Maintenance failovers can be used to temporarily halt all activities except restores in the CommCell. Use the following steps to perform maintenance related activities without completely shutting down the CommServe server. For example, to install Feature Releases on the production CommServe host.
Note: If necessary, you can also directly install the Feature Release on the production CommServe host (Step 2), if you can plan some downtime for the production CommServe host.
Step 1: Initiate a Maintenance Failover
Set the CommServe server on restore-only mode by performing a maintenance failover to the standby CommServe host. For more information on performing a maintenance failover, see Initiating Maintenance Failovers.
Step 2: Install the Feature Release On the Production CommServe Host
Install the feature release on the Production CommServe host. For more information on installing feature releases on the production CommServe hosts, see Installing a Feature Release on the Production CommServe During a Maintenance Failover.
Step 3: Reset Maintenance Failovers
Switch CommCell operations back to the production CommServe host by resetting the maintenance failover. For more information on resetting the maintenance failover, see Resetting Maintenance Failovers.
Step 4: Install the Feature Release On the Standby CommServe Host and SQL Clients
Install the feature release on the Standby CommServe Hosts and SQL Clients. For more information on installing the feature release, see Installing Feature Releases On the Standby CommServe Host and SQL Clients.
