Declaring the type of failure

If a disaster disables all processing power in your primary data center, heartbeats from the failover site to the primary data center fail. VCS sends an alert signalling cluster failure. If you choose to take action on this failure, VCS prompts you to declare the type of failure.

You can choose one of the following options to declare the 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 in the failed cluster.
