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.
