Enabling and Disabling Failover

If you want to break a cluster or need to take a V-Switch off-line, you must first
disable V-Switch failover. Use the CLI command cluster failover
disable

to disable this functionality. This command must be executed on

both V-Switches in the cluster.

If you want to restore a cluster or after you bring the V-Switch back on-line, you
need to re-enable the failover functionality. Use the CLI command cluster
failover enable

to re-enable this functionality. This command must be

executed on both V-Switches in the cluster.
