Detecting Secondary Cluster Failure

When a secondary cluster for a protection group fails, a cluster in the same partnership detects the failure. The cluster that failed might be a member of more than one partnership, resulting in multiple failure detections.

During failure detection, the following actions take place:

  • Heartbeat failure is detected by a partner cluster.

  • The heartbeat is activated in emergency mode to verify that the secondary cluster is dead.

  • When a failure is confirmed by the Geographic Edition software, the cluster notifies the administrator. The system detects all protection groups for which the cluster that failed was acting as secondary. The state of the appropriate protection groups is marked Unknown.
