disk space for specific features to work properly likeautomatic snapshots mirroring etc

middot If thin provisioning is used the remaining disk space becomes dramatically critical since theinability to allocate additional space to a LUN when requested by the subscriber host will lead tocatastrophic data loss and corruption

The disk space used is permanently monitored for each storage pool The Subscribed Capacityparameter of the Pool class represents the amount of disk space that has been made available tothe subscriber hosts or in other words the amount of disk space that is seen by the serversconnected to disk array

The Consumed Capacity parameter of the SEN_EMC_STORAGEPOOLS class represents the actualspace usage in the storage pool For thin pools (when thin provisioning is enabled on the disk array)this value is normally lower than the Subscribed Capacity as it is the main purpose of thinprovisioning For traditional pools the Consumed Capacity parameters has the same value as theSubscribed Capacity parameter as the entirety of the subscribed disk space is fully allocated inthe storage pool

The Consumed Capacity Percentage parameter is the most critical one as a storage pool usagenearing 100 means that SAN administrators will not be able to create new LUNs in the storagepool By default no alarm or warning threshold is set on this parameter as the fullness of a storagepool may be a normal situation However you can set alert thresholds on this parameter as it fitsyour needs

57Reporting a Disk Space Consumption

BMC Performance Manager Express for EMC Disk Arrays

Version 2001

Verifying the Available Disk Space in the Storage Pool of your EMC DiskArrays

1 In the Configure tab select an element group in the tree view (the main ldquoInfrastructurerdquogroup for example)

2 Click on the Reports tab

3 Create a report for the last 24 hours top 50 values of the Array|Storage Pools|Disk Group|Storage Pool|Consumed Capacity Percentage parameter of the EMC Disk Arraysapplication class for the BMC Performance Manager Express for EMC Disk Arrays by SentrySoftware solution

Report ndash Disk Space Consumption

Reporting the Total Traffic on anHourly or Daily BasisBMC Performance Manager Express for EMC Disk Arrays not only monitors the traffic and activity ofthe disk array controllers LUNs and physical disks in MBsec but also in GB per hour or per day Theexact amount of data that was read or written to the disk array LUN or physical disk is calculated foreach hour of the day and each day of the week

Each data rate parameter in MBsec is accompanied by a non-rate one in GB These parameters areldquocumulativerdquo their instantaneous value has no meaning and they need to be visualized in a longperiod of time (instead of Read Byte Rate or Write Byte Rate)

58Reporting the Total Traffic on an Hourly orDaily Basis

Setting thresholds

Whenever relevant BMC Performance Manager Express for EMC Disk Arrays automatically setsthresholds for parameters If you prefer a more fault-tolerant monitoring you can modify thethresholds of each parameter through the Configure tab gt Edit Thresholds

It is strongly recommended to wait for all the storage objects to be discovered before setting threshold values to avoidhaving to enter thresholds for each occurrence of the application class

To modify the parameter thresholds of several storage objects of an element

60Setting thresholds

BMC Performance Manager Express for EMC Disk Arrays

Version 2001

1 In the Configure tab click on the Storage (ltplatformgt) or the instance icon gt Edit

Thresholds Properties and Credentials

Any modification to the thresholds or any other properties of elements created using the Element

Profile mode is to be done using the Element Profile route or by clicking Override Profile

2 Uncheck the Warning and Alarm boxes for all the parameters for which you want to disablethe alert conditions

3 Check the Warning and Alarm boxes for all the parameters for which you want to enable thealert conditions You will then have to manually enter the threshold values and check the Activebox In the example below a Warning will be triggered if Status is greater than 1 an alarm willbe triggered when greater than 2

Modifying threshold values

4 Click Save

5 The Success changes have been saved message indicates that the modifications have beenregistered

Alerts are displayed by the parameter whose thresholds are modified

Viewing the Overall Activity of aDisk ArrayIn order to visualize the activity of a disk array use the Read Byte Rate and Write Byte Rate ofthe SEN_EMC_ARRAY class These parameters represent the overall traffic in megabytes per secondfor each monitored array or more precisely each EMC disk array that is exposed through the EMCSMI-S Provider (see the EMC_SMI-S_Provider section of the Installation Guide for more informationabout the EMC SMI-S Provider)

62Viewing the Overall Activity of a Disk Array

BMC Performance Manager Express for EMC Disk Arrays

Version 2001

Viewing a Disk Array Activity

1 Click the Status tab in Portal

2 Click the array icon in the tree view to visualize its current activity

Selecting a Disk Array Parameter

Managing Baselines and KeyPerformance IndicatorsIn order to facilitate the detection of abnormalities on your monitored environment BMCProactiveNet calculates baselines per parameter (metrics or attributes) based on values collectedover a specified period of time to determine a normal operating range When the collected values forthese parameters are out of range an alert is triggered

Some parameters are identified by default as Key Performance Indicators and therefore automaticallyincluded in the base lining calculation

42Managing Baselines and Key PerformanceIndicators

BMC Performance Manager Express for EMC Disk Arrays

Version 2001

Managing baselines

The baseline is the expected normal operating range for a metric or attribute of a monitor

The baseline is calculated by collecting the values for a monitorrsquos attributes and metrics over aspecified time period and establishing a low baseline value (consisting of the 10th percentile of all thevalues for a given time period) and a high baseline value (consisting of the 90th percentile of all thevalues for a given time period) taking a weighted average of these values over time A higher weightis given to the latest data being factored into the baseline average The accuracy of the baselineimproves over time

Requirements for baseline generation

For baselines to be generated for an attribute that abnormality threshold means that the thresholdexists and is not suppressed Additionally if the Key Performance Indicator (KPI) mode is active only those attributes that have anactive abnormality threshold and are also KPI attributes will have baselines generated for them

Absolute thresholds (with outside baseline) or signature thresholds do not satisfy these requirements

Managing Key Performance Indicators

The KPI attribute of a parameter can be activated or deactivated manually through the BMCProactiveNet Administration Console In this PM some parameters or attributes have beendesignated as important indicators of performance (KPIs) We do not recommend that these defaultsettings are modified

However advanced users may activate or deactivate KPIs from the BMC ProactiveNet AdministrationConsole

To add or remove Key Performance Indicator (KPI) attributes for amonitor type

1 In the Administration Console from the menu bar choose Tools gt KPI AdministrationThe KPI Administration dialog box is displayed

2 From the Monitor Type list choose the monitor type for which you want to add or remove KPIattributes A list of attributes for the selected monitor type is displayed

3 In the KPI column for the attributes that you want to add or remove as Key PerformanceIndicators

middot select the KPI check box to add the corresponding attribute as a KPI

middot deselect the KPI check box to remove the corresponding attribute from the KPIs for thatmonitor type

For complete and detailed information on this procedure please refer to the BMC ProactiveNet documentation availablefrom BMC Web site

BMC Performance Manager Express for EMC Disk Arrays monitors all of the performance metrics andusage statistics of your EMC disk arrays such as file disk space usage storage controller utilizationIOs on the diskscontrollersvolumes etc It continuously monitors the activity of each array and isalso able to build reports on past utilization statistics

To setup a complete monitoring of the array we strongly recommend you to also use BMCPerformance Manager Express for Hardware that covers all the physical aspect of the EMC diskarrays (status of the disks ports temperature power supplies power consumption etc)

This chapter explains how to use each monitoring tool ie a separate application class within theBMC Performance Manager Express for EMC Disk Arrays by Sentry Software solution

BMC Performance Manager Express for EMC Disk Arrays is a Performance Manager specifically designedfor BMC Portal consequently it uses the same common features and procedures of BMCreg Portal Thisdocument assumes that the user knows how to use the Portal and therefore explains procedures onlyrelated to BMC Performance Manager Express for EMC Disk Arrays and not on how to add ElementsElement Profiles etc Please refer to the BMC Portal documentation for details on how to use the Portal

Checking Available Spare Disks

To avoid any loss of critical data it is essential for a disk array to always maintain a pool of sparedisks that can replace the faulty disk when a disk failure occurs A disk array without any left sparedisk will not be able to keep the level of data safety and performance in case of a disk failure

The Spare Disk Count parameter of the SEN_EMC_ARRAY class reports the number of spare disksavailable for each disk array monitored with the solution By default a warning is triggered when nospare disk is available (Spare Disk Count is set to zero)

Verifying the Number of Available Spare Disks in Your EMC Disk Arrays

49Checking Available Spare Disks

BMC Performance Manager Express for EMC Disk Arrays

Version 2001

1 Select an element group in the tree view (the main Infrastructure group for example)

2 Click the Reports tab Create a report for the last 24 hours bottom 50 values of the Array|Spare Disk Count parameter of the EMC Disk Arrays application class for the BMC PerformanceManager Express for EMC Disk Arrays by Sentry Software solution

Detecting OversubscriptionSituations (Thin Provisioning)We call an oversubscription situation when

1 The storage pool is configured for thin provisioning (ldquothin storage poolrdquo)

2 The storage pool is oversubscribed ie the total disk space visible to the hosts (subscribers) isgreater than its actual capacity (this situation is normal for a thin pool since it is its very purpose)

3 The storage pool actual consumed capacity is nearing 100

Such situation is highly critical because the inability to allocate additional space to a LUN whenrequested by the subscriber host will lead to catastrophic data loss and corruption

When the conditions described above are met the solution sets the Oversubscription Situationparameter to 1 automatically raising a warning By default the warning for OversubscriptionSituation is issued when the Consumed Capacity Percentage parameter goes above 100 Thisthreshold can be configured in the input properties of the solution

50Detecting Oversubscription Situations (ThinProvisioning)

BMC Performance Manager Express for EMC Disk Arrays

Version 2001

Configuring Oversubscription Threshold

1 Click the EMC Disk Arrays icon and then the Configure tab

2 Edit the Oversubscription Situation Threshold () property to the appropriate value Whenthe Oversubscription Situation parameter triggers a warning it is highly recommended thatthe SAN administrators add capacity to the storage pool as soon as possible

Diagnosing Slow LUNs

If a system administrator complains that his servers are experiencing slow IOs performance and thatit is caused by the SAN you may want to verify the actual response time of the LUNs the server isrelying on

The Response Time parameter of the SEN_EMC_VOLUME class represents the average time it tookto complete the read and write operations on the LUN during the collection interval Typically theaverage response time is below 10 milliseconds You may also want to compare this value to theresponse time of the other LUNs to see whether one server is really getting worse IO performancethan another

Volume - Response Time Parameter

If the response time is low you will need to check the amount of data that is written and read onthis LUN The bad performance may simply be due to an abnormally large amount of data to processOtherwise the problem is maybe between the disk array and the server in the fiber links

51Enabling the Debug Mode

BMC Performance Manager Express for EMC Disk Arrays

Version 2001

Enabling the Debug Mode

By default BMC Performance Manager Express for EMC Disk Arrays sends only the most criticalinformation warning and error messages to the Application Collection Status parameter Mostoften this information is accurate enough to ensure that BMC Performance Manager Express for EMCDisk Arrays is functioning properly If you encounter an issue and wish to report it to customersupport you will be asked to enable the Debug Mode and provide the debug output to the supportteam

1 In the Configure tab gt under Tasks click Elements

2 Select the Element whose debug output you require and click Edit

3 Scroll down to Application Classes gt click the Application class for which you want toenable the debug mode gt click Edit

4 Select Yes from the drop-down Debug Mode list gt SaveBy default BMC Performance Manager Express for EMC Disk Arrays sends its debug output to RSM_HOMERSM(xx)serverrsmlogsen_debuglog

5 Wait for 15 minutes and then disable the debug mode by selecting No

6 Send the debug file to the support team

Pay attention to the file size -the debug output of BMC Performance Manager Express for EMC Disk Arrays could bevery large if enabled for several days

Identifying the Hosts that canAccess a LUNIn most SAN configurations each LUN belongs to a storage group whose host members are the onlyones authorized to access the LUN This is called LUN masking For each LUN the solution displaysits WWN the storage group to which it belongs to as well as the hosts member of this group Inmost cases identifying the storage group of a LUN is sufficient to recognize the server that is usingit

52Identifying LUNs not Owned by their Normal(Default) Storage Processor

BMC Performance Manager Express for EMC Disk Arrays

Version 2001

Identifying LUNs not Owned bytheir Normal (Default) StorageProcessorThe Owning Storage Processor parameter reports the name of the controller that handles IOsfor each LUN If a LUN is not currently handled by its normal (default) storage processors the nameof the default controller will be indicated as SP_B (default SP_A)rdquo

To identify LUNs that are not owned by their normal storage processor you simply need to list the Volume objects where the Owning Storage Processor parameter contains the string Default

Identifying Most Busy LUNs

To identify the LUNs that generate the most traffic on the disk array use the Read Byte Rate andWrite Byte Rate parameters of the LUN class that expose the data throughput for each LUN Usethese parameters to report on the total data traffic (per hour or per day) on each LUN in GB

To make sure that traffic is displayed cumulatively per hour select a time window of at least 12 hours in the graphwindow select at least 7 days to visualize per day cumulative data

1 In the Status tab click the Volume for which you need to check the LUNs activity then expandthe LUNs object to display the ReadWrite Byte Rate parameters

53Identifying Most Busy LUNs

Version 2001

View ing a LUNs ReadW rite Byte Rate as a graph

Identifying a Storage Processor(Controllers) OverloadTo visualize the activity of a controller in an EMC disk array use the Processor Utilizationparameter of the SEN_EMC_CONTROLLER class A warning is issued when the processor utilizationgoes too high which means that the controllers cannot keep up with the load on the disk array It isthen important to identify what is overloading the controllers

The Response Time parameter of the SEN_EMC_CONTROLLER class represents the average time ittook the controller to process the read and write requests of the hosts The higher the ResponseTime goes the slower IOs the servers will get By default the solution triggers a warning when thecontroller takes more than 10 milliseconds on average to complete the IO requests and an alarmwhen the response time reaches 100 milliseconds

Monitoring the Efficiency of theCaching MechanismEach controller in an EMC disk array can be configured to use a specified amount of memory tocache the read andor write operations The solution reports the amount of memory configured byeach controller for the read and write operations

The Write Flush Byte Rate represents the rate in MBsec at which data is committed to the disk(ie physically written) This value is to be compared with the Write Byte Rate of the disk array

55Monitoring the Efficiency of the CachingMechanism

BMC Performance Manager Express for EMC Disk Arrays

Version 2001

Comparing W rite Flush Byte Rate w ith W rite Byte Rate

The Cache Dirty Pages Percentage parameter represents the amount in percentage of the writecache that has been modified by host write operations and not yet flushed to the disks Reaching100 means that write case is too small and cannot handle the flow of write operations

Checking the Cache Dirty Pages Percentage

Reclaiming Space of Unmapped(Unused) LUNsOver time as servers connected to a SAN get decommissioned administrators find an increasingnumber of unmapped LUNs or volumes that are no longer used by any server These LUNs whileunused still occupy disk space in the disk array Being able to identify such unmapped LUNs andreclaim the disk space uselessly consumed by these LUNs will help administrators avoid unnecessaryupgrades and extensions of their disk arrays

56Reporting a Disk Space Consumption

BMC Performance Manager Express for EMC Disk Arrays

Version 2001

Reporting a Disk SpaceConsumptionMaking sure that a disk array has enough remaining disk space available is critical for severalreasons

middot SAN administrators want to make sure to be able to provision disk space for new servers whenrequested as quickly as possible

middot The disk array itself may need additional disk space for specific features to work properly likeautomatic snapshots mirroring etc

middot If thin provisioning is used the remaining disk space becomes dramatically critical since theinability to allocate additional space to a LUN when requested by the subscriber host will lead tocatastrophic data loss and corruption

The disk space used is permanently monitored for each storage pool The Subscribed Capacityparameter of the Pool class represents the amount of disk space that has been made available tothe subscriber hosts or in other words the amount of disk space that is seen by the serversconnected to disk array

The Consumed Capacity parameter of the SEN_EMC_STORAGEPOOLS class represents the actualspace usage in the storage pool For thin pools (when thin provisioning is enabled on the disk array)this value is normally lower than the Subscribed Capacity as it is the main purpose of thinprovisioning For traditional pools the Consumed Capacity parameters has the same value as theSubscribed Capacity parameter as the entirety of the subscribed disk space is fully allocated inthe storage pool

The Consumed Capacity Percentage parameter is the most critical one as a storage pool usagenearing 100 means that SAN administrators will not be able to create new LUNs in the storagepool By default no alarm or warning threshold is set on this parameter as the fullness of a storagepool may be a normal situation However you can set alert thresholds on this parameter as it fitsyour needs

Managing Baselines and KeyPerformance IndicatorsIn order to facilitate the detection of abnormalities on your monitored environment BMCProactiveNet calculates baselines per parameter (metrics or attributes) based on values collectedover a specified period of time to determine a normal operating range When the collected values forthese parameters are out of range an alert is triggered

Some parameters are identified by default as Key Performance Indicators and therefore automaticallyincluded in the base lining calculation

42Managing Baselines and Key PerformanceIndicators

BMC Performance Manager Express for EMC Disk Arrays

Version 2001

Managing baselines

The baseline is the expected normal operating range for a metric or attribute of a monitor

The baseline is calculated by collecting the values for a monitorrsquos attributes and metrics over aspecified time period and establishing a low baseline value (consisting of the 10th percentile of all thevalues for a given time period) and a high baseline value (consisting of the 90th percentile of all thevalues for a given time period) taking a weighted average of these values over time A higher weightis given to the latest data being factored into the baseline average The accuracy of the baselineimproves over time

Requirements for baseline generation

For baselines to be generated for an attribute that abnormality threshold means that the thresholdexists and is not suppressed Additionally if the Key Performance Indicator (KPI) mode is active only those attributes that have anactive abnormality threshold and are also KPI attributes will have baselines generated for them

Absolute thresholds (with outside baseline) or signature thresholds do not satisfy these requirements

Managing Key Performance Indicators

The KPI attribute of a parameter can be activated or deactivated manually through the BMCProactiveNet Administration Console In this PM some parameters or attributes have beendesignated as important indicators of performance (KPIs) We do not recommend that these defaultsettings are modified

However advanced users may activate or deactivate KPIs from the BMC ProactiveNet AdministrationConsole

To add or remove Key Performance Indicator (KPI) attributes for amonitor type

1 In the Administration Console from the menu bar choose Tools gt KPI AdministrationThe KPI Administration dialog box is displayed

2 From the Monitor Type list choose the monitor type for which you want to add or remove KPIattributes A list of attributes for the selected monitor type is displayed

3 In the KPI column for the attributes that you want to add or remove as Key PerformanceIndicators

middot select the KPI check box to add the corresponding attribute as a KPI

middot deselect the KPI check box to remove the corresponding attribute from the KPIs for thatmonitor type

For complete and detailed information on this procedure please refer to the BMC ProactiveNet documentation availablefrom BMC Web site

BMC Performance Manager Express for EMC Disk Arrays

Version 2001

BMC Performance Manager Express for EMC Disk Arrays monitors all of the performance metrics andusage statistics of your EMC disk arrays such as file disk space usage storage controller utilizationIOs on the diskscontrollersvolumes etc It continuously monitors the activity of each array and isalso able to build reports on past utilization statistics

To setup a complete monitoring of the array we strongly recommend you to also use BMCPerformance Manager Express for Hardware that covers all the physical aspect of the EMC diskarrays (status of the disks ports temperature power supplies power consumption etc)

This chapter explains how to use each monitoring tool ie a separate application class within theBMC Performance Manager Express for EMC Disk Arrays by Sentry Software solution

BMC Performance Manager Express for EMC Disk Arrays is a Performance Manager specifically designedfor BMC Portal consequently it uses the same common features and procedures of BMCreg Portal Thisdocument assumes that the user knows how to use the Portal and therefore explains procedures onlyrelated to BMC Performance Manager Express for EMC Disk Arrays and not on how to add ElementsElement Profiles etc Please refer to the BMC Portal documentation for details on how to use the Portal

Checking Available Spare Disks

To avoid any loss of critical data it is essential for a disk array to always maintain a pool of sparedisks that can replace the faulty disk when a disk failure occurs A disk array without any left sparedisk will not be able to keep the level of data safety and performance in case of a disk failure

The Spare Disk Count parameter of the SEN_EMC_ARRAY class reports the number of spare disksavailable for each disk array monitored with the solution By default a warning is triggered when nospare disk is available (Spare Disk Count is set to zero)

Verifying the Number of Available Spare Disks in Your EMC Disk Arrays

49Checking Available Spare Disks

BMC Performance Manager Express for EMC Disk Arrays

Version 2001

1 Select an element group in the tree view (the main Infrastructure group for example)

2 Click the Reports tab Create a report for the last 24 hours bottom 50 values of the Array|Spare Disk Count parameter of the EMC Disk Arrays application class for the BMC PerformanceManager Express for EMC Disk Arrays by Sentry Software solution

Report ndash Available Spare Disks

Detecting OversubscriptionSituations (Thin Provisioning)We call an oversubscription situation when

1 The storage pool is configured for thin provisioning (ldquothin storage poolrdquo)

2 The storage pool is oversubscribed ie the total disk space visible to the hosts (subscribers) isgreater than its actual capacity (this situation is normal for a thin pool since it is its very purpose)

3 The storage pool actual consumed capacity is nearing 100

Such situation is highly critical because the inability to allocate additional space to a LUN whenrequested by the subscriber host will lead to catastrophic data loss and corruption

When the conditions described above are met the solution sets the Oversubscription Situationparameter to 1 automatically raising a warning By default the warning for OversubscriptionSituation is issued when the Consumed Capacity Percentage parameter goes above 100 Thisthreshold can be configured in the input properties of the solution

50Detecting Oversubscription Situations (ThinProvisioning)

BMC Performance Manager Express for EMC Disk Arrays

Version 2001

Configuring Oversubscription Threshold

1 Click the EMC Disk Arrays icon and then the Configure tab

2 Edit the Oversubscription Situation Threshold () property to the appropriate value Whenthe Oversubscription Situation parameter triggers a warning it is highly recommended thatthe SAN administrators add capacity to the storage pool as soon as possible

Diagnosing Slow LUNs

If a system administrator complains that his servers are experiencing slow IOs performance and thatit is caused by the SAN you may want to verify the actual response time of the LUNs the server isrelying on

The Response Time parameter of the SEN_EMC_VOLUME class represents the average time it tookto complete the read and write operations on the LUN during the collection interval Typically theaverage response time is below 10 milliseconds You may also want to compare this value to theresponse time of the other LUNs to see whether one server is really getting worse IO performancethan another

Volume - Response Time Parameter

If the response time is low you will need to check the amount of data that is written and read onthis LUN The bad performance may simply be due to an abnormally large amount of data to processOtherwise the problem is maybe between the disk array and the server in the fiber links

51Enabling the Debug Mode

BMC Performance Manager Express for EMC Disk Arrays

Version 2001

Enabling the Debug Mode

By default BMC Performance Manager Express for EMC Disk Arrays sends only the most criticalinformation warning and error messages to the Application Collection Status parameter Mostoften this information is accurate enough to ensure that BMC Performance Manager Express for EMCDisk Arrays is functioning properly If you encounter an issue and wish to report it to customersupport you will be asked to enable the Debug Mode and provide the debug output to the supportteam

1 In the Configure tab gt under Tasks click Elements

2 Select the Element whose debug output you require and click Edit

3 Scroll down to Application Classes gt click the Application class for which you want toenable the debug mode gt click Edit

4 Select Yes from the drop-down Debug Mode list gt SaveBy default BMC Performance Manager Express for EMC Disk Arrays sends its debug output to RSM_HOMERSM(xx)serverrsmlogsen_debuglog

5 Wait for 15 minutes and then disable the debug mode by selecting No

6 Send the debug file to the support team

Pay attention to the file size -the debug output of BMC Performance Manager Express for EMC Disk Arrays could bevery large if enabled for several days

Identifying the Hosts that canAccess a LUNIn most SAN configurations each LUN belongs to a storage group whose host members are the onlyones authorized to access the LUN This is called LUN masking For each LUN the solution displaysits WWN the storage group to which it belongs to as well as the hosts member of this group Inmost cases identifying the storage group of a LUN is sufficient to recognize the server that is usingit

52Identifying LUNs not Owned by their Normal(Default) Storage Processor

BMC Performance Manager Express for EMC Disk Arrays

Version 2001

Identifying LUNs not Owned bytheir Normal (Default) StorageProcessorThe Owning Storage Processor parameter reports the name of the controller that handles IOsfor each LUN If a LUN is not currently handled by its normal (default) storage processors the nameof the default controller will be indicated as SP_B (default SP_A)rdquo

To identify LUNs that are not owned by their normal storage processor you simply need to list the Volume objects where the Owning Storage Processor parameter contains the string Default

Identifying Most Busy LUNs

To identify the LUNs that generate the most traffic on the disk array use the Read Byte Rate andWrite Byte Rate parameters of the LUN class that expose the data throughput for each LUN Usethese parameters to report on the total data traffic (per hour or per day) on each LUN in GB

To make sure that traffic is displayed cumulatively per hour select a time window of at least 12 hours in the graphwindow select at least 7 days to visualize per day cumulative data

1 In the Status tab click the Volume for which you need to check the LUNs activity then expandthe LUNs object to display the ReadWrite Byte Rate parameters

53Identifying Most Busy LUNs

BMC Performance Manager Express for EMC Disk Arrays

Version 2001

Selecting a LUNs ReadW rite Byte Rate Parameter

2 Click the History icon to automatically display a graph that shows the ReadWrite Byte Ratevalues collected for a selected parameter during the previous six hours You can customize thechart and table to show parameter history for different time periods

54Identifying Most Busy LUNs

BMC Performance Manager Express for EMC Disk Arrays

Version 2001

View ing a LUNs ReadW rite Byte Rate as a graph

Identifying a Storage Processor(Controllers) OverloadTo visualize the activity of a controller in an EMC disk array use the Processor Utilizationparameter of the SEN_EMC_CONTROLLER class A warning is issued when the processor utilizationgoes too high which means that the controllers cannot keep up with the load on the disk array It isthen important to identify what is overloading the controllers

The Response Time parameter of the SEN_EMC_CONTROLLER class represents the average time ittook the controller to process the read and write requests of the hosts The higher the ResponseTime goes the slower IOs the servers will get By default the solution triggers a warning when thecontroller takes more than 10 milliseconds on average to complete the IO requests and an alarmwhen the response time reaches 100 milliseconds

Monitoring the Efficiency of theCaching MechanismEach controller in an EMC disk array can be configured to use a specified amount of memory tocache the read andor write operations The solution reports the amount of memory configured byeach controller for the read and write operations

The Write Flush Byte Rate represents the rate in MBsec at which data is committed to the disk(ie physically written) This value is to be compared with the Write Byte Rate of the disk array

55Monitoring the Efficiency of the CachingMechanism

BMC Performance Manager Express for EMC Disk Arrays

Version 2001

Comparing W rite Flush Byte Rate w ith W rite Byte Rate

The Cache Dirty Pages Percentage parameter represents the amount in percentage of the writecache that has been modified by host write operations and not yet flushed to the disks Reaching100 means that write case is too small and cannot handle the flow of write operations

Checking the Cache Dirty Pages Percentage

Reclaiming Space of Unmapped(Unused) LUNsOver time as servers connected to a SAN get decommissioned administrators find an increasingnumber of unmapped LUNs or volumes that are no longer used by any server These LUNs whileunused still occupy disk space in the disk array Being able to identify such unmapped LUNs andreclaim the disk space uselessly consumed by these LUNs will help administrators avoid unnecessaryupgrades and extensions of their disk arrays

56Reporting a Disk Space Consumption

BMC Performance Manager Express for EMC Disk Arrays

Version 2001

Reporting a Disk SpaceConsumptionMaking sure that a disk array has enough remaining disk space available is critical for severalreasons

middot SAN administrators want to make sure to be able to provision disk space for new servers whenrequested as quickly as possible

middot The disk array itself may need additional disk space for specific features to work properly likeautomatic snapshots mirroring etc

middot If thin provisioning is used the remaining disk space becomes dramatically critical since theinability to allocate additional space to a LUN when requested by the subscriber host will lead tocatastrophic data loss and corruption

The disk space used is permanently monitored for each storage pool The Subscribed Capacityparameter of the Pool class represents the amount of disk space that has been made available tothe subscriber hosts or in other words the amount of disk space that is seen by the serversconnected to disk array

The Consumed Capacity parameter of the SEN_EMC_STORAGEPOOLS class represents the actualspace usage in the storage pool For thin pools (when thin provisioning is enabled on the disk array)this value is normally lower than the Subscribed Capacity as it is the main purpose of thinprovisioning For traditional pools the Consumed Capacity parameters has the same value as theSubscribed Capacity parameter as the entirety of the subscribed disk space is fully allocated inthe storage pool

The Consumed Capacity Percentage parameter is the most critical one as a storage pool usagenearing 100 means that SAN administrators will not be able to create new LUNs in the storagepool By default no alarm or warning threshold is set on this parameter as the fullness of a storagepool may be a normal situation However you can set alert thresholds on this parameter as it fitsyour needs

57Reporting a Disk Space Consumption

BMC Performance Manager Express for EMC Disk Arrays

Version 2001

Verifying the Available Disk Space in the Storage Pool of your EMC DiskArrays

1 In the Configure tab select an element group in the tree view (the main ldquoInfrastructurerdquogroup for example)

2 Click on the Reports tab

3 Create a report for the last 24 hours top 50 values of the Array|Storage Pools|Disk Group|Storage Pool|Consumed Capacity Percentage parameter of the EMC Disk Arraysapplication class for the BMC Performance Manager Express for EMC Disk Arrays by SentrySoftware solution

Report ndash Disk Space Consumption

Reporting the Total Traffic on anHourly or Daily BasisBMC Performance Manager Express for EMC Disk Arrays not only monitors the traffic and activity ofthe disk array controllers LUNs and physical disks in MBsec but also in GB per hour or per day Theexact amount of data that was read or written to the disk array LUN or physical disk is calculated foreach hour of the day and each day of the week

Each data rate parameter in MBsec is accompanied by a non-rate one in GB These parameters areldquocumulativerdquo their instantaneous value has no meaning and they need to be visualized in a longperiod of time (instead of Read Byte Rate or Write Byte Rate)

Setting thresholds

Whenever relevant BMC Performance Manager Express for EMC Disk Arrays automatically setsthresholds for parameters If you prefer a more fault-tolerant monitoring you can modify thethresholds of each parameter through the Configure tab gt Edit Thresholds

It is strongly recommended to wait for all the storage objects to be discovered before setting threshold values to avoidhaving to enter thresholds for each occurrence of the application class

To modify the parameter thresholds of several storage objects of an element

60Setting thresholds

BMC Performance Manager Express for EMC Disk Arrays

Version 2001

1 In the Configure tab click on the Storage (ltplatformgt) or the instance icon gt Edit

Thresholds Properties and Credentials

Any modification to the thresholds or any other properties of elements created using the Element

Profile mode is to be done using the Element Profile route or by clicking Override Profile

2 Uncheck the Warning and Alarm boxes for all the parameters for which you want to disablethe alert conditions

We strongly recommend that you create a specific adapter for each PM you need to integrate into BMCProactiveNet to enable the update of a single PM independently

Once created and imported the Adapter will be displayed in the Devices folder of the BMCProactiveNet Operations Console

Managing Baselines and KeyPerformance IndicatorsIn order to facilitate the detection of abnormalities on your monitored environment BMCProactiveNet calculates baselines per parameter (metrics or attributes) based on values collectedover a specified period of time to determine a normal operating range When the collected values forthese parameters are out of range an alert is triggered

Some parameters are identified by default as Key Performance Indicators and therefore automaticallyincluded in the base lining calculation

42Managing Baselines and Key PerformanceIndicators

BMC Performance Manager Express for EMC Disk Arrays

Version 2001

Managing baselines

The baseline is the expected normal operating range for a metric or attribute of a monitor

The baseline is calculated by collecting the values for a monitorrsquos attributes and metrics over aspecified time period and establishing a low baseline value (consisting of the 10th percentile of all thevalues for a given time period) and a high baseline value (consisting of the 90th percentile of all thevalues for a given time period) taking a weighted average of these values over time A higher weightis given to the latest data being factored into the baseline average The accuracy of the baselineimproves over time

Requirements for baseline generation

For baselines to be generated for an attribute that abnormality threshold means that the thresholdexists and is not suppressed Additionally if the Key Performance Indicator (KPI) mode is active only those attributes that have anactive abnormality threshold and are also KPI attributes will have baselines generated for them

Absolute thresholds (with outside baseline) or signature thresholds do not satisfy these requirements

Managing Key Performance Indicators

The KPI attribute of a parameter can be activated or deactivated manually through the BMCProactiveNet Administration Console In this PM some parameters or attributes have beendesignated as important indicators of performance (KPIs) We do not recommend that these defaultsettings are modified

However advanced users may activate or deactivate KPIs from the BMC ProactiveNet AdministrationConsole

To add or remove Key Performance Indicator (KPI) attributes for amonitor type

1 In the Administration Console from the menu bar choose Tools gt KPI AdministrationThe KPI Administration dialog box is displayed

2 From the Monitor Type list choose the monitor type for which you want to add or remove KPIattributes A list of attributes for the selected monitor type is displayed

3 In the KPI column for the attributes that you want to add or remove as Key PerformanceIndicators

middot select the KPI check box to add the corresponding attribute as a KPI

middot deselect the KPI check box to remove the corresponding attribute from the KPIs for thatmonitor type

For complete and detailed information on this procedure please refer to the BMC ProactiveNet documentation availablefrom BMC Web site

BMC Performance Manager Express for EMC Disk Arrays

Version 2001

BMC Performance Manager Express for EMC Disk Arrays monitors all of the performance metrics andusage statistics of your EMC disk arrays such as file disk space usage storage controller utilizationIOs on the diskscontrollersvolumes etc It continuously monitors the activity of each array and isalso able to build reports on past utilization statistics

To setup a complete monitoring of the array we strongly recommend you to also use BMCPerformance Manager Express for Hardware that covers all the physical aspect of the EMC diskarrays (status of the disks ports temperature power supplies power consumption etc)

This chapter explains how to use each monitoring tool ie a separate application class within theBMC Performance Manager Express for EMC Disk Arrays by Sentry Software solution

BMC Performance Manager Express for EMC Disk Arrays is a Performance Manager specifically designedfor BMC Portal consequently it uses the same common features and procedures of BMCreg Portal Thisdocument assumes that the user knows how to use the Portal and therefore explains procedures onlyrelated to BMC Performance Manager Express for EMC Disk Arrays and not on how to add ElementsElement Profiles etc Please refer to the BMC Portal documentation for details on how to use the Portal

Checking Available Spare Disks

To avoid any loss of critical data it is essential for a disk array to always maintain a pool of sparedisks that can replace the faulty disk when a disk failure occurs A disk array without any left sparedisk will not be able to keep the level of data safety and performance in case of a disk failure

The Spare Disk Count parameter of the SEN_EMC_ARRAY class reports the number of spare disksavailable for each disk array monitored with the solution By default a warning is triggered when nospare disk is available (Spare Disk Count is set to zero)

Verifying the Number of Available Spare Disks in Your EMC Disk Arrays

49Checking Available Spare Disks

BMC Performance Manager Express for EMC Disk Arrays

Version 2001

1 Select an element group in the tree view (the main Infrastructure group for example)

2 Click the Reports tab Create a report for the last 24 hours bottom 50 values of the Array|Spare Disk Count parameter of the EMC Disk Arrays application class for the BMC PerformanceManager Express for EMC Disk Arrays by Sentry Software solution

Report ndash Available Spare Disks

Detecting OversubscriptionSituations (Thin Provisioning)We call an oversubscription situation when

1 The storage pool is configured for thin provisioning (ldquothin storage poolrdquo)

2 The storage pool is oversubscribed ie the total disk space visible to the hosts (subscribers) isgreater than its actual capacity (this situation is normal for a thin pool since it is its very purpose)

3 The storage pool actual consumed capacity is nearing 100

Such situation is highly critical because the inability to allocate additional space to a LUN whenrequested by the subscriber host will lead to catastrophic data loss and corruption

When the conditions described above are met the solution sets the Oversubscription Situationparameter to 1 automatically raising a warning By default the warning for OversubscriptionSituation is issued when the Consumed Capacity Percentage parameter goes above 100 Thisthreshold can be configured in the input properties of the solution

50Detecting Oversubscription Situations (ThinProvisioning)

BMC Performance Manager Express for EMC Disk Arrays

Version 2001

Configuring Oversubscription Threshold

1 Click the EMC Disk Arrays icon and then the Configure tab

2 Edit the Oversubscription Situation Threshold () property to the appropriate value Whenthe Oversubscription Situation parameter triggers a warning it is highly recommended thatthe SAN administrators add capacity to the storage pool as soon as possible

Diagnosing Slow LUNs

If a system administrator complains that his servers are experiencing slow IOs performance and thatit is caused by the SAN you may want to verify the actual response time of the LUNs the server isrelying on

The Response Time parameter of the SEN_EMC_VOLUME class represents the average time it tookto complete the read and write operations on the LUN during the collection interval Typically theaverage response time is below 10 milliseconds You may also want to compare this value to theresponse time of the other LUNs to see whether one server is really getting worse IO performancethan another

Volume - Response Time Parameter

If the response time is low you will need to check the amount of data that is written and read onthis LUN The bad performance may simply be due to an abnormally large amount of data to processOtherwise the problem is maybe between the disk array and the server in the fiber links

51Enabling the Debug Mode

BMC Performance Manager Express for EMC Disk Arrays

Version 2001

Enabling the Debug Mode

By default BMC Performance Manager Express for EMC Disk Arrays sends only the most criticalinformation warning and error messages to the Application Collection Status parameter Mostoften this information is accurate enough to ensure that BMC Performance Manager Express for EMCDisk Arrays is functioning properly If you encounter an issue and wish to report it to customersupport you will be asked to enable the Debug Mode and provide the debug output to the supportteam

1 In the Configure tab gt under Tasks click Elements

2 Select the Element whose debug output you require and click Edit

3 Scroll down to Application Classes gt click the Application class for which you want toenable the debug mode gt click Edit

4 Select Yes from the drop-down Debug Mode list gt SaveBy default BMC Performance Manager Express for EMC Disk Arrays sends its debug output to RSM_HOMERSM(xx)serverrsmlogsen_debuglog

5 Wait for 15 minutes and then disable the debug mode by selecting No

6 Send the debug file to the support team

Pay attention to the file size -the debug output of BMC Performance Manager Express for EMC Disk Arrays could bevery large if enabled for several days

Identifying the Hosts that canAccess a LUNIn most SAN configurations each LUN belongs to a storage group whose host members are the onlyones authorized to access the LUN This is called LUN masking For each LUN the solution displaysits WWN the storage group to which it belongs to as well as the hosts member of this group Inmost cases identifying the storage group of a LUN is sufficient to recognize the server that is usingit

52Identifying LUNs not Owned by their Normal(Default) Storage Processor

BMC Performance Manager Express for EMC Disk Arrays

Version 2001

Identifying LUNs not Owned bytheir Normal (Default) StorageProcessorThe Owning Storage Processor parameter reports the name of the controller that handles IOsfor each LUN If a LUN is not currently handled by its normal (default) storage processors the nameof the default controller will be indicated as SP_B (default SP_A)rdquo

To identify LUNs that are not owned by their normal storage processor you simply need to list the Volume objects where the Owning Storage Processor parameter contains the string Default

Identifying Most Busy LUNs

To identify the LUNs that generate the most traffic on the disk array use the Read Byte Rate andWrite Byte Rate parameters of the LUN class that expose the data throughput for each LUN Usethese parameters to report on the total data traffic (per hour or per day) on each LUN in GB

To make sure that traffic is displayed cumulatively per hour select a time window of at least 12 hours in the graphwindow select at least 7 days to visualize per day cumulative data

1 In the Status tab click the Volume for which you need to check the LUNs activity then expandthe LUNs object to display the ReadWrite Byte Rate parameters

53Identifying Most Busy LUNs

2 Click the History icon to automatically display a graph that shows the ReadWrite Byte Ratevalues collected for a selected parameter during the previous six hours You can customize thechart and table to show parameter history for different time periods

54Identifying Most Busy LUNs

BMC Performance Manager Express for EMC Disk Arrays

Version 2001

View ing a LUNs ReadW rite Byte Rate as a graph

Identifying a Storage Processor(Controllers) OverloadTo visualize the activity of a controller in an EMC disk array use the Processor Utilizationparameter of the SEN_EMC_CONTROLLER class A warning is issued when the processor utilizationgoes too high which means that the controllers cannot keep up with the load on the disk array It isthen important to identify what is overloading the controllers

The Response Time parameter of the SEN_EMC_CONTROLLER class represents the average time ittook the controller to process the read and write requests of the hosts The higher the ResponseTime goes the slower IOs the servers will get By default the solution triggers a warning when thecontroller takes more than 10 milliseconds on average to complete the IO requests and an alarmwhen the response time reaches 100 milliseconds

Monitoring the Efficiency of theCaching MechanismEach controller in an EMC disk array can be configured to use a specified amount of memory tocache the read andor write operations The solution reports the amount of memory configured byeach controller for the read and write operations

The Write Flush Byte Rate represents the rate in MBsec at which data is committed to the disk(ie physically written) This value is to be compared with the Write Byte Rate of the disk array

55Monitoring the Efficiency of the CachingMechanism

BMC Performance Manager Express for EMC Disk Arrays

Version 2001

Comparing W rite Flush Byte Rate w ith W rite Byte Rate

The Cache Dirty Pages Percentage parameter represents the amount in percentage of the writecache that has been modified by host write operations and not yet flushed to the disks Reaching100 means that write case is too small and cannot handle the flow of write operations

Checking the Cache Dirty Pages Percentage

Reclaiming Space of Unmapped(Unused) LUNsOver time as servers connected to a SAN get decommissioned administrators find an increasingnumber of unmapped LUNs or volumes that are no longer used by any server These LUNs whileunused still occupy disk space in the disk array Being able to identify such unmapped LUNs andreclaim the disk space uselessly consumed by these LUNs will help administrators avoid unnecessaryupgrades and extensions of their disk arrays

56Reporting a Disk Space Consumption

BMC Performance Manager Express for EMC Disk Arrays

Version 2001

Reporting a Disk SpaceConsumptionMaking sure that a disk array has enough remaining disk space available is critical for severalreasons

middot SAN administrators want to make sure to be able to provision disk space for new servers whenrequested as quickly as possible

middot The disk array itself may need additional disk space for specific features to work properly likeautomatic snapshots mirroring etc

middot If thin provisioning is used the remaining disk space becomes dramatically critical since theinability to allocate additional space to a LUN when requested by the subscriber host will lead tocatastrophic data loss and corruption

The disk space used is permanently monitored for each storage pool The Subscribed Capacityparameter of the Pool class represents the amount of disk space that has been made available tothe subscriber hosts or in other words the amount of disk space that is seen by the serversconnected to disk array

The Consumed Capacity parameter of the SEN_EMC_STORAGEPOOLS class represents the actualspace usage in the storage pool For thin pools (when thin provisioning is enabled on the disk array)this value is normally lower than the Subscribed Capacity as it is the main purpose of thinprovisioning For traditional pools the Consumed Capacity parameters has the same value as theSubscribed Capacity parameter as the entirety of the subscribed disk space is fully allocated inthe storage pool

The Consumed Capacity Percentage parameter is the most critical one as a storage pool usagenearing 100 means that SAN administrators will not be able to create new LUNs in the storagepool By default no alarm or warning threshold is set on this parameter as the fullness of a storagepool may be a normal situation However you can set alert thresholds on this parameter as it fitsyour needs

57Reporting a Disk Space Consumption

We strongly recommend that you create a specific adapter for each PM you need to integrate into BMCProactiveNet to enable the update of a single PM independently

Once created and imported the Adapter will be displayed in the Devices folder of the BMCProactiveNet Operations Console

Managing Baselines and KeyPerformance IndicatorsIn order to facilitate the detection of abnormalities on your monitored environment BMCProactiveNet calculates baselines per parameter (metrics or attributes) based on values collectedover a specified period of time to determine a normal operating range When the collected values forthese parameters are out of range an alert is triggered

Some parameters are identified by default as Key Performance Indicators and therefore automaticallyincluded in the base lining calculation

42Managing Baselines and Key PerformanceIndicators

BMC Performance Manager Express for EMC Disk Arrays

Version 2001

Managing baselines

The baseline is the expected normal operating range for a metric or attribute of a monitor

The baseline is calculated by collecting the values for a monitorrsquos attributes and metrics over aspecified time period and establishing a low baseline value (consisting of the 10th percentile of all thevalues for a given time period) and a high baseline value (consisting of the 90th percentile of all thevalues for a given time period) taking a weighted average of these values over time A higher weightis given to the latest data being factored into the baseline average The accuracy of the baselineimproves over time

Requirements for baseline generation

For baselines to be generated for an attribute that abnormality threshold means that the thresholdexists and is not suppressed Additionally if the Key Performance Indicator (KPI) mode is active only those attributes that have anactive abnormality threshold and are also KPI attributes will have baselines generated for them

Absolute thresholds (with outside baseline) or signature thresholds do not satisfy these requirements

Managing Key Performance Indicators

The KPI attribute of a parameter can be activated or deactivated manually through the BMCProactiveNet Administration Console In this PM some parameters or attributes have beendesignated as important indicators of performance (KPIs) We do not recommend that these defaultsettings are modified

However advanced users may activate or deactivate KPIs from the BMC ProactiveNet AdministrationConsole

To add or remove Key Performance Indicator (KPI) attributes for amonitor type

1 In the Administration Console from the menu bar choose Tools gt KPI AdministrationThe KPI Administration dialog box is displayed

2 From the Monitor Type list choose the monitor type for which you want to add or remove KPIattributes A list of attributes for the selected monitor type is displayed

3 In the KPI column for the attributes that you want to add or remove as Key PerformanceIndicators

middot select the KPI check box to add the corresponding attribute as a KPI

middot deselect the KPI check box to remove the corresponding attribute from the KPIs for thatmonitor type

For complete and detailed information on this procedure please refer to the BMC ProactiveNet documentation availablefrom BMC Web site

BMC Performance Manager Express for EMC Disk Arrays

Version 2001

BMC Performance Manager Express for EMC Disk Arrays monitors all of the performance metrics andusage statistics of your EMC disk arrays such as file disk space usage storage controller utilizationIOs on the diskscontrollersvolumes etc It continuously monitors the activity of each array and isalso able to build reports on past utilization statistics

To setup a complete monitoring of the array we strongly recommend you to also use BMCPerformance Manager Express for Hardware that covers all the physical aspect of the EMC diskarrays (status of the disks ports temperature power supplies power consumption etc)

This chapter explains how to use each monitoring tool ie a separate application class within theBMC Performance Manager Express for EMC Disk Arrays by Sentry Software solution

BMC Performance Manager Express for EMC Disk Arrays is a Performance Manager specifically designedfor BMC Portal consequently it uses the same common features and procedures of BMCreg Portal Thisdocument assumes that the user knows how to use the Portal and therefore explains procedures onlyrelated to BMC Performance Manager Express for EMC Disk Arrays and not on how to add ElementsElement Profiles etc Please refer to the BMC Portal documentation for details on how to use the Portal

Checking Available Spare Disks

To avoid any loss of critical data it is essential for a disk array to always maintain a pool of sparedisks that can replace the faulty disk when a disk failure occurs A disk array without any left sparedisk will not be able to keep the level of data safety and performance in case of a disk failure

The Spare Disk Count parameter of the SEN_EMC_ARRAY class reports the number of spare disksavailable for each disk array monitored with the solution By default a warning is triggered when nospare disk is available (Spare Disk Count is set to zero)

Verifying the Number of Available Spare Disks in Your EMC Disk Arrays

49Checking Available Spare Disks

BMC Performance Manager Express for EMC Disk Arrays

Version 2001

1 Select an element group in the tree view (the main Infrastructure group for example)

2 Click the Reports tab Create a report for the last 24 hours bottom 50 values of the Array|Spare Disk Count parameter of the EMC Disk Arrays application class for the BMC PerformanceManager Express for EMC Disk Arrays by Sentry Software solution

Report ndash Available Spare Disks

Detecting OversubscriptionSituations (Thin Provisioning)We call an oversubscription situation when

1 The storage pool is configured for thin provisioning (ldquothin storage poolrdquo)

2 The storage pool is oversubscribed ie the total disk space visible to the hosts (subscribers) isgreater than its actual capacity (this situation is normal for a thin pool since it is its very purpose)

3 The storage pool actual consumed capacity is nearing 100

Such situation is highly critical because the inability to allocate additional space to a LUN whenrequested by the subscriber host will lead to catastrophic data loss and corruption

When the conditions described above are met the solution sets the Oversubscription Situationparameter to 1 automatically raising a warning By default the warning for OversubscriptionSituation is issued when the Consumed Capacity Percentage parameter goes above 100 Thisthreshold can be configured in the input properties of the solution

50Detecting Oversubscription Situations (ThinProvisioning)

BMC Performance Manager Express for EMC Disk Arrays

Version 2001

Configuring Oversubscription Threshold

1 Click the EMC Disk Arrays icon and then the Configure tab

2 Edit the Oversubscription Situation Threshold () property to the appropriate value Whenthe Oversubscription Situation parameter triggers a warning it is highly recommended thatthe SAN administrators add capacity to the storage pool as soon as possible

Diagnosing Slow LUNs

If a system administrator complains that his servers are experiencing slow IOs performance and thatit is caused by the SAN you may want to verify the actual response time of the LUNs the server isrelying on

The Response Time parameter of the SEN_EMC_VOLUME class represents the average time it tookto complete the read and write operations on the LUN during the collection interval Typically theaverage response time is below 10 milliseconds You may also want to compare this value to theresponse time of the other LUNs to see whether one server is really getting worse IO performancethan another

Volume - Response Time Parameter

If the response time is low you will need to check the amount of data that is written and read onthis LUN The bad performance may simply be due to an abnormally large amount of data to processOtherwise the problem is maybe between the disk array and the server in the fiber links

51Enabling the Debug Mode

BMC Performance Manager Express for EMC Disk Arrays

Version 2001

Enabling the Debug Mode

By default BMC Performance Manager Express for EMC Disk Arrays sends only the most criticalinformation warning and error messages to the Application Collection Status parameter Mostoften this information is accurate enough to ensure that BMC Performance Manager Express for EMCDisk Arrays is functioning properly If you encounter an issue and wish to report it to customersupport you will be asked to enable the Debug Mode and provide the debug output to the supportteam

1 In the Configure tab gt under Tasks click Elements

2 Select the Element whose debug output you require and click Edit

3 Scroll down to Application Classes gt click the Application class for which you want toenable the debug mode gt click Edit

4 Select Yes from the drop-down Debug Mode list gt SaveBy default BMC Performance Manager Express for EMC Disk Arrays sends its debug output to RSM_HOMERSM(xx)serverrsmlogsen_debuglog

5 Wait for 15 minutes and then disable the debug mode by selecting No

6 Send the debug file to the support team

Pay attention to the file size -the debug output of BMC Performance Manager Express for EMC Disk Arrays could bevery large if enabled for several days

Identifying the Hosts that canAccess a LUNIn most SAN configurations each LUN belongs to a storage group whose host members are the onlyones authorized to access the LUN This is called LUN masking For each LUN the solution displaysits WWN the storage group to which it belongs to as well as the hosts member of this group Inmost cases identifying the storage group of a LUN is sufficient to recognize the server that is usingit

52Identifying LUNs not Owned by their Normal(Default) Storage Processor

BMC Performance Manager Express for EMC Disk Arrays

Version 2001

Identifying LUNs not Owned bytheir Normal (Default) StorageProcessorThe Owning Storage Processor parameter reports the name of the controller that handles IOsfor each LUN If a LUN is not currently handled by its normal (default) storage processors the nameof the default controller will be indicated as SP_B (default SP_A)rdquo

To identify LUNs that are not owned by their normal storage processor you simply need to list the Volume objects where the Owning Storage Processor parameter contains the string Default

Identifying Most Busy LUNs

To identify the LUNs that generate the most traffic on the disk array use the Read Byte Rate andWrite Byte Rate parameters of the LUN class that expose the data throughput for each LUN Usethese parameters to report on the total data traffic (per hour or per day) on each LUN in GB

To make sure that traffic is displayed cumulatively per hour select a time window of at least 12 hours in the graphwindow select at least 7 days to visualize per day cumulative data

1 In the Status tab click the Volume for which you need to check the LUNs activity then expandthe LUNs object to display the ReadWrite Byte Rate parameters

53Identifying Most Busy LUNs

BMC Performance Manager Express for EMC Disk Arrays

Version 2001

Selecting a LUNs ReadW rite Byte Rate Parameter

2 Click the History icon to automatically display a graph that shows the ReadWrite Byte Ratevalues collected for a selected parameter during the previous six hours You can customize thechart and table to show parameter history for different time periods

54Identifying Most Busy LUNs

BMC Performance Manager Express for EMC Disk Arrays

Version 2001

View ing a LUNs ReadW rite Byte Rate as a graph

Identifying a Storage Processor(Controllers) OverloadTo visualize the activity of a controller in an EMC disk array use the Processor Utilizationparameter of the SEN_EMC_CONTROLLER class A warning is issued when the processor utilizationgoes too high which means that the controllers cannot keep up with the load on the disk array It isthen important to identify what is overloading the controllers

The Response Time parameter of the SEN_EMC_CONTROLLER class represents the average time ittook the controller to process the read and write requests of the hosts The higher the ResponseTime goes the slower IOs the servers will get By default the solution triggers a warning when thecontroller takes more than 10 milliseconds on average to complete the IO requests and an alarmwhen the response time reaches 100 milliseconds

Monitoring the Efficiency of theCaching MechanismEach controller in an EMC disk array can be configured to use a specified amount of memory tocache the read andor write operations The solution reports the amount of memory configured byeach controller for the read and write operations

The Write Flush Byte Rate represents the rate in MBsec at which data is committed to the disk(ie physically written) This value is to be compared with the Write Byte Rate of the disk array

55Monitoring the Efficiency of the CachingMechanism

BMC Performance Manager Express for EMC Disk Arrays

Version 2001

Comparing W rite Flush Byte Rate w ith W rite Byte Rate

The Cache Dirty Pages Percentage parameter represents the amount in percentage of the writecache that has been modified by host write operations and not yet flushed to the disks Reaching100 means that write case is too small and cannot handle the flow of write operations

Checking the Cache Dirty Pages Percentage

Reclaiming Space of Unmapped(Unused) LUNsOver time as servers connected to a SAN get decommissioned administrators find an increasingnumber of unmapped LUNs or volumes that are no longer used by any server These LUNs whileunused still occupy disk space in the disk array Being able to identify such unmapped LUNs andreclaim the disk space uselessly consumed by these LUNs will help administrators avoid unnecessaryupgrades and extensions of their disk arrays

56Reporting a Disk Space Consumption

BMC Performance Manager Express for EMC Disk Arrays

Version 2001

Reporting a Disk SpaceConsumptionMaking sure that a disk array has enough remaining disk space available is critical for severalreasons

middot SAN administrators want to make sure to be able to provision disk space for new servers whenrequested as quickly as possible

middot The disk array itself may need additional disk space for specific features to work properly likeautomatic snapshots mirroring etc

middot If thin provisioning is used the remaining disk space becomes dramatically critical since theinability to allocate additional space to a LUN when requested by the subscriber host will lead tocatastrophic data loss and corruption

The disk space used is permanently monitored for each storage pool The Subscribed Capacityparameter of the Pool class represents the amount of disk space that has been made available tothe subscriber hosts or in other words the amount of disk space that is seen by the serversconnected to disk array

The Consumed Capacity parameter of the SEN_EMC_STORAGEPOOLS class represents the actualspace usage in the storage pool For thin pools (when thin provisioning is enabled on the disk array)this value is normally lower than the Subscribed Capacity as it is the main purpose of thinprovisioning For traditional pools the Consumed Capacity parameters has the same value as theSubscribed Capacity parameter as the entirety of the subscribed disk space is fully allocated inthe storage pool

The Consumed Capacity Percentage parameter is the most critical one as a storage pool usagenearing 100 means that SAN administrators will not be able to create new LUNs in the storagepool By default no alarm or warning threshold is set on this parameter as the fullness of a storagepool may be a normal situation However you can set alert thresholds on this parameter as it fitsyour needs

57Reporting a Disk Space Consumption

We strongly recommend that you create a specific adapter for each PM you need to integrate into BMCProactiveNet to enable the update of a single PM independently

Once created and imported the Adapter will be displayed in the Devices folder of the BMCProactiveNet Operations Console

Managing Baselines and KeyPerformance IndicatorsIn order to facilitate the detection of abnormalities on your monitored environment BMCProactiveNet calculates baselines per parameter (metrics or attributes) based on values collectedover a specified period of time to determine a normal operating range When the collected values forthese parameters are out of range an alert is triggered

Some parameters are identified by default as Key Performance Indicators and therefore automaticallyincluded in the base lining calculation

42Managing Baselines and Key PerformanceIndicators

BMC Performance Manager Express for EMC Disk Arrays

Version 2001

Managing baselines

The baseline is the expected normal operating range for a metric or attribute of a monitor

The baseline is calculated by collecting the values for a monitorrsquos attributes and metrics over aspecified time period and establishing a low baseline value (consisting of the 10th percentile of all thevalues for a given time period) and a high baseline value (consisting of the 90th percentile of all thevalues for a given time period) taking a weighted average of these values over time A higher weightis given to the latest data being factored into the baseline average The accuracy of the baselineimproves over time

Requirements for baseline generation

For baselines to be generated for an attribute that abnormality threshold means that the thresholdexists and is not suppressed Additionally if the Key Performance Indicator (KPI) mode is active only those attributes that have anactive abnormality threshold and are also KPI attributes will have baselines generated for them

Absolute thresholds (with outside baseline) or signature thresholds do not satisfy these requirements

Managing Key Performance Indicators

The KPI attribute of a parameter can be activated or deactivated manually through the BMCProactiveNet Administration Console In this PM some parameters or attributes have beendesignated as important indicators of performance (KPIs) We do not recommend that these defaultsettings are modified

However advanced users may activate or deactivate KPIs from the BMC ProactiveNet AdministrationConsole

To add or remove Key Performance Indicator (KPI) attributes for amonitor type

1 In the Administration Console from the menu bar choose Tools gt KPI AdministrationThe KPI Administration dialog box is displayed

2 From the Monitor Type list choose the monitor type for which you want to add or remove KPIattributes A list of attributes for the selected monitor type is displayed

3 In the KPI column for the attributes that you want to add or remove as Key PerformanceIndicators

middot select the KPI check box to add the corresponding attribute as a KPI

middot deselect the KPI check box to remove the corresponding attribute from the KPIs for thatmonitor type

For complete and detailed information on this procedure please refer to the BMC ProactiveNet documentation availablefrom BMC Web site

BMC Performance Manager Express for EMC Disk Arrays

Version 2001

BMC Performance Manager Express for EMC Disk Arrays monitors all of the performance metrics andusage statistics of your EMC disk arrays such as file disk space usage storage controller utilizationIOs on the diskscontrollersvolumes etc It continuously monitors the activity of each array and isalso able to build reports on past utilization statistics

To setup a complete monitoring of the array we strongly recommend you to also use BMCPerformance Manager Express for Hardware that covers all the physical aspect of the EMC diskarrays (status of the disks ports temperature power supplies power consumption etc)

This chapter explains how to use each monitoring tool ie a separate application class within theBMC Performance Manager Express for EMC Disk Arrays by Sentry Software solution

BMC Performance Manager Express for EMC Disk Arrays is a Performance Manager specifically designedfor BMC Portal consequently it uses the same common features and procedures of BMCreg Portal Thisdocument assumes that the user knows how to use the Portal and therefore explains procedures onlyrelated to BMC Performance Manager Express for EMC Disk Arrays and not on how to add ElementsElement Profiles etc Please refer to the BMC Portal documentation for details on how to use the Portal

Checking Available Spare Disks

To avoid any loss of critical data it is essential for a disk array to always maintain a pool of sparedisks that can replace the faulty disk when a disk failure occurs A disk array without any left sparedisk will not be able to keep the level of data safety and performance in case of a disk failure

The Spare Disk Count parameter of the SEN_EMC_ARRAY class reports the number of spare disksavailable for each disk array monitored with the solution By default a warning is triggered when nospare disk is available (Spare Disk Count is set to zero)

Verifying the Number of Available Spare Disks in Your EMC Disk Arrays

1 The storage pool is configured for thin provisioning (ldquothin storage poolrdquo)

2 The storage pool is oversubscribed ie the total disk space visible to the hosts (subscribers) isgreater than its actual capacity (this situation is normal for a thin pool since it is its very purpose)

3 The storage pool actual consumed capacity is nearing 100

Such situation is highly critical because the inability to allocate additional space to a LUN whenrequested by the subscriber host will lead to catastrophic data loss and corruption

When the conditions described above are met the solution sets the Oversubscription Situationparameter to 1 automatically raising a warning By default the warning for OversubscriptionSituation is issued when the Consumed Capacity Percentage parameter goes above 100 Thisthreshold can be configured in the input properties of the solution

50Detecting Oversubscription Situations (ThinProvisioning)

BMC Performance Manager Express for EMC Disk Arrays

Version 2001

Configuring Oversubscription Threshold

1 Click the EMC Disk Arrays icon and then the Configure tab

2 Edit the Oversubscription Situation Threshold () property to the appropriate value Whenthe Oversubscription Situation parameter triggers a warning it is highly recommended thatthe SAN administrators add capacity to the storage pool as soon as possible

Diagnosing Slow LUNs

If a system administrator complains that his servers are experiencing slow IOs performance and thatit is caused by the SAN you may want to verify the actual response time of the LUNs the server isrelying on

The Response Time parameter of the SEN_EMC_VOLUME class represents the average time it tookto complete the read and write operations on the LUN during the collection interval Typically theaverage response time is below 10 milliseconds You may also want to compare this value to theresponse time of the other LUNs to see whether one server is really getting worse IO performancethan another

Volume - Response Time Parameter

If the response time is low you will need to check the amount of data that is written and read onthis LUN The bad performance may simply be due to an abnormally large amount of data to processOtherwise the problem is maybe between the disk array and the server in the fiber links

51Enabling the Debug Mode

BMC Performance Manager Express for EMC Disk Arrays

Version 2001

Enabling the Debug Mode

By default BMC Performance Manager Express for EMC Disk Arrays sends only the most criticalinformation warning and error messages to the Application Collection Status parameter Mostoften this information is accurate enough to ensure that BMC Performance Manager Express for EMCDisk Arrays is functioning properly If you encounter an issue and wish to report it to customersupport you will be asked to enable the Debug Mode and provide the debug output to the supportteam

1 In the Configure tab gt under Tasks click Elements

2 Select the Element whose debug output you require and click Edit

3 Scroll down to Application Classes gt click the Application class for which you want toenable the debug mode gt click Edit

4 Select Yes from the drop-down Debug Mode list gt SaveBy default BMC Performance Manager Express for EMC Disk Arrays sends its debug output to RSM_HOMERSM(xx)serverrsmlogsen_debuglog

5 Wait for 15 minutes and then disable the debug mode by selecting No

6 Send the debug file to the support team

Pay attention to the file size -the debug output of BMC Performance Manager Express for EMC Disk Arrays could bevery large if enabled for several days

Identifying the Hosts that canAccess a LUNIn most SAN configurations each LUN belongs to a storage group whose host members are the onlyones authorized to access the LUN This is called LUN masking For each LUN the solution displaysits WWN the storage group to which it belongs to as well as the hosts member of this group Inmost cases identifying the storage group of a LUN is sufficient to recognize the server that is usingit

52Identifying LUNs not Owned by their Normal(Default) Storage Processor

BMC Performance Manager Express for EMC Disk Arrays

Version 2001

Identifying LUNs not Owned bytheir Normal (Default) StorageProcessorThe Owning Storage Processor parameter reports the name of the controller that handles IOsfor each LUN If a LUN is not currently handled by its normal (default) storage processors the nameof the default controller will be indicated as SP_B (default SP_A)rdquo

To identify LUNs that are not owned by their normal storage processor you simply need to list the Volume objects where the Owning Storage Processor parameter contains the string Default

Identifying Most Busy LUNs

To identify the LUNs that generate the most traffic on the disk array use the Read Byte Rate andWrite Byte Rate parameters of the LUN class that expose the data throughput for each LUN Usethese parameters to report on the total data traffic (per hour or per day) on each LUN in GB

To make sure that traffic is displayed cumulatively per hour select a time window of at least 12 hours in the graphwindow select at least 7 days to visualize per day cumulative data

1 In the Status tab click the Volume for which you need to check the LUNs activity then expandthe LUNs object to display the ReadWrite Byte Rate parameters

53Identifying Most Busy LUNs

View ing a LUNs ReadW rite Byte Rate as a graph

Identifying a Storage Processor(Controllers) OverloadTo visualize the activity of a controller in an EMC disk array use the Processor Utilizationparameter of the SEN_EMC_CONTROLLER class A warning is issued when the processor utilizationgoes too high which means that the controllers cannot keep up with the load on the disk array It isthen important to identify what is overloading the controllers

The Response Time parameter of the SEN_EMC_CONTROLLER class represents the average time ittook the controller to process the read and write requests of the hosts The higher the ResponseTime goes the slower IOs the servers will get By default the solution triggers a warning when thecontroller takes more than 10 milliseconds on average to complete the IO requests and an alarmwhen the response time reaches 100 milliseconds

Monitoring the Efficiency of theCaching MechanismEach controller in an EMC disk array can be configured to use a specified amount of memory tocache the read andor write operations The solution reports the amount of memory configured byeach controller for the read and write operations

The Write Flush Byte Rate represents the rate in MBsec at which data is committed to the disk(ie physically written) This value is to be compared with the Write Byte Rate of the disk array

55Monitoring the Efficiency of the CachingMechanism

BMC Performance Manager Express for EMC Disk Arrays

Version 2001

Comparing W rite Flush Byte Rate w ith W rite Byte Rate

The Cache Dirty Pages Percentage parameter represents the amount in percentage of the writecache that has been modified by host write operations and not yet flushed to the disks Reaching100 means that write case is too small and cannot handle the flow of write operations

Checking the Cache Dirty Pages Percentage

Reclaiming Space of Unmapped(Unused) LUNsOver time as servers connected to a SAN get decommissioned administrators find an increasingnumber of unmapped LUNs or volumes that are no longer used by any server These LUNs whileunused still occupy disk space in the disk array Being able to identify such unmapped LUNs andreclaim the disk space uselessly consumed by these LUNs will help administrators avoid unnecessaryupgrades and extensions of their disk arrays

56Reporting a Disk Space Consumption

BMC Performance Manager Express for EMC Disk Arrays

Version 2001

Reporting a Disk SpaceConsumptionMaking sure that a disk array has enough remaining disk space available is critical for severalreasons

middot SAN administrators want to make sure to be able to provision disk space for new servers whenrequested as quickly as possible

middot The disk array itself may need additional disk space for specific features to work properly likeautomatic snapshots mirroring etc

middot If thin provisioning is used the remaining disk space becomes dramatically critical since theinability to allocate additional space to a LUN when requested by the subscriber host will lead tocatastrophic data loss and corruption

The disk space used is permanently monitored for each storage pool The Subscribed Capacityparameter of the Pool class represents the amount of disk space that has been made available tothe subscriber hosts or in other words the amount of disk space that is seen by the serversconnected to disk array

The Consumed Capacity parameter of the SEN_EMC_STORAGEPOOLS class represents the actualspace usage in the storage pool For thin pools (when thin provisioning is enabled on the disk array)this value is normally lower than the Subscribed Capacity as it is the main purpose of thinprovisioning For traditional pools the Consumed Capacity parameters has the same value as theSubscribed Capacity parameter as the entirety of the subscribed disk space is fully allocated inthe storage pool

The Consumed Capacity Percentage parameter is the most critical one as a storage pool usagenearing 100 means that SAN administrators will not be able to create new LUNs in the storagepool By default no alarm or warning threshold is set on this parameter as the fullness of a storagepool may be a normal situation However you can set alert thresholds on this parameter as it fitsyour needs

57Reporting a Disk Space Consumption

9 Click Next to continue The system displays a summary of your settings click Finish to confirmThe Adapter has been added to the Adapters folder of the Administration Console

Adapter added to the Adapters folder

10 To see the class instances that have been imported by the Adapter expand the Adapters folderright-click the Adapter and select Details

We strongly recommend that you create a specific adapter for each PM you need to integrate into BMCProactiveNet to enable the update of a single PM independently

Once created and imported the Adapter will be displayed in the Devices folder of the BMCProactiveNet Operations Console

Managing Baselines and KeyPerformance IndicatorsIn order to facilitate the detection of abnormalities on your monitored environment BMCProactiveNet calculates baselines per parameter (metrics or attributes) based on values collectedover a specified period of time to determine a normal operating range When the collected values forthese parameters are out of range an alert is triggered

Some parameters are identified by default as Key Performance Indicators and therefore automaticallyincluded in the base lining calculation

42Managing Baselines and Key PerformanceIndicators

BMC Performance Manager Express for EMC Disk Arrays

Version 2001

Managing baselines

The baseline is the expected normal operating range for a metric or attribute of a monitor

The baseline is calculated by collecting the values for a monitorrsquos attributes and metrics over aspecified time period and establishing a low baseline value (consisting of the 10th percentile of all thevalues for a given time period) and a high baseline value (consisting of the 90th percentile of all thevalues for a given time period) taking a weighted average of these values over time A higher weightis given to the latest data being factored into the baseline average The accuracy of the baselineimproves over time

Requirements for baseline generation

For baselines to be generated for an attribute that abnormality threshold means that the thresholdexists and is not suppressed Additionally if the Key Performance Indicator (KPI) mode is active only those attributes that have anactive abnormality threshold and are also KPI attributes will have baselines generated for them

Absolute thresholds (with outside baseline) or signature thresholds do not satisfy these requirements

Managing Key Performance Indicators

The KPI attribute of a parameter can be activated or deactivated manually through the BMCProactiveNet Administration Console In this PM some parameters or attributes have beendesignated as important indicators of performance (KPIs) We do not recommend that these defaultsettings are modified

However advanced users may activate or deactivate KPIs from the BMC ProactiveNet AdministrationConsole

To add or remove Key Performance Indicator (KPI) attributes for amonitor type

1 In the Administration Console from the menu bar choose Tools gt KPI AdministrationThe KPI Administration dialog box is displayed

2 From the Monitor Type list choose the monitor type for which you want to add or remove KPIattributes A list of attributes for the selected monitor type is displayed

3 In the KPI column for the attributes that you want to add or remove as Key PerformanceIndicators

middot select the KPI check box to add the corresponding attribute as a KPI

middot deselect the KPI check box to remove the corresponding attribute from the KPIs for thatmonitor type

For complete and detailed information on this procedure please refer to the BMC ProactiveNet documentation availablefrom BMC Web site

BMC Performance Manager Express for EMC Disk Arrays

Version 2001

BMC Performance Manager Express for EMC Disk Arrays monitors all of the performance metrics andusage statistics of your EMC disk arrays such as file disk space usage storage controller utilizationIOs on the diskscontrollersvolumes etc It continuously monitors the activity of each array and isalso able to build reports on past utilization statistics

To setup a complete monitoring of the array we strongly recommend you to also use BMCPerformance Manager Express for Hardware that covers all the physical aspect of the EMC diskarrays (status of the disks ports temperature power supplies power consumption etc)

This chapter explains how to use each monitoring tool ie a separate application class within theBMC Performance Manager Express for EMC Disk Arrays by Sentry Software solution

BMC Performance Manager Express for EMC Disk Arrays is a Performance Manager specifically designedfor BMC Portal consequently it uses the same common features and procedures of BMCreg Portal Thisdocument assumes that the user knows how to use the Portal and therefore explains procedures onlyrelated to BMC Performance Manager Express for EMC Disk Arrays and not on how to add ElementsElement Profiles etc Please refer to the BMC Portal documentation for details on how to use the Portal

Checking Available Spare Disks

To avoid any loss of critical data it is essential for a disk array to always maintain a pool of sparedisks that can replace the faulty disk when a disk failure occurs A disk array without any left sparedisk will not be able to keep the level of data safety and performance in case of a disk failure

The Spare Disk Count parameter of the SEN_EMC_ARRAY class reports the number of spare disksavailable for each disk array monitored with the solution By default a warning is triggered when nospare disk is available (Spare Disk Count is set to zero)

Verifying the Number of Available Spare Disks in Your EMC Disk Arrays

49Checking Available Spare Disks

BMC Performance Manager Express for EMC Disk Arrays

Version 2001

1 Select an element group in the tree view (the main Infrastructure group for example)

2 Click the Reports tab Create a report for the last 24 hours bottom 50 values of the Array|Spare Disk Count parameter of the EMC Disk Arrays application class for the BMC PerformanceManager Express for EMC Disk Arrays by Sentry Software solution

Report ndash Available Spare Disks

Detecting OversubscriptionSituations (Thin Provisioning)We call an oversubscription situation when

1 The storage pool is configured for thin provisioning (ldquothin storage poolrdquo)

2 The storage pool is oversubscribed ie the total disk space visible to the hosts (subscribers) isgreater than its actual capacity (this situation is normal for a thin pool since it is its very purpose)

3 The storage pool actual consumed capacity is nearing 100

Such situation is highly critical because the inability to allocate additional space to a LUN whenrequested by the subscriber host will lead to catastrophic data loss and corruption

When the conditions described above are met the solution sets the Oversubscription Situationparameter to 1 automatically raising a warning By default the warning for OversubscriptionSituation is issued when the Consumed Capacity Percentage parameter goes above 100 Thisthreshold can be configured in the input properties of the solution

50Detecting Oversubscription Situations (ThinProvisioning)

BMC Performance Manager Express for EMC Disk Arrays

Version 2001

Configuring Oversubscription Threshold

1 Click the EMC Disk Arrays icon and then the Configure tab

2 Edit the Oversubscription Situation Threshold () property to the appropriate value Whenthe Oversubscription Situation parameter triggers a warning it is highly recommended thatthe SAN administrators add capacity to the storage pool as soon as possible

Diagnosing Slow LUNs

If a system administrator complains that his servers are experiencing slow IOs performance and thatit is caused by the SAN you may want to verify the actual response time of the LUNs the server isrelying on

The Response Time parameter of the SEN_EMC_VOLUME class represents the average time it tookto complete the read and write operations on the LUN during the collection interval Typically theaverage response time is below 10 milliseconds You may also want to compare this value to theresponse time of the other LUNs to see whether one server is really getting worse IO performancethan another

Volume - Response Time Parameter

If the response time is low you will need to check the amount of data that is written and read onthis LUN The bad performance may simply be due to an abnormally large amount of data to processOtherwise the problem is maybe between the disk array and the server in the fiber links

51Enabling the Debug Mode

BMC Performance Manager Express for EMC Disk Arrays

Version 2001

Enabling the Debug Mode

By default BMC Performance Manager Express for EMC Disk Arrays sends only the most criticalinformation warning and error messages to the Application Collection Status parameter Mostoften this information is accurate enough to ensure that BMC Performance Manager Express for EMCDisk Arrays is functioning properly If you encounter an issue and wish to report it to customersupport you will be asked to enable the Debug Mode and provide the debug output to the supportteam

1 In the Configure tab gt under Tasks click Elements

2 Select the Element whose debug output you require and click Edit

3 Scroll down to Application Classes gt click the Application class for which you want toenable the debug mode gt click Edit

4 Select Yes from the drop-down Debug Mode list gt SaveBy default BMC Performance Manager Express for EMC Disk Arrays sends its debug output to RSM_HOMERSM(xx)serverrsmlogsen_debuglog

5 Wait for 15 minutes and then disable the debug mode by selecting No

6 Send the debug file to the support team

Pay attention to the file size -the debug output of BMC Performance Manager Express for EMC Disk Arrays could bevery large if enabled for several days

Identifying the Hosts that canAccess a LUNIn most SAN configurations each LUN belongs to a storage group whose host members are the onlyones authorized to access the LUN This is called LUN masking For each LUN the solution displaysits WWN the storage group to which it belongs to as well as the hosts member of this group Inmost cases identifying the storage group of a LUN is sufficient to recognize the server that is usingit

52Identifying LUNs not Owned by their Normal(Default) Storage Processor

BMC Performance Manager Express for EMC Disk Arrays

Version 2001

Identifying LUNs not Owned bytheir Normal (Default) StorageProcessorThe Owning Storage Processor parameter reports the name of the controller that handles IOsfor each LUN If a LUN is not currently handled by its normal (default) storage processors the nameof the default controller will be indicated as SP_B (default SP_A)rdquo

To identify LUNs that are not owned by their normal storage processor you simply need to list the Volume objects where the Owning Storage Processor parameter contains the string Default

Identifying Most Busy LUNs

To identify the LUNs that generate the most traffic on the disk array use the Read Byte Rate andWrite Byte Rate parameters of the LUN class that expose the data throughput for each LUN Usethese parameters to report on the total data traffic (per hour or per day) on each LUN in GB

To make sure that traffic is displayed cumulatively per hour select a time window of at least 12 hours in the graphwindow select at least 7 days to visualize per day cumulative data

1 In the Status tab click the Volume for which you need to check the LUNs activity then expandthe LUNs object to display the ReadWrite Byte Rate parameters

53Identifying Most Busy LUNs

54Identifying Most Busy LUNs

BMC Performance Manager Express for EMC Disk Arrays

Version 2001

View ing a LUNs ReadW rite Byte Rate as a graph

Identifying a Storage Processor(Controllers) OverloadTo visualize the activity of a controller in an EMC disk array use the Processor Utilizationparameter of the SEN_EMC_CONTROLLER class A warning is issued when the processor utilizationgoes too high which means that the controllers cannot keep up with the load on the disk array It isthen important to identify what is overloading the controllers

The Response Time parameter of the SEN_EMC_CONTROLLER class represents the average time ittook the controller to process the read and write requests of the hosts The higher the ResponseTime goes the slower IOs the servers will get By default the solution triggers a warning when thecontroller takes more than 10 milliseconds on average to complete the IO requests and an alarmwhen the response time reaches 100 milliseconds

Monitoring the Efficiency of theCaching MechanismEach controller in an EMC disk array can be configured to use a specified amount of memory tocache the read andor write operations The solution reports the amount of memory configured byeach controller for the read and write operations

The Write Flush Byte Rate represents the rate in MBsec at which data is committed to the disk(ie physically written) This value is to be compared with the Write Byte Rate of the disk array

55Monitoring the Efficiency of the CachingMechanism

BMC Performance Manager Express for EMC Disk Arrays

Version 2001

Comparing W rite Flush Byte Rate w ith W rite Byte Rate

The Cache Dirty Pages Percentage parameter represents the amount in percentage of the writecache that has been modified by host write operations and not yet flushed to the disks Reaching100 means that write case is too small and cannot handle the flow of write operations

Checking the Cache Dirty Pages Percentage

Reclaiming Space of Unmapped(Unused) LUNsOver time as servers connected to a SAN get decommissioned administrators find an increasingnumber of unmapped LUNs or volumes that are no longer used by any server These LUNs whileunused still occupy disk space in the disk array Being able to identify such unmapped LUNs andreclaim the disk space uselessly consumed by these LUNs will help administrators avoid unnecessaryupgrades and extensions of their disk arrays

56Reporting a Disk Space Consumption

BMC Performance Manager Express for EMC Disk Arrays

Version 2001

Reporting a Disk SpaceConsumptionMaking sure that a disk array has enough remaining disk space available is critical for severalreasons

middot SAN administrators want to make sure to be able to provision disk space for new servers whenrequested as quickly as possible

middot The disk array itself may need additional disk space for specific features to work properly likeautomatic snapshots mirroring etc

middot If thin provisioning is used the remaining disk space becomes dramatically critical since theinability to allocate additional space to a LUN when requested by the subscriber host will lead tocatastrophic data loss and corruption

The disk space used is permanently monitored for each storage pool The Subscribed Capacityparameter of the Pool class represents the amount of disk space that has been made available tothe subscriber hosts or in other words the amount of disk space that is seen by the serversconnected to disk array

The Consumed Capacity parameter of the SEN_EMC_STORAGEPOOLS class represents the actualspace usage in the storage pool For thin pools (when thin provisioning is enabled on the disk array)this value is normally lower than the Subscribed Capacity as it is the main purpose of thinprovisioning For traditional pools the Consumed Capacity parameters has the same value as theSubscribed Capacity parameter as the entirety of the subscribed disk space is fully allocated inthe storage pool

The Consumed Capacity Percentage parameter is the most critical one as a storage pool usagenearing 100 means that SAN administrators will not be able to create new LUNs in the storagepool By default no alarm or warning threshold is set on this parameter as the fullness of a storagepool may be a normal situation However you can set alert thresholds on this parameter as it fitsyour needs

57Reporting a Disk Space Consumption

42Managing Baselines and Key PerformanceIndicators

BMC Performance Manager Express for EMC Disk Arrays

Version 2001

Managing baselines

The baseline is the expected normal operating range for a metric or attribute of a monitor

The baseline is calculated by collecting the values for a monitorrsquos attributes and metrics over aspecified time period and establishing a low baseline value (consisting of the 10th percentile of all thevalues for a given time period) and a high baseline value (consisting of the 90th percentile of all thevalues for a given time period) taking a weighted average of these values over time A higher weightis given to the latest data being factored into the baseline average The accuracy of the baselineimproves over time

Requirements for baseline generation

For baselines to be generated for an attribute that abnormality threshold means that the thresholdexists and is not suppressed Additionally if the Key Performance Indicator (KPI) mode is active only those attributes that have anactive abnormality threshold and are also KPI attributes will have baselines generated for them

Absolute thresholds (with outside baseline) or signature thresholds do not satisfy these requirements

Managing Key Performance Indicators

The KPI attribute of a parameter can be activated or deactivated manually through the BMCProactiveNet Administration Console In this PM some parameters or attributes have beendesignated as important indicators of performance (KPIs) We do not recommend that these defaultsettings are modified

However advanced users may activate or deactivate KPIs from the BMC ProactiveNet AdministrationConsole

To add or remove Key Performance Indicator (KPI) attributes for amonitor type

1 In the Administration Console from the menu bar choose Tools gt KPI AdministrationThe KPI Administration dialog box is displayed

2 From the Monitor Type list choose the monitor type for which you want to add or remove KPIattributes A list of attributes for the selected monitor type is displayed

3 In the KPI column for the attributes that you want to add or remove as Key PerformanceIndicators

middot select the KPI check box to add the corresponding attribute as a KPI

middot deselect the KPI check box to remove the corresponding attribute from the KPIs for thatmonitor type

For complete and detailed information on this procedure please refer to the BMC ProactiveNet documentation availablefrom BMC Web site

BMC Performance Manager Express for EMC Disk Arrays

Version 2001

BMC Performance Manager Express for EMC Disk Arrays monitors all of the performance metrics andusage statistics of your EMC disk arrays such as file disk space usage storage controller utilizationIOs on the diskscontrollersvolumes etc It continuously monitors the activity of each array and isalso able to build reports on past utilization statistics

To setup a complete monitoring of the array we strongly recommend you to also use BMCPerformance Manager Express for Hardware that covers all the physical aspect of the EMC diskarrays (status of the disks ports temperature power supplies power consumption etc)

This chapter explains how to use each monitoring tool ie a separate application class within theBMC Performance Manager Express for EMC Disk Arrays by Sentry Software solution

BMC Performance Manager Express for EMC Disk Arrays is a Performance Manager specifically designedfor BMC Portal consequently it uses the same common features and procedures of BMCreg Portal Thisdocument assumes that the user knows how to use the Portal and therefore explains procedures onlyrelated to BMC Performance Manager Express for EMC Disk Arrays and not on how to add ElementsElement Profiles etc Please refer to the BMC Portal documentation for details on how to use the Portal

Checking Available Spare Disks

To avoid any loss of critical data it is essential for a disk array to always maintain a pool of sparedisks that can replace the faulty disk when a disk failure occurs A disk array without any left sparedisk will not be able to keep the level of data safety and performance in case of a disk failure

The Spare Disk Count parameter of the SEN_EMC_ARRAY class reports the number of spare disksavailable for each disk array monitored with the solution By default a warning is triggered when nospare disk is available (Spare Disk Count is set to zero)

Verifying the Number of Available Spare Disks in Your EMC Disk Arrays

49Checking Available Spare Disks

BMC Performance Manager Express for EMC Disk Arrays

Version 2001

1 Select an element group in the tree view (the main Infrastructure group for example)

2 Click the Reports tab Create a report for the last 24 hours bottom 50 values of the Array|Spare Disk Count parameter of the EMC Disk Arrays application class for the BMC PerformanceManager Express for EMC Disk Arrays by Sentry Software solution

Report ndash Available Spare Disks

Detecting OversubscriptionSituations (Thin Provisioning)We call an oversubscription situation when

1 The storage pool is configured for thin provisioning (ldquothin storage poolrdquo)

2 The storage pool is oversubscribed ie the total disk space visible to the hosts (subscribers) isgreater than its actual capacity (this situation is normal for a thin pool since it is its very purpose)

3 The storage pool actual consumed capacity is nearing 100

Such situation is highly critical because the inability to allocate additional space to a LUN whenrequested by the subscriber host will lead to catastrophic data loss and corruption

When the conditions described above are met the solution sets the Oversubscription Situationparameter to 1 automatically raising a warning By default the warning for OversubscriptionSituation is issued when the Consumed Capacity Percentage parameter goes above 100 Thisthreshold can be configured in the input properties of the solution

50Detecting Oversubscription Situations (ThinProvisioning)

BMC Performance Manager Express for EMC Disk Arrays

Version 2001

Configuring Oversubscription Threshold

1 Click the EMC Disk Arrays icon and then the Configure tab

2 Edit the Oversubscription Situation Threshold () property to the appropriate value Whenthe Oversubscription Situation parameter triggers a warning it is highly recommended thatthe SAN administrators add capacity to the storage pool as soon as possible

Diagnosing Slow LUNs

If a system administrator complains that his servers are experiencing slow IOs performance and thatit is caused by the SAN you may want to verify the actual response time of the LUNs the server isrelying on

The Response Time parameter of the SEN_EMC_VOLUME class represents the average time it tookto complete the read and write operations on the LUN during the collection interval Typically theaverage response time is below 10 milliseconds You may also want to compare this value to theresponse time of the other LUNs to see whether one server is really getting worse IO performancethan another

Volume - Response Time Parameter

If the response time is low you will need to check the amount of data that is written and read onthis LUN The bad performance may simply be due to an abnormally large amount of data to processOtherwise the problem is maybe between the disk array and the server in the fiber links

51Enabling the Debug Mode

BMC Performance Manager Express for EMC Disk Arrays

Version 2001

Enabling the Debug Mode

By default BMC Performance Manager Express for EMC Disk Arrays sends only the most criticalinformation warning and error messages to the Application Collection Status parameter Mostoften this information is accurate enough to ensure that BMC Performance Manager Express for EMCDisk Arrays is functioning properly If you encounter an issue and wish to report it to customersupport you will be asked to enable the Debug Mode and provide the debug output to the supportteam

1 In the Configure tab gt under Tasks click Elements

2 Select the Element whose debug output you require and click Edit

3 Scroll down to Application Classes gt click the Application class for which you want toenable the debug mode gt click Edit

4 Select Yes from the drop-down Debug Mode list gt SaveBy default BMC Performance Manager Express for EMC Disk Arrays sends its debug output to RSM_HOMERSM(xx)serverrsmlogsen_debuglog

5 Wait for 15 minutes and then disable the debug mode by selecting No

6 Send the debug file to the support team

Pay attention to the file size -the debug output of BMC Performance Manager Express for EMC Disk Arrays could bevery large if enabled for several days

Identifying the Hosts that canAccess a LUNIn most SAN configurations each LUN belongs to a storage group whose host members are the onlyones authorized to access the LUN This is called LUN masking For each LUN the solution displaysits WWN the storage group to which it belongs to as well as the hosts member of this group Inmost cases identifying the storage group of a LUN is sufficient to recognize the server that is usingit

52Identifying LUNs not Owned by their Normal(Default) Storage Processor

BMC Performance Manager Express for EMC Disk Arrays

Version 2001

Identifying LUNs not Owned bytheir Normal (Default) StorageProcessorThe Owning Storage Processor parameter reports the name of the controller that handles IOsfor each LUN If a LUN is not currently handled by its normal (default) storage processors the nameof the default controller will be indicated as SP_B (default SP_A)rdquo

To identify LUNs that are not owned by their normal storage processor you simply need to list the Volume objects where the Owning Storage Processor parameter contains the string Default

Identifying Most Busy LUNs

To identify the LUNs that generate the most traffic on the disk array use the Read Byte Rate andWrite Byte Rate parameters of the LUN class that expose the data throughput for each LUN Usethese parameters to report on the total data traffic (per hour or per day) on each LUN in GB

To make sure that traffic is displayed cumulatively per hour select a time window of at least 12 hours in the graphwindow select at least 7 days to visualize per day cumulative data

1 In the Status tab click the Volume for which you need to check the LUNs activity then expandthe LUNs object to display the ReadWrite Byte Rate parameters

53Identifying Most Busy LUNs

BMC Performance Manager Express for EMC Disk Arrays

Version 2001

Selecting a LUNs ReadW rite Byte Rate Parameter

2 Click the History icon to automatically display a graph that shows the ReadWrite Byte Ratevalues collected for a selected parameter during the previous six hours You can customize thechart and table to show parameter history for different time periods

54Identifying Most Busy LUNs

BMC Performance Manager Express for EMC Disk Arrays

Version 2001

View ing a LUNs ReadW rite Byte Rate as a graph

Identifying a Storage Processor(Controllers) OverloadTo visualize the activity of a controller in an EMC disk array use the Processor Utilizationparameter of the SEN_EMC_CONTROLLER class A warning is issued when the processor utilizationgoes too high which means that the controllers cannot keep up with the load on the disk array It isthen important to identify what is overloading the controllers

The Response Time parameter of the SEN_EMC_CONTROLLER class represents the average time ittook the controller to process the read and write requests of the hosts The higher the ResponseTime goes the slower IOs the servers will get By default the solution triggers a warning when thecontroller takes more than 10 milliseconds on average to complete the IO requests and an alarmwhen the response time reaches 100 milliseconds

Monitoring the Efficiency of theCaching MechanismEach controller in an EMC disk array can be configured to use a specified amount of memory tocache the read andor write operations The solution reports the amount of memory configured byeach controller for the read and write operations

The Write Flush Byte Rate represents the rate in MBsec at which data is committed to the disk(ie physically written) This value is to be compared with the Write Byte Rate of the disk array

55Monitoring the Efficiency of the CachingMechanism

BMC Performance Manager Express for EMC Disk Arrays

Version 2001

Comparing W rite Flush Byte Rate w ith W rite Byte Rate

The Cache Dirty Pages Percentage parameter represents the amount in percentage of the writecache that has been modified by host write operations and not yet flushed to the disks Reaching100 means that write case is too small and cannot handle the flow of write operations

Checking the Cache Dirty Pages Percentage

Reclaiming Space of Unmapped(Unused) LUNsOver time as servers connected to a SAN get decommissioned administrators find an increasingnumber of unmapped LUNs or volumes that are no longer used by any server These LUNs whileunused still occupy disk space in the disk array Being able to identify such unmapped LUNs andreclaim the disk space uselessly consumed by these LUNs will help administrators avoid unnecessaryupgrades and extensions of their disk arrays

56Reporting a Disk Space Consumption

BMC Performance Manager Express for EMC Disk Arrays

Version 2001

Reporting a Disk SpaceConsumptionMaking sure that a disk array has enough remaining disk space available is critical for severalreasons

middot SAN administrators want to make sure to be able to provision disk space for new servers whenrequested as quickly as possible

middot The disk array itself may need additional disk space for specific features to work properly likeautomatic snapshots mirroring etc

middot If thin provisioning is used the remaining disk space becomes dramatically critical since theinability to allocate additional space to a LUN when requested by the subscriber host will lead tocatastrophic data loss and corruption

The disk space used is permanently monitored for each storage pool The Subscribed Capacityparameter of the Pool class represents the amount of disk space that has been made available tothe subscriber hosts or in other words the amount of disk space that is seen by the serversconnected to disk array

The Consumed Capacity parameter of the SEN_EMC_STORAGEPOOLS class represents the actualspace usage in the storage pool For thin pools (when thin provisioning is enabled on the disk array)this value is normally lower than the Subscribed Capacity as it is the main purpose of thinprovisioning For traditional pools the Consumed Capacity parameters has the same value as theSubscribed Capacity parameter as the entirety of the subscribed disk space is fully allocated inthe storage pool

The Consumed Capacity Percentage parameter is the most critical one as a storage pool usagenearing 100 means that SAN administrators will not be able to create new LUNs in the storagepool By default no alarm or warning threshold is set on this parameter as the fullness of a storagepool may be a normal situation However you can set alert thresholds on this parameter as it fitsyour needs

57Reporting a Disk Space Consumption

BMC Performance Manager Express for EMC Disk Arrays

Version 2001

Verifying the Available Disk Space in the Storage Pool of your EMC DiskArrays

1 In the Configure tab select an element group in the tree view (the main ldquoInfrastructurerdquogroup for example)

2 Click on the Reports tab

3 Create a report for the last 24 hours top 50 values of the Array|Storage Pools|Disk Group|Storage Pool|Consumed Capacity Percentage parameter of the EMC Disk Arraysapplication class for the BMC Performance Manager Express for EMC Disk Arrays by SentrySoftware solution

Report ndash Disk Space Consumption

Reporting the Total Traffic on anHourly or Daily BasisBMC Performance Manager Express for EMC Disk Arrays not only monitors the traffic and activity ofthe disk array controllers LUNs and physical disks in MBsec but also in GB per hour or per day Theexact amount of data that was read or written to the disk array LUN or physical disk is calculated foreach hour of the day and each day of the week

Each data rate parameter in MBsec is accompanied by a non-rate one in GB These parameters areldquocumulativerdquo their instantaneous value has no meaning and they need to be visualized in a longperiod of time (instead of Read Byte Rate or Write Byte Rate)

58Reporting the Total Traffic on an Hourly orDaily Basis

Setting thresholds

Whenever relevant BMC Performance Manager Express for EMC Disk Arrays automatically setsthresholds for parameters If you prefer a more fault-tolerant monitoring you can modify thethresholds of each parameter through the Configure tab gt Edit Thresholds

It is strongly recommended to wait for all the storage objects to be discovered before setting threshold values to avoidhaving to enter thresholds for each occurrence of the application class

To modify the parameter thresholds of several storage objects of an element

60Setting thresholds

BMC Performance Manager Express for EMC Disk Arrays

Version 2001

1 In the Configure tab click on the Storage (ltplatformgt) or the instance icon gt Edit

Thresholds Properties and Credentials

Any modification to the thresholds or any other properties of elements created using the Element

Profile mode is to be done using the Element Profile route or by clicking Override Profile

2 Uncheck the Warning and Alarm boxes for all the parameters for which you want to disablethe alert conditions

4 Click Save

5 The Success changes have been saved message indicates that the modifications have beenregistered

Alerts are displayed by the parameter whose thresholds are modified

Viewing the Overall Activity of aDisk ArrayIn order to visualize the activity of a disk array use the Read Byte Rate and Write Byte Rate ofthe SEN_EMC_ARRAY class These parameters represent the overall traffic in megabytes per secondfor each monitored array or more precisely each EMC disk array that is exposed through the EMCSMI-S Provider (see the EMC_SMI-S_Provider section of the Installation Guide for more informationabout the EMC SMI-S Provider)

62Viewing the Overall Activity of a Disk Array

BMC Performance Manager Express for EMC Disk Arrays

Viewing a Disk Array Activity

1 Click the Status tab in Portal

2 Click the array icon in the tree view to visualize its current activity

BMC Performance Manager Express for EMC Disk Arrays

Version 2001

BMC Performance Manager Express for EMC Disk Arrays monitors all of the performance metrics andusage statistics of your EMC disk arrays such as file disk space usage storage controller utilizationIOs on the diskscontrollersvolumes etc It continuously monitors the activity of each array and isalso able to build reports on past utilization statistics

To setup a complete monitoring of the array we strongly recommend you to also use BMCPerformance Manager Express for Hardware that covers all the physical aspect of the EMC diskarrays (status of the disks ports temperature power supplies power consumption etc)

This chapter explains how to use each monitoring tool ie a separate application class within theBMC Performance Manager Express for EMC Disk Arrays by Sentry Software solution

BMC Performance Manager Express for EMC Disk Arrays is a Performance Manager specifically designedfor BMC Portal consequently it uses the same common features and procedures of BMCreg Portal Thisdocument assumes that the user knows how to use the Portal and therefore explains procedures onlyrelated to BMC Performance Manager Express for EMC Disk Arrays and not on how to add ElementsElement Profiles etc Please refer to the BMC Portal documentation for details on how to use the Portal

Checking Available Spare Disks

To avoid any loss of critical data it is essential for a disk array to always maintain a pool of sparedisks that can replace the faulty disk when a disk failure occurs A disk array without any left sparedisk will not be able to keep the level of data safety and performance in case of a disk failure

The Spare Disk Count parameter of the SEN_EMC_ARRAY class reports the number of spare disksavailable for each disk array monitored with the solution By default a warning is triggered when nospare disk is available (Spare Disk Count is set to zero)

Verifying the Number of Available Spare Disks in Your EMC Disk Arrays

49Checking Available Spare Disks

BMC Performance Manager Express for EMC Disk Arrays

Version 2001

1 Select an element group in the tree view (the main Infrastructure group for example)

2 Click the Reports tab Create a report for the last 24 hours bottom 50 values of the Array|Spare Disk Count parameter of the EMC Disk Arrays application class for the BMC PerformanceManager Express for EMC Disk Arrays by Sentry Software solution

Report ndash Available Spare Disks

Detecting OversubscriptionSituations (Thin Provisioning)We call an oversubscription situation when

1 The storage pool is configured for thin provisioning (ldquothin storage poolrdquo)

2 The storage pool is oversubscribed ie the total disk space visible to the hosts (subscribers) isgreater than its actual capacity (this situation is normal for a thin pool since it is its very purpose)

3 The storage pool actual consumed capacity is nearing 100

Such situation is highly critical because the inability to allocate additional space to a LUN whenrequested by the subscriber host will lead to catastrophic data loss and corruption

When the conditions described above are met the solution sets the Oversubscription Situationparameter to 1 automatically raising a warning By default the warning for OversubscriptionSituation is issued when the Consumed Capacity Percentage parameter goes above 100 Thisthreshold can be configured in the input properties of the solution

50Detecting Oversubscription Situations (ThinProvisioning)

BMC Performance Manager Express for EMC Disk Arrays

Version 2001

Configuring Oversubscription Threshold

1 Click the EMC Disk Arrays icon and then the Configure tab

2 Edit the Oversubscription Situation Threshold () property to the appropriate value Whenthe Oversubscription Situation parameter triggers a warning it is highly recommended thatthe SAN administrators add capacity to the storage pool as soon as possible

Diagnosing Slow LUNs

If a system administrator complains that his servers are experiencing slow IOs performance and thatit is caused by the SAN you may want to verify the actual response time of the LUNs the server isrelying on

The Response Time parameter of the SEN_EMC_VOLUME class represents the average time it tookto complete the read and write operations on the LUN during the collection interval Typically theaverage response time is below 10 milliseconds You may also want to compare this value to theresponse time of the other LUNs to see whether one server is really getting worse IO performancethan another

Volume - Response Time Parameter

If the response time is low you will need to check the amount of data that is written and read onthis LUN The bad performance may simply be due to an abnormally large amount of data to processOtherwise the problem is maybe between the disk array and the server in the fiber links

51Enabling the Debug Mode

BMC Performance Manager Express for EMC Disk Arrays

Version 2001

Enabling the Debug Mode

By default BMC Performance Manager Express for EMC Disk Arrays sends only the most criticalinformation warning and error messages to the Application Collection Status parameter Mostoften this information is accurate enough to ensure that BMC Performance Manager Express for EMCDisk Arrays is functioning properly If you encounter an issue and wish to report it to customersupport you will be asked to enable the Debug Mode and provide the debug output to the supportteam

1 In the Configure tab gt under Tasks click Elements

2 Select the Element whose debug output you require and click Edit

3 Scroll down to Application Classes gt click the Application class for which you want toenable the debug mode gt click Edit

4 Select Yes from the drop-down Debug Mode list gt SaveBy default BMC Performance Manager Express for EMC Disk Arrays sends its debug output to RSM_HOMERSM(xx)serverrsmlogsen_debuglog

5 Wait for 15 minutes and then disable the debug mode by selecting No

6 Send the debug file to the support team

Pay attention to the file size -the debug output of BMC Performance Manager Express for EMC Disk Arrays could bevery large if enabled for several days

Identifying the Hosts that canAccess a LUNIn most SAN configurations each LUN belongs to a storage group whose host members are the onlyones authorized to access the LUN This is called LUN masking For each LUN the solution displaysits WWN the storage group to which it belongs to as well as the hosts member of this group Inmost cases identifying the storage group of a LUN is sufficient to recognize the server that is usingit

52Identifying LUNs not Owned by their Normal(Default) Storage Processor

BMC Performance Manager Express for EMC Disk Arrays

Version 2001

Identifying LUNs not Owned bytheir Normal (Default) StorageProcessorThe Owning Storage Processor parameter reports the name of the controller that handles IOsfor each LUN If a LUN is not currently handled by its normal (default) storage processors the nameof the default controller will be indicated as SP_B (default SP_A)rdquo

To identify LUNs that are not owned by their normal storage processor you simply need to list the Volume objects where the Owning Storage Processor parameter contains the string Default

Identifying Most Busy LUNs

To identify the LUNs that generate the most traffic on the disk array use the Read Byte Rate andWrite Byte Rate parameters of the LUN class that expose the data throughput for each LUN Usethese parameters to report on the total data traffic (per hour or per day) on each LUN in GB

To make sure that traffic is displayed cumulatively per hour select a time window of at least 12 hours in the graphwindow select at least 7 days to visualize per day cumulative data

1 In the Status tab click the Volume for which you need to check the LUNs activity then expandthe LUNs object to display the ReadWrite Byte Rate parameters

53Identifying Most Busy LUNs

2 Click the History icon to automatically display a graph that shows the ReadWrite Byte Ratevalues collected for a selected parameter during the previous six hours You can customize thechart and table to show parameter history for different time periods

54Identifying Most Busy LUNs

BMC Performance Manager Express for EMC Disk Arrays

Version 2001

View ing a LUNs ReadW rite Byte Rate as a graph

Identifying a Storage Processor(Controllers) OverloadTo visualize the activity of a controller in an EMC disk array use the Processor Utilizationparameter of the SEN_EMC_CONTROLLER class A warning is issued when the processor utilizationgoes too high which means that the controllers cannot keep up with the load on the disk array It isthen important to identify what is overloading the controllers

The Response Time parameter of the SEN_EMC_CONTROLLER class represents the average time ittook the controller to process the read and write requests of the hosts The higher the ResponseTime goes the slower IOs the servers will get By default the solution triggers a warning when thecontroller takes more than 10 milliseconds on average to complete the IO requests and an alarmwhen the response time reaches 100 milliseconds

Monitoring the Efficiency of theCaching MechanismEach controller in an EMC disk array can be configured to use a specified amount of memory tocache the read andor write operations The solution reports the amount of memory configured byeach controller for the read and write operations

The Write Flush Byte Rate represents the rate in MBsec at which data is committed to the disk(ie physically written) This value is to be compared with the Write Byte Rate of the disk array

55Monitoring the Efficiency of the CachingMechanism

BMC Performance Manager Express for EMC Disk Arrays

Version 2001

Comparing W rite Flush Byte Rate w ith W rite Byte Rate

The Cache Dirty Pages Percentage parameter represents the amount in percentage of the writecache that has been modified by host write operations and not yet flushed to the disks Reaching100 means that write case is too small and cannot handle the flow of write operations

Checking the Cache Dirty Pages Percentage

Reclaiming Space of Unmapped(Unused) LUNsOver time as servers connected to a SAN get decommissioned administrators find an increasingnumber of unmapped LUNs or volumes that are no longer used by any server These LUNs whileunused still occupy disk space in the disk array Being able to identify such unmapped LUNs andreclaim the disk space uselessly consumed by these LUNs will help administrators avoid unnecessaryupgrades and extensions of their disk arrays

56Reporting a Disk Space Consumption

BMC Performance Manager Express for EMC Disk Arrays

Version 2001

Reporting a Disk SpaceConsumptionMaking sure that a disk array has enough remaining disk space available is critical for severalreasons

middot SAN administrators want to make sure to be able to provision disk space for new servers whenrequested as quickly as possible

middot The disk array itself may need additional disk space for specific features to work properly likeautomatic snapshots mirroring etc

middot If thin provisioning is used the remaining disk space becomes dramatically critical since theinability to allocate additional space to a LUN when requested by the subscriber host will lead tocatastrophic data loss and corruption

The disk space used is permanently monitored for each storage pool The Subscribed Capacityparameter of the Pool class represents the amount of disk space that has been made available tothe subscriber hosts or in other words the amount of disk space that is seen by the serversconnected to disk array

The Consumed Capacity parameter of the SEN_EMC_STORAGEPOOLS class represents the actualspace usage in the storage pool For thin pools (when thin provisioning is enabled on the disk array)this value is normally lower than the Subscribed Capacity as it is the main purpose of thinprovisioning For traditional pools the Consumed Capacity parameters has the same value as theSubscribed Capacity parameter as the entirety of the subscribed disk space is fully allocated inthe storage pool

The Consumed Capacity Percentage parameter is the most critical one as a storage pool usagenearing 100 means that SAN administrators will not be able to create new LUNs in the storagepool By default no alarm or warning threshold is set on this parameter as the fullness of a storagepool may be a normal situation However you can set alert thresholds on this parameter as it fitsyour needs

57Reporting a Disk Space Consumption

BMC Performance Manager Express for EMC Disk Arrays

Version 2001

BMC Performance Manager Express for EMC Disk Arrays monitors all of the performance metrics andusage statistics of your EMC disk arrays such as file disk space usage storage controller utilizationIOs on the diskscontrollersvolumes etc It continuously monitors the activity of each array and isalso able to build reports on past utilization statistics

To setup a complete monitoring of the array we strongly recommend you to also use BMCPerformance Manager Express for Hardware that covers all the physical aspect of the EMC diskarrays (status of the disks ports temperature power supplies power consumption etc)

This chapter explains how to use each monitoring tool ie a separate application class within theBMC Performance Manager Express for EMC Disk Arrays by Sentry Software solution

BMC Performance Manager Express for EMC Disk Arrays is a Performance Manager specifically designedfor BMC Portal consequently it uses the same common features and procedures of BMCreg Portal Thisdocument assumes that the user knows how to use the Portal and therefore explains procedures onlyrelated to BMC Performance Manager Express for EMC Disk Arrays and not on how to add ElementsElement Profiles etc Please refer to the BMC Portal documentation for details on how to use the Portal

Checking Available Spare Disks

To avoid any loss of critical data it is essential for a disk array to always maintain a pool of sparedisks that can replace the faulty disk when a disk failure occurs A disk array without any left sparedisk will not be able to keep the level of data safety and performance in case of a disk failure

The Spare Disk Count parameter of the SEN_EMC_ARRAY class reports the number of spare disksavailable for each disk array monitored with the solution By default a warning is triggered when nospare disk is available (Spare Disk Count is set to zero)

Verifying the Number of Available Spare Disks in Your EMC Disk Arrays

49Checking Available Spare Disks

BMC Performance Manager Express for EMC Disk Arrays

Version 2001

1 Select an element group in the tree view (the main Infrastructure group for example)

2 Click the Reports tab Create a report for the last 24 hours bottom 50 values of the Array|Spare Disk Count parameter of the EMC Disk Arrays application class for the BMC PerformanceManager Express for EMC Disk Arrays by Sentry Software solution

Report ndash Available Spare Disks

Detecting OversubscriptionSituations (Thin Provisioning)We call an oversubscription situation when

1 The storage pool is configured for thin provisioning (ldquothin storage poolrdquo)

2 The storage pool is oversubscribed ie the total disk space visible to the hosts (subscribers) isgreater than its actual capacity (this situation is normal for a thin pool since it is its very purpose)

3 The storage pool actual consumed capacity is nearing 100

Such situation is highly critical because the inability to allocate additional space to a LUN whenrequested by the subscriber host will lead to catastrophic data loss and corruption

When the conditions described above are met the solution sets the Oversubscription Situationparameter to 1 automatically raising a warning By default the warning for OversubscriptionSituation is issued when the Consumed Capacity Percentage parameter goes above 100 Thisthreshold can be configured in the input properties of the solution

50Detecting Oversubscription Situations (ThinProvisioning)

BMC Performance Manager Express for EMC Disk Arrays

Version 2001

Configuring Oversubscription Threshold

1 Click the EMC Disk Arrays icon and then the Configure tab

2 Edit the Oversubscription Situation Threshold () property to the appropriate value Whenthe Oversubscription Situation parameter triggers a warning it is highly recommended thatthe SAN administrators add capacity to the storage pool as soon as possible

Diagnosing Slow LUNs

If a system administrator complains that his servers are experiencing slow IOs performance and thatit is caused by the SAN you may want to verify the actual response time of the LUNs the server isrelying on

The Response Time parameter of the SEN_EMC_VOLUME class represents the average time it tookto complete the read and write operations on the LUN during the collection interval Typically theaverage response time is below 10 milliseconds You may also want to compare this value to theresponse time of the other LUNs to see whether one server is really getting worse IO performancethan another

Volume - Response Time Parameter

If the response time is low you will need to check the amount of data that is written and read onthis LUN The bad performance may simply be due to an abnormally large amount of data to processOtherwise the problem is maybe between the disk array and the server in the fiber links

51Enabling the Debug Mode

BMC Performance Manager Express for EMC Disk Arrays

Version 2001

Enabling the Debug Mode

By default BMC Performance Manager Express for EMC Disk Arrays sends only the most criticalinformation warning and error messages to the Application Collection Status parameter Mostoften this information is accurate enough to ensure that BMC Performance Manager Express for EMCDisk Arrays is functioning properly If you encounter an issue and wish to report it to customersupport you will be asked to enable the Debug Mode and provide the debug output to the supportteam

1 In the Configure tab gt under Tasks click Elements

2 Select the Element whose debug output you require and click Edit

3 Scroll down to Application Classes gt click the Application class for which you want toenable the debug mode gt click Edit

4 Select Yes from the drop-down Debug Mode list gt SaveBy default BMC Performance Manager Express for EMC Disk Arrays sends its debug output to RSM_HOMERSM(xx)serverrsmlogsen_debuglog

5 Wait for 15 minutes and then disable the debug mode by selecting No

6 Send the debug file to the support team

Pay attention to the file size -the debug output of BMC Performance Manager Express for EMC Disk Arrays could bevery large if enabled for several days

Identifying the Hosts that canAccess a LUNIn most SAN configurations each LUN belongs to a storage group whose host members are the onlyones authorized to access the LUN This is called LUN masking For each LUN the solution displaysits WWN the storage group to which it belongs to as well as the hosts member of this group Inmost cases identifying the storage group of a LUN is sufficient to recognize the server that is usingit

52Identifying LUNs not Owned by their Normal(Default) Storage Processor

BMC Performance Manager Express for EMC Disk Arrays

Version 2001

Identifying LUNs not Owned bytheir Normal (Default) StorageProcessorThe Owning Storage Processor parameter reports the name of the controller that handles IOsfor each LUN If a LUN is not currently handled by its normal (default) storage processors the nameof the default controller will be indicated as SP_B (default SP_A)rdquo

To identify LUNs that are not owned by their normal storage processor you simply need to list the Volume objects where the Owning Storage Processor parameter contains the string Default

Identifying Most Busy LUNs

To identify the LUNs that generate the most traffic on the disk array use the Read Byte Rate andWrite Byte Rate parameters of the LUN class that expose the data throughput for each LUN Usethese parameters to report on the total data traffic (per hour or per day) on each LUN in GB

To make sure that traffic is displayed cumulatively per hour select a time window of at least 12 hours in the graphwindow select at least 7 days to visualize per day cumulative data

1 In the Status tab click the Volume for which you need to check the LUNs activity then expandthe LUNs object to display the ReadWrite Byte Rate parameters

53Identifying Most Busy LUNs

BMC Performance Manager Express for EMC Disk Arrays

Version 2001

Selecting a LUNs ReadW rite Byte Rate Parameter

2 Click the History icon to automatically display a graph that shows the ReadWrite Byte Ratevalues collected for a selected parameter during the previous six hours You can customize thechart and table to show parameter history for different time periods

54Identifying Most Busy LUNs

BMC Performance Manager Express for EMC Disk Arrays

Version 2001

View ing a LUNs ReadW rite Byte Rate as a graph

Identifying a Storage Processor(Controllers) OverloadTo visualize the activity of a controller in an EMC disk array use the Processor Utilizationparameter of the SEN_EMC_CONTROLLER class A warning is issued when the processor utilizationgoes too high which means that the controllers cannot keep up with the load on the disk array It isthen important to identify what is overloading the controllers

The Response Time parameter of the SEN_EMC_CONTROLLER class represents the average time ittook the controller to process the read and write requests of the hosts The higher the ResponseTime goes the slower IOs the servers will get By default the solution triggers a warning when thecontroller takes more than 10 milliseconds on average to complete the IO requests and an alarmwhen the response time reaches 100 milliseconds

Monitoring the Efficiency of theCaching MechanismEach controller in an EMC disk array can be configured to use a specified amount of memory tocache the read andor write operations The solution reports the amount of memory configured byeach controller for the read and write operations

The Write Flush Byte Rate represents the rate in MBsec at which data is committed to the disk(ie physically written) This value is to be compared with the Write Byte Rate of the disk array

55Monitoring the Efficiency of the CachingMechanism

BMC Performance Manager Express for EMC Disk Arrays

Version 2001

Comparing W rite Flush Byte Rate w ith W rite Byte Rate

The Cache Dirty Pages Percentage parameter represents the amount in percentage of the writecache that has been modified by host write operations and not yet flushed to the disks Reaching100 means that write case is too small and cannot handle the flow of write operations

Checking the Cache Dirty Pages Percentage

Reclaiming Space of Unmapped(Unused) LUNsOver time as servers connected to a SAN get decommissioned administrators find an increasingnumber of unmapped LUNs or volumes that are no longer used by any server These LUNs whileunused still occupy disk space in the disk array Being able to identify such unmapped LUNs andreclaim the disk space uselessly consumed by these LUNs will help administrators avoid unnecessaryupgrades and extensions of their disk arrays

56Reporting a Disk Space Consumption

BMC Performance Manager Express for EMC Disk Arrays

Version 2001

Reporting a Disk SpaceConsumptionMaking sure that a disk array has enough remaining disk space available is critical for severalreasons

middot SAN administrators want to make sure to be able to provision disk space for new servers whenrequested as quickly as possible

middot The disk array itself may need additional disk space for specific features to work properly likeautomatic snapshots mirroring etc

middot If thin provisioning is used the remaining disk space becomes dramatically critical since theinability to allocate additional space to a LUN when requested by the subscriber host will lead tocatastrophic data loss and corruption

The disk space used is permanently monitored for each storage pool The Subscribed Capacityparameter of the Pool class represents the amount of disk space that has been made available tothe subscriber hosts or in other words the amount of disk space that is seen by the serversconnected to disk array

The Consumed Capacity parameter of the SEN_EMC_STORAGEPOOLS class represents the actualspace usage in the storage pool For thin pools (when thin provisioning is enabled on the disk array)this value is normally lower than the Subscribed Capacity as it is the main purpose of thinprovisioning For traditional pools the Consumed Capacity parameters has the same value as theSubscribed Capacity parameter as the entirety of the subscribed disk space is fully allocated inthe storage pool

The Consumed Capacity Percentage parameter is the most critical one as a storage pool usagenearing 100 means that SAN administrators will not be able to create new LUNs in the storagepool By default no alarm or warning threshold is set on this parameter as the fullness of a storagepool may be a normal situation However you can set alert thresholds on this parameter as it fitsyour needs

57Reporting a Disk Space Consumption

BMC Performance Manager Express for EMC Disk Arrays

Version 2001

BMC Performance Manager Express for EMC Disk Arrays

Version 2001

BMC Performance Manager Express for EMC Disk Arrays monitors all of the performance metrics andusage statistics of your EMC disk arrays such as file disk space usage storage controller utilizationIOs on the diskscontrollersvolumes etc It continuously monitors the activity of each array and isalso able to build reports on past utilization statistics

To setup a complete monitoring of the array we strongly recommend you to also use BMCPerformance Manager Express for Hardware that covers all the physical aspect of the EMC diskarrays (status of the disks ports temperature power supplies power consumption etc)

This chapter explains how to use each monitoring tool ie a separate application class within theBMC Performance Manager Express for EMC Disk Arrays by Sentry Software solution

BMC Performance Manager Express for EMC Disk Arrays is a Performance Manager specifically designedfor BMC Portal consequently it uses the same common features and procedures of BMCreg Portal Thisdocument assumes that the user knows how to use the Portal and therefore explains procedures onlyrelated to BMC Performance Manager Express for EMC Disk Arrays and not on how to add ElementsElement Profiles etc Please refer to the BMC Portal documentation for details on how to use the Portal

Checking Available Spare Disks

To avoid any loss of critical data it is essential for a disk array to always maintain a pool of sparedisks that can replace the faulty disk when a disk failure occurs A disk array without any left sparedisk will not be able to keep the level of data safety and performance in case of a disk failure

The Spare Disk Count parameter of the SEN_EMC_ARRAY class reports the number of spare disksavailable for each disk array monitored with the solution By default a warning is triggered when nospare disk is available (Spare Disk Count is set to zero)

Verifying the Number of Available Spare Disks in Your EMC Disk Arrays

49Checking Available Spare Disks

BMC Performance Manager Express for EMC Disk Arrays

Version 2001

1 Select an element group in the tree view (the main Infrastructure group for example)

2 Click the Reports tab Create a report for the last 24 hours bottom 50 values of the Array|Spare Disk Count parameter of the EMC Disk Arrays application class for the BMC PerformanceManager Express for EMC Disk Arrays by Sentry Software solution

Detecting OversubscriptionSituations (Thin Provisioning)We call an oversubscription situation when

1 The storage pool is configured for thin provisioning (ldquothin storage poolrdquo)

2 The storage pool is oversubscribed ie the total disk space visible to the hosts (subscribers) isgreater than its actual capacity (this situation is normal for a thin pool since it is its very purpose)

3 The storage pool actual consumed capacity is nearing 100

Such situation is highly critical because the inability to allocate additional space to a LUN whenrequested by the subscriber host will lead to catastrophic data loss and corruption

When the conditions described above are met the solution sets the Oversubscription Situationparameter to 1 automatically raising a warning By default the warning for OversubscriptionSituation is issued when the Consumed Capacity Percentage parameter goes above 100 Thisthreshold can be configured in the input properties of the solution

50Detecting Oversubscription Situations (ThinProvisioning)

BMC Performance Manager Express for EMC Disk Arrays

Version 2001

Configuring Oversubscription Threshold

1 Click the EMC Disk Arrays icon and then the Configure tab

2 Edit the Oversubscription Situation Threshold () property to the appropriate value Whenthe Oversubscription Situation parameter triggers a warning it is highly recommended thatthe SAN administrators add capacity to the storage pool as soon as possible

Diagnosing Slow LUNs

If a system administrator complains that his servers are experiencing slow IOs performance and thatit is caused by the SAN you may want to verify the actual response time of the LUNs the server isrelying on

The Response Time parameter of the SEN_EMC_VOLUME class represents the average time it tookto complete the read and write operations on the LUN during the collection interval Typically theaverage response time is below 10 milliseconds You may also want to compare this value to theresponse time of the other LUNs to see whether one server is really getting worse IO performancethan another

Volume - Response Time Parameter

If the response time is low you will need to check the amount of data that is written and read onthis LUN The bad performance may simply be due to an abnormally large amount of data to processOtherwise the problem is maybe between the disk array and the server in the fiber links

51Enabling the Debug Mode

BMC Performance Manager Express for EMC Disk Arrays

Version 2001

Enabling the Debug Mode

By default BMC Performance Manager Express for EMC Disk Arrays sends only the most criticalinformation warning and error messages to the Application Collection Status parameter Mostoften this information is accurate enough to ensure that BMC Performance Manager Express for EMCDisk Arrays is functioning properly If you encounter an issue and wish to report it to customersupport you will be asked to enable the Debug Mode and provide the debug output to the supportteam

1 In the Configure tab gt under Tasks click Elements

2 Select the Element whose debug output you require and click Edit

3 Scroll down to Application Classes gt click the Application class for which you want toenable the debug mode gt click Edit

4 Select Yes from the drop-down Debug Mode list gt SaveBy default BMC Performance Manager Express for EMC Disk Arrays sends its debug output to RSM_HOMERSM(xx)serverrsmlogsen_debuglog

5 Wait for 15 minutes and then disable the debug mode by selecting No

6 Send the debug file to the support team

Pay attention to the file size -the debug output of BMC Performance Manager Express for EMC Disk Arrays could bevery large if enabled for several days

Identifying the Hosts that canAccess a LUNIn most SAN configurations each LUN belongs to a storage group whose host members are the onlyones authorized to access the LUN This is called LUN masking For each LUN the solution displaysits WWN the storage group to which it belongs to as well as the hosts member of this group Inmost cases identifying the storage group of a LUN is sufficient to recognize the server that is usingit

52Identifying LUNs not Owned by their Normal(Default) Storage Processor

BMC Performance Manager Express for EMC Disk Arrays

Version 2001

Identifying LUNs not Owned bytheir Normal (Default) StorageProcessorThe Owning Storage Processor parameter reports the name of the controller that handles IOsfor each LUN If a LUN is not currently handled by its normal (default) storage processors the nameof the default controller will be indicated as SP_B (default SP_A)rdquo

To identify LUNs that are not owned by their normal storage processor you simply need to list the Volume objects where the Owning Storage Processor parameter contains the string Default

Identifying Most Busy LUNs

To identify the LUNs that generate the most traffic on the disk array use the Read Byte Rate andWrite Byte Rate parameters of the LUN class that expose the data throughput for each LUN Usethese parameters to report on the total data traffic (per hour or per day) on each LUN in GB

To make sure that traffic is displayed cumulatively per hour select a time window of at least 12 hours in the graphwindow select at least 7 days to visualize per day cumulative data

1 In the Status tab click the Volume for which you need to check the LUNs activity then expandthe LUNs object to display the ReadWrite Byte Rate parameters

53Identifying Most Busy LUNs

BMC Performance Manager Express for EMC Disk Arrays

Version 2001

Selecting a LUNs ReadW rite Byte Rate Parameter

2 Click the History icon to automatically display a graph that shows the ReadWrite Byte Ratevalues collected for a selected parameter during the previous six hours You can customize thechart and table to show parameter history for different time periods

54Identifying Most Busy LUNs

BMC Performance Manager Express for EMC Disk Arrays

Version 2001

View ing a LUNs ReadW rite Byte Rate as a graph

Identifying a Storage Processor(Controllers) OverloadTo visualize the activity of a controller in an EMC disk array use the Processor Utilizationparameter of the SEN_EMC_CONTROLLER class A warning is issued when the processor utilizationgoes too high which means that the controllers cannot keep up with the load on the disk array It isthen important to identify what is overloading the controllers

The Response Time parameter of the SEN_EMC_CONTROLLER class represents the average time ittook the controller to process the read and write requests of the hosts The higher the ResponseTime goes the slower IOs the servers will get By default the solution triggers a warning when thecontroller takes more than 10 milliseconds on average to complete the IO requests and an alarmwhen the response time reaches 100 milliseconds

Monitoring the Efficiency of theCaching MechanismEach controller in an EMC disk array can be configured to use a specified amount of memory tocache the read andor write operations The solution reports the amount of memory configured byeach controller for the read and write operations

The Write Flush Byte Rate represents the rate in MBsec at which data is committed to the disk(ie physically written) This value is to be compared with the Write Byte Rate of the disk array

55Monitoring the Efficiency of the CachingMechanism

BMC Performance Manager Express for EMC Disk Arrays

Version 2001

Comparing W rite Flush Byte Rate w ith W rite Byte Rate

The Cache Dirty Pages Percentage parameter represents the amount in percentage of the writecache that has been modified by host write operations and not yet flushed to the disks Reaching100 means that write case is too small and cannot handle the flow of write operations

Checking the Cache Dirty Pages Percentage

Reclaiming Space of Unmapped(Unused) LUNsOver time as servers connected to a SAN get decommissioned administrators find an increasingnumber of unmapped LUNs or volumes that are no longer used by any server These LUNs whileunused still occupy disk space in the disk array Being able to identify such unmapped LUNs andreclaim the disk space uselessly consumed by these LUNs will help administrators avoid unnecessaryupgrades and extensions of their disk arrays

56Reporting a Disk Space Consumption

BMC Performance Manager Express for EMC Disk Arrays

Version 2001

Reporting a Disk SpaceConsumptionMaking sure that a disk array has enough remaining disk space available is critical for severalreasons

middot SAN administrators want to make sure to be able to provision disk space for new servers whenrequested as quickly as possible

middot The disk array itself may need additional disk space for specific features to work properly likeautomatic snapshots mirroring etc

middot If thin provisioning is used the remaining disk space becomes dramatically critical since theinability to allocate additional space to a LUN when requested by the subscriber host will lead tocatastrophic data loss and corruption

The disk space used is permanently monitored for each storage pool The Subscribed Capacityparameter of the Pool class represents the amount of disk space that has been made available tothe subscriber hosts or in other words the amount of disk space that is seen by the serversconnected to disk array

The Consumed Capacity parameter of the SEN_EMC_STORAGEPOOLS class represents the actualspace usage in the storage pool For thin pools (when thin provisioning is enabled on the disk array)this value is normally lower than the Subscribed Capacity as it is the main purpose of thinprovisioning For traditional pools the Consumed Capacity parameters has the same value as theSubscribed Capacity parameter as the entirety of the subscribed disk space is fully allocated inthe storage pool

The Consumed Capacity Percentage parameter is the most critical one as a storage pool usagenearing 100 means that SAN administrators will not be able to create new LUNs in the storagepool By default no alarm or warning threshold is set on this parameter as the fullness of a storagepool may be a normal situation However you can set alert thresholds on this parameter as it fitsyour needs

57Reporting a Disk Space Consumption

BMC Performance Manager Express for EMC Disk Arrays

Version 2001

Verifying the Available Disk Space in the Storage Pool of your EMC DiskArrays

1 In the Configure tab select an element group in the tree view (the main ldquoInfrastructurerdquogroup for example)

2 Click on the Reports tab

3 Create a report for the last 24 hours top 50 values of the Array|Storage Pools|Disk Group|Storage Pool|Consumed Capacity Percentage parameter of the EMC Disk Arraysapplication class for the BMC Performance Manager Express for EMC Disk Arrays by SentrySoftware solution

Report ndash Disk Space Consumption

Reporting the Total Traffic on anHourly or Daily BasisBMC Performance Manager Express for EMC Disk Arrays not only monitors the traffic and activity ofthe disk array controllers LUNs and physical disks in MBsec but also in GB per hour or per day Theexact amount of data that was read or written to the disk array LUN or physical disk is calculated foreach hour of the day and each day of the week

Each data rate parameter in MBsec is accompanied by a non-rate one in GB These parameters areldquocumulativerdquo their instantaneous value has no meaning and they need to be visualized in a longperiod of time (instead of Read Byte Rate or Write Byte Rate)

58Reporting the Total Traffic on an Hourly orDaily Basis

Setting thresholds

Whenever relevant BMC Performance Manager Express for EMC Disk Arrays automatically setsthresholds for parameters If you prefer a more fault-tolerant monitoring you can modify thethresholds of each parameter through the Configure tab gt Edit Thresholds

It is strongly recommended to wait for all the storage objects to be discovered before setting threshold values to avoidhaving to enter thresholds for each occurrence of the application class

To modify the parameter thresholds of several storage objects of an element

60Setting thresholds

BMC Performance Manager Express for EMC Disk Arrays

Version 2001

1 In the Configure tab click on the Storage (ltplatformgt) or the instance icon gt Edit

Thresholds Properties and Credentials

Any modification to the thresholds or any other properties of elements created using the Element

Profile mode is to be done using the Element Profile route or by clicking Override Profile

2 Uncheck the Warning and Alarm boxes for all the parameters for which you want to disablethe alert conditions

3 Check the Warning and Alarm boxes for all the parameters for which you want to enable thealert conditions You will then have to manually enter the threshold values and check the Activebox In the example below a Warning will be triggered if Status is greater than 1 an alarm willbe triggered when greater than 2

Modifying threshold values

4 Click Save

5 The Success changes have been saved message indicates that the modifications have beenregistered

Alerts are displayed by the parameter whose thresholds are modified

Viewing the Overall Activity of aDisk ArrayIn order to visualize the activity of a disk array use the Read Byte Rate and Write Byte Rate ofthe SEN_EMC_ARRAY class These parameters represent the overall traffic in megabytes per secondfor each monitored array or more precisely each EMC disk array that is exposed through the EMCSMI-S Provider (see the EMC_SMI-S_Provider section of the Installation Guide for more informationabout the EMC SMI-S Provider)

62Viewing the Overall Activity of a Disk Array

BMC Performance Manager Express for EMC Disk Arrays

Viewing a Disk Array Activity

1 Click the Status tab in Portal

2 Click the array icon in the tree view to visualize its current activity

BMC Performance Manager Express for EMC Disk Arrays monitors all of the performance metrics andusage statistics of your EMC disk arrays such as file disk space usage storage controller utilizationIOs on the diskscontrollersvolumes etc It continuously monitors the activity of each array and isalso able to build reports on past utilization statistics

To setup a complete monitoring of the array we strongly recommend you to also use BMCPerformance Manager Express for Hardware that covers all the physical aspect of the EMC diskarrays (status of the disks ports temperature power supplies power consumption etc)

This chapter explains how to use each monitoring tool ie a separate application class within theBMC Performance Manager Express for EMC Disk Arrays by Sentry Software solution

BMC Performance Manager Express for EMC Disk Arrays is a Performance Manager specifically designedfor BMC Portal consequently it uses the same common features and procedures of BMCreg Portal Thisdocument assumes that the user knows how to use the Portal and therefore explains procedures onlyrelated to BMC Performance Manager Express for EMC Disk Arrays and not on how to add ElementsElement Profiles etc Please refer to the BMC Portal documentation for details on how to use the Portal

Checking Available Spare Disks

To avoid any loss of critical data it is essential for a disk array to always maintain a pool of sparedisks that can replace the faulty disk when a disk failure occurs A disk array without any left sparedisk will not be able to keep the level of data safety and performance in case of a disk failure

The Spare Disk Count parameter of the SEN_EMC_ARRAY class reports the number of spare disksavailable for each disk array monitored with the solution By default a warning is triggered when nospare disk is available (Spare Disk Count is set to zero)

Verifying the Number of Available Spare Disks in Your EMC Disk Arrays

49Checking Available Spare Disks

BMC Performance Manager Express for EMC Disk Arrays

Version 2001

1 Select an element group in the tree view (the main Infrastructure group for example)

2 Click the Reports tab Create a report for the last 24 hours bottom 50 values of the Array|Spare Disk Count parameter of the EMC Disk Arrays application class for the BMC PerformanceManager Express for EMC Disk Arrays by Sentry Software solution

Report ndash Available Spare Disks

Detecting OversubscriptionSituations (Thin Provisioning)We call an oversubscription situation when

1 The storage pool is configured for thin provisioning (ldquothin storage poolrdquo)

2 The storage pool is oversubscribed ie the total disk space visible to the hosts (subscribers) isgreater than its actual capacity (this situation is normal for a thin pool since it is its very purpose)

3 The storage pool actual consumed capacity is nearing 100

Such situation is highly critical because the inability to allocate additional space to a LUN whenrequested by the subscriber host will lead to catastrophic data loss and corruption

When the conditions described above are met the solution sets the Oversubscription Situationparameter to 1 automatically raising a warning By default the warning for OversubscriptionSituation is issued when the Consumed Capacity Percentage parameter goes above 100 Thisthreshold can be configured in the input properties of the solution

50Detecting Oversubscription Situations (ThinProvisioning)

BMC Performance Manager Express for EMC Disk Arrays

Version 2001

Configuring Oversubscription Threshold

1 Click the EMC Disk Arrays icon and then the Configure tab

2 Edit the Oversubscription Situation Threshold () property to the appropriate value Whenthe Oversubscription Situation parameter triggers a warning it is highly recommended thatthe SAN administrators add capacity to the storage pool as soon as possible

Diagnosing Slow LUNs

If a system administrator complains that his servers are experiencing slow IOs performance and thatit is caused by the SAN you may want to verify the actual response time of the LUNs the server isrelying on

The Response Time parameter of the SEN_EMC_VOLUME class represents the average time it tookto complete the read and write operations on the LUN during the collection interval Typically theaverage response time is below 10 milliseconds You may also want to compare this value to theresponse time of the other LUNs to see whether one server is really getting worse IO performancethan another

Volume - Response Time Parameter

If the response time is low you will need to check the amount of data that is written and read onthis LUN The bad performance may simply be due to an abnormally large amount of data to processOtherwise the problem is maybe between the disk array and the server in the fiber links

51Enabling the Debug Mode

BMC Performance Manager Express for EMC Disk Arrays

Version 2001

Enabling the Debug Mode

By default BMC Performance Manager Express for EMC Disk Arrays sends only the most criticalinformation warning and error messages to the Application Collection Status parameter Mostoften this information is accurate enough to ensure that BMC Performance Manager Express for EMCDisk Arrays is functioning properly If you encounter an issue and wish to report it to customersupport you will be asked to enable the Debug Mode and provide the debug output to the supportteam

1 In the Configure tab gt under Tasks click Elements

2 Select the Element whose debug output you require and click Edit

3 Scroll down to Application Classes gt click the Application class for which you want toenable the debug mode gt click Edit

4 Select Yes from the drop-down Debug Mode list gt SaveBy default BMC Performance Manager Express for EMC Disk Arrays sends its debug output to RSM_HOMERSM(xx)serverrsmlogsen_debuglog

5 Wait for 15 minutes and then disable the debug mode by selecting No

6 Send the debug file to the support team

Pay attention to the file size -the debug output of BMC Performance Manager Express for EMC Disk Arrays could bevery large if enabled for several days

Identifying the Hosts that canAccess a LUNIn most SAN configurations each LUN belongs to a storage group whose host members are the onlyones authorized to access the LUN This is called LUN masking For each LUN the solution displaysits WWN the storage group to which it belongs to as well as the hosts member of this group Inmost cases identifying the storage group of a LUN is sufficient to recognize the server that is usingit

52Identifying LUNs not Owned by their Normal(Default) Storage Processor

BMC Performance Manager Express for EMC Disk Arrays

Version 2001

Identifying LUNs not Owned bytheir Normal (Default) StorageProcessorThe Owning Storage Processor parameter reports the name of the controller that handles IOsfor each LUN If a LUN is not currently handled by its normal (default) storage processors the nameof the default controller will be indicated as SP_B (default SP_A)rdquo

To identify LUNs that are not owned by their normal storage processor you simply need to list the Volume objects where the Owning Storage Processor parameter contains the string Default

Identifying Most Busy LUNs

To identify the LUNs that generate the most traffic on the disk array use the Read Byte Rate andWrite Byte Rate parameters of the LUN class that expose the data throughput for each LUN Usethese parameters to report on the total data traffic (per hour or per day) on each LUN in GB

To make sure that traffic is displayed cumulatively per hour select a time window of at least 12 hours in the graphwindow select at least 7 days to visualize per day cumulative data

1 In the Status tab click the Volume for which you need to check the LUNs activity then expandthe LUNs object to display the ReadWrite Byte Rate parameters

53Identifying Most Busy LUNs

View ing a LUNs ReadW rite Byte Rate as a graph

Identifying a Storage Processor(Controllers) OverloadTo visualize the activity of a controller in an EMC disk array use the Processor Utilizationparameter of the SEN_EMC_CONTROLLER class A warning is issued when the processor utilizationgoes too high which means that the controllers cannot keep up with the load on the disk array It isthen important to identify what is overloading the controllers

The Response Time parameter of the SEN_EMC_CONTROLLER class represents the average time ittook the controller to process the read and write requests of the hosts The higher the ResponseTime goes the slower IOs the servers will get By default the solution triggers a warning when thecontroller takes more than 10 milliseconds on average to complete the IO requests and an alarmwhen the response time reaches 100 milliseconds

Monitoring the Efficiency of theCaching MechanismEach controller in an EMC disk array can be configured to use a specified amount of memory tocache the read andor write operations The solution reports the amount of memory configured byeach controller for the read and write operations

The Write Flush Byte Rate represents the rate in MBsec at which data is committed to the disk(ie physically written) This value is to be compared with the Write Byte Rate of the disk array

55Monitoring the Efficiency of the CachingMechanism

BMC Performance Manager Express for EMC Disk Arrays

Version 2001

Comparing W rite Flush Byte Rate w ith W rite Byte Rate

The Cache Dirty Pages Percentage parameter represents the amount in percentage of the writecache that has been modified by host write operations and not yet flushed to the disks Reaching100 means that write case is too small and cannot handle the flow of write operations

Checking the Cache Dirty Pages Percentage

Reclaiming Space of Unmapped(Unused) LUNsOver time as servers connected to a SAN get decommissioned administrators find an increasingnumber of unmapped LUNs or volumes that are no longer used by any server These LUNs whileunused still occupy disk space in the disk array Being able to identify such unmapped LUNs andreclaim the disk space uselessly consumed by these LUNs will help administrators avoid unnecessaryupgrades and extensions of their disk arrays

56Reporting a Disk Space Consumption

BMC Performance Manager Express for EMC Disk Arrays

Version 2001

Reporting a Disk SpaceConsumptionMaking sure that a disk array has enough remaining disk space available is critical for severalreasons

middot SAN administrators want to make sure to be able to provision disk space for new servers whenrequested as quickly as possible

middot The disk array itself may need additional disk space for specific features to work properly likeautomatic snapshots mirroring etc

middot If thin provisioning is used the remaining disk space becomes dramatically critical since theinability to allocate additional space to a LUN when requested by the subscriber host will lead tocatastrophic data loss and corruption

The disk space used is permanently monitored for each storage pool The Subscribed Capacityparameter of the Pool class represents the amount of disk space that has been made available tothe subscriber hosts or in other words the amount of disk space that is seen by the serversconnected to disk array

The Consumed Capacity parameter of the SEN_EMC_STORAGEPOOLS class represents the actualspace usage in the storage pool For thin pools (when thin provisioning is enabled on the disk array)this value is normally lower than the Subscribed Capacity as it is the main purpose of thinprovisioning For traditional pools the Consumed Capacity parameters has the same value as theSubscribed Capacity parameter as the entirety of the subscribed disk space is fully allocated inthe storage pool

The Consumed Capacity Percentage parameter is the most critical one as a storage pool usagenearing 100 means that SAN administrators will not be able to create new LUNs in the storagepool By default no alarm or warning threshold is set on this parameter as the fullness of a storagepool may be a normal situation However you can set alert thresholds on this parameter as it fitsyour needs

57Reporting a Disk Space Consumption

BMC Performance Manager Express for EMC Disk Arrays

Version 2001

BMC Performance Manager Express for EMC Disk Arrays monitors all of the performance metrics andusage statistics of your EMC disk arrays such as file disk space usage storage controller utilizationIOs on the diskscontrollersvolumes etc It continuously monitors the activity of each array and isalso able to build reports on past utilization statistics

To setup a complete monitoring of the array we strongly recommend you to also use BMCPerformance Manager Express for Hardware that covers all the physical aspect of the EMC diskarrays (status of the disks ports temperature power supplies power consumption etc)

This chapter explains how to use each monitoring tool ie a separate application class within theBMC Performance Manager Express for EMC Disk Arrays by Sentry Software solution

BMC Performance Manager Express for EMC Disk Arrays is a Performance Manager specifically designedfor BMC Portal consequently it uses the same common features and procedures of BMCreg Portal Thisdocument assumes that the user knows how to use the Portal and therefore explains procedures onlyrelated to BMC Performance Manager Express for EMC Disk Arrays and not on how to add ElementsElement Profiles etc Please refer to the BMC Portal documentation for details on how to use the Portal

Checking Available Spare Disks

To avoid any loss of critical data it is essential for a disk array to always maintain a pool of sparedisks that can replace the faulty disk when a disk failure occurs A disk array without any left sparedisk will not be able to keep the level of data safety and performance in case of a disk failure

The Spare Disk Count parameter of the SEN_EMC_ARRAY class reports the number of spare disksavailable for each disk array monitored with the solution By default a warning is triggered when nospare disk is available (Spare Disk Count is set to zero)

Verifying the Number of Available Spare Disks in Your EMC Disk Arrays

49Checking Available Spare Disks

BMC Performance Manager Express for EMC Disk Arrays

Version 2001

1 Select an element group in the tree view (the main Infrastructure group for example)

2 Click the Reports tab Create a report for the last 24 hours bottom 50 values of the Array|Spare Disk Count parameter of the EMC Disk Arrays application class for the BMC PerformanceManager Express for EMC Disk Arrays by Sentry Software solution

Report ndash Available Spare Disks

Detecting OversubscriptionSituations (Thin Provisioning)We call an oversubscription situation when

1 The storage pool is configured for thin provisioning (ldquothin storage poolrdquo)

2 The storage pool is oversubscribed ie the total disk space visible to the hosts (subscribers) isgreater than its actual capacity (this situation is normal for a thin pool since it is its very purpose)

3 The storage pool actual consumed capacity is nearing 100

Such situation is highly critical because the inability to allocate additional space to a LUN whenrequested by the subscriber host will lead to catastrophic data loss and corruption

When the conditions described above are met the solution sets the Oversubscription Situationparameter to 1 automatically raising a warning By default the warning for OversubscriptionSituation is issued when the Consumed Capacity Percentage parameter goes above 100 Thisthreshold can be configured in the input properties of the solution

50Detecting Oversubscription Situations (ThinProvisioning)

BMC Performance Manager Express for EMC Disk Arrays

Version 2001

Configuring Oversubscription Threshold

1 Click the EMC Disk Arrays icon and then the Configure tab

2 Edit the Oversubscription Situation Threshold () property to the appropriate value Whenthe Oversubscription Situation parameter triggers a warning it is highly recommended thatthe SAN administrators add capacity to the storage pool as soon as possible

Diagnosing Slow LUNs

If a system administrator complains that his servers are experiencing slow IOs performance and thatit is caused by the SAN you may want to verify the actual response time of the LUNs the server isrelying on

The Response Time parameter of the SEN_EMC_VOLUME class represents the average time it tookto complete the read and write operations on the LUN during the collection interval Typically theaverage response time is below 10 milliseconds You may also want to compare this value to theresponse time of the other LUNs to see whether one server is really getting worse IO performancethan another

Volume - Response Time Parameter

If the response time is low you will need to check the amount of data that is written and read onthis LUN The bad performance may simply be due to an abnormally large amount of data to processOtherwise the problem is maybe between the disk array and the server in the fiber links

51Enabling the Debug Mode

BMC Performance Manager Express for EMC Disk Arrays

Version 2001

Enabling the Debug Mode

By default BMC Performance Manager Express for EMC Disk Arrays sends only the most criticalinformation warning and error messages to the Application Collection Status parameter Mostoften this information is accurate enough to ensure that BMC Performance Manager Express for EMCDisk Arrays is functioning properly If you encounter an issue and wish to report it to customersupport you will be asked to enable the Debug Mode and provide the debug output to the supportteam

1 In the Configure tab gt under Tasks click Elements

2 Select the Element whose debug output you require and click Edit

3 Scroll down to Application Classes gt click the Application class for which you want toenable the debug mode gt click Edit

4 Select Yes from the drop-down Debug Mode list gt SaveBy default BMC Performance Manager Express for EMC Disk Arrays sends its debug output to RSM_HOMERSM(xx)serverrsmlogsen_debuglog

5 Wait for 15 minutes and then disable the debug mode by selecting No

6 Send the debug file to the support team

Pay attention to the file size -the debug output of BMC Performance Manager Express for EMC Disk Arrays could bevery large if enabled for several days

Identifying the Hosts that canAccess a LUNIn most SAN configurations each LUN belongs to a storage group whose host members are the onlyones authorized to access the LUN This is called LUN masking For each LUN the solution displaysits WWN the storage group to which it belongs to as well as the hosts member of this group Inmost cases identifying the storage group of a LUN is sufficient to recognize the server that is usingit

52Identifying LUNs not Owned by their Normal(Default) Storage Processor

BMC Performance Manager Express for EMC Disk Arrays

Version 2001

Identifying LUNs not Owned bytheir Normal (Default) StorageProcessorThe Owning Storage Processor parameter reports the name of the controller that handles IOsfor each LUN If a LUN is not currently handled by its normal (default) storage processors the nameof the default controller will be indicated as SP_B (default SP_A)rdquo

To identify LUNs that are not owned by their normal storage processor you simply need to list the Volume objects where the Owning Storage Processor parameter contains the string Default

Identifying Most Busy LUNs

To identify the LUNs that generate the most traffic on the disk array use the Read Byte Rate andWrite Byte Rate parameters of the LUN class that expose the data throughput for each LUN Usethese parameters to report on the total data traffic (per hour or per day) on each LUN in GB

To make sure that traffic is displayed cumulatively per hour select a time window of at least 12 hours in the graphwindow select at least 7 days to visualize per day cumulative data

1 In the Status tab click the Volume for which you need to check the LUNs activity then expandthe LUNs object to display the ReadWrite Byte Rate parameters

53Identifying Most Busy LUNs

BMC Performance Manager Express for EMC Disk Arrays

Version 2001

Selecting a LUNs ReadW rite Byte Rate Parameter

2 Click the History icon to automatically display a graph that shows the ReadWrite Byte Ratevalues collected for a selected parameter during the previous six hours You can customize thechart and table to show parameter history for different time periods

54Identifying Most Busy LUNs

BMC Performance Manager Express for EMC Disk Arrays

Version 2001

View ing a LUNs ReadW rite Byte Rate as a graph

Identifying a Storage Processor(Controllers) OverloadTo visualize the activity of a controller in an EMC disk array use the Processor Utilizationparameter of the SEN_EMC_CONTROLLER class A warning is issued when the processor utilizationgoes too high which means that the controllers cannot keep up with the load on the disk array It isthen important to identify what is overloading the controllers

The Response Time parameter of the SEN_EMC_CONTROLLER class represents the average time ittook the controller to process the read and write requests of the hosts The higher the ResponseTime goes the slower IOs the servers will get By default the solution triggers a warning when thecontroller takes more than 10 milliseconds on average to complete the IO requests and an alarmwhen the response time reaches 100 milliseconds

Monitoring the Efficiency of theCaching MechanismEach controller in an EMC disk array can be configured to use a specified amount of memory tocache the read andor write operations The solution reports the amount of memory configured byeach controller for the read and write operations

The Write Flush Byte Rate represents the rate in MBsec at which data is committed to the disk(ie physically written) This value is to be compared with the Write Byte Rate of the disk array

55Monitoring the Efficiency of the CachingMechanism

BMC Performance Manager Express for EMC Disk Arrays

Version 2001

Comparing W rite Flush Byte Rate w ith W rite Byte Rate

The Cache Dirty Pages Percentage parameter represents the amount in percentage of the writecache that has been modified by host write operations and not yet flushed to the disks Reaching100 means that write case is too small and cannot handle the flow of write operations

Checking the Cache Dirty Pages Percentage

Reclaiming Space of Unmapped(Unused) LUNsOver time as servers connected to a SAN get decommissioned administrators find an increasingnumber of unmapped LUNs or volumes that are no longer used by any server These LUNs whileunused still occupy disk space in the disk array Being able to identify such unmapped LUNs andreclaim the disk space uselessly consumed by these LUNs will help administrators avoid unnecessaryupgrades and extensions of their disk arrays

56Reporting a Disk Space Consumption

BMC Performance Manager Express for EMC Disk Arrays

Version 2001

Reporting a Disk SpaceConsumptionMaking sure that a disk array has enough remaining disk space available is critical for severalreasons

middot SAN administrators want to make sure to be able to provision disk space for new servers whenrequested as quickly as possible

middot The disk array itself may need additional disk space for specific features to work properly likeautomatic snapshots mirroring etc

middot If thin provisioning is used the remaining disk space becomes dramatically critical since theinability to allocate additional space to a LUN when requested by the subscriber host will lead tocatastrophic data loss and corruption

The disk space used is permanently monitored for each storage pool The Subscribed Capacityparameter of the Pool class represents the amount of disk space that has been made available tothe subscriber hosts or in other words the amount of disk space that is seen by the serversconnected to disk array

The Consumed Capacity parameter of the SEN_EMC_STORAGEPOOLS class represents the actualspace usage in the storage pool For thin pools (when thin provisioning is enabled on the disk array)this value is normally lower than the Subscribed Capacity as it is the main purpose of thinprovisioning For traditional pools the Consumed Capacity parameters has the same value as theSubscribed Capacity parameter as the entirety of the subscribed disk space is fully allocated inthe storage pool

The Consumed Capacity Percentage parameter is the most critical one as a storage pool usagenearing 100 means that SAN administrators will not be able to create new LUNs in the storagepool By default no alarm or warning threshold is set on this parameter as the fullness of a storagepool may be a normal situation However you can set alert thresholds on this parameter as it fitsyour needs

57Reporting a Disk Space Consumption

BMC Performance Manager Express for EMC Disk Arrays

Version 2001

BMC Performance Manager Express for EMC Disk Arrays monitors all of the performance metrics andusage statistics of your EMC disk arrays such as file disk space usage storage controller utilizationIOs on the diskscontrollersvolumes etc It continuously monitors the activity of each array and isalso able to build reports on past utilization statistics

To setup a complete monitoring of the array we strongly recommend you to also use BMCPerformance Manager Express for Hardware that covers all the physical aspect of the EMC diskarrays (status of the disks ports temperature power supplies power consumption etc)

This chapter explains how to use each monitoring tool ie a separate application class within theBMC Performance Manager Express for EMC Disk Arrays by Sentry Software solution

BMC Performance Manager Express for EMC Disk Arrays is a Performance Manager specifically designedfor BMC Portal consequently it uses the same common features and procedures of BMCreg Portal Thisdocument assumes that the user knows how to use the Portal and therefore explains procedures onlyrelated to BMC Performance Manager Express for EMC Disk Arrays and not on how to add ElementsElement Profiles etc Please refer to the BMC Portal documentation for details on how to use the Portal

Checking Available Spare Disks

To avoid any loss of critical data it is essential for a disk array to always maintain a pool of sparedisks that can replace the faulty disk when a disk failure occurs A disk array without any left sparedisk will not be able to keep the level of data safety and performance in case of a disk failure

The Spare Disk Count parameter of the SEN_EMC_ARRAY class reports the number of spare disksavailable for each disk array monitored with the solution By default a warning is triggered when nospare disk is available (Spare Disk Count is set to zero)

Verifying the Number of Available Spare Disks in Your EMC Disk Arrays

49Checking Available Spare Disks

BMC Performance Manager Express for EMC Disk Arrays

Version 2001

1 Select an element group in the tree view (the main Infrastructure group for example)

2 Click the Reports tab Create a report for the last 24 hours bottom 50 values of the Array|Spare Disk Count parameter of the EMC Disk Arrays application class for the BMC PerformanceManager Express for EMC Disk Arrays by Sentry Software solution

Report ndash Available Spare Disks

Detecting OversubscriptionSituations (Thin Provisioning)We call an oversubscription situation when

1 The storage pool is configured for thin provisioning (ldquothin storage poolrdquo)

2 The storage pool is oversubscribed ie the total disk space visible to the hosts (subscribers) isgreater than its actual capacity (this situation is normal for a thin pool since it is its very purpose)

3 The storage pool actual consumed capacity is nearing 100

Such situation is highly critical because the inability to allocate additional space to a LUN whenrequested by the subscriber host will lead to catastrophic data loss and corruption

When the conditions described above are met the solution sets the Oversubscription Situationparameter to 1 automatically raising a warning By default the warning for OversubscriptionSituation is issued when the Consumed Capacity Percentage parameter goes above 100 Thisthreshold can be configured in the input properties of the solution

50Detecting Oversubscription Situations (ThinProvisioning)

BMC Performance Manager Express for EMC Disk Arrays

Version 2001

Configuring Oversubscription Threshold

1 Click the EMC Disk Arrays icon and then the Configure tab

2 Edit the Oversubscription Situation Threshold () property to the appropriate value Whenthe Oversubscription Situation parameter triggers a warning it is highly recommended thatthe SAN administrators add capacity to the storage pool as soon as possible

Diagnosing Slow LUNs

If a system administrator complains that his servers are experiencing slow IOs performance and thatit is caused by the SAN you may want to verify the actual response time of the LUNs the server isrelying on

The Response Time parameter of the SEN_EMC_VOLUME class represents the average time it tookto complete the read and write operations on the LUN during the collection interval Typically theaverage response time is below 10 milliseconds You may also want to compare this value to theresponse time of the other LUNs to see whether one server is really getting worse IO performancethan another

Volume - Response Time Parameter

If the response time is low you will need to check the amount of data that is written and read onthis LUN The bad performance may simply be due to an abnormally large amount of data to processOtherwise the problem is maybe between the disk array and the server in the fiber links

51Enabling the Debug Mode

BMC Performance Manager Express for EMC Disk Arrays

Version 2001

Enabling the Debug Mode

By default BMC Performance Manager Express for EMC Disk Arrays sends only the most criticalinformation warning and error messages to the Application Collection Status parameter Mostoften this information is accurate enough to ensure that BMC Performance Manager Express for EMCDisk Arrays is functioning properly If you encounter an issue and wish to report it to customersupport you will be asked to enable the Debug Mode and provide the debug output to the supportteam

1 In the Configure tab gt under Tasks click Elements

2 Select the Element whose debug output you require and click Edit

3 Scroll down to Application Classes gt click the Application class for which you want toenable the debug mode gt click Edit

4 Select Yes from the drop-down Debug Mode list gt SaveBy default BMC Performance Manager Express for EMC Disk Arrays sends its debug output to RSM_HOMERSM(xx)serverrsmlogsen_debuglog

5 Wait for 15 minutes and then disable the debug mode by selecting No

6 Send the debug file to the support team

Pay attention to the file size -the debug output of BMC Performance Manager Express for EMC Disk Arrays could bevery large if enabled for several days

Identifying the Hosts that canAccess a LUNIn most SAN configurations each LUN belongs to a storage group whose host members are the onlyones authorized to access the LUN This is called LUN masking For each LUN the solution displaysits WWN the storage group to which it belongs to as well as the hosts member of this group Inmost cases identifying the storage group of a LUN is sufficient to recognize the server that is usingit

52Identifying LUNs not Owned by their Normal(Default) Storage Processor

BMC Performance Manager Express for EMC Disk Arrays

Version 2001

Identifying LUNs not Owned bytheir Normal (Default) StorageProcessorThe Owning Storage Processor parameter reports the name of the controller that handles IOsfor each LUN If a LUN is not currently handled by its normal (default) storage processors the nameof the default controller will be indicated as SP_B (default SP_A)rdquo

To identify LUNs that are not owned by their normal storage processor you simply need to list the Volume objects where the Owning Storage Processor parameter contains the string Default

Identifying Most Busy LUNs

To identify the LUNs that generate the most traffic on the disk array use the Read Byte Rate andWrite Byte Rate parameters of the LUN class that expose the data throughput for each LUN Usethese parameters to report on the total data traffic (per hour or per day) on each LUN in GB

To make sure that traffic is displayed cumulatively per hour select a time window of at least 12 hours in the graphwindow select at least 7 days to visualize per day cumulative data

1 In the Status tab click the Volume for which you need to check the LUNs activity then expandthe LUNs object to display the ReadWrite Byte Rate parameters

53Identifying Most Busy LUNs

BMC Performance Manager Express for EMC Disk Arrays

Version 2001

Selecting a LUNs ReadW rite Byte Rate Parameter

2 Click the History icon to automatically display a graph that shows the ReadWrite Byte Ratevalues collected for a selected parameter during the previous six hours You can customize thechart and table to show parameter history for different time periods

54Identifying Most Busy LUNs

BMC Performance Manager Express for EMC Disk Arrays

Version 2001

View ing a LUNs ReadW rite Byte Rate as a graph

Identifying a Storage Processor(Controllers) OverloadTo visualize the activity of a controller in an EMC disk array use the Processor Utilizationparameter of the SEN_EMC_CONTROLLER class A warning is issued when the processor utilizationgoes too high which means that the controllers cannot keep up with the load on the disk array It isthen important to identify what is overloading the controllers

The Response Time parameter of the SEN_EMC_CONTROLLER class represents the average time ittook the controller to process the read and write requests of the hosts The higher the ResponseTime goes the slower IOs the servers will get By default the solution triggers a warning when thecontroller takes more than 10 milliseconds on average to complete the IO requests and an alarmwhen the response time reaches 100 milliseconds

Monitoring the Efficiency of theCaching MechanismEach controller in an EMC disk array can be configured to use a specified amount of memory tocache the read andor write operations The solution reports the amount of memory configured byeach controller for the read and write operations

The Write Flush Byte Rate represents the rate in MBsec at which data is committed to the disk(ie physically written) This value is to be compared with the Write Byte Rate of the disk array

55Monitoring the Efficiency of the CachingMechanism

BMC Performance Manager Express for EMC Disk Arrays

Version 2001

Comparing W rite Flush Byte Rate w ith W rite Byte Rate

The Cache Dirty Pages Percentage parameter represents the amount in percentage of the writecache that has been modified by host write operations and not yet flushed to the disks Reaching100 means that write case is too small and cannot handle the flow of write operations

Checking the Cache Dirty Pages Percentage

Reclaiming Space of Unmapped(Unused) LUNsOver time as servers connected to a SAN get decommissioned administrators find an increasingnumber of unmapped LUNs or volumes that are no longer used by any server These LUNs whileunused still occupy disk space in the disk array Being able to identify such unmapped LUNs andreclaim the disk space uselessly consumed by these LUNs will help administrators avoid unnecessaryupgrades and extensions of their disk arrays

56Reporting a Disk Space Consumption

BMC Performance Manager Express for EMC Disk Arrays

Version 2001

Reporting a Disk SpaceConsumptionMaking sure that a disk array has enough remaining disk space available is critical for severalreasons

middot SAN administrators want to make sure to be able to provision disk space for new servers whenrequested as quickly as possible

middot The disk array itself may need additional disk space for specific features to work properly likeautomatic snapshots mirroring etc

middot If thin provisioning is used the remaining disk space becomes dramatically critical since theinability to allocate additional space to a LUN when requested by the subscriber host will lead tocatastrophic data loss and corruption

The disk space used is permanently monitored for each storage pool The Subscribed Capacityparameter of the Pool class represents the amount of disk space that has been made available tothe subscriber hosts or in other words the amount of disk space that is seen by the serversconnected to disk array

The Consumed Capacity parameter of the SEN_EMC_STORAGEPOOLS class represents the actualspace usage in the storage pool For thin pools (when thin provisioning is enabled on the disk array)this value is normally lower than the Subscribed Capacity as it is the main purpose of thinprovisioning For traditional pools the Consumed Capacity parameters has the same value as theSubscribed Capacity parameter as the entirety of the subscribed disk space is fully allocated inthe storage pool

The Consumed Capacity Percentage parameter is the most critical one as a storage pool usagenearing 100 means that SAN administrators will not be able to create new LUNs in the storagepool By default no alarm or warning threshold is set on this parameter as the fullness of a storagepool may be a normal situation However you can set alert thresholds on this parameter as it fitsyour needs

57Reporting a Disk Space Consumption

BMC Performance Manager Express for EMC Disk Arrays

Detecting OversubscriptionSituations (Thin Provisioning)We call an oversubscription situation when

1 The storage pool is configured for thin provisioning (ldquothin storage poolrdquo)

2 The storage pool is oversubscribed ie the total disk space visible to the hosts (subscribers) isgreater than its actual capacity (this situation is normal for a thin pool since it is its very purpose)

3 The storage pool actual consumed capacity is nearing 100

Such situation is highly critical because the inability to allocate additional space to a LUN whenrequested by the subscriber host will lead to catastrophic data loss and corruption

When the conditions described above are met the solution sets the Oversubscription Situationparameter to 1 automatically raising a warning By default the warning for OversubscriptionSituation is issued when the Consumed Capacity Percentage parameter goes above 100 Thisthreshold can be configured in the input properties of the solution

50Detecting Oversubscription Situations (ThinProvisioning)

BMC Performance Manager Express for EMC Disk Arrays

Version 2001

Configuring Oversubscription Threshold

1 Click the EMC Disk Arrays icon and then the Configure tab

2 Edit the Oversubscription Situation Threshold () property to the appropriate value Whenthe Oversubscription Situation parameter triggers a warning it is highly recommended thatthe SAN administrators add capacity to the storage pool as soon as possible

Diagnosing Slow LUNs

If a system administrator complains that his servers are experiencing slow IOs performance and thatit is caused by the SAN you may want to verify the actual response time of the LUNs the server isrelying on

The Response Time parameter of the SEN_EMC_VOLUME class represents the average time it tookto complete the read and write operations on the LUN during the collection interval Typically theaverage response time is below 10 milliseconds You may also want to compare this value to theresponse time of the other LUNs to see whether one server is really getting worse IO performancethan another

Volume - Response Time Parameter

If the response time is low you will need to check the amount of data that is written and read onthis LUN The bad performance may simply be due to an abnormally large amount of data to processOtherwise the problem is maybe between the disk array and the server in the fiber links

51Enabling the Debug Mode

BMC Performance Manager Express for EMC Disk Arrays

Version 2001

Enabling the Debug Mode

By default BMC Performance Manager Express for EMC Disk Arrays sends only the most criticalinformation warning and error messages to the Application Collection Status parameter Mostoften this information is accurate enough to ensure that BMC Performance Manager Express for EMCDisk Arrays is functioning properly If you encounter an issue and wish to report it to customersupport you will be asked to enable the Debug Mode and provide the debug output to the supportteam

1 In the Configure tab gt under Tasks click Elements

2 Select the Element whose debug output you require and click Edit

3 Scroll down to Application Classes gt click the Application class for which you want toenable the debug mode gt click Edit

4 Select Yes from the drop-down Debug Mode list gt SaveBy default BMC Performance Manager Express for EMC Disk Arrays sends its debug output to RSM_HOMERSM(xx)serverrsmlogsen_debuglog

5 Wait for 15 minutes and then disable the debug mode by selecting No

6 Send the debug file to the support team

Pay attention to the file size -the debug output of BMC Performance Manager Express for EMC Disk Arrays could bevery large if enabled for several days

Identifying the Hosts that canAccess a LUNIn most SAN configurations each LUN belongs to a storage group whose host members are the onlyones authorized to access the LUN This is called LUN masking For each LUN the solution displaysits WWN the storage group to which it belongs to as well as the hosts member of this group Inmost cases identifying the storage group of a LUN is sufficient to recognize the server that is usingit

52Identifying LUNs not Owned by their Normal(Default) Storage Processor

BMC Performance Manager Express for EMC Disk Arrays

Version 2001

Identifying LUNs not Owned bytheir Normal (Default) StorageProcessorThe Owning Storage Processor parameter reports the name of the controller that handles IOsfor each LUN If a LUN is not currently handled by its normal (default) storage processors the nameof the default controller will be indicated as SP_B (default SP_A)rdquo

To identify LUNs that are not owned by their normal storage processor you simply need to list the Volume objects where the Owning Storage Processor parameter contains the string Default

Identifying Most Busy LUNs

To identify the LUNs that generate the most traffic on the disk array use the Read Byte Rate andWrite Byte Rate parameters of the LUN class that expose the data throughput for each LUN Usethese parameters to report on the total data traffic (per hour or per day) on each LUN in GB

To make sure that traffic is displayed cumulatively per hour select a time window of at least 12 hours in the graphwindow select at least 7 days to visualize per day cumulative data

1 In the Status tab click the Volume for which you need to check the LUNs activity then expandthe LUNs object to display the ReadWrite Byte Rate parameters

53Identifying Most Busy LUNs

Version 2001

2 Click the History icon to automatically display a graph that shows the ReadWrite Byte Ratevalues collected for a selected parameter during the previous six hours You can customize thechart and table to show parameter history for different time periods

54Identifying Most Busy LUNs

BMC Performance Manager Express for EMC Disk Arrays

Version 2001

View ing a LUNs ReadW rite Byte Rate as a graph

Identifying a Storage Processor(Controllers) OverloadTo visualize the activity of a controller in an EMC disk array use the Processor Utilizationparameter of the SEN_EMC_CONTROLLER class A warning is issued when the processor utilizationgoes too high which means that the controllers cannot keep up with the load on the disk array It isthen important to identify what is overloading the controllers

The Response Time parameter of the SEN_EMC_CONTROLLER class represents the average time ittook the controller to process the read and write requests of the hosts The higher the ResponseTime goes the slower IOs the servers will get By default the solution triggers a warning when thecontroller takes more than 10 milliseconds on average to complete the IO requests and an alarmwhen the response time reaches 100 milliseconds

Monitoring the Efficiency of theCaching MechanismEach controller in an EMC disk array can be configured to use a specified amount of memory tocache the read andor write operations The solution reports the amount of memory configured byeach controller for the read and write operations

The Write Flush Byte Rate represents the rate in MBsec at which data is committed to the disk(ie physically written) This value is to be compared with the Write Byte Rate of the disk array

55Monitoring the Efficiency of the CachingMechanism

BMC Performance Manager Express for EMC Disk Arrays

Version 2001

Comparing W rite Flush Byte Rate w ith W rite Byte Rate

The Cache Dirty Pages Percentage parameter represents the amount in percentage of the writecache that has been modified by host write operations and not yet flushed to the disks Reaching100 means that write case is too small and cannot handle the flow of write operations

Checking the Cache Dirty Pages Percentage

Reclaiming Space of Unmapped(Unused) LUNsOver time as servers connected to a SAN get decommissioned administrators find an increasingnumber of unmapped LUNs or volumes that are no longer used by any server These LUNs whileunused still occupy disk space in the disk array Being able to identify such unmapped LUNs andreclaim the disk space uselessly consumed by these LUNs will help administrators avoid unnecessaryupgrades and extensions of their disk arrays

56Reporting a Disk Space Consumption

BMC Performance Manager Express for EMC Disk Arrays

Version 2001

Reporting a Disk SpaceConsumptionMaking sure that a disk array has enough remaining disk space available is critical for severalreasons

middot SAN administrators want to make sure to be able to provision disk space for new servers whenrequested as quickly as possible

middot The disk array itself may need additional disk space for specific features to work properly likeautomatic snapshots mirroring etc

middot If thin provisioning is used the remaining disk space becomes dramatically critical since theinability to allocate additional space to a LUN when requested by the subscriber host will lead tocatastrophic data loss and corruption

The disk space used is permanently monitored for each storage pool The Subscribed Capacityparameter of the Pool class represents the amount of disk space that has been made available tothe subscriber hosts or in other words the amount of disk space that is seen by the serversconnected to disk array

The Consumed Capacity parameter of the SEN_EMC_STORAGEPOOLS class represents the actualspace usage in the storage pool For thin pools (when thin provisioning is enabled on the disk array)this value is normally lower than the Subscribed Capacity as it is the main purpose of thinprovisioning For traditional pools the Consumed Capacity parameters has the same value as theSubscribed Capacity parameter as the entirety of the subscribed disk space is fully allocated inthe storage pool

The Consumed Capacity Percentage parameter is the most critical one as a storage pool usagenearing 100 means that SAN administrators will not be able to create new LUNs in the storagepool By default no alarm or warning threshold is set on this parameter as the fullness of a storagepool may be a normal situation However you can set alert thresholds on this parameter as it fitsyour needs

57Reporting a Disk Space Consumption

Setting thresholds

Whenever relevant BMC Performance Manager Express for EMC Disk Arrays automatically setsthresholds for parameters If you prefer a more fault-tolerant monitoring you can modify thethresholds of each parameter through the Configure tab gt Edit Thresholds

It is strongly recommended to wait for all the storage objects to be discovered before setting threshold values to avoidhaving to enter thresholds for each occurrence of the application class

To modify the parameter thresholds of several storage objects of an element

60Setting thresholds

BMC Performance Manager Express for EMC Disk Arrays

Version 2001

1 In the Configure tab click on the Storage (ltplatformgt) or the instance icon gt Edit

Thresholds Properties and Credentials

Any modification to the thresholds or any other properties of elements created using the Element

Profile mode is to be done using the Element Profile route or by clicking Override Profile

2 Uncheck the Warning and Alarm boxes for all the parameters for which you want to disablethe alert conditions

Alerts are displayed by the parameter whose thresholds are modified

Viewing the Overall Activity of aDisk ArrayIn order to visualize the activity of a disk array use the Read Byte Rate and Write Byte Rate ofthe SEN_EMC_ARRAY class These parameters represent the overall traffic in megabytes per secondfor each monitored array or more precisely each EMC disk array that is exposed through the EMCSMI-S Provider (see the EMC_SMI-S_Provider section of the Installation Guide for more informationabout the EMC SMI-S Provider)

62Viewing the Overall Activity of a Disk Array

BMC Performance Manager Express for EMC Disk Arrays

50Detecting Oversubscription Situations (ThinProvisioning)

BMC Performance Manager Express for EMC Disk Arrays

Version 2001

Configuring Oversubscription Threshold

1 Click the EMC Disk Arrays icon and then the Configure tab

2 Edit the Oversubscription Situation Threshold () property to the appropriate value Whenthe Oversubscription Situation parameter triggers a warning it is highly recommended thatthe SAN administrators add capacity to the storage pool as soon as possible

Diagnosing Slow LUNs

If a system administrator complains that his servers are experiencing slow IOs performance and thatit is caused by the SAN you may want to verify the actual response time of the LUNs the server isrelying on

The Response Time parameter of the SEN_EMC_VOLUME class represents the average time it tookto complete the read and write operations on the LUN during the collection interval Typically theaverage response time is below 10 milliseconds You may also want to compare this value to theresponse time of the other LUNs to see whether one server is really getting worse IO performancethan another

Volume - Response Time Parameter

If the response time is low you will need to check the amount of data that is written and read onthis LUN The bad performance may simply be due to an abnormally large amount of data to processOtherwise the problem is maybe between the disk array and the server in the fiber links

51Enabling the Debug Mode

BMC Performance Manager Express for EMC Disk Arrays

Version 2001

Enabling the Debug Mode

By default BMC Performance Manager Express for EMC Disk Arrays sends only the most criticalinformation warning and error messages to the Application Collection Status parameter Mostoften this information is accurate enough to ensure that BMC Performance Manager Express for EMCDisk Arrays is functioning properly If you encounter an issue and wish to report it to customersupport you will be asked to enable the Debug Mode and provide the debug output to the supportteam

1 In the Configure tab gt under Tasks click Elements

2 Select the Element whose debug output you require and click Edit

3 Scroll down to Application Classes gt click the Application class for which you want toenable the debug mode gt click Edit

4 Select Yes from the drop-down Debug Mode list gt SaveBy default BMC Performance Manager Express for EMC Disk Arrays sends its debug output to RSM_HOMERSM(xx)serverrsmlogsen_debuglog

5 Wait for 15 minutes and then disable the debug mode by selecting No

6 Send the debug file to the support team

Pay attention to the file size -the debug output of BMC Performance Manager Express for EMC Disk Arrays could bevery large if enabled for several days

Identifying the Hosts that canAccess a LUNIn most SAN configurations each LUN belongs to a storage group whose host members are the onlyones authorized to access the LUN This is called LUN masking For each LUN the solution displaysits WWN the storage group to which it belongs to as well as the hosts member of this group Inmost cases identifying the storage group of a LUN is sufficient to recognize the server that is usingit

52Identifying LUNs not Owned by their Normal(Default) Storage Processor

BMC Performance Manager Express for EMC Disk Arrays

Version 2001

Identifying LUNs not Owned bytheir Normal (Default) StorageProcessorThe Owning Storage Processor parameter reports the name of the controller that handles IOsfor each LUN If a LUN is not currently handled by its normal (default) storage processors the nameof the default controller will be indicated as SP_B (default SP_A)rdquo

To identify LUNs that are not owned by their normal storage processor you simply need to list the Volume objects where the Owning Storage Processor parameter contains the string Default

Identifying Most Busy LUNs

To identify the LUNs that generate the most traffic on the disk array use the Read Byte Rate andWrite Byte Rate parameters of the LUN class that expose the data throughput for each LUN Usethese parameters to report on the total data traffic (per hour or per day) on each LUN in GB

To make sure that traffic is displayed cumulatively per hour select a time window of at least 12 hours in the graphwindow select at least 7 days to visualize per day cumulative data

1 In the Status tab click the Volume for which you need to check the LUNs activity then expandthe LUNs object to display the ReadWrite Byte Rate parameters

53Identifying Most Busy LUNs

Identifying a Storage Processor(Controllers) OverloadTo visualize the activity of a controller in an EMC disk array use the Processor Utilizationparameter of the SEN_EMC_CONTROLLER class A warning is issued when the processor utilizationgoes too high which means that the controllers cannot keep up with the load on the disk array It isthen important to identify what is overloading the controllers

The Response Time parameter of the SEN_EMC_CONTROLLER class represents the average time ittook the controller to process the read and write requests of the hosts The higher the ResponseTime goes the slower IOs the servers will get By default the solution triggers a warning when thecontroller takes more than 10 milliseconds on average to complete the IO requests and an alarmwhen the response time reaches 100 milliseconds

Monitoring the Efficiency of theCaching MechanismEach controller in an EMC disk array can be configured to use a specified amount of memory tocache the read andor write operations The solution reports the amount of memory configured byeach controller for the read and write operations

The Write Flush Byte Rate represents the rate in MBsec at which data is committed to the disk(ie physically written) This value is to be compared with the Write Byte Rate of the disk array

55Monitoring the Efficiency of the CachingMechanism

BMC Performance Manager Express for EMC Disk Arrays

Version 2001

Comparing W rite Flush Byte Rate w ith W rite Byte Rate

The Cache Dirty Pages Percentage parameter represents the amount in percentage of the writecache that has been modified by host write operations and not yet flushed to the disks Reaching100 means that write case is too small and cannot handle the flow of write operations

Checking the Cache Dirty Pages Percentage

Reclaiming Space of Unmapped(Unused) LUNsOver time as servers connected to a SAN get decommissioned administrators find an increasingnumber of unmapped LUNs or volumes that are no longer used by any server These LUNs whileunused still occupy disk space in the disk array Being able to identify such unmapped LUNs andreclaim the disk space uselessly consumed by these LUNs will help administrators avoid unnecessaryupgrades and extensions of their disk arrays

56Reporting a Disk Space Consumption

BMC Performance Manager Express for EMC Disk Arrays

Version 2001

Reporting a Disk SpaceConsumptionMaking sure that a disk array has enough remaining disk space available is critical for severalreasons

middot SAN administrators want to make sure to be able to provision disk space for new servers whenrequested as quickly as possible

middot The disk array itself may need additional disk space for specific features to work properly likeautomatic snapshots mirroring etc

middot If thin provisioning is used the remaining disk space becomes dramatically critical since theinability to allocate additional space to a LUN when requested by the subscriber host will lead tocatastrophic data loss and corruption

The disk space used is permanently monitored for each storage pool The Subscribed Capacityparameter of the Pool class represents the amount of disk space that has been made available tothe subscriber hosts or in other words the amount of disk space that is seen by the serversconnected to disk array

The Consumed Capacity parameter of the SEN_EMC_STORAGEPOOLS class represents the actualspace usage in the storage pool For thin pools (when thin provisioning is enabled on the disk array)this value is normally lower than the Subscribed Capacity as it is the main purpose of thinprovisioning For traditional pools the Consumed Capacity parameters has the same value as theSubscribed Capacity parameter as the entirety of the subscribed disk space is fully allocated inthe storage pool

The Consumed Capacity Percentage parameter is the most critical one as a storage pool usagenearing 100 means that SAN administrators will not be able to create new LUNs in the storagepool By default no alarm or warning threshold is set on this parameter as the fullness of a storagepool may be a normal situation However you can set alert thresholds on this parameter as it fitsyour needs

57Reporting a Disk Space Consumption

BMC Performance Manager Express for EMC Disk Arrays

Version 2001

Verifying the Available Disk Space in the Storage Pool of your EMC DiskArrays

1 In the Configure tab select an element group in the tree view (the main ldquoInfrastructurerdquogroup for example)

2 Click on the Reports tab

3 Create a report for the last 24 hours top 50 values of the Array|Storage Pools|Disk Group|Storage Pool|Consumed Capacity Percentage parameter of the EMC Disk Arraysapplication class for the BMC Performance Manager Express for EMC Disk Arrays by SentrySoftware solution

Report ndash Disk Space Consumption

Reporting the Total Traffic on anHourly or Daily BasisBMC Performance Manager Express for EMC Disk Arrays not only monitors the traffic and activity ofthe disk array controllers LUNs and physical disks in MBsec but also in GB per hour or per day Theexact amount of data that was read or written to the disk array LUN or physical disk is calculated foreach hour of the day and each day of the week

Each data rate parameter in MBsec is accompanied by a non-rate one in GB These parameters areldquocumulativerdquo their instantaneous value has no meaning and they need to be visualized in a longperiod of time (instead of Read Byte Rate or Write Byte Rate)

58Reporting the Total Traffic on an Hourly orDaily Basis

Setting thresholds

Whenever relevant BMC Performance Manager Express for EMC Disk Arrays automatically setsthresholds for parameters If you prefer a more fault-tolerant monitoring you can modify thethresholds of each parameter through the Configure tab gt Edit Thresholds

It is strongly recommended to wait for all the storage objects to be discovered before setting threshold values to avoidhaving to enter thresholds for each occurrence of the application class

To modify the parameter thresholds of several storage objects of an element

60Setting thresholds

BMC Performance Manager Express for EMC Disk Arrays

Version 2001

1 In the Configure tab click on the Storage (ltplatformgt) or the instance icon gt Edit

Thresholds Properties and Credentials

Any modification to the thresholds or any other properties of elements created using the Element

Profile mode is to be done using the Element Profile route or by clicking Override Profile

2 Uncheck the Warning and Alarm boxes for all the parameters for which you want to disablethe alert conditions

Alerts are displayed by the parameter whose thresholds are modified

Viewing the Overall Activity of aDisk ArrayIn order to visualize the activity of a disk array use the Read Byte Rate and Write Byte Rate ofthe SEN_EMC_ARRAY class These parameters represent the overall traffic in megabytes per secondfor each monitored array or more precisely each EMC disk array that is exposed through the EMCSMI-S Provider (see the EMC_SMI-S_Provider section of the Installation Guide for more informationabout the EMC SMI-S Provider)

62Viewing the Overall Activity of a Disk Array

BMC Performance Manager Express for EMC Disk Arrays

Enabling the Debug Mode

By default BMC Performance Manager Express for EMC Disk Arrays sends only the most criticalinformation warning and error messages to the Application Collection Status parameter Mostoften this information is accurate enough to ensure that BMC Performance Manager Express for EMCDisk Arrays is functioning properly If you encounter an issue and wish to report it to customersupport you will be asked to enable the Debug Mode and provide the debug output to the supportteam

1 In the Configure tab gt under Tasks click Elements

2 Select the Element whose debug output you require and click Edit

3 Scroll down to Application Classes gt click the Application class for which you want toenable the debug mode gt click Edit

4 Select Yes from the drop-down Debug Mode list gt SaveBy default BMC Performance Manager Express for EMC Disk Arrays sends its debug output to RSM_HOMERSM(xx)serverrsmlogsen_debuglog

5 Wait for 15 minutes and then disable the debug mode by selecting No

6 Send the debug file to the support team

Pay attention to the file size -the debug output of BMC Performance Manager Express for EMC Disk Arrays could bevery large if enabled for several days

Identifying the Hosts that canAccess a LUNIn most SAN configurations each LUN belongs to a storage group whose host members are the onlyones authorized to access the LUN This is called LUN masking For each LUN the solution displaysits WWN the storage group to which it belongs to as well as the hosts member of this group Inmost cases identifying the storage group of a LUN is sufficient to recognize the server that is usingit

52Identifying LUNs not Owned by their Normal(Default) Storage Processor

BMC Performance Manager Express for EMC Disk Arrays

Version 2001

Identifying LUNs not Owned bytheir Normal (Default) StorageProcessorThe Owning Storage Processor parameter reports the name of the controller that handles IOsfor each LUN If a LUN is not currently handled by its normal (default) storage processors the nameof the default controller will be indicated as SP_B (default SP_A)rdquo

To identify LUNs that are not owned by their normal storage processor you simply need to list the Volume objects where the Owning Storage Processor parameter contains the string Default

Identifying Most Busy LUNs

To identify the LUNs that generate the most traffic on the disk array use the Read Byte Rate andWrite Byte Rate parameters of the LUN class that expose the data throughput for each LUN Usethese parameters to report on the total data traffic (per hour or per day) on each LUN in GB

To make sure that traffic is displayed cumulatively per hour select a time window of at least 12 hours in the graphwindow select at least 7 days to visualize per day cumulative data

1 In the Status tab click the Volume for which you need to check the LUNs activity then expandthe LUNs object to display the ReadWrite Byte Rate parameters

53Identifying Most Busy LUNs

Version 2001

View ing a LUNs ReadW rite Byte Rate as a graph

Identifying a Storage Processor(Controllers) OverloadTo visualize the activity of a controller in an EMC disk array use the Processor Utilizationparameter of the SEN_EMC_CONTROLLER class A warning is issued when the processor utilizationgoes too high which means that the controllers cannot keep up with the load on the disk array It isthen important to identify what is overloading the controllers

The Response Time parameter of the SEN_EMC_CONTROLLER class represents the average time ittook the controller to process the read and write requests of the hosts The higher the ResponseTime goes the slower IOs the servers will get By default the solution triggers a warning when thecontroller takes more than 10 milliseconds on average to complete the IO requests and an alarmwhen the response time reaches 100 milliseconds

Monitoring the Efficiency of theCaching MechanismEach controller in an EMC disk array can be configured to use a specified amount of memory tocache the read andor write operations The solution reports the amount of memory configured byeach controller for the read and write operations

The Write Flush Byte Rate represents the rate in MBsec at which data is committed to the disk(ie physically written) This value is to be compared with the Write Byte Rate of the disk array

55Monitoring the Efficiency of the CachingMechanism

BMC Performance Manager Express for EMC Disk Arrays

Version 2001

Comparing W rite Flush Byte Rate w ith W rite Byte Rate

The Cache Dirty Pages Percentage parameter represents the amount in percentage of the writecache that has been modified by host write operations and not yet flushed to the disks Reaching100 means that write case is too small and cannot handle the flow of write operations

Checking the Cache Dirty Pages Percentage

Reclaiming Space of Unmapped(Unused) LUNsOver time as servers connected to a SAN get decommissioned administrators find an increasingnumber of unmapped LUNs or volumes that are no longer used by any server These LUNs whileunused still occupy disk space in the disk array Being able to identify such unmapped LUNs andreclaim the disk space uselessly consumed by these LUNs will help administrators avoid unnecessaryupgrades and extensions of their disk arrays

56Reporting a Disk Space Consumption

BMC Performance Manager Express for EMC Disk Arrays

Version 2001

Reporting a Disk SpaceConsumptionMaking sure that a disk array has enough remaining disk space available is critical for severalreasons

middot SAN administrators want to make sure to be able to provision disk space for new servers whenrequested as quickly as possible

middot The disk array itself may need additional disk space for specific features to work properly likeautomatic snapshots mirroring etc

middot If thin provisioning is used the remaining disk space becomes dramatically critical since theinability to allocate additional space to a LUN when requested by the subscriber host will lead tocatastrophic data loss and corruption

The disk space used is permanently monitored for each storage pool The Subscribed Capacityparameter of the Pool class represents the amount of disk space that has been made available tothe subscriber hosts or in other words the amount of disk space that is seen by the serversconnected to disk array

The Consumed Capacity parameter of the SEN_EMC_STORAGEPOOLS class represents the actualspace usage in the storage pool For thin pools (when thin provisioning is enabled on the disk array)this value is normally lower than the Subscribed Capacity as it is the main purpose of thinprovisioning For traditional pools the Consumed Capacity parameters has the same value as theSubscribed Capacity parameter as the entirety of the subscribed disk space is fully allocated inthe storage pool

The Consumed Capacity Percentage parameter is the most critical one as a storage pool usagenearing 100 means that SAN administrators will not be able to create new LUNs in the storagepool By default no alarm or warning threshold is set on this parameter as the fullness of a storagepool may be a normal situation However you can set alert thresholds on this parameter as it fitsyour needs

57Reporting a Disk Space Consumption

BMC Performance Manager Express for EMC Disk Arrays

Version 2001

Verifying the Available Disk Space in the Storage Pool of your EMC DiskArrays

1 In the Configure tab select an element group in the tree view (the main ldquoInfrastructurerdquogroup for example)

3 Create a report for the last 24 hours top 50 values of the Array|Storage Pools|Disk Group|Storage Pool|Consumed Capacity Percentage parameter of the EMC Disk Arraysapplication class for the BMC Performance Manager Express for EMC Disk Arrays by SentrySoftware solution

Report ndash Disk Space Consumption

Reporting the Total Traffic on anHourly or Daily BasisBMC Performance Manager Express for EMC Disk Arrays not only monitors the traffic and activity ofthe disk array controllers LUNs and physical disks in MBsec but also in GB per hour or per day Theexact amount of data that was read or written to the disk array LUN or physical disk is calculated foreach hour of the day and each day of the week

Each data rate parameter in MBsec is accompanied by a non-rate one in GB These parameters areldquocumulativerdquo their instantaneous value has no meaning and they need to be visualized in a longperiod of time (instead of Read Byte Rate or Write Byte Rate)

58Reporting the Total Traffic on an Hourly orDaily Basis

52Identifying LUNs not Owned by their Normal(Default) Storage Processor

BMC Performance Manager Express for EMC Disk Arrays

Version 2001

Identifying LUNs not Owned bytheir Normal (Default) StorageProcessorThe Owning Storage Processor parameter reports the name of the controller that handles IOsfor each LUN If a LUN is not currently handled by its normal (default) storage processors the nameof the default controller will be indicated as SP_B (default SP_A)rdquo

To identify LUNs that are not owned by their normal storage processor you simply need to list the Volume objects where the Owning Storage Processor parameter contains the string Default

Identifying Most Busy LUNs

To identify the LUNs that generate the most traffic on the disk array use the Read Byte Rate andWrite Byte Rate parameters of the LUN class that expose the data throughput for each LUN Usethese parameters to report on the total data traffic (per hour or per day) on each LUN in GB

To make sure that traffic is displayed cumulatively per hour select a time window of at least 12 hours in the graphwindow select at least 7 days to visualize per day cumulative data

1 In the Status tab click the Volume for which you need to check the LUNs activity then expandthe LUNs object to display the ReadWrite Byte Rate parameters

53Identifying Most Busy LUNs

Version 2001

View ing a LUNs ReadW rite Byte Rate as a graph

Identifying a Storage Processor(Controllers) OverloadTo visualize the activity of a controller in an EMC disk array use the Processor Utilizationparameter of the SEN_EMC_CONTROLLER class A warning is issued when the processor utilizationgoes too high which means that the controllers cannot keep up with the load on the disk array It isthen important to identify what is overloading the controllers

The Response Time parameter of the SEN_EMC_CONTROLLER class represents the average time ittook the controller to process the read and write requests of the hosts The higher the ResponseTime goes the slower IOs the servers will get By default the solution triggers a warning when thecontroller takes more than 10 milliseconds on average to complete the IO requests and an alarmwhen the response time reaches 100 milliseconds

Monitoring the Efficiency of theCaching MechanismEach controller in an EMC disk array can be configured to use a specified amount of memory tocache the read andor write operations The solution reports the amount of memory configured byeach controller for the read and write operations

The Write Flush Byte Rate represents the rate in MBsec at which data is committed to the disk(ie physically written) This value is to be compared with the Write Byte Rate of the disk array

55Monitoring the Efficiency of the CachingMechanism

BMC Performance Manager Express for EMC Disk Arrays

Version 2001

Comparing W rite Flush Byte Rate w ith W rite Byte Rate

The Cache Dirty Pages Percentage parameter represents the amount in percentage of the writecache that has been modified by host write operations and not yet flushed to the disks Reaching100 means that write case is too small and cannot handle the flow of write operations

Checking the Cache Dirty Pages Percentage

Reclaiming Space of Unmapped(Unused) LUNsOver time as servers connected to a SAN get decommissioned administrators find an increasingnumber of unmapped LUNs or volumes that are no longer used by any server These LUNs whileunused still occupy disk space in the disk array Being able to identify such unmapped LUNs andreclaim the disk space uselessly consumed by these LUNs will help administrators avoid unnecessaryupgrades and extensions of their disk arrays

56Reporting a Disk Space Consumption

BMC Performance Manager Express for EMC Disk Arrays

Version 2001

Reporting a Disk SpaceConsumptionMaking sure that a disk array has enough remaining disk space available is critical for severalreasons

middot SAN administrators want to make sure to be able to provision disk space for new servers whenrequested as quickly as possible

middot The disk array itself may need additional disk space for specific features to work properly likeautomatic snapshots mirroring etc

middot If thin provisioning is used the remaining disk space becomes dramatically critical since theinability to allocate additional space to a LUN when requested by the subscriber host will lead tocatastrophic data loss and corruption

The disk space used is permanently monitored for each storage pool The Subscribed Capacityparameter of the Pool class represents the amount of disk space that has been made available tothe subscriber hosts or in other words the amount of disk space that is seen by the serversconnected to disk array

The Consumed Capacity parameter of the SEN_EMC_STORAGEPOOLS class represents the actualspace usage in the storage pool For thin pools (when thin provisioning is enabled on the disk array)this value is normally lower than the Subscribed Capacity as it is the main purpose of thinprovisioning For traditional pools the Consumed Capacity parameters has the same value as theSubscribed Capacity parameter as the entirety of the subscribed disk space is fully allocated inthe storage pool

The Consumed Capacity Percentage parameter is the most critical one as a storage pool usagenearing 100 means that SAN administrators will not be able to create new LUNs in the storagepool By default no alarm or warning threshold is set on this parameter as the fullness of a storagepool may be a normal situation However you can set alert thresholds on this parameter as it fitsyour needs

57Reporting a Disk Space Consumption

BMC Performance Manager Express for EMC Disk Arrays

Version 2001

Verifying the Available Disk Space in the Storage Pool of your EMC DiskArrays

1 In the Configure tab select an element group in the tree view (the main ldquoInfrastructurerdquogroup for example)

2 Click on the Reports tab

3 Create a report for the last 24 hours top 50 values of the Array|Storage Pools|Disk Group|Storage Pool|Consumed Capacity Percentage parameter of the EMC Disk Arraysapplication class for the BMC Performance Manager Express for EMC Disk Arrays by SentrySoftware solution

Report ndash Disk Space Consumption

Reporting the Total Traffic on anHourly or Daily BasisBMC Performance Manager Express for EMC Disk Arrays not only monitors the traffic and activity ofthe disk array controllers LUNs and physical disks in MBsec but also in GB per hour or per day Theexact amount of data that was read or written to the disk array LUN or physical disk is calculated foreach hour of the day and each day of the week

Each data rate parameter in MBsec is accompanied by a non-rate one in GB These parameters areldquocumulativerdquo their instantaneous value has no meaning and they need to be visualized in a longperiod of time (instead of Read Byte Rate or Write Byte Rate)

58Reporting the Total Traffic on an Hourly orDaily Basis

BMC Performance Manager Express for EMC Disk Arrays

Setting thresholds

Whenever relevant BMC Performance Manager Express for EMC Disk Arrays automatically setsthresholds for parameters If you prefer a more fault-tolerant monitoring you can modify thethresholds of each parameter through the Configure tab gt Edit Thresholds

It is strongly recommended to wait for all the storage objects to be discovered before setting threshold values to avoidhaving to enter thresholds for each occurrence of the application class

To modify the parameter thresholds of several storage objects of an element

60Setting thresholds

54Identifying Most Busy LUNs

BMC Performance Manager Express for EMC Disk Arrays

Version 2001

View ing a LUNs ReadW rite Byte Rate as a graph

Identifying a Storage Processor(Controllers) OverloadTo visualize the activity of a controller in an EMC disk array use the Processor Utilizationparameter of the SEN_EMC_CONTROLLER class A warning is issued when the processor utilizationgoes too high which means that the controllers cannot keep up with the load on the disk array It isthen important to identify what is overloading the controllers

The Response Time parameter of the SEN_EMC_CONTROLLER class represents the average time ittook the controller to process the read and write requests of the hosts The higher the ResponseTime goes the slower IOs the servers will get By default the solution triggers a warning when thecontroller takes more than 10 milliseconds on average to complete the IO requests and an alarmwhen the response time reaches 100 milliseconds

Monitoring the Efficiency of theCaching MechanismEach controller in an EMC disk array can be configured to use a specified amount of memory tocache the read andor write operations The solution reports the amount of memory configured byeach controller for the read and write operations

The Write Flush Byte Rate represents the rate in MBsec at which data is committed to the disk(ie physically written) This value is to be compared with the Write Byte Rate of the disk array

55Monitoring the Efficiency of the CachingMechanism

BMC Performance Manager Express for EMC Disk Arrays

Version 2001

Comparing W rite Flush Byte Rate w ith W rite Byte Rate

The Cache Dirty Pages Percentage parameter represents the amount in percentage of the writecache that has been modified by host write operations and not yet flushed to the disks Reaching100 means that write case is too small and cannot handle the flow of write operations

Checking the Cache Dirty Pages Percentage

Reclaiming Space of Unmapped(Unused) LUNsOver time as servers connected to a SAN get decommissioned administrators find an increasingnumber of unmapped LUNs or volumes that are no longer used by any server These LUNs whileunused still occupy disk space in the disk array Being able to identify such unmapped LUNs andreclaim the disk space uselessly consumed by these LUNs will help administrators avoid unnecessaryupgrades and extensions of their disk arrays

56Reporting a Disk Space Consumption

BMC Performance Manager Express for EMC Disk Arrays

Version 2001

Reporting a Disk SpaceConsumptionMaking sure that a disk array has enough remaining disk space available is critical for severalreasons

middot SAN administrators want to make sure to be able to provision disk space for new servers whenrequested as quickly as possible

middot The disk array itself may need additional disk space for specific features to work properly likeautomatic snapshots mirroring etc

middot If thin provisioning is used the remaining disk space becomes dramatically critical since theinability to allocate additional space to a LUN when requested by the subscriber host will lead tocatastrophic data loss and corruption

The disk space used is permanently monitored for each storage pool The Subscribed Capacityparameter of the Pool class represents the amount of disk space that has been made available tothe subscriber hosts or in other words the amount of disk space that is seen by the serversconnected to disk array

The Consumed Capacity parameter of the SEN_EMC_STORAGEPOOLS class represents the actualspace usage in the storage pool For thin pools (when thin provisioning is enabled on the disk array)this value is normally lower than the Subscribed Capacity as it is the main purpose of thinprovisioning For traditional pools the Consumed Capacity parameters has the same value as theSubscribed Capacity parameter as the entirety of the subscribed disk space is fully allocated inthe storage pool

The Consumed Capacity Percentage parameter is the most critical one as a storage pool usagenearing 100 means that SAN administrators will not be able to create new LUNs in the storagepool By default no alarm or warning threshold is set on this parameter as the fullness of a storagepool may be a normal situation However you can set alert thresholds on this parameter as it fitsyour needs

57Reporting a Disk Space Consumption

BMC Performance Manager Express for EMC Disk Arrays

Version 2001

Verifying the Available Disk Space in the Storage Pool of your EMC DiskArrays

1 In the Configure tab select an element group in the tree view (the main ldquoInfrastructurerdquogroup for example)

2 Click on the Reports tab

3 Create a report for the last 24 hours top 50 values of the Array|Storage Pools|Disk Group|Storage Pool|Consumed Capacity Percentage parameter of the EMC Disk Arraysapplication class for the BMC Performance Manager Express for EMC Disk Arrays by SentrySoftware solution

Report ndash Disk Space Consumption

Reporting the Total Traffic on anHourly or Daily BasisBMC Performance Manager Express for EMC Disk Arrays not only monitors the traffic and activity ofthe disk array controllers LUNs and physical disks in MBsec but also in GB per hour or per day Theexact amount of data that was read or written to the disk array LUN or physical disk is calculated foreach hour of the day and each day of the week

Each data rate parameter in MBsec is accompanied by a non-rate one in GB These parameters areldquocumulativerdquo their instantaneous value has no meaning and they need to be visualized in a longperiod of time (instead of Read Byte Rate or Write Byte Rate)

58Reporting the Total Traffic on an Hourly orDaily Basis

BMC Performance Manager Express for EMC Disk Arrays

Version 2001

Generating a Disk Array Usage Report

1 Click the Status tab in Portal

2 When viewing the status of the disk array controller LUN or physical disk click on the graphicon of the Read Bytes or Write Bytes parameter

Setting thresholds

Whenever relevant BMC Performance Manager Express for EMC Disk Arrays automatically setsthresholds for parameters If you prefer a more fault-tolerant monitoring you can modify thethresholds of each parameter through the Configure tab gt Edit Thresholds

It is strongly recommended to wait for all the storage objects to be discovered before setting threshold values to avoidhaving to enter thresholds for each occurrence of the application class

To modify the parameter thresholds of several storage objects of an element

60Setting thresholds

BMC Performance Manager Express for EMC Disk Arrays

Version 2001

1 In the Configure tab click on the Storage (ltplatformgt) or the instance icon gt Edit

Thresholds Properties and Credentials

Any modification to the thresholds or any other properties of elements created using the Element

Profile mode is to be done using the Element Profile route or by clicking Override Profile

2 Uncheck the Warning and Alarm boxes for all the parameters for which you want to disablethe alert conditions

Disabling the default alert thresholds

61Setting thresholds

BMC Performance Manager Express for EMC Disk Arrays

Version 2001

3 Check the Warning and Alarm boxes for all the parameters for which you want to enable thealert conditions You will then have to manually enter the threshold values and check the Activebox In the example below a Warning will be triggered if Status is greater than 1 an alarm willbe triggered when greater than 2

Modifying threshold values

4 Click Save

5 The Success changes have been saved message indicates that the modifications have beenregistered

Alerts are displayed by the parameter whose thresholds are modified

Viewing the Overall Activity of aDisk ArrayIn order to visualize the activity of a disk array use the Read Byte Rate and Write Byte Rate ofthe SEN_EMC_ARRAY class These parameters represent the overall traffic in megabytes per secondfor each monitored array or more precisely each EMC disk array that is exposed through the EMCSMI-S Provider (see the EMC_SMI-S_Provider section of the Installation Guide for more informationabout the EMC SMI-S Provider)

62Viewing the Overall Activity of a Disk Array

BMC Performance Manager Express for EMC Disk Arrays

Version 2001

Viewing a Disk Array Activity

1 Click the Status tab in Portal

2 Click the array icon in the tree view to visualize its current activity

54Identifying Most Busy LUNs

BMC Performance Manager Express for EMC Disk Arrays

Version 2001

View ing a LUNs ReadW rite Byte Rate as a graph

Identifying a Storage Processor(Controllers) OverloadTo visualize the activity of a controller in an EMC disk array use the Processor Utilizationparameter of the SEN_EMC_CONTROLLER class A warning is issued when the processor utilizationgoes too high which means that the controllers cannot keep up with the load on the disk array It isthen important to identify what is overloading the controllers

The Response Time parameter of the SEN_EMC_CONTROLLER class represents the average time ittook the controller to process the read and write requests of the hosts The higher the ResponseTime goes the slower IOs the servers will get By default the solution triggers a warning when thecontroller takes more than 10 milliseconds on average to complete the IO requests and an alarmwhen the response time reaches 100 milliseconds

Monitoring the Efficiency of theCaching MechanismEach controller in an EMC disk array can be configured to use a specified amount of memory tocache the read andor write operations The solution reports the amount of memory configured byeach controller for the read and write operations

The Write Flush Byte Rate represents the rate in MBsec at which data is committed to the disk(ie physically written) This value is to be compared with the Write Byte Rate of the disk array

55Monitoring the Efficiency of the CachingMechanism

BMC Performance Manager Express for EMC Disk Arrays

Version 2001

Comparing W rite Flush Byte Rate w ith W rite Byte Rate

The Cache Dirty Pages Percentage parameter represents the amount in percentage of the writecache that has been modified by host write operations and not yet flushed to the disks Reaching100 means that write case is too small and cannot handle the flow of write operations

Checking the Cache Dirty Pages Percentage

Reclaiming Space of Unmapped(Unused) LUNsOver time as servers connected to a SAN get decommissioned administrators find an increasingnumber of unmapped LUNs or volumes that are no longer used by any server These LUNs whileunused still occupy disk space in the disk array Being able to identify such unmapped LUNs andreclaim the disk space uselessly consumed by these LUNs will help administrators avoid unnecessaryupgrades and extensions of their disk arrays

56Reporting a Disk Space Consumption

BMC Performance Manager Express for EMC Disk Arrays

Version 2001

Reporting a Disk SpaceConsumptionMaking sure that a disk array has enough remaining disk space available is critical for severalreasons

middot SAN administrators want to make sure to be able to provision disk space for new servers whenrequested as quickly as possible

middot The disk array itself may need additional disk space for specific features to work properly likeautomatic snapshots mirroring etc

middot If thin provisioning is used the remaining disk space becomes dramatically critical since theinability to allocate additional space to a LUN when requested by the subscriber host will lead tocatastrophic data loss and corruption

The disk space used is permanently monitored for each storage pool The Subscribed Capacityparameter of the Pool class represents the amount of disk space that has been made available tothe subscriber hosts or in other words the amount of disk space that is seen by the serversconnected to disk array

The Consumed Capacity parameter of the SEN_EMC_STORAGEPOOLS class represents the actualspace usage in the storage pool For thin pools (when thin provisioning is enabled on the disk array)this value is normally lower than the Subscribed Capacity as it is the main purpose of thinprovisioning For traditional pools the Consumed Capacity parameters has the same value as theSubscribed Capacity parameter as the entirety of the subscribed disk space is fully allocated inthe storage pool

The Consumed Capacity Percentage parameter is the most critical one as a storage pool usagenearing 100 means that SAN administrators will not be able to create new LUNs in the storagepool By default no alarm or warning threshold is set on this parameter as the fullness of a storagepool may be a normal situation However you can set alert thresholds on this parameter as it fitsyour needs

57Reporting a Disk Space Consumption

BMC Performance Manager Express for EMC Disk Arrays

Version 2001

Verifying the Available Disk Space in the Storage Pool of your EMC DiskArrays

1 In the Configure tab select an element group in the tree view (the main ldquoInfrastructurerdquogroup for example)

2 Click on the Reports tab

3 Create a report for the last 24 hours top 50 values of the Array|Storage Pools|Disk Group|Storage Pool|Consumed Capacity Percentage parameter of the EMC Disk Arraysapplication class for the BMC Performance Manager Express for EMC Disk Arrays by SentrySoftware solution

Report ndash Disk Space Consumption

Reporting the Total Traffic on anHourly or Daily BasisBMC Performance Manager Express for EMC Disk Arrays not only monitors the traffic and activity ofthe disk array controllers LUNs and physical disks in MBsec but also in GB per hour or per day Theexact amount of data that was read or written to the disk array LUN or physical disk is calculated foreach hour of the day and each day of the week

Each data rate parameter in MBsec is accompanied by a non-rate one in GB These parameters areldquocumulativerdquo their instantaneous value has no meaning and they need to be visualized in a longperiod of time (instead of Read Byte Rate or Write Byte Rate)

58Reporting the Total Traffic on an Hourly orDaily Basis

BMC Performance Manager Express for EMC Disk Arrays

Version 2001

Generating a Disk Array Usage Report

1 Click the Status tab in Portal

2 When viewing the status of the disk array controller LUN or physical disk click on the graphicon of the Read Bytes or Write Bytes parameter

Setting thresholds

Whenever relevant BMC Performance Manager Express for EMC Disk Arrays automatically setsthresholds for parameters If you prefer a more fault-tolerant monitoring you can modify thethresholds of each parameter through the Configure tab gt Edit Thresholds

It is strongly recommended to wait for all the storage objects to be discovered before setting threshold values to avoidhaving to enter thresholds for each occurrence of the application class

To modify the parameter thresholds of several storage objects of an element

60Setting thresholds

BMC Performance Manager Express for EMC Disk Arrays

Version 2001

1 In the Configure tab click on the Storage (ltplatformgt) or the instance icon gt Edit

Thresholds Properties and Credentials

Any modification to the thresholds or any other properties of elements created using the Element

Profile mode is to be done using the Element Profile route or by clicking Override Profile

2 Uncheck the Warning and Alarm boxes for all the parameters for which you want to disablethe alert conditions

3 Check the Warning and Alarm boxes for all the parameters for which you want to enable thealert conditions You will then have to manually enter the threshold values and check the Activebox In the example below a Warning will be triggered if Status is greater than 1 an alarm willbe triggered when greater than 2

Modifying threshold values

4 Click Save

5 The Success changes have been saved message indicates that the modifications have beenregistered

Alerts are displayed by the parameter whose thresholds are modified

Viewing the Overall Activity of aDisk ArrayIn order to visualize the activity of a disk array use the Read Byte Rate and Write Byte Rate ofthe SEN_EMC_ARRAY class These parameters represent the overall traffic in megabytes per secondfor each monitored array or more precisely each EMC disk array that is exposed through the EMCSMI-S Provider (see the EMC_SMI-S_Provider section of the Installation Guide for more informationabout the EMC SMI-S Provider)

62Viewing the Overall Activity of a Disk Array

BMC Performance Manager Express for EMC Disk Arrays

55Monitoring the Efficiency of the CachingMechanism

BMC Performance Manager Express for EMC Disk Arrays

Version 2001

Comparing W rite Flush Byte Rate w ith W rite Byte Rate

The Cache Dirty Pages Percentage parameter represents the amount in percentage of the writecache that has been modified by host write operations and not yet flushed to the disks Reaching100 means that write case is too small and cannot handle the flow of write operations

Checking the Cache Dirty Pages Percentage

Reclaiming Space of Unmapped(Unused) LUNsOver time as servers connected to a SAN get decommissioned administrators find an increasingnumber of unmapped LUNs or volumes that are no longer used by any server These LUNs whileunused still occupy disk space in the disk array Being able to identify such unmapped LUNs andreclaim the disk space uselessly consumed by these LUNs will help administrators avoid unnecessaryupgrades and extensions of their disk arrays

56Reporting a Disk Space Consumption

BMC Performance Manager Express for EMC Disk Arrays

Version 2001

Reporting a Disk SpaceConsumptionMaking sure that a disk array has enough remaining disk space available is critical for severalreasons

middot SAN administrators want to make sure to be able to provision disk space for new servers whenrequested as quickly as possible

middot The disk array itself may need additional disk space for specific features to work properly likeautomatic snapshots mirroring etc

middot If thin provisioning is used the remaining disk space becomes dramatically critical since theinability to allocate additional space to a LUN when requested by the subscriber host will lead tocatastrophic data loss and corruption

The disk space used is permanently monitored for each storage pool The Subscribed Capacityparameter of the Pool class represents the amount of disk space that has been made available tothe subscriber hosts or in other words the amount of disk space that is seen by the serversconnected to disk array

The Consumed Capacity parameter of the SEN_EMC_STORAGEPOOLS class represents the actualspace usage in the storage pool For thin pools (when thin provisioning is enabled on the disk array)this value is normally lower than the Subscribed Capacity as it is the main purpose of thinprovisioning For traditional pools the Consumed Capacity parameters has the same value as theSubscribed Capacity parameter as the entirety of the subscribed disk space is fully allocated inthe storage pool

The Consumed Capacity Percentage parameter is the most critical one as a storage pool usagenearing 100 means that SAN administrators will not be able to create new LUNs in the storagepool By default no alarm or warning threshold is set on this parameter as the fullness of a storagepool may be a normal situation However you can set alert thresholds on this parameter as it fitsyour needs

57Reporting a Disk Space Consumption

BMC Performance Manager Express for EMC Disk Arrays

Version 2001

Verifying the Available Disk Space in the Storage Pool of your EMC DiskArrays

1 In the Configure tab select an element group in the tree view (the main ldquoInfrastructurerdquogroup for example)

2 Click on the Reports tab

3 Create a report for the last 24 hours top 50 values of the Array|Storage Pools|Disk Group|Storage Pool|Consumed Capacity Percentage parameter of the EMC Disk Arraysapplication class for the BMC Performance Manager Express for EMC Disk Arrays by SentrySoftware solution

Report ndash Disk Space Consumption

Reporting the Total Traffic on anHourly or Daily BasisBMC Performance Manager Express for EMC Disk Arrays not only monitors the traffic and activity ofthe disk array controllers LUNs and physical disks in MBsec but also in GB per hour or per day Theexact amount of data that was read or written to the disk array LUN or physical disk is calculated foreach hour of the day and each day of the week

Each data rate parameter in MBsec is accompanied by a non-rate one in GB These parameters areldquocumulativerdquo their instantaneous value has no meaning and they need to be visualized in a longperiod of time (instead of Read Byte Rate or Write Byte Rate)

58Reporting the Total Traffic on an Hourly orDaily Basis

BMC Performance Manager Express for EMC Disk Arrays

Version 2001

Generating a Disk Array Usage Report

1 Click the Status tab in Portal

2 When viewing the status of the disk array controller LUN or physical disk click on the graphicon of the Read Bytes or Write Bytes parameter

Setting thresholds

Whenever relevant BMC Performance Manager Express for EMC Disk Arrays automatically setsthresholds for parameters If you prefer a more fault-tolerant monitoring you can modify thethresholds of each parameter through the Configure tab gt Edit Thresholds

It is strongly recommended to wait for all the storage objects to be discovered before setting threshold values to avoidhaving to enter thresholds for each occurrence of the application class

To modify the parameter thresholds of several storage objects of an element

60Setting thresholds

BMC Performance Manager Express for EMC Disk Arrays

Version 2001

1 In the Configure tab click on the Storage (ltplatformgt) or the instance icon gt Edit

Thresholds Properties and Credentials

Any modification to the thresholds or any other properties of elements created using the Element

Profile mode is to be done using the Element Profile route or by clicking Override Profile

2 Uncheck the Warning and Alarm boxes for all the parameters for which you want to disablethe alert conditions

61Setting thresholds

BMC Performance Manager Express for EMC Disk Arrays

Version 2001

3 Check the Warning and Alarm boxes for all the parameters for which you want to enable thealert conditions You will then have to manually enter the threshold values and check the Activebox In the example below a Warning will be triggered if Status is greater than 1 an alarm willbe triggered when greater than 2

Modifying threshold values

4 Click Save

5 The Success changes have been saved message indicates that the modifications have beenregistered

Alerts are displayed by the parameter whose thresholds are modified

Viewing the Overall Activity of aDisk ArrayIn order to visualize the activity of a disk array use the Read Byte Rate and Write Byte Rate ofthe SEN_EMC_ARRAY class These parameters represent the overall traffic in megabytes per secondfor each monitored array or more precisely each EMC disk array that is exposed through the EMCSMI-S Provider (see the EMC_SMI-S_Provider section of the Installation Guide for more informationabout the EMC SMI-S Provider)

62Viewing the Overall Activity of a Disk Array

BMC Performance Manager Express for EMC Disk Arrays

Version 2001

Viewing a Disk Array Activity

1 Click the Status tab in Portal

2 Click the array icon in the tree view to visualize its current activity

Selecting a Disk Array Parameter

63Viewing the Overall Activity of a Disk Array

BMC Performance Manager Express for EMC Disk Arrays

Version 2001

3 Click the Read Byte Rate or the Write Byte Rate graph icons to visualize the activity of thedisk array in the past hours or days

Disk Array ReadW rite Byte Rate Graph

The overall activity can also be reported in GB per hour or per day (instead of MBsec) so SANadministrators can visualize how much data has been written to or read off the disk array each hourof the day or each day of the week (see the Reporting the total traffic on an hourly or daily basissection for more information on this subject)

56Reporting a Disk Space Consumption

BMC Performance Manager Express for EMC Disk Arrays

Version 2001

Reporting a Disk SpaceConsumptionMaking sure that a disk array has enough remaining disk space available is critical for severalreasons

middot SAN administrators want to make sure to be able to provision disk space for new servers whenrequested as quickly as possible

middot The disk array itself may need additional disk space for specific features to work properly likeautomatic snapshots mirroring etc

middot If thin provisioning is used the remaining disk space becomes dramatically critical since theinability to allocate additional space to a LUN when requested by the subscriber host will lead tocatastrophic data loss and corruption

The disk space used is permanently monitored for each storage pool The Subscribed Capacityparameter of the Pool class represents the amount of disk space that has been made available tothe subscriber hosts or in other words the amount of disk space that is seen by the serversconnected to disk array

The Consumed Capacity parameter of the SEN_EMC_STORAGEPOOLS class represents the actualspace usage in the storage pool For thin pools (when thin provisioning is enabled on the disk array)this value is normally lower than the Subscribed Capacity as it is the main purpose of thinprovisioning For traditional pools the Consumed Capacity parameters has the same value as theSubscribed Capacity parameter as the entirety of the subscribed disk space is fully allocated inthe storage pool

The Consumed Capacity Percentage parameter is the most critical one as a storage pool usagenearing 100 means that SAN administrators will not be able to create new LUNs in the storagepool By default no alarm or warning threshold is set on this parameter as the fullness of a storagepool may be a normal situation However you can set alert thresholds on this parameter as it fitsyour needs

57Reporting a Disk Space Consumption

BMC Performance Manager Express for EMC Disk Arrays

Version 2001

Verifying the Available Disk Space in the Storage Pool of your EMC DiskArrays

1 In the Configure tab select an element group in the tree view (the main ldquoInfrastructurerdquogroup for example)

2 Click on the Reports tab

3 Create a report for the last 24 hours top 50 values of the Array|Storage Pools|Disk Group|Storage Pool|Consumed Capacity Percentage parameter of the EMC Disk Arraysapplication class for the BMC Performance Manager Express for EMC Disk Arrays by SentrySoftware solution

Report ndash Disk Space Consumption

Reporting the Total Traffic on anHourly or Daily BasisBMC Performance Manager Express for EMC Disk Arrays not only monitors the traffic and activity ofthe disk array controllers LUNs and physical disks in MBsec but also in GB per hour or per day Theexact amount of data that was read or written to the disk array LUN or physical disk is calculated foreach hour of the day and each day of the week

Each data rate parameter in MBsec is accompanied by a non-rate one in GB These parameters areldquocumulativerdquo their instantaneous value has no meaning and they need to be visualized in a longperiod of time (instead of Read Byte Rate or Write Byte Rate)

58Reporting the Total Traffic on an Hourly orDaily Basis

BMC Performance Manager Express for EMC Disk Arrays

Version 2001

Generating a Disk Array Usage Report

1 Click the Status tab in Portal

2 When viewing the status of the disk array controller LUN or physical disk click on the graphicon of the Read Bytes or Write Bytes parameter

Setting thresholds

Whenever relevant BMC Performance Manager Express for EMC Disk Arrays automatically setsthresholds for parameters If you prefer a more fault-tolerant monitoring you can modify thethresholds of each parameter through the Configure tab gt Edit Thresholds

It is strongly recommended to wait for all the storage objects to be discovered before setting threshold values to avoidhaving to enter thresholds for each occurrence of the application class

To modify the parameter thresholds of several storage objects of an element

60Setting thresholds

BMC Performance Manager Express for EMC Disk Arrays

Version 2001

1 In the Configure tab click on the Storage (ltplatformgt) or the instance icon gt Edit

Thresholds Properties and Credentials

Any modification to the thresholds or any other properties of elements created using the Element

Profile mode is to be done using the Element Profile route or by clicking Override Profile

2 Uncheck the Warning and Alarm boxes for all the parameters for which you want to disablethe alert conditions

Disabling the default alert thresholds

61Setting thresholds

BMC Performance Manager Express for EMC Disk Arrays

Version 2001

3 Check the Warning and Alarm boxes for all the parameters for which you want to enable thealert conditions You will then have to manually enter the threshold values and check the Activebox In the example below a Warning will be triggered if Status is greater than 1 an alarm willbe triggered when greater than 2

Modifying threshold values

4 Click Save

5 The Success changes have been saved message indicates that the modifications have beenregistered

Alerts are displayed by the parameter whose thresholds are modified

Viewing the Overall Activity of aDisk ArrayIn order to visualize the activity of a disk array use the Read Byte Rate and Write Byte Rate ofthe SEN_EMC_ARRAY class These parameters represent the overall traffic in megabytes per secondfor each monitored array or more precisely each EMC disk array that is exposed through the EMCSMI-S Provider (see the EMC_SMI-S_Provider section of the Installation Guide for more informationabout the EMC SMI-S Provider)

62Viewing the Overall Activity of a Disk Array

BMC Performance Manager Express for EMC Disk Arrays

Version 2001

Viewing a Disk Array Activity

1 Click the Status tab in Portal

2 Click the array icon in the tree view to visualize its current activity

Selecting a Disk Array Parameter

63Viewing the Overall Activity of a Disk Array

BMC Performance Manager Express for EMC Disk Arrays

Version 2001

3 Click the Read Byte Rate or the Write Byte Rate graph icons to visualize the activity of thedisk array in the past hours or days

Disk Array ReadW rite Byte Rate Graph

The overall activity can also be reported in GB per hour or per day (instead of MBsec) so SANadministrators can visualize how much data has been written to or read off the disk array each hourof the day or each day of the week (see the Reporting the total traffic on an hourly or daily basissection for more information on this subject)

BMC Performance Manager Express for EMC Disk Arrays

Version 2001

Verifying the Available Disk Space in the Storage Pool of your EMC DiskArrays

1 In the Configure tab select an element group in the tree view (the main ldquoInfrastructurerdquogroup for example)

2 Click on the Reports tab

3 Create a report for the last 24 hours top 50 values of the Array|Storage Pools|Disk Group|Storage Pool|Consumed Capacity Percentage parameter of the EMC Disk Arraysapplication class for the BMC Performance Manager Express for EMC Disk Arrays by SentrySoftware solution

Report ndash Disk Space Consumption

Reporting the Total Traffic on anHourly or Daily BasisBMC Performance Manager Express for EMC Disk Arrays not only monitors the traffic and activity ofthe disk array controllers LUNs and physical disks in MBsec but also in GB per hour or per day Theexact amount of data that was read or written to the disk array LUN or physical disk is calculated foreach hour of the day and each day of the week

Each data rate parameter in MBsec is accompanied by a non-rate one in GB These parameters areldquocumulativerdquo their instantaneous value has no meaning and they need to be visualized in a longperiod of time (instead of Read Byte Rate or Write Byte Rate)

58Reporting the Total Traffic on an Hourly orDaily Basis

BMC Performance Manager Express for EMC Disk Arrays

Version 2001

Generating a Disk Array Usage Report

1 Click the Status tab in Portal

2 When viewing the status of the disk array controller LUN or physical disk click on the graphicon of the Read Bytes or Write Bytes parameter

Disk Array Read Byte Graph

Setting thresholds

Whenever relevant BMC Performance Manager Express for EMC Disk Arrays automatically setsthresholds for parameters If you prefer a more fault-tolerant monitoring you can modify thethresholds of each parameter through the Configure tab gt Edit Thresholds

It is strongly recommended to wait for all the storage objects to be discovered before setting threshold values to avoidhaving to enter thresholds for each occurrence of the application class

To modify the parameter thresholds of several storage objects of an element

60Setting thresholds

BMC Performance Manager Express for EMC Disk Arrays

Version 2001

1 In the Configure tab click on the Storage (ltplatformgt) or the instance icon gt Edit

Thresholds Properties and Credentials

Any modification to the thresholds or any other properties of elements created using the Element

Profile mode is to be done using the Element Profile route or by clicking Override Profile

2 Uncheck the Warning and Alarm boxes for all the parameters for which you want to disablethe alert conditions

Disabling the default alert thresholds

61Setting thresholds

BMC Performance Manager Express for EMC Disk Arrays

Version 2001

3 Check the Warning and Alarm boxes for all the parameters for which you want to enable thealert conditions You will then have to manually enter the threshold values and check the Activebox In the example below a Warning will be triggered if Status is greater than 1 an alarm willbe triggered when greater than 2

Modifying threshold values

4 Click Save

5 The Success changes have been saved message indicates that the modifications have beenregistered

Alerts are displayed by the parameter whose thresholds are modified

Viewing the Overall Activity of aDisk ArrayIn order to visualize the activity of a disk array use the Read Byte Rate and Write Byte Rate ofthe SEN_EMC_ARRAY class These parameters represent the overall traffic in megabytes per secondfor each monitored array or more precisely each EMC disk array that is exposed through the EMCSMI-S Provider (see the EMC_SMI-S_Provider section of the Installation Guide for more informationabout the EMC SMI-S Provider)

62Viewing the Overall Activity of a Disk Array

BMC Performance Manager Express for EMC Disk Arrays

Version 2001

Viewing a Disk Array Activity

1 Click the Status tab in Portal

2 Click the array icon in the tree view to visualize its current activity

Selecting a Disk Array Parameter

63Viewing the Overall Activity of a Disk Array

BMC Performance Manager Express for EMC Disk Arrays

Version 2001

3 Click the Read Byte Rate or the Write Byte Rate graph icons to visualize the activity of thedisk array in the past hours or days

Disk Array ReadW rite Byte Rate Graph

The overall activity can also be reported in GB per hour or per day (instead of MBsec) so SANadministrators can visualize how much data has been written to or read off the disk array each hourof the day or each day of the week (see the Reporting the total traffic on an hourly or daily basissection for more information on this subject)

Setting thresholds

Whenever relevant BMC Performance Manager Express for EMC Disk Arrays automatically setsthresholds for parameters If you prefer a more fault-tolerant monitoring you can modify thethresholds of each parameter through the Configure tab gt Edit Thresholds

It is strongly recommended to wait for all the storage objects to be discovered before setting threshold values to avoidhaving to enter thresholds for each occurrence of the application class

To modify the parameter thresholds of several storage objects of an element

60Setting thresholds

BMC Performance Manager Express for EMC Disk Arrays

Version 2001

1 In the Configure tab click on the Storage (ltplatformgt) or the instance icon gt Edit

Thresholds Properties and Credentials

Any modification to the thresholds or any other properties of elements created using the Element

Profile mode is to be done using the Element Profile route or by clicking Override Profile

2 Uncheck the Warning and Alarm boxes for all the parameters for which you want to disablethe alert conditions

Disabling the default alert thresholds

61Setting thresholds

BMC Performance Manager Express for EMC Disk Arrays

3 Check the Warning and Alarm boxes for all the parameters for which you want to enable thealert conditions You will then have to manually enter the threshold values and check the Activebox In the example below a Warning will be triggered if Status is greater than 1 an alarm willbe triggered when greater than 2

Modifying threshold values

4 Click Save

5 The Success changes have been saved message indicates that the modifications have beenregistered

Alerts are displayed by the parameter whose thresholds are modified

Viewing the Overall Activity of aDisk ArrayIn order to visualize the activity of a disk array use the Read Byte Rate and Write Byte Rate ofthe SEN_EMC_ARRAY class These parameters represent the overall traffic in megabytes per secondfor each monitored array or more precisely each EMC disk array that is exposed through the EMCSMI-S Provider (see the EMC_SMI-S_Provider section of the Installation Guide for more informationabout the EMC SMI-S Provider)

62Viewing the Overall Activity of a Disk Array

BMC Performance Manager Express for EMC Disk Arrays

Version 2001

Viewing a Disk Array Activity

1 Click the Status tab in Portal

2 Click the array icon in the tree view to visualize its current activity

Selecting a Disk Array Parameter

Setting thresholds

Whenever relevant BMC Performance Manager Express for EMC Disk Arrays automatically setsthresholds for parameters If you prefer a more fault-tolerant monitoring you can modify thethresholds of each parameter through the Configure tab gt Edit Thresholds

It is strongly recommended to wait for all the storage objects to be discovered before setting threshold values to avoidhaving to enter thresholds for each occurrence of the application class

To modify the parameter thresholds of several storage objects of an element

60Setting thresholds

BMC Performance Manager Express for EMC Disk Arrays

Version 2001

1 In the Configure tab click on the Storage (ltplatformgt) or the instance icon gt Edit

Thresholds Properties and Credentials

Any modification to the thresholds or any other properties of elements created using the Element

Profile mode is to be done using the Element Profile route or by clicking Override Profile

2 Uncheck the Warning and Alarm boxes for all the parameters for which you want to disablethe alert conditions
