On a non-VSS switch with redundant supervisors (say Active Supervisor in slot 5, Standby supervisor in slot 6), the "redundancy force-switchover" command causes the Standby. It automatically recovers the maximum amount of redo data for the protection mode the configuration is operating in. If you issue the reload command and the status is not standby hot or standby cold, the reload command will reset the current supervisor engine and the peer supervisor may not be able to take over because it was not in a. The auto-failover groups feature allows you to manage the replication and failover of some or all databases on a logical server to a logical server another region. If the higher priority switch is currently in VSS Standby state, you can make it the VSS Active switch by initiating a switchover with the redundancy force-switchover command.
