Disaster declaration

When a cluster in a global cluster transitions to the FAULTED state because it can no longer be contacted, failover executions depend on whether the cause was due to a split-brain, temporary outage, or a permanent disaster at the remote cluster.

If you choose to take action on the failure of a cluster in a global cluster, VCS prompts you to declare the type of failure.

You can select the groups to be failed over to the local cluster, in which case VCS brings the selected groups online on a node based on the group's FailOverPolicy attribute. It also marks the groups as being offline in the other cluster. If you do not select any service groups to fail over, VCS takes no action except implicitly marking the service groups as offline on the downed cluster.
