You can manually force a failover from a primary high-availability (HA) host to a secondary HA host.
Manually forcing a failover is useful for planned hardware maintenance on a console or managed host. Ensure the following before you conduct a manual failover:
- The primary and secondary HA hosts are synchronized.
- The secondary HA host has a status of standby.
To perform a manual failover on the primary HA host, set the primary system to offline to make the secondary HA host active. After the secondary host becomes active, you can perform maintenance on the primary host.
To perform a manual failover on the secondary HA host, set the secondary system to offline. After the primary host becomes active, you can perform maintenance on the secondary host.
Do not manually force a failover on a primary HA host when you install patches or install software upgrades. For more information, see the IBM QRadar Upgrade Guide.
