5)Click OK to save the settings. The system will automatically elect a controller as the active one. Then the other one is standby.

The active controller displays Active in the Failover Status column, while the standby controller displays Standby. When the active controller becomes unavailable, the standby controller is switched as the active shortly for failover.

Note: If you remove an allocated tenant from a Front Server Controller, the Front Server registered to the Front Server Controller and the tenant will be removed correspondingly. To make the Front Server serve another tenant, you need to register the Front Server again.
