RecoverPoint 4.1 Implementation and Management


2/50


This course covers how to implement and utilize features and enhancements in RecoverPoint

4.1 such as snap-based replication, external storage integration, enhanced group sets, policy

templates and log collection.

This course is intended for those with a RecoverPoint background who are involved in theimplementation, management, support and troubleshooting of RecoverPoint offerings.



3/50


This module focuses on applying snap-based replication on a given consistency group.

5/50


Once snap-based replication has been configured, replication will transition through two states:

Replicating Snap and Snap Idle. Replicating Snap is displayed when the production site is

replicating to the replica site. The replication status is shown in percentage. Snap Idle is

displayed when the replication is complete and there is no activity, as shown here.Both of these states will be used in periodic mode. If On Highload is applied, only snap

replicating will be used.

In case of an error, RecoverPoint will attempt several retries. If the snap-based replication

mode is set to On Highload, events will be sent to the user and RecoverPoint will resume

regular async replication. If the mode is set to periodic, transfers will be paused and user

intervention will be required.



6/50


This module focuses on the steps necessary to integrate a VNX storage array to a RecoverPoint

Appliance (RPA) cluster for the purpose of automatically creating journal volumes.



7/50


The Storage feature of RPA opens a direct line of communication with the storage array. The

storage array must be a VNX running VNX OE for Block 32 or later. The External Storage wizard

is located within the RPA clusters tab. The Addbutton can be found under the Storage ->

Registered Storagetab.



8/50


Once the storage arrays have been registered, resource pools must be registered next. The RPA

cluster will automatically create a journal volume only if at least one resource pool is

registered.



9/50


Registering your storage array on the RPA cluster provides the capability of automatically

creating journal volumes from the GUI or CLI using array storage pools. The process of creating

a consistency group remains the same, and creating a journal volume can be defined in one of

two ways:(1)Select Provisioned Journal Volumethat uses already-presented volumes to create journal

volumes for replica and production copies

or

(2) Automatically Provision Journal Volumethat creates the journals from a storage pool (or

RAID group) on the storage array.

The volume is created using the default settings in the storage pool.

Click Nextto see a demonstration of Automatic Journal Volume Creation.

11/50


Through the CLI, a storage array can be registered using theregister_storagecommand.

For VNX systems, a type, primary and secondary IPs, and authentication are required for a

successful registration. In this example, a storage named Site4VNX is being registered to

Cluster1 and the cluster returns a message to confirm that the registration was successful.The get_registered_storagecommand provides information on all storage arrays

connected to specified clusters. In this example, we need to get the registered storage

information from Cluster1 and input the cluster name at the prompt. Below Registered Storage

is the listed information about the registered storage, including the connectivity status. The

registered storage can only be used with a connectivity status of OK.



12/50


Before using the registered storage, a resource pool must be registered by using the

register_resource_poolcommand. The storage name and resource pool names are

required. In this example, Pool_0 is being registered to Cluster1 and Pool_0 is on Site4VNX.

After the command has been executed, the cluster returns a message to confirm that theregistration was successful.

The get_resource_poolscommand provides information about all resource pools

registered on a specified cluster and specific storage array. In this example, we want to get

information on resource pools registered to Cluster1. Currently, there is only one storage array

registered to that cluster, so we choose it. There is only one resource pool registered, Pool_0.

The resource pool is listed along with total and available size and supported tiers.



13/50


This module focuses on the creation of policy templates and enhanced group sets.



14/50


To learn the process of creating a Copy template, you will be instructed to click tabs, buttons

and drop-down menu items. The instructions for the remaining steps will appear to the right of

the screen.

If you wish to skip the steps, click the Nextbutton to advance to the Copy Policy Template: CLIpage.

Policy templates allow the administrator to set specific parameters and apply them to a

consistency group efficiently. Create new policies from the Protectiontab.

Click the Protectiontab.



15/50


Click the Policy Templatesoption.



16/50


Click Add.



17/50


Click the Typedrop-down menu button.



18/50


Select the type Copyto create a copy policy template and provide a name.



19/50


Journal compression has three options: none, medium and high. The maximum journal size

capacity is set to unlimited or capped at a specific number.

From the Journal Compression drop-down menu, choose Medium.



20/50


When selected, the Required Protection window dictates the wait time between each copy.

Click the Required Protection Windowcheckbox.



21/50


When Enable RecoverPoint Snapshot Consolidationis selected, specific parameters can be set

to dictate when snapshot copies are consolidated.

Click the Enable RecoverPoint Snapshot Consideration checkbox.



22/50


Once all the parameters have been set, click OKto save the template.

Click OK.



23/50


A copy policy template can also be created via the CLI using the create_copy_policy_template

command.

In this example, we are creating a copy template named Copy1 with a protection window of

two weeks. This template has an unlimited journal size, but it can not get larger than 10 TB.The journal size will not be compressed. Up to twenty-five percent of the available copy journal

capacity can be used by the target journal. The template allows snapshots larger than the

capacity of the journal to be distributed among the journals.



24/50


The template maintains the default setting to allow replication with self-mirroring, which works

in conjunction with the Symmetrix splitter. A mix of operating systems can perform writes to

the logs. Snapshots older than three days will be consolidated up to four times daily and five

times weekly for all remaining snapshots.It is very important to get a message confirming that the copy policy template was completed

successfully.



25/50


To learn the process of creating a Link template, you will be instructed to click tabs, buttons

and drop-down menu items. The instructions for the remaining steps will appear to the right of

the screen.

If you wish to skip the steps, click the Nextbutton to advance to the Link Policy Template: CLIpage.

Policy templates allow the administrator to set specific parameters and apply them to a

consistency group efficiently. Create new policies from the Protectiontab.

Click theProtection tab.



26/50


Choose the Policy Templates option.



27/50


Click Add.



28/50


Select the Typedrop-down menu button.



29/50


From the Typedrop-down menu, select Link. This will display all options for a link policy

template for your specifications.



30/50


Protection Settings contain two replication modes: Asynchronous and Synchronous. For the

purpose of this module, we will talk about Synchronous mode settings and change settings for

Aynchronous mode.

The dynamic settings for Synchronous can be set to sync or near-sync via enabling Dynamic byThroughput or Dynamic by Latency.



31/50


For Asynchronous Replication Mode, Snap Replicationis the only available editable parameter.

Click the Snap Replication drop-down menu button.



32/50


Snap Replicationcan either be set to Off, On Highload or Periodic.

Select Periodicfrom the drop-down menu and keep the interval to five minutes, which is the

default.



33/50


Within the Link template, Compressioncan be configured to reduce bandwidth-related

activities on the cluster.

Click the Compressiondrop-down menu button.



34/50


Compression performance can be set on low, medium or high.

Select Mediumfrom the drop-down list.



35/50


Deduplicationcan be enabled by selecting the checkbox, as shown here.

Click OKto confirm the creation of the link policy template and continue.



36/50


As you can see, both the Link policy template (Link2) and copy policy template (Team1) have

been created and added to the list. They are ready to be imported into a CG during or after its

creation.



37/50


A link policy template is created by executing the create_link_policy_template command.

In this example, the template is named Link2. The replication mode is set to asynchronous and

the snap-based replication policy is continuous. When this link policy is applied, the first

initialization will quickly be performed. To reduce bandwidth, compression is set to low anddeduplication is also enabled. This specific template has no desired bandwidth.

It is very important to get a message confirming that the link policy template was completed

successfully.



38/50


To learn the process of creating Enhanced Group Sets, you will be instructed to click tabs,

buttons and drop-down menu items. The instructions for the remaining steps will appear to the

right of the screen.

If you wish to skip the steps, click the Nextbutton to advance to the Creating Enhanced GroupSets: CLI page.

Enhanced Group Sets can be configured via the GUI or the CLI. The Group Sets page can be

accessed by the Protectiontab.

Click the Protectiontab.



39/50


Select Group Setsto open the Groups Sets page.



40/50


The Groups Sets page displays the current list of Group Sets and allows you to create new

groups sets.

Click Addto create a group set.



41/50


There are four areas in the Add Group Set window that must be addressed in order to

properly create a group set.

First, the group set must have a name, which we named Team1.

Second, at least one CG must be selected and more can be added later, as long as all the CGsare replicating from the same site.

Third, enabling parallel bookmarking means that the group set is consistent, and a frequency

needs to be selected. The default frequency is set to 20 seconds. For a non-consistent group

set, uncheck Enable Parallel Bookmarking.

Click Okto confirm the creation of the group set.



42/50


In the Group Set management page, each group set is listed. In this case, the group set named

Team1 is shown. To manage that group set, select it and the available options will become

enabled at the bottom.

For the sampled group set, the available options are: Disable, Pause Transfer, Apply Bookmark,Test Copies, Fail Over and Recover Production.

Click Nextto continue.



43/50


Using the CLI, enhanced group sets are configured using the create_group_set command. In

this example, the group set is named Team1 that includes 001_Education and 003_Finance

consistency groups. It will be a consistent group set. Parallel bookmarking is performed every

15 minutes.A message displays to confirm that the group set was created successfully. Otherwise, a

message provides information to help troubleshooting the reason behind the error.

The get_group_set command is able to provide information about all configured group sets on

that cluster. For this cluster, there is only one group set configured with two consistency

groups.



44/50


This module focuses on the method to register an RPA cluster with the Install Base (IB) group

and to collect logs from a detached RPA cluster.



45/50


With RecoverPoint 4.1, the appliance automatically compiles and sends the necessary product

registration information to the EMC Install Base (IB), eliminating the manual registration

process required in earlier versions. The product registration information, which includes serial

numbers, connect home method, license type, software version and party ID, can be retrievedfrom the Adminsection by selecting Register RecoverPoint.

At the bottom of the page, there are two options Update Formand Send Form. The Send Form

option will allow you to send this information, as is, to the IB team by choosing one of two

methods: SYR or manually (email). By choosing the manual method, the form will be exported

into a CSV file and the CSV can be sent to the IB team via email.



46/50


The other option is Update Formwhere information about the cluster is manually entered into

the form for submission. This option can be used to correct any information that the system

may have collected incorrectly or to provide additional information about the cluster. Once the

form is completed by clicking OK, the registration can then be submitted using the Send Form.



47/50


Prior to this version of RecoverPoint, FTP availability check was performed after the cluster

collects its log. As a result, the log collection failed if the RP cluster/system could not reach the

FTP server. With RecoverPoint 4.1, the FTP availability check performs before log collection.

As in previous versions of RecoverPoint, the log can be retrieved by entering https:///info into a supported browser. Starting with this release,

admin/admin is used as username/password to access the info page, since webdownload has

been removed. For a production area, there will be more logs listed. Lets take a closer look at

this log.

This is the content of the tar file using 7-Zip. In this example, the processes are displayed

including Connectivity.sh and san_diag.sh. Double-clicking the Connectivity.sh file will open it.

The file shows the link status of both RPAs. This confirms that RPA2 is down and the log

collection still proceeded.



48/50


This course covered the method to enable snap-based replication, to register a VNX on an RPA

cluster, to create policy templates and configure enhanced group sets.

This concludes the training. Please, proceed to the course assessment.
