Reestablish the SnapMirror active sync relationship after an unplanned failover of your ASA r2 clusters

An automatic unplanned failover (AUFO) operation occurs when the primary cluster is down or isolated. The mediator detects when a failover occurs and executes an automatic unplanned failover to the secondary cluster. The secondary cluster is converted to the primary and begins serving clients.

Before you begin

  • The SnapMirror active sync relationship must be in sync.

  • You cannot initiate a planned failover when a nondisruptive operation, such as a storage unit move, is in process.

  • The ONTAP Mediator must be configured, connected, and in quorum.

  • To recover lost I/O paths or update I/O path states on your hosts, you need to perform a storage/adapter rescan on the hosts after the primary storage cluster resumes operation.

Steps

  1. Select Protection > Replication.

  2. Select the SnapMirror active sync relationship you need to reestablish.

  3. Wait for the relationship status to display InSync.

  4. Select three vertical blue dots; then select Failover to resume operations on the original primary cluster.
