Detecting Cluster Failure on a System That Uses SRDF Data Replication

This section describes the internal processes that occur when failure is detected on a primary or a secondary cluster.

Detecting Primary Cluster Failure

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

The following actions take place when a primary cluster failure occurs. During a failure, the appropriate protection groups are in the Unknown state on the cluster that failed.

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:
