You can set up a High Availability CommServe Host for an existing CommServe server.
Step 1: Plan for High Availability CommServe Host Setup
Verify that the prerequisites needed to setup the environment are available before setting up the High Availability CommServe Host feature. For more information on the components needed to setup High Availability CommServe Host setup, see Planning for High Availability CommServe Host Setup.
Step 2: Upgrade the Existing (Production) CommServe Host to the Most Recent Service Pack
Upgrade the existing CommServe to the most recent Commvault feature release. For more information on the latest service pack and how to install it, see Service Packs.
Step 3: Install the CommServe Failover Package on the Production CommServe Host
The SQL Server Agent and the CommServe Failover package must be installed as a second instance. For more information on installing the CommServe Failover package, see Installing the CommServe Failover Package on the Production CommServe Host.
Step 4: Install the Standby CommServe Host
Install the Commvault software packages on the standby CommServe host. For more information on installing the packages on the production CommServe host, see Installing the Standby CommServe Host.
If you have an existing standby CommServe host, make sure to uninstall the software first, For more information on uninstalling the CommServe software, see Uninstalling the CommServe Software.
Step 5: Verify the Default Setup
Verify the setup from the production CommServe host to ensure that the default components are installed and configured properly. For more information, see Verifying the Default Setup.
Step 6: Enable the LiveSync Operations
Enable the CommServe LiveSync feature which facilitates CommServe Recovery Using High Availability CommServe Host. For more information on enabling the LiveSync operation, see Enabling and Disabling CommServe LiveSync.
Step 7: Verify Disaster Readiness
Perform a test failover to ensure successful production failovers. Test failovers do not affect the current jobs and activities on the production CommServe host. For more information on performing a test failover, see Verifying Disaster Readiness.
What to Do Next
Perform a production failover to switch the CommServe server from the currently active CommServe host to a standby CommServe host. For more information on performing production failovers, see Performing Production Failovers.
