You can upgrade an existing setup with the Failover Monitor to the High Availability CommServe Host.
Step1: Disable Automatic Synchronization Between the CommServe Hosts
Disable automatic synchronization as follows:
-
Start the Failover Monitor.
-
In the Failover Configuration tab, set Enable Synchronization of Nodes to No.
-
Click Update Configuration
Step 2: Terminate Synchronization Jobs in the Job Controller (Optional)
Terminate or kill synchronization jobs that are in progress using the Job Controller in CommCell Console. For more information on terminating jobs, see Killing a Job in the Job Controller.
Step 3: Stop cvfailovercommserv.exe in the Task Manager
Open the Windows Task Manager and stop cvfailovercommserv.exe if it is running.
Step 4: Rename the Configuration File
Rename cvfailover.cfg located in the <installation_directory>/cvfailover folder available in the second instance.
Step 5: Upgrade Instance 1 (CommServe Client) to the Current 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 6: Uninstall Instance 2 (SQL Client)
Uninstall Instance 2 (or the instance with SQL Server Agent and CommServe Failover packages) in the production CommServe host. For more information on uninstalling packages, see Uninstallations.
Step 7: Reinstalling Instance 2 (SQL Client)
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 8: Uninstalling Instance 1 and Instance 2 on the Standby CommServe Host
Uninstall the packages installed in Instance 2 (or the instance with SQL Server Agent and CommServe Failover packages) first, and then uninstall the packages in Instance 1. For more information on uninstalling packages, see Uninstallations.
Step 9: Reinstall Instance 1 and instance 2 on 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.
Step 10: 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 11: 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 12: Setup Failovers Using A Floating CommServe Name (Optional)
CommServe failover can be setup to use a virtual host name or a floating CommServe name. For more information, see Setting Up Failovers Using A Floating CommServe Name
Step 13: 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.
