Installing the Standby CommServe Host

Updated

Install the Commvault software packages on the standby CommServe host. You can also setup more than one standby CommServe hosts, if necessary.

Before You Begin

  • Install the Production CommServe Host.

  • Verify that the prerequisites needed to setup the environment are available before setting up the CommServe LiveSync feature. For more information on the components needed to setup CommServe LiveSyncs, see Planning for the CommServe LiveSync Setup.

  • Download the Commvault software installation packages. For more information on how to download the software, see Download the Commvault Software.

  • Verify and ensure that Two-Factor Authentication is either disabled, or use an account without Two-Factor Authentication to install the standby CommServe host.

    Standby CommServe installation will fail if Two-Factor Authentication is enabled at the CommCell level with Time-based One-Time Password. Instance002 will install successfully, but instance001 will fail as it will try to use the same credentials which is only valid for 1 time. For more information, see the following topics:

Procedure

  1. Log on to the standby CommServe host as an Administrator or as a member of the Administrator group on that computer.

  2. Launch theCommvault software installation package.

    The Download Manager dialog box appears.

  3. Click Extract.

    The Language Selection page appears.

  4. Select the language from the Please Choose a Language list, and then click the arrow to proceed.

    The Welcome page appears.

  5. Select I Agree, and then click the arrow to proceed.

    The Choose the Installation Type page appears.

  6. Click Install packages on this computer, and then click the arrow to proceed.

    The Install Option page appears.

  7. Select one of the options and then continue with either Step a or Step bs follows:

    1. Select Advanced selection, and then click the arrow to proceed to Step 8, below.

    2. To install a failover host, do the following:

      1. Select Create a new Commcell, and then click the arrow to proceed.

        The Select Roles screen appears.

      2. Select All in one or Server components. For more information, see Installation Roles and Packages.

      3. Select CommServe failover node, and then click the arrow to proceed to Step 10, below.

  8. The Select Packages page appears.

  9. Select the following, and then click the arrow to proceed.

    • CommServe

    • CommServe Failover

      Note: The CommServe Failover package automatically installs the SQL Server agent and the CommServe Failover packages in a new instance. (No additional user intervention is needed.)

  10. The Failover Install Option page appears.

  11. Select This is a standby node, and then click the arrow to proceed.

    The Installation Path page appears.

  12. Verify the path (or specify a new path) for the SQL client, and then click the arrow to proceed.

    Note: This Installation Path is for the SQL client, as the SQL client is installed first on the standby CommServe host.

    The Installation Summary page appears.

  13. Verify the list of packages, and then click the arrow to proceed.

    The software installs the binaries for setting up the SQL client. This process may take a few minutes.

    The Client Computer Information page appears.

    The Client Name and Host Name prompts are for the SQL client in the standby CommServe host. (This is the standalone SQL agent installed in Instance002, which is used for restoring the SQL database which was backed up from the production CommServe host. Note that this is NOT the name used by clients to connect to this CommServe host when it is active; the CommServe Client name used by clients should be provided later in Step 22, below.)

    Tip: Choose a meaningful Client Name to clearly differentiate this client in the user interfaces like Command Center / CommCell Console. For example, you can add the word SQL to differentiate it from the CommServe client.

    The Server Information page appears.

  14. Enter the Fully Qualified Domain Name (FQDN) of the production CommServe host (note that this is the name that you noted while installing the production CommServe host).

  15. Select Server will connect back to this computer to complete install if the CommServe computer must initiate communications with the client. For more information about configuring direct connections from the CommServe computer, see Configuring Direct Connections from the CommServe Computer to the Client.

  16. Click the arrow to proceed.

    The Server Authentication page appears.

  17. Select an authentication method for accessing the production CommServe host, and then click the arrow to proceed.

    The software installs the binaries for setting up the SQL client. This process may take a few minutes.

    The Additional Configuration page appears.

  18. Optional: Select the Subclient Policy, Storage Policy and Client Group associated with the SQL client, and then click the arrow to proceed.

    If you do not want to configure these options, skip this step and proceed to the next page. These settings can be customized later after the installation.

    Note: This completes the SQL Client installation and the following prompts are displayed for installing the standby CommServe client.

    The Installation Path page appears.

  19. Verify the path (or specify a new the path) for the standby CommServe server, and then click the arrow to proceed.

    Important: Note that this Installation Path is for the CommServe server.

    The Index Cache Path page is displayed.

  20. Verify the index cache path (or specify a new path), and then click the arrow to proceed.

    Make sure to have the same path in the production and standby CommServe hosts.

    The CommServe Database Installation Path page appears.

  21. Verify the CommServe database installation path (or specify a new path) and then click the arrow to proceed. (This is the path for storing the CommServe server databases.)

    Make sure to have the same path in the production and standby CommServe hosts.

    The Disaster Recovery Path page appears.

  22. Select Use Network Path or Use Local Path, enter the path in Disaster Recovery Backup Files Path, and then click the arrow to proceed.

    The Client Computer Information page appears.

  23. Enter the CommServe client name in the Client Name field, and then enter the standby CommServe host name in the Host Name field. The Client Name is the CommServe client installed in Instance001. Note that this is the name used by clients to connect to this CommServe when it is active. The Host Name is the Fully Qualified Domain Name (FQDN) of the standby CommServe host.

    The software creates the databases and services. This process may take a few minutes.

    A message similar to the following appears:

  24. Click Finish to complete the installation.

Note:

  • To troubleshoot errors that occur before the installation summary page, check the %allusersprofile%\Commvault Systems\Galaxy\LogFiles\Install.log file.

  • If the error occurs after the summary page, check the installation logs in the software_installation_directory\Log Files folder.

What to Do Next

  • Enable the CommServe LiveSync feature which facilitates CommServe Recovery Using CommServe LiveSync. For more information on enabling the LiveSync operation, see Enabling CommServe LiveSync.

Additional Notes

Any additional packages installed on the primary CommServe host, which includes other Commvault packages, or any third-party components, must be manually installed in the standby CommServe host. Also once the LiveSync operation is enabled, the LiveSync process will synchronize the information stored in the CommServe database from the production to the standby CommServe. For example, passwords and Additional Settings stored in the database. Any additional entities, such as third-party packages, scripts, registry keys, certificates, IIS settings, configuration files, etc. must be manually applied before or after failover as needed.
