Failback

When a node becomes inactive for any reason, the Cluster service fails over any groups hosted by the node. When the node becomes active again, the Cluster service can fail back the groups originally hosted by the node.

The Cluster service fails back a group using the same procedures it performs during failover; that is, the Cluster service takes all of the resources in the group offline, moves the group, and then brings all of the resources in the group online.

Administrators and developers can configure how and when failback occurs for a group by adjusting the group's AutoFailbackType, FailbackWindowStart, and FailbackWindowEnd properties. For information on using properties, see Setting Properties.
