Reestablish the original protection relationship after an unplanned failover
ONTAP uses the ONTAP Mediator to detect when a failure occurs on the primary storage system and executes automatic unplanned failover to the secondary storage system. You can use ONTAP System Manager to reverse the relationship and reestablish the original protection relationship when original source cluster is back online.
Navigate to Protection > Relationships and wait for the relationship state to show “InSync.”
To resume operations on the original source cluster, click and select Failover.
