CommServe Hardware Refresh: Configuring a Cluster Environment

If you moved the CommServe database from a cluster to another cluster, you need to perform the following steps in the new environment.

Before You Begin

  • Log on to both the active and passive nodes of the new cluster environment and ensure that the network details (computer name and IP settings) are properly set.

  • Go the active node of the new cluster environment and copy the Disaster Recovery backup files to the local drive.

    The disaster recovery backup files were saved during the Preparing the Old CommServe Computer for Shutdown procedure.

  • Install the CommServe software in your new cluster environment. During the installation, submit the database dump file that you saved to the local drive.

    For the installation instructions, see Installing Server Packages in a Cluster Environment.

Procedure

Step 1: Recovering the CommServe Database Using the Recovery Assistant Tool on New Microsoft Failover Cluster

  1. Login to the active node's physical machine in the new cluster

  2. Open Commvault Process Manager on active node and stop all Commvault services.

  3. Check the active node in Microsoft Failover Cluster Manager.

    Make sure Commvault cluster role status is partially running with only Commvault services stopped under Roles. Also, make sure current node is still active. If it failed over to another node, then fail back to this node.

  4. On the CommServe computer, go to the <software installation path>\Base folder and double-click CSRecoveryAssistant.exe.

  5. In the CommServe Recovery Assistant dialog box, click Recovery, and then click Next.

  6. Write the confirmation text, and then click Next.

  7. In the Enter the path to the database dump folder box, enter or browse the name of the disaster recovery folder where the dump files from Step 8 of Preparing the Old CommServe Computer for Shutdown as mentioned in the Before you Begin section, and then click Next.

    Make sure that the dump files are available on the local disk of this New CommServe host.

  8. In the Enter the path to extract the database files box, type the destination path where you want to restore the CommServe database files, and then click Next.

    Alternatively, click Browse, and then select the restore path.

    By default, all the database files are restored to the CommServe database path located on the destination CommServe host.

  9. In the Summary screen, review the selections, and then click Start Recovery.

    The tool now performs the following operations on the CommServe system:

    1. Stop services on your CommServe computer

    2. Restore the database to the specified restore path

    3. Verifies and upgrades the database if required

    4. The tool can upgrade the database from a previous version or service pack.

    5. Synchronize the CommServe system and the restored database

  10. When all the operations are complete, click Next.

    The host name and client name of the destination CommServe host and the restored database appear. If the names are different, the tool updates the CommServe host with the client name of the restored database and host name of the destination CommServe host.

  11. If the IP address of the destination CommServe host is different from the original production CommServe host, select the Provide a license file check box and enter the path to a new IP address change license file in the text box provided, and then click Next.

    Note: If you do not have a new license, contact your Commvault Account Manager or Support for a new license. It is optional to provide a license file if the tool detects no change in the CommServe IP address in the existing license file.

  12. In Cluster to Cluster conversion screen, select Specify cluster nodes checkbox and in the Physical Node text boxes type the names of the physical CommServe nodes as they appear in the Microsoft Failover Cluster Manager under Nodes, and click Next.

    Do not copy and paste the physical node name from the registry or add the characters "_node" to the node name. The characters "_node" are automatically added to the physical node name during the database restore operation.

    A completion message appears.

  13. Click Finish.

    The database will be converted from old cluster to new cluster environment.

  14. Open Microsoft Failover Cluster Manager. navigate to the cluster, and then select Roles.

    Make sure Commvault cluster role status is Partially running with only Commvault services stopped under Roles. Also, make sure that the current node is still active. If cluster failover happened to another node, then fail back to this node.

  15. Under right side panel, select Roles.

  16. Right-click on the SQL Server Commvault cluster role, and then select Start Role.

  17. Log on to the CommCell Console.

  18. Navigate to CommCell Browser > Client Computers.

    The old Microsoft Cluster Environment Physical nodes will be now visible with ‘_Node’ suffix in their name and ‘_Decommissioned’ suffix in their hostname.

    This decommissioned old cluster physical nodes can now be safely retired or deleted.

  19. Update DR Backup Metadata folder path to reflect a new location under new Cluster Drive in this New Microsoft Failover Cluster environment.

  20. To update this, navigate to CommCell Console > Home > Control Panel > DR Backup, and then update the value for Back Up Metadata to this folder.

  21. Perform Step 5 to Step 12 under Procedure of topic Alternative Method: Install the CommServe Software, and then Restore the Database under CommServe Hardware Refresh: Setting Up the CommServe Database in the New Hardware.

Step 2: Configure an Additional Setting to Send Update Status to the CommServe

  1. Log on to the CommCell Console.

  2. In the CommCell Browser, right click the <CommServe> computer, and then click Properties.

  3. Click the Additional Settings tab, and then click Add.

  4. In the Add Additional Settings on Windows Client dialog box, do the following:

    1. In the Name box, type bSendUpdateStatusToCS.

    2. In the Category box, type UpdateFlags.

    3. From the Type list, select INTEGER.

    4. In the Value box, type 1.

    5. Click OK.

  5. Click OK to close the CommCell Properties dialog box.

  6. Restart the CommCell services using the Process Manager. For instructions, see Restarting a Service.

Step 3: Perform CommServe Hardware Refresh: Post Migration Operations

  1. Please perform recommended operations on the new CommServe computer after the hardware refresh documented here: CommServe Hardware Refresh: Post Migration Operations.
