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.
cluster failover disable
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.
