failback
(volumes)¶ Failover volumes back to primary backend.
The main steps: 1. Switch the role of replication pairs. 2. Copy the second LUN data back to primary LUN. 3. Split replication pairs. 4. Switch the role of replication pairs. 5. Enable replications.
-
failover
(volumes)¶ Failover volumes back to secondary array.
Split the replication pairs and make the secondary LUNs R&W.
