EMC® DiskXtender® is a storage management system that provides support for multiple media types, flexible data organization, and rules-based file migration. The MediaStor™ component of DiskXtender is a remote storage solution that provides transparent hardware control and support for a variety of media and device types.

Typically, users on the network save data to a drive on a Microsoft Windows file server. If EMC DiskXtender File System Manager is installed on the file server, File System Manager can migrate files to media in devices attached to a computer where MediaStor is installed. MediaStor receives requests from File System Manager for pieces of media in devices and retrieves media within a device according to those requests.

MediaStor enables you to leverage an existing hardware configuration or create a new one. The EMC DiskXtender Installation Guide provides additional information on planning a DiskXtender system.

The following sections identify key concepts that are central to understanding how to use MediaStor.

Introduction

Role of a media service in remote storageMedia services provide access to media. MediaStor was designed for use with File System Manager, which provides file migration services. MediaStor manages devices by sending commands to the robotics within hardware devices on behalf of File System Manager.

For example, a File System Manager server stores files to media in an optical library managed by MediaStor. When a File System Manager server requests a piece of media so it can write files to or retrieve files from that media, MediaStor sends commands to the library that cause the robotic arm for the library to move to the shelf where the piece of media is located. The robotic arm picks up the piece of media and inserts it in a drive for use by File System Manager.

Introduction

MediaStor conceptsThe following concepts are integral to understanding MediaStor:

◆ “Storage devices” on page 11

◆ “Media types” on page 12

◆ “System management” on page 12

Storage devices Storage devices are hardware devices that enable you to access multiple pieces of high-capacity removable storage media. The addition of a new piece of media can always increase the total storage capacity available through a storage device. Use of a storage device through MediaStor provides you with practically unlimited storage space.

Note: The term device refers to hardware and is used throughout this guide to describe towers, stand-alone drives, and library systems.

MediaStor can manage one or many stand-alone drives, towers, and library devices (system bus resources). The following sections provide more information:

◆ “ Library” on page 11

◆ “ Stand-alone drive” on page 11

◆ “ Tower” on page 11

Library Sometimes referred to as autochangers or jukeboxes, libraries include the following:

◆ Shelves for storing media

◆ One or more drives

◆ Robotic arm that can be controlled by using software to mount and dismount media

MediaStor manages library devices and mounts and dismounts requested media automatically and transparently to the client application. “Libraries” on page 19 provides additional information on adding and managing libraries in MediaStor.

Stand-alone drive Stand-alone drives (internal or external) are nonlibrary drive devices managed by you and MediaStor. You are responsible for mounting and dismounting media in stand-alone drive devices, and MediaStor and the File System Manager servers it services automatically manage the media after the media is in the drive.

When using stand-alone drives, an error appears when you attempt to access datafiles on offline media. The MediaStor alert viewer indicates the media to mount. After the media has been mounted, you can retry the request and retrieve the file.

“Stand-alone drives” on page 41 provides additional information about managing stand-alone drives.

Tower A tower is a case that contains several stand-alone drives. You and MediaStor manage tower devices. You are responsible for mounting and dismounting media in tower drive devices. MediaStor manages the media once the media is mounted in the drives.

MediaStor concepts 11

Introduction

When using tower drives, an error appears when you attempt to access datafiles on offline media. The MediaStor alert viewer indicates the media to mount. After the media has been mounted, you can retry the request and retrieve the file.

“Towers” on page 36 provides additional information about managing towers.

Media types MediaStor supports many high-capacity storage media types. The functionality accessible through a device depends on the type of media used in the device and the file system for which the media is formatted.

The following table defines all media types and file systems that MediaStor currently supports:

After you configure a MediaStor media service and create an extended drive in File System Manager, you can allocate media to that extended drive through MediaStor or through File System Manager. The allocation of media to a File System Manager extended drive makes the media available to the File System Manager service so that you can begin migrating files to and reading files from that piece of media.

Chapter 3, ”Managing Storage Media,” provides information on managing media, including allocating media and viewing media properties.

The EMC DiskXtender Installation Guide provides detailed descriptions of media types and file systems, and the advantages and limitations of using certain file systems.

System management

MediaStor contains several features that enable you to administer, diagnose, and troubleshoot the system, as well as to back up the system and restore it in the event of a system failure. In addition, because the MediaStor program functions as a service, part of the administration of the MediaStor server includes administering the MediaStor service.

Introduction

MediaStor as aservice

MediaStor functions as a Windows service rather than as a user-mode application. As a Windows service, MediaStor can continue to be active even after you log off Windows, as long as the server is still running.

You can start, pause, and stop MediaStor, as well as configure it for various startup settings, including automatic startup, which starts MediaStor upon Windows system startup, and manual startup, which enables you to start the service manually. You can manage the service either through the MediaStor Administrator or through Windows.

“Starting and stopping the service” on page 56 provides additional information.

Logs and reports MediaStor has built-in utilities for monitoring events, errors, and warnings.

◆ The Event Viewer and event logs - The Event Viewer contains a listing of all MediaStor events, errors, and warnings. This information is also logged to event logs. The Event Viewer and event logs can help identify and solve potential problems during runtime that might otherwise become critical problems if ignored. “Monitoring service events, errors, and warnings” on page 60 provides more information on the Event Viewer and event logs.

◆ Reports - The MediaStor reporting feature is a useful tool for tracking system statistics. Use the Report Generator Wizard to create various reports of system activities, including media information, hardware configuration, and MediaStor registry settings. In addition, the reporting function enables you to create and save custom layouts for reports, and to choose the layout when the report is run.

Backup and recovery Because constant and reliable access to data is one of the most critical parts of the system, be sure to have a comprehensive disaster recovery plan ready in the event of system problems or an entire system shutdown.

Use the registry log utility to create a backup of the MediaStor system configuration, which is stored in registry settings. In the event of system failure, you can restore the MediaStor system configuration.

MediaStor concepts 13

Introduction

Starting the AdministratorThe MediaStor Administrator interface enables you to create and configure components, as well as manage server and extended drive properties on one or more MediaStor servers.

The MediaStor Administrator can be run on the same server where MediaStor is installed or from a remote workstation by using the Remote Administrator.

To open the Administrator:

◆ From the Windows Start menu, select Programs > EMC MediaStor > Administrator.

Figure 2 MediaStor Administrator window

When the Administrator opens, it automatically connects to all registered MediaStor servers. If you are using a full version of MediaStor (as opposed to a Remote Administrator), the local server is automatically registered, and therefore automatically appears in the Administrator. After connections have been made, the Administrator displays information relevant to each connected MediaStor service.

Note: To configure MediaStor by using the Administrator, you must be a member of the MSAdministrators group on the MediaStor server.

To administer the MediaStor service on servers other than those currently connected, you must register the MediaStor servers through the Administrator. “Registering a server for remote administration” on page 90 provides more information on registering MediaStor servers.

Managing Hardware

Supported devices and interfacesWhen you add a device to MediaStor, you might need to select it from a list of available devices. MediaStor uses standardized naming conventions for hardware devices. Understanding the format for a device name simplifies identification of the device.

MediaStor supports stand-alone drives, towers, and libraries on the following interfaces:

◆ SCSI

◆ iSCSI

◆ Fibre Channel

◆ IEEE-1394 (FireWire)

All supported devices that are connected to the MediaStor server are listed in the Windows registry. Devices available to configure from MediaStor are automatically listed in the MediaStor Administrator. These devices appear in order according to their model and their device address.

Before you use the MediaStor Administrator to add a library, review the following prerequisites:

◆ Before adding a SCSI device, confirm that the hardware is properly configured. For any SCSI device to work correctly (regardless of its use with MediaStor), all devices and the SCSI adapter must be properly terminated.

◆ Before adding an iSCSI library to a DiskXtender configuration, you must configure an iSCSI HBA or a Microsoft iSCSI Initiator when using a LAN card. “Installing and configuring iSCSI” on page 17 provides instructions.

◆ Before adding a tape library with automatic drive cleaning capability, disable the library’s automatic drive cleaning function.

For a complete list of supported hardware devices, refer to the DiskXtender for Windows Supported Device List available on the EMC Powerlink website.

Device names The SCSI address is the same as the character string that names this device in SCSI Manager. Look at the icon for this device in SCSI Manager. The device name (address) appears in quotes under the icon. More information on SCSI Manager is available in the SCSI Manager Online Help and the EMC DiskXtender File System Manager Administrator’s Guide.

The numbers in the device address represent the SCSI port, bus, target ID, and logical unit ID, respectively. For example, on a typical system with one host adapter, a DVD-R drive or UDO tape drive at target ID 2 would be SCSI.3.0.2.0, where:

◆ 3 is the address of the SCSI port

◆ 0 (first zero) is the bus

◆ 2 is the target ID

◆ 0 (last zero) is the logical unit ID

Managing Hardware

Installing and configuring iSCSI

Before adding an iSCSI library by using the MediaStor Hardware Wizard, you must install and configure an iSCSI HBA or the Microsoft iSCSI Initiator, version 1.6 or 2.0:

◆ To install and configure an iSCSI HBA, use the documentation from the vendor.

◆ To install and configure the Microsoft iSCSI Initiator software, use the procedure, “How to install and configure the Microsoft iSCSI Initiator” on page 17.

You must also configure the port in the iSCSI device or, in some instances, from the front control panel. Usually the port is an RS-232 or LAN port. Refer to the vendor’s documentation for instructions.

The connection between an iSCSI device and the MediaStor server is a point-to-point connection by way of an Ethernet port. The iSCSI device is exclusive to the MediaStor server and cannot be shared by other servers.

If MediaStor is stopped abnormally, the iSCSI device may not receive a release command, and remains in a reserved state by the MediaStor server. This is because the SCSI control program handles errors for the iSCSI device.

To clear a reserve status, use one of the following methods:

◆ From the MediaStor Administrator, right-click the device and select Set Online.

The iSCSI device is reserved by the same initiator again.

◆ Send a release command from SCSI Manager.

◆ Power cycle the iSCSI device.

◆ Restart the MediaStor server to force a bus reset.

How to install and configure the Microsoft iSCSI InitiatorThe following procedure assumes that the library is connected to the MediaStor server.

To install the Microsoft iSCSI Initiator:

1. From the Windows Start menu, select Control Panel > Network Connections.

Note: On Windows 2000, select Start > Settings > Network and Dial-up Connections.

2. Right-click the icon for the LAN port.

LibrariesMediaStor supports a wide variety of SCSI, iSCSI, Fibre Channel and IEEE-1394 libraries.

For a list of supported libraries, refer to the DiskXtender for Windows Supported Device List available on the EMC Powerlink website.

You can add, edit, and remove libraries in the MediaStor system. MediaStor also provides robotics management for libraries which enable you to insert, eject, and move media within the library. MediaStor internally performs all necessary mount and dismount operations for media read/write requests from File System Manager. The following sections provide more information:

◆ “Adding a library” on page 19

◆ “Managing media in a library” on page 29

◆ “Editing a library” on page 32

◆ “Viewing library properties” on page 33

◆ “Setting a library offline” on page 35

◆ “Setting a library online” on page 35

◆ “Deleting a library” on page 36

Adding a library MediaStor treats libraries as single storage devices. An address exists for the library, and for each drive in the library. You can add any supported library currently listed in the Windows registry to MediaStor.

The Hardware Wizard leads you step-by-step through the process of adding a library to MediaStor. You can configure the library at the time you create it, or you can access and change these configurations later through the Hardware Wizard and, in some

Libraries 19


Managing Hardware

cases, through the Properties for the library. The tabs of the Library Properties dialog box are identical to the corresponding pages of the Hardware Wizard.

Note: Before adding a tape library with automatic drive cleaning capability, disable the library’s automatic drive cleaning function.

Note: Before adding an iSCSI library, ensure that an iSCSI HBA or Microsoft iSCSI Initiator has been installed and configured. “Installing and configuring iSCSI” on page 17 provides instructions

The following sections provide instructions on running the Hardware Wizard to add a library to MediaStor:

◆ “Starting the Hardware Wizard” on page 20

◆ “Library Configuration page” on page 21

◆ “Library Drives page” on page 23

◆ “Auto Clean page” on page 26

◆ “Library Options page” on page 27

Starting the HardwareWizard

This section describes how to start the Hardware Wizard and configure the Add New Hardware Device and Select New Library pages.

To add a library:

1. In the MediaStor Administrator, right-click the Hardware node and select New.

The Add New Hardware Device page appears.

Figure 3 Hardware Wizard - Add New Hardware Device page

2. Select Library and click Next.

The Select New Library page appears, listing all of the libraries currently in the Windows registry that have not yet been added to the MediaStor hardware configuration.


Managing Hardware

Figure 4 Hardware Wizard - Select New Library page

3. Select the library to add and click Next.

The Library Configuration page appears.

Library Configurationpage

The Configuration page provides information on the device being added, and enables you to enter a device name and select the drive type (media type) for the library. You can also enable or disable automatic initialization of the library on MediaStor startup.

To configure the Library Configuration page:

1. Type a name for the library. Library names are used only for user interface purposes and can be any alphanumeric string, up to 32 characters.

Figure 5 Hardware Wizard – Library Configuration page

2. From the Drive Type drop-down list, select the type of drive (media) that the library contains.

• If the library is a DVD library that contains different types of DVD drives (including combo drives that function as either DVD-R or DVD-RAM), then the drive type selected for the library determines the following:

– How the drives and the media in the library function.

Libraries 21

Managing Hardware

– Which of the drives and media are read/write or read-only.• If the library is an MO/UDO library that contains both MO and UDO drives,

then the selection of UDO enables you to add both MO and UDO drives to the configuration. The selection of MO restricts you to adding only MO drives to the library configuration.

“Choosing a drive type” on page 22 provides more information for drive types.

3. Select or clear the Set this device online when the server starts checkbox to determine whether this device is set online when the MediaStor service starts.

Note: Do not select this checkbox when you add a library. If the library is online when you test the configuration of the drives in the library (after adding the library and restarting the computer), and if the drives are configured incorrectly, you might encounter hardware problems.

4. Click Next.

The Library Drives page appears. “Library Drives page” on page 23 provides instructions.

Choosing a drive typeThe library type controls the functionality of both the drives and the media in the library. This control pertains specifically to DVD libraries where different types of DVD drives may be installed, and to MO/UDO libraries.

As long as the drives in the library are the same type as the selected drive type, they function as read/write drives. If a drive in the library is of a different type (though still compatible with the library), the drive functions as a read-only drive. If the library contains combo drives, these drives are set to the drive type selected for the library.

In addition, DVD media in the library that is not of the same type as the drive type selected for the library is set to be read-only media during library inventory. For example, if you have DVD-RAM media in the library, but select DVD-R as the drive type for the library, all DVD-RAM media is set as read-only media. The same is true for DVD-R media in a DVD-RAM drive-type library.

For DVD libraries containing combination drives, different drive types or both, all media must be readable in all library drives. For example, if a library contains both DVD-R and DVD-ROM drives, you cannot insert DVD-RAM media into the library because DVD-RAM media is not readable in DVD-ROM drives. In addition, all read/write library media must be both readable and writable in all read/write library drives.

Note: If you are configuring a read-only drive and a write drive in the same library, the two drives should be on separate buses. Be sure to follow all manufacturers recommendations for setting up hardware devices before adding them to MediaStor.

If you will use DVD-R or DVD+R media and keep copies of that media, note that unfinalized media cannot be mounted in a read-only drive. If you intend to update copies of media before the originals are finalized, you must have at least two write drives in the system: one drive for the copy and one for the unfinalized original. This is not an issue if you plan to only update the copy after the original is finalized.

Note: DVD+R media is supported only when used in the PowerFile R200DL DVD libraries. The PowerFile website contains a list of approved DVD media types and manufacturers.


Managing Hardware

For UDO libraries, you can install both UDO and MO drives in the library. MO drives can read/write only to MO media, and UDO drives can read/write to only UDO media. They are not interchangeable due to the differing sector sizes of the media.

In addition, if you select UDO as the library type, you can select both UDO and MO drives during library configuration. Both UDO and MO media can be used in the library. If you select MO as the library type for that same library, you can only select MO drives during library configuration, and only use MO media in the library regardless of the type of drives actually resident in the library.

Library Drives page The Library Drives page of the Hardware Wizard follows the Library Configuration page, which is described in “Library Configuration page” on page 21. When the Library Drives page initially appears, no drives are listed. You must add the drives either automatically or manually.

Managing Hardware

MediaStor enables you to assign certain roles to library drives. This capability is known as drive affinity. When adding drives to the library, you can assign drives to do one or all of the following:

◆ Perform tasks such as formatting and compacting media.

◆ Handle file migration and fetching.

◆ Perform all functions.

To add drives to the library:

1. On the Library Drives page of the Hardware Wizard, select either the automatic or manual method for adding drives:

• Automatic configuration adds all the drives in a library and orders the drives as they exist in the library. To automatically add drives:

a. Click Auto Config.

b. Click Yes to confirm the auto configuration request.

If the automatic configuration is successful, a status message appears. If the automatic configuration fails, a message indicates that you must add the drives manually.

c. Click OK.

The Drives list contains the drives with their corresponding SCSI ID. The drives are usually listed in chronological order from lowest to highest.

• Manual configuration enables you to add the drives manually.

Note: When manually adding drives, you must add them in the order of the drive number and not the SCSI ID. For example, if drive 1 has SCSI ID 1.0.5.0 and drive 2 has SCSI ID 1.0.4.0, the SCSI addresses of the drives do not appear in ascending order. SCSI ID 1.0.5.0 (drive 1) appears before SCSI ID 1.0.4.0 (drive 2). In the Drives drop-down list 1.0.4.0 (drive 2) still appears first.

To add a drive manually:

a. Click Add.

The Select Library Drive(s) page appears, showing all drives currently listed in the Windows registry that are compatible with the drive type selected for the library. The drives are listed as either read/write or read-only drives. The list includes stand-alone drives.

b. Select the drives to add and click OK. Be sure to only select actual library drives. If you select stand-alone or external drives from this page, the configuration test run fails.

2. If you add only some of the drives in a library, add reserved drives as placeholders for the drives that are not added. This is particularly important if the library contains drives that are not compatible with the drive type selected for the library, and therefore cannot be added to the configuration.

Note: Some libraries are configured in a way that there are physically two drives, but the library firmware expects four drives. When Auto Config is used to add drives, reserved drives are added for those bays in the library where the drives are missing.


Managing Hardware

a. Click Add.

The Select Library Drive(s) page appears with a device listed as Reserved.

b. Select the Reserved Device Name entry and click OK.

The Drives page appears with the reserved drive listed.

c. Repeat this process until you have added a reserved drive in the place of each actual library drive that is not being added. The total number of drives, actual and reserved, listed in the Drives page must equal the total number of drives in the library.

3. If you added drives manually, be sure that the library drives, including reserved drives, are defined in the order that the vendor numbers its drive elements. For example, if you have a library with four drives and you are not using the third drive in the library, the reserved drive must appear in place of the third drive in the list.

To change the order of a library drive, select the drive and use the up and down arrows to the right of the Drives list to promote or demote the position of the drive in the list.

4. For each drive listed in the Drives list, do the following:

a. Select a Drive Function:

– All – Select this option to permit all operations including moves, fetches, and other tasks. All is the default value.

– Tasks – Select this option to process transactions and perform tasks such as formatting and compacting media.

– Move/Fetch – Select this option to process transactions, fetches, and moves.

Note: You can configure all drives as either task drives or as move/fetch drives, although doing this is likely to impede performance.

b. Select or clear the Set drive online when library is set online checkbox.

All drives are set online by default. At least one drive must be configured to be set online when the library is set online. Otherwise, the library remains offline.

5. If you added a drive you do not want to use, delete the drive by selecting it and clicking Delete.

Note: If you delete a drive, you might need to add a reserved drive to replace the deleted drive.

Note: If you have a hardware problem with a library drive and want to prevent its use, but do not want to remove the drive from the library configuration, you can temporarily disable the drive by setting it offline. In this situation, you may also want to clear the Set drive online when library is set online checkbox. “Setting a library offline” on page 35 provides more information.

6. Click Next.

One of the following occurs:

• If you are configuring a tape library, the Auto Clean page appears. “Auto Clean page” on page 26 provides more information.

• If you are configuring libraries other than tape libraries, the Options page appears. “Library Options page” on page 27 provides more information.

Libraries 25

Managing Hardware

Auto Clean page The Auto Clean page enables you to set up automatic cleaning options based on read/write usage for tape library drives. Once automatic cleaning is configured, MediaStor initiates automatic drive cleaning without manual intervention.

Figure 7 Hardware Wizard – Auto Clean page

To configure options in the Auto Clean page:

1. Specify an option for Automatic Drive Cleaning Frequency:

• Disable automatic drive cleaning for this library – Select this option to disable automatic cleaning.

• Clean drives when total read/write activity is exceeded – Select this option to initiate automatic cleaning after the specified amount of read and write activity has occurred. In the Total hours of activity [read+write] text box, type the total number of hours the drive must be in use before the drive is cleaned.

• Clean drives when read or write activity is exceeded – Select this option to initiate automatic cleaning after a specified amount of either read or write activity has occurred. In the Total hours of read activity text box, type the number of hours the drive is in use for read activity. In the Total hours of write activity text box, type the number of hours the drive is in use for write activity.

• Clean drives when total mount activity is exceeded – Select this option to initiate automatic cleaning after a specified amount of mount activity has occurred. In the Total mount count text box, type the number of mounts.

• Clean drives when requested by hardware only – Select this option to initiate automatic cleaning after MediaStor receives a cleaning request from the drive.

2. If you enabled automatic cleaning, type the number of shelves in the Shelf numbers reserved for cleaning cartridges text box. The maximum number is eight.

The cleaning cartridge does not need to be physically in the library when configuring automatic cleaning. With the library online, use the Manage Library Media dialog box to insert or eject cleaning cartridges.

IMPORTANT!Do not place the cleaning cartridge in the first shelf of the library. The Test Config function fails if a cleaning cartridge is placed in the first shelf.

3. Click Next.

The Library Options page appears.

Library Options page The Library Options page lists configuration options available for the library.

Figure 8 Hardware Wizard – Library Options page

The configuration options that appear in the lower part of the Library Options page correspond to the option selected in the list in the upper part of the Library Options page.

To configure the Library Options page:

1. Configure the Idle drive dismount (seconds) option:

• Dismount media after – Select this option to enable the library to dismount media from a drive after a certain number of seconds has passed without a read or write request for that media. Type the number of seconds that should pass before the library dismounts the media. The default value is 60 seconds.

• Do not automatically dismount idle media – Select this option to leave media in a drive regardless of how long the media has been inactive. Media is only dismounted when another piece of media must be mounted in the drive for a read or write request.

2. Configure the Maximum shelves to use for inventory option:

• Use all shelves in this library – Select this option to use all of the library shelves to hold media for the media service. This is the default.

• Use only the first __ shelves – Select this option to use a select number of shelves to hold media for the media service. Type the number of consecutive shelves (starting from the first shelf and including the last shelf) that MediaStor should use. This option can be used to partially utilize a library with a damaged shelf or to prevent automatic inventory of a large number of shelves, which can take a long time.

3. Click Finish.

You may be required to restart the computer to enable changes to be made to the configuration.

4. Perform a configuration test after you restart the server to determine if the order of the drives is correct. “Testing the drive configuration” on page 28 provides instructions.

Libraries 27

Managing Hardware

Testing the drive configurationWhen you manually add a library, perform a configuration test on the library to ensure the drives are ordered properly. Automatic configuration should order the drives properly when they are added, but you can perform a configuration test anyway.

To perform a configuration test:

1. Verify that media is present in the library. Media must be present to test the drive configuration.

If the library is a DVD library, ensure that there is no unformatted media in the library. Place a piece of formatted media into the library before running the test.

2. For tape libraries only, verify that the first shelf in the library contains a data cartridge and not a cleaning cartridge.

3. Verify that the library is offline. If the library is online, right-click the library and select Set Offline.

4. Right-click the library and select Modify.

5. Click Yes on the confirmation message.

The Hardware Wizard’s Library Configuration page appears.

6. Click Next to move through the Hardware Wizard until you reach the Library Drives page.

7. Click Test Config.

A warning message appears.

8. Ensure that the first shelf in the library contains valid media and click Yes to continue.

A status message appears while the library and its drives are assessed. After the test is complete, a message appears to indicate whether the test succeeded.

9. Click OK.

10. If the configuration test fails, verify each of the following:

• The drives are ordered properly.

• The number of drives in the library matches the number of drives listed. If any of the drives in the library are not listed, either add the drive manually or add a reserved drive as a placeholder.

• No stand-alone or external drives have been selected.

• There is media in the library. For DVD libraries, ensure there is formatted media in the library. Unformatted media may cause a configuration test to fail.

• There is not a cleaning cartridge in the first shelf in a tape library.

11. Perform another configuration test to ensure accuracy.


Managing Hardware

Managing media in a library

When adding media to a library, certain hardware issues must be addressed. The procedures for adding media are dictated by the specific library being used. Some libraries require that the device be taken offline before inserting media, while other devices allow for media insertion while online.

Library procedures differ by model. For example, some libraries have a mailslot into which media is placed before it is put on a shelf or mounted in a drive. Some libraries use magazines that hold several pieces of media, so that when a magazine is removed, multiple pieces of media are removed as well. Libraries that use magazines must be taken offline before you eject the magazine. After you re-insert the magazine, you can set the library online and it can be inventoried. Always be sure to inventory those shelves where the media status has changed, even if media has been switched on two different shelves.

“Setting a library offline” on page 35 and “Setting a library online” on page 35 provide instructions on setting libraries online and offline.

Quick access to all aspects of library media management is available through the Manage Media feature. Depending on the limitations of the library, you may be able to insert, move, and eject media by using this dialog box. You can also monitor media status.

To manage library media, right-click the library in the Hardware tree and select Manage Media.

The Manage Library Media dialog box appears.

Figure 10 Manage Library Media dialog box

Libraries 29

Managing Hardware

The Manage Library Media dialog box lists the library drives and shelves, along with what media is located on each shelf and the status of the media. Do one of the following:

◆ Insert a piece of media into the library. “Inserting media” on page 30 provides instructions.

◆ Move a piece of media from one library shelf to another. “Moving media” on page 31 provides instructions.

◆ Eject a piece of media from the library. “Ejecting media” on page 32 provides instructions.

Note: Some options may not be available, such as when the library does not support certain commands or has no mailslot. In those cases, the appropriate buttons are dimmed.

Inserting media Some library models have individual procedures for inserting media, such as opening up a door to place media into the shelves. This type of library also requires the library be taken offline while media is inserted, and then set online and inventoried after the media is in place. For information about inserting media into a library, refer to the individual library documentation.

If the library supports it, you can insert media by using the Insert Library Media function.

Note: If you are using a tape library, do not insert a data cartridge into a shelf that is reserved for cleaning cartridges.

To insert media into a library:

1. On the Manage Library Media dialog box, click Insert.

The Insert Library Media dialog box appears.

Figure 11 Insert Library Media dialog box

Note: If specific shelves are selected in the Manage Library Media dialog box when you click Insert, MediaStor automatically enables the Insert media to specified shelves option and enters those shelf numbers in the Shelves text box.

2. Select a method for inserting media:

• Insert media to specified shelves – Select this option to insert media to specific shelves. Type the shelf numbers in the Shelves text box.

• Insert media to first available shelves – Select this option to automatically insert media to available shelves. Type the number of the shelves in the Quantity text box. MediaStor inserts media in the first available shelves.

3. Click OK.

A message similar to the following appears:

Please insert media into the mailslot.

4. Insert the media into the library, and then click OK in the confirmation message dialog box.

MediaStor inserts the cartridge into library shelf.

Note: If the library in use has no mailslot, special considerations apply. The library must be set offline before you manually place media in the shelf or magazine location. After the media is inserted, the library must be set back offline, and MediaStor prompts you to inventory the library. “Setting a library offline” on page 35 and “Setting a library online” on page 35 provide instructions for setting libraries online and offline.

Moving media From the Manage Library Media dialog box, you can move a piece of media from one library shelf to another. The Move feature enables you to optimize system performance by keeping the most frequently used pieces of media closest to the library drives. It also enables you to group media for organization purposes, such as for each department in the workplace.

For tape libraries, you can move a cleaning cartridge to another shelf that is reserved for cleaning cartridges.

To move media in a library:

1. On the Manage Library Media dialog box, click Move.

The Move Library Media dialog box appears.

Figure 12 Move Library Media dialog box

Note: If specific shelves are selected in the Manage Library Media dialog box at the time you click Move, MediaStor automatically enters those shelf numbers in the Move Media On Specified Shelves text box.

2. In the Move Media On Specified Shelves text box, type the numbers of the shelves where the media to be moved are currently located.

3. In the To Empty Shelves Starting At Shelf text box, type the number of the shelf where MediaStor should start to place media.

Managing Hardware

Ejecting media From the Manage Library Media dialog box, you can eject a piece of MediaStor media or some quantity of the least frequently used media from a library. MediaStor continues to track ejected media and prompts you to reinsert the media when read and write requests are received.

Note: If the library in use has no mailslot, special considerations apply. The library must be set offline before you manually remove media from the shelf or magazine location. After the media is removed, the library must be set back online, and MediaStor prompts you to inventory the library. “Setting a library offline” on page 35 and “Setting a library online” on page 35 provide instructions for setting libraries online and offline.

To eject media from a library:

1. On the Manage Library Media dialog box, click Eject.

The Eject Library Media dialog box appears.

Setting a stand-alone drive offline

If a device is experiencing hardware problems or needs to be opened for maintenance or troubleshooting reasons, take it offline. After the problem is corrected, place the device back online. After a drive is offline, it is inactive and you cannot view media statistics, or write to or read from the media.

Stand-alone drives always require the drive be taken offline while media is ejected or inserted. After you insert the media, set the drive online to read the media.

Note: MediaStor does not automatically eject media when set offline. Media must be ejected by using the front panel of the drive.

To set a stand-alone drive offline:

1. Right-click the drive and select Set Offline.


Setting a stand-alone drive onlineA drive must be online for MediaStor to perform media functions that use that drive. For example, stand-alone drives always require the drive be taken offline while media is ejected or inserted. After you insert the media, place the drive online to read the media.

When a drive is set online, MediaStor inventories the media inserted to determine if it recognizes the file format. If the media is unsupported by MediaStor or has been formatted for a file system that MediaStor does not recognize, MediaStor identifies the media as foreign.

To set a stand-alone drive online:

1. Right-click the drive and select Set Online.


Deleting a stand-alone drive

You can delete a stand-alone drive from MediaStor.

After you delete a drive, it is permanently removed from configuration. To use this drive again, you must add it through the Hardware Wizard.

Use caution when you delete a drive. It may be more advantageous to set the drive offline if it is to be used again. This is helpful when a problem occurs with the drive and it is necessary to remove it temporarily from the configuration.

To delete a stand-alone drive from MediaStor:

1. Right-click the drive and select Set Offline.

2. Right-click the drive and select Delete.

3. Click Yes.

You may be required to restart the server to enable changes to be made to the SCSI configuration.

By adding media to the MediaStor hardware devices, you create a supply of storage media that you can allocate for use by connected File System Manager services. Media are listed in the MediaStor system once they are inserted in the device and inventoried.

Media that have been added to the system, but have not yet been allocated to a File System Manager extended drive, appear in the Scratch Pool media tree. Media that have been allocated to a File System Manager extended drive can be found under their specific extended drive node in the Application Pools media tree.

When a piece of media is initially added to a media device, MediaStor evaluates the media and places it in one of the eight nodes in the media tree. Which node it is placed in depends on the media attributes, such as whether the media is formatted with a recognized file system or if the media is not yet labeled.

CAUTION!The presence of duplicate media likely indicates a problem in the system. Contact EMC Customer Service at the EMC Powerlink website.

The following sections deal primarily with accessing information about the media and how to move the media between the Application and Scratch Pools:

◆ Media pools...................................................................................................................... 50◆ Allocating media to application pools ......................................................................... 51◆ Moving media to the Scratch Pool................................................................................ 52◆ Deleting media................................................................................................................. 53

“Monitoring media” on page 68 provides more information on monitoring media in the system.

Managing StorageMedia

Managing Storage Media 49

Managing Storage Media

Media poolsThe MediaStor Administrator lists two media pool trees in the tree view: Scratch Pool and Application Pools. The Scratch Pool tree contains all media in the MediaStor system that is not currently assigned to an application. The Application Pools tree displays all extended drives configured for each File System Manager server that is currently using MediaStor as a media service.

Each application media pool is identified by three characteristics:

◆ Application that is using MediaStor as a media service.

◆ Name of the server where the application is installed.

◆ Extended drive letter.

For example, the name of an application media pool as it appears in the Application Pools tree might be DX_DXD4_I. In this example, DX is the File System Manager application. DXD4 is the name of the File System Manager server. And I is the drive is configured as a File System Manager extended drive. This naming convention enables you to quickly identify where you should assign the media from the Scratch Pool, if you choose to allocate the media through MediaStor. Media can also be allocated through File System Manager.

The media in both the Scratch Pool and the Application Pools are grouped by class:

Table 8 Media classifications

Class Description

Original Media you have prepared for use with MediaStor (formatted and labeled).

Copy Media that are being used as copies of original media. The only difference between an original piece of media and its copy is the serial number for each piece of media.

Duplicate Any media with the same serial number as another piece of media. You cannot use duplicate media with MediaStor. The presence of duplicate media likely indicates a problem in the system. Contact EMC Customer Service for assistance.

Blank Media that you have formatted for use but not yet labeled. Through File System Manager, you can label or reformat blank media, or label it for use as a copy (if the media allows it).

Foreign Media that have been formatted for a file system that is not supported for that media type. You can format foreign media with a supported file system (if MediaStor supports the type of media).

Unknown Media that MediaStor does not recognize. The problem could be an unsupported media type or an unsupported file system.

Unformatted Media that you unpackaged and placed in the device but that you have not yet formatted for the first time. You must format unformatted media to make it blank media, or format and label it to make it original media.

Corrupt UDF-formatted media that the system recognizes but cannot use because of problems with the media itself. Media corruption most often occurs as a result of a power failure while files are being written to the media. Performing a Check Disk media task on the media (through File System Manager) may enable you to find and repair the errors.

Cleaning Cleaning cartridge used for automatic drive cleaning.



Allocating media to application poolsAfter you have configured a MediaStor media service and created an extended drive in File System Manager, you can allocate media to that extended drive by using the Allocate Media to Application Pool feature in MediaStor. The allocation of media to a File System Manager extended drive makes the media available to the File System Manager service so that you can begin migrating files to and reading files from that piece of media.

Note: You can also allocate media to an extended drive through the File System Manager interface. The EMC DiskXtender File System Manager Administrator’s Guide provides instructions.

To allocate media to an application pool:

1. Do one of the following:

• Select the piece of Scratch Pool media to allocate and then drag it to the appropriate application pool.

The media is allocated to the application pool.

• Right-click a piece of Scratch Pool media and then select Allocate Media to Application Pool.

The Allocate Media to Application Media Pools dialog box appears.

Figure 29 Allocate Media to Application Media Pools dialog box

2. From the Application Media Pools drop-down list, select the application pool to which the media will be allocated.

3. Select the media to allocate to that application pool.

4. Click Allocate.

The selected media pool appears to the right of the media in the Media list.

Allocating media to application pools 51


Figure 30 Allocate Media to Application Media Pools dialog box

5. Repeat steps 2 through 4 for any remaining media to be allocated to an application pool.

If you allocate media to an application pool incorrectly, select the media and click Deallocate.

6. Click OK.

In the tree view, the selected media is moved to the appropriate application pools.

In File System Manager, the media appears under the Original media node for the extended drive.

Moving media to the Scratch PoolYou can remove a piece of media from an application pool, such as a File System Manager extended drive, from either File System Manager Administrator or from MediaStor Administrator.

◆ Within File System Manager Administrator, you deallocate the media.

◆ Within MediaStor Administrator, you move the media back to the Scratch Pool.

The EMC DiskXtender File System Manager Administrator’s Guide provides instructions on deallocating media in File System Manager.

To move media to the Scratch Pool:


• Select the piece of application pool media to move, and drag it to the Scratch Pool.

• Right-click the piece of application pool media to move to the Scratch Pool, and then select Move Media to Scratch Pool.

A warning message appears to remind you that after media is removed, the media is no longer available to the application.

2. Click Yes to remove the media from the application pool and place it in the Scratch Pool.



Deleting mediaYou can delete Scratch Pool media from MediaStor so that you can remove the media from the hardware device.

To delete media from media pools:

1. Move the media to be deleted to the Scratch Pool. “Moving media to the Scratch Pool” on page 52 provides instructions.

2. Set the hardware device offline by right-clicking the device and selecting Set Offline.

3. Right-click the media and select Delete.


5. Remove the media from the hardware device.

If you do not remove the media from the hardware device after you delete it, it reappears in the Scratch Pool the next time you inventory the device.

6. Set the hardware device back online by right-clicking the device and selecting Set Online.

Service Management

Starting and stopping the serviceMediaStor functions as a Windows service rather than as a user-mode application. As such, the MediaStor service can continue to be active even after you log off Windows, as long as the server is still running.

If necessary, you can pause, stop, and restart the MediaStor service. You can also configure whether the service starts automatically upon Windows system startup.

CAUTION!The service continues to run as long as the server is running. If you plan to shut down the MediaStor server, stop the MediaStor service before doing so. This enables the service to complete whatever function it was performing before the system shuts down. In cases where DiskXtender is writing a file to media, stopping the service before shutting down the server reduces the possibility of file write and/or media errors occurring during shutdown.

You can stop, start, and edit automatic startup for the service by using either the MediaStor Administrator or the Services and Applications option in the Windows Administrative Tools console. The MediaStor service is called "EMC MediaStor" in the Windows Services and Applications list.

Note: You must be a member of both the local Administrators group and the MSAdministrators group on the MediaStor server to manage the service.

To stop, pause, or restart the service:

1. From the Computer drop-down list in the MediaStor Administrator, select the server to manage.

2. From the Tools menu, select Service Manager.

The Service Manager dialog box appears.

Figure 31 Service Manager dialog box

3. Stop, pause, or start the service as necessary by double-clicking the corresponding option.

6. Select a startup type:

• Automatic – Select this option to start the service every time the Windows system starts. This is the default.

• Manual – Select this option to start the service by a user or by a dependent service.

• Disabled – Select this option to prevent the service from starting until the startup type is changed to Automatic or Manual.

7. Click OK.

8. Click Close.

Editing the service accountYou can edit the username and password for the service account. The service account, which MediaStor uses to log on to the server, is the account specified during installation.

Note: The service account must have the Log on as a service privilege. This privilege is automatically assigned to the account entered during installation. However, to change the service account, add this privilege to the new account if it does not already have the privilege.

Note: You must be a member of both the local Administrators group and the MSAdministrators group on the MediaStor server to manage the service.

To edit the service account:

1. From the Computer drop-down list in the MediaStor Administrator, select the server to manage.

2. From the Tools menu, select Service Manager.

3. Click Edit Service Settings.

In the Log On As section, the This Account option is enabled by default and contains the username and password that was entered during the MediaStor installation.

Monitoring the System 59


Monitoring service events, errors, and warningsMediaStor has built-in utilities for monitoring events, errors, and warnings within the system. The Event Viewer contains a listing of all MediaStor events, errors, and warnings. This information is also logged to event logs. Errors and warnings are logged automatically, while MediaStor must be configured to log other events.

The Event Viewer and event logs provide a quick look at the activities of MediaStor. Logs can help identify and solve potential problems during runtime that might otherwise become critical problems if ignored. You can also look up errors you find in the logs, and configure event logging. If the Event Viewer and event logs become too large and cumbersome to navigate, you can clear them.

You can also configure automatic notification of warnings and errors by setting up alerts.


◆ “Using the Event Viewer” on page 60

◆ “Using event logs” on page 60

◆ “Sending alerts for errors and warnings” on page 61

◆ “Looking up errors” on page 63

◆ “Configuring event logging” on page 64

◆ “Clearing the Event Viewer and event logs” on page 67

Using the Event Viewer

The Event Viewer displays all events for the MediaStor service. If you do not want to automatically save a record of the events on the MediaStor server, you can disable event logging in the Service Event Configuration dialog box and simply monitor events in the Event Viewer. “Configuring event logging” on page 64 provides more information on disabling event logging.

To open the Event Viewer, open the Service menu and select Event Viewer.

You can also take a snapshot of the contents of the Event Viewer and save it for later use. A snapshot captures up to the last 2,048 lines of the Event Viewer.

To take a snapshot of the Event Viewer:

1. From the File menu, select Event Viewer.

2. Select Snapshot.

The snapshot appears in RtfPad. You can save, print, and email the snapshot from RtfPad.

Using event logs In addition to the viewing capabilities offered by the Event Viewer, MediaStor also contains three event logs that save events, errors, and warnings for the MediaStor server to log files.

Errors and warnings also appear in the Event Viewer, but the Errors Only Log and Warnings Only Log provide a more precise focus on these important events. You can also configure errors and warnings to be sent out as alerts to a specific domain, user, computer, or email address so that you are automatically notified when they occur. “Sending alerts for errors and warnings” on page 61 provides more information.



Because they are necessary for system diagnostics, the logging of errors and warnings cannot be disabled. If technical support is needed, you may be asked to open these logs and specify the information reported.

When opened, the logs decrease MediaStor performance. When closed, the impact they have on performance is insignificant. The logs should be opened and used only for debugging purposes.

Note: Because tracing events impedes system performance, no events are traced by default, though errors and warnings are logged automatically because of their necessity for troubleshooting. “Configuring event logging” on page 64 provides more information.

To view a log:

◆ From the Service menu, select Event Logs, and then select the appropriate log to view. Choose from All Events, Warnings Only, or Errors Only.

The selected log appears in RtfPad.

The log displays the time and a message for each event. The most recent events are last on the list. (The list automatically scrolls to display the most current events.)

You can save, print, and email the log from RtfPad.

All Events log The All Events Log lists all activities on the MediaStor service. Event logging is useful for tracing events of interest to you. You can configure which events are traced.

Errors Only log The Errors Only Log lists only MediaStor system errors and is a useful tool for detecting and diagnosing those errors.

Note: You can use the System Error Lookup feature to obtain additional information about each error, including the error name and description, and to quickly translate error codes that appear in MediaStor. “Looking up errors” on page 63 provides more information.

Warnings Only log The Warnings Only Log lists only MediaStor system warnings to warn you of possible problems in MediaStor, such as requests for media that could not be satisfied because the media was not present in any drive or library. The purpose of this list is to provide a simpler means of discovering where problems exist that are hindering MediaStor performance.

Sending alerts for errors and warnings

An alert is a message box that notifies the recipient of an error or warning on the MediaStor system.

Figure 33 Alert message

Alerts can be sent to a specific user, computer, email address, or domain. They can notify the recipient of warnings, errors, or both.

Monitoring service events, errors, and warnings 61


By default, an alert appears on the MediaStor server when an error or warning occurs. You can edit this alert or add a new one. If necessary, you can also delete an alert.

The Windows Messenger service, which sends DiskXtender alerts, is disabled by default in Windows 2003. To receive DiskXtender alerts, you must start the Messenger service by using the Windows Service Manager.

To open the Windows Service Manager:

1. From the Start menu, select Programs.

2. From the Programs group, select Administrative Tools > Services.

To scroll through the list of system errors, click the arrow buttons.

Configuring event logging

Event logging is necessary only when tracing events of interest. You can configure which events are traced. Because tracing events impedes system performance, no events are traced by default, though errors and warnings are logged automatically because of their necessity for troubleshooting.

MediaStor enables you to configure which events are logged, and whether to trace the local service events or remote procedure calls (remote administration events).

For all logs, you can control the format of the log entries and adjust the maximum sizes for the log files. For the All Events Log, you can disable logging and enable the tracing of events upon startup. You can enable logging to the Windows Application Log for the Warnings Only Log and the Errors Only Log.

Log propertiesconfiguration

You can control several aspects of logging functionality, including log entry format, log file size, event logging, automatic startup of event logging, and logging of errors and warnings to the Windows Application Log.

To configure log properties:

1. From the Service menu, select Event Settings.

The Configuration tab of the Service Event Configuration dialog box appears.



Figure 36 Service Event Configuration dialog box – Configuration tab

2. In the Line Format section, specify which event attributes to log. These options are enabled by default.

• To disable logging the time each event occurs, clear the Time checkbox.

• To disable logging the date each event occurs, clear the Date checkbox.

• To disable logging the thread that the event used to communicate with the processor, clear the Thread ID checkbox.

3. In the Event Log section, configure the All Events Log. Event logging is enabled by default; however, no events are traced. “Event tracing configuration” on page 66 provides more information on selecting events to trace.

• To change the maximum size for the log file, enter a new value in the Maximum Log Size text box. The default size is 5 MB. After the maximum log size is reached, the log is truncated from the beginning of the file (oldest events).

• To disable the All Events Log, select the Disable log file (viewer only) checkbox. Events are still logged to the Event Viewer.

• To automatically initiate event logging when MediaStor is started, select the Trace messages on startup checkbox.

4. In the Warning Log section, configure the Warnings Only Log.


• To enable logging of MediaStor warnings to the Windows Application Log, select the Write to Windows Application Log checkbox. Because MediaStor warning logs are cleared when the service is restarted, this option enables the Windows Application Log to maintain a running log for MediaStor warnings outside of the MediaStor service.

To access the Windows Application Log, open the Start menu and select Programs > Administrative Tools > Event Viewer.



Note: You cannot disable the Warnings Only Log.

5. In the Error Log section, configure the Errors Only Log.


• To enable logging of MediaStor errors to the Windows Application Log, select the Write to Windows Application Log checkbox. Because MediaStor error logs are cleared when the service is restarted, this enables the Windows Application Log to maintain a running log for MediaStor errors outside of the MediaStor service.

Note: You cannot disable the Errors Only Log.


• To begin tracing events, click Apply to save changes and then select the Trace tab. “Event tracing configuration” on page 66 provides more information on tracing events.

• If you are finished configuring log properties, click OK.

Event tracingconfiguration

You can configure which events are traced and reported to the Event Viewer and the All Events Log. By default, all event tracing is disabled. Unless instructed to enable tracing of events by an EMC Customer Support Representative, you can maintain the default settings.

Note: Event tracing configuration affects events only. Errors and warnings which relate to events of the types listed are logged regardless of event tracing settings.

CAUTION!Enabling event tracing hinders performance and should be performed only when debugging is required.

To configure events to be logged:

1. From the Service menu, select Event Settings.

The Service Event Configuration dialog box appears.

2. Click the Trace tab.



Figure 37 Service Event Configuration dialog box – Trace tab

3. From the System drop-down list, select whether to trace System Processing (local computer service events) or Remote Procedure Calls (remote administration service events).

4. In the Options list, select the checkbox next to an event to begin tracing that event.

5. Click OK.

Clearing the Event Viewer and event logsYou can manually clear the information in the Event Viewer and the event logs.

Event logs have a specific size limitation, after which the log is truncated from the beginning of the file. While the log size is regulated through automatic truncation, large logs are often cumbersome and difficult to navigate. “Configuring event logging” on page 64 provides additional information.

Clearing event logs regularly makes it easier to find new information. However, you might want to save the log before clearing it. To save a log, open it and select Save from the File menu.

To clear the Event Viewer or an event log:

1. Open the Service menu, select Event Logs, and then do one of the following:

• To clear the Event Viewer and the All Events Log, select Clear Event Log.

Audit logsAn audit log is a secure log file in MediaStor that functions independently of the existing DiskXtender logs (event and warning logs) and Windows system logs.

The purpose of the audit log is to provide a secure, access-controlled means for monitoring the following:

◆ "Change" events to the MediaStor service

◆ Whether each event succeeds or fails

An audit log enables you to monitor important DiskXtender events, such as:

◆ Addition, editing, and deletion of device management events.

◆ Service stops and starts.

The performance impact caused by audit logging is minimal.

The following sections provide more information on configuring and using audit logs:

◆ “Enabling and configuring audit log settings” on page 74

◆ “Deciding which events to audit” on page 75

◆ “Viewing the audit log” on page 77

◆ “Clearing the audit log” on page 78

◆ “Exporting the audit log” on page 78

◆ “Backing up the audit log” on page 79

Note: You must be a member of the MsSecurityAdmins group on the MediaStor server to view, clear, and export the audit log, and to configure audit log settings.

Enabling and configuring audit log settingsAudit logging is automatically enabled, and the service account is automatically added to the MsSecurityAdmins group during MediaStor installation. However, you can also enable audit logging later by adding a user to the group and performing the steps below.

To enable and configure the audit log:

1. Add the user account you are using to the MsSecurityAdmins group on the MediaStor server.

2. From the Tools menu, select Audit Log.

The Audit Log Configuration Settings dialog box appears.



Figure 43 Audit Log Configuration Settings dialog box

3. Select Enabled to turn on audit logging.

4. In the Max Logfile Size section, choose whether to limit the maximum file size for the audit log.

• To limit the file, type a maximum size in MB. The default is 10 MB.

Note: If the log file reaches its maximum size, a warning message appears and the audit log is disabled. You must either clear the log or increase the maximum file size for the log. Then reenable audit logging.

• To enable an unlimited audit log file size, select Unlimited.

5. In the Audit Log Location section, type the path for where to store the audit log (either a local or UNC path), or click Browse to navigate to and select a location.

If you specified an unlimited file size in step 4, then you should change the default location from the MediaStor installation directory. If the system drive becomes full, the system may crash.

Note: If you change the location of the audit log after audit logging has begun, the old log remains in the original location, but is no longer updated.

6. In the Operations to Audit section, choose the events to audit by selecting or clearing the checkboxes. “Deciding which events to audit” on page 75 provides details.

7. Click OK.

Deciding whichevents to audit

You can choose the events to audit by selecting and clearing the Operations to Audit checkboxes on the Audit Log Configuration Settings dialog box.

The following table provides a description for each event that is logged.

Clearing the audit log

If you are a member of the MsSecurityAdmins group, you can reset the audit log. Resetting the audit log will delete all entries in the audit log. Resetting the log may be useful if you are short on disk space; however, creating a backup of the log before resetting is recommended.

To clear the audit log:

1. Create a backup of the audit log in another location so that you do not permanently lose the log entries.



3. Click Reset.


Exporting the audit log

You can export the data from the audit log to a tab-delimited text file. The data can then be moved into a spreadsheet or database application.

CAUTION!Once you export the data, it is no longer protected by DiskXtender. In other words, users who are not members of the MsSecurityAdmins group can view and edit the information.You must implement other protective measures (such as password protection, available in many spreadsheet applications) to maintain security of the information.

6Invisible Body Tag

Because constant and reliable access to data is one of the most critical parts of the system, you should have a comprehensive disaster recovery plan in place in the event of system problems or an entire system shutdown. MediaStor contains a registry utility that can help you back up and restore the MediaStor configuration, even when the problem is a minor one. The following sections provide more information:

◆ Backing up MediaStor .................................................................................................... 82◆ Restoring MediaStor ....................................................................................................... 86

Backup and Recovery

Backup and Recovery 81

Backup and Recovery

Backing up MediaStorThe MediaStor system configuration is stored in registry settings. A usable backup of these settings can help you recover and restore the system in the event of a MediaStor server crash. This backup is called a registry log.

MediaStor automatically updates the registry log every hour, and saves one registry log per day for each of the last seven days.

◆ MediaStor.rlog — the registry log file with the most recent (hourly) updates

◆ MediaStor_mm_dd_yyyy.rlog — the registry log file for each of the last seven days

Where mm_dd_yyyy represents the date the file was created.

The Registry Log Wizard enables you to do the following:

◆ Change where the registry log is automatically saved

◆ Set a location for a copy of the registry log

◆ Change the number of days that MediaStor retains registry logs (the default is seven days)

◆ Restore MediaStor registry settings


◆ “Changing the registry log location” on page 82

◆ “Retaining versions of the registry log” on page 83

◆ “Copying the registry log file” on page 85

◆ “Restoring MediaStor configuration” on page 86

Changing the registry log locationBy default, MediaStor automatically saves registry log files into a Registry Log folder in the install directory, C:\Program Files\EMC\MediaStor. However, in the event of a system crash, you will likely lose information on the main drive, and therefore lose the registry log files.

The Registry Log Wizard enables you to designate a different location for MediaStor to store the registry log files it creates. To ensure fail-proof disaster recovery, the backup location should be a volume separate from where the Windows server files reside. You might want to save the registry log files to a different server.

In addition, because MediaStor can retain versions of the registry log file from multiple days, you might want to change the location of the automatically saved registry log files for space reasons, depending on the size of the MediaStor registry.


Backup and Recovery

To change the registry log location:

1. From the Tools menu, select Registry Log.

The Registry Log Wizard appears.

Figure 46 Registry Log Wizard – Introduction page

2. Select the Set the automatic registry log location option and then click Next.

The Automatic Registry Log Location page appears.

Figure 47 Registry Log Wizard – Automatic Registry Log Location page

3. Enter or browse to the UNC path to which the registry log should be saved.

4. Click Next.

5. Review the information in the summary, and then click Finish.

Retaining versions of the registry log

MediaStor automatically saves one registry log per day for each of the last seven days. You can change the number of days that MediaStor retains registry logs by using the Registry Log Wizard.

Note: Registry log versioning applies only to the automatically saved registry log files and does not apply to any registry log copies you may make. “Copying the registry log file” on page 85 provides more information on registry log copies.

Backing up MediaStor 83

Backup and Recovery

To set the number of days to retain registry log files:




2. Select Specify how many days to retain registry log images and then click Next.

The Registry Log Image Retention page appears.

Figure 49 Registry Log Wizard – Registry Log Image Retention page

3. Enter the number of days that the registry log files should be kept.

Note: Setting this to zero days disables the versioning function. The original .rlog file is saved and overwritten each time the registry log information is updated, but no previous versions are saved.

4. Click Next.



Backup and Recovery

Copying the registry log file

If necessary, create an additional copy of the current registry settings. The copy is a one-time backup and does not update regularly.

If something happens to the system where the automated registry log files are stored, the primary copies of the registry log file may be unusable for system restoration. Create a manual copy of the registry log regularly to ensure you have a usable copy of the system configuration.

Note: Setting a location for a copy of the current configuration does not affect the location for automatic backup. MediaStor continues to back up MediaStor registry information to the location set for automatic registry log creation.

To copy the current registry log:




2. Select Copy current registry log information to another location and then click Next.

The Copy Registry Log Information page appears.

Figure 51 Registry Log Wizard – Copy Registry Log Information page

3. Enter or browse to a directory path and filename, and then click Next.


Backing up MediaStor 85

Backup and Recovery

Restoring MediaStorIn the event of catastrophic system failure, the same MediaStor utility that enables you to create backups of the registry settings also enables you to restore those backups to the MediaStor system. The restore function for the registry log utility makes recovery and reconfiguration of the system after a disaster both faster and more accurate.

When a system failure or disaster occurs, use the following procedure to most effectively restore the MediaStor system.

To restore a MediaStor system:

1. If necessary, reformat the hard drive on the MediaStor server.

2. Reinstall Windows.

3. If File System Manager is installed on a different server (and is configured to use this MediaStor installation as a media service), stop the DiskXtender service on the File System Manager server.

If you are restoring both File System Manager and MediaStor on this server, proceed to the next step.

4. Reinstall MediaStor. The EMC DiskXtender Installation Guide provides instructions.

5. Restore the registry log (MediaStor registry) file. “Restoring MediaStor configuration” on page 86 provides more information.

6. If File System Manager is installed on a different server (and is configured to use this MediaStor installation as a media service), restart the DiskXtender service on the File System Manager server.

If you are restoring both File System Manager and MediaStor on this server, reinstall File System Manager and then follow the remaining steps in the EMC DiskXtender File System Manager Administrator’s Guide to restore the system.

These steps should be sufficient to get the MediaStor system back up and running after a disaster or system failure. If you run into any problems, contact EMC Customer Service at the EMC Powerlink website for assistance.

Restoring MediaStor configuration

When problems occur on the MediaStor server, you can restore the MediaStor configuration by using the Registry Log Wizard to restore the backup of the registry settings after you have reinstalled all of the necessary software components.

MediaStor updates the registry log file every hour and saves one registry log file for each of the last seven days by default.

◆ MediaStor.rlog — the registry log file with the most recent (hourly) updates

◆ MediaStor_mm_dd_yyyy.rlog — the registry log file for each of the last seven days

Where mm_dd_yyyy represents the date the file was created.

CAUTION!Attempting to restore a registry log file from a version of MediaStor other than the one currently installed will fail. Be sure that you are restoring a registry log file from the same version and build of MediaStor you are currently running.


Backup and Recovery

To restore the registry configuration:




2. Select Restore service configuration from a registry log and click Next.

The Restore Registry Log page appears.

Figure 53 Registry Log Wizard – Restore Registry Log page

3. Enter the directory path and filename for or browse to the registry log file.

When using the Browse function to find the registry log file, select the directory where the registry log files are located and click OK. Then select the registry log file from the Registry Log Images dialog box and click OK.

In most cases, you should select the registry log file named MediaStor.rlog, which has the most recent updates.

However, if the system corruption took place sometime before the most recent registry log file was saved, you might restore an earlier version of the file. In this case, choose the registry log file with the most recent date.
