Reversing replication

Use this procedure to reverse replication if the remote consistency group (RCG) is in failover or switchover mode.

About this task

When the RCG is in failover or switchover mode, you can reverse or restore the replication. Reversing replication changes the direction so that the original target becomes the source. All data at the original source is overwritten by the data at the target. This option may be selected from either source or target systems.

Prerequisites

This option is available when RCG is in failover mode, or when the target system is not available. It is recommended to take a snapshot of the original source before reversing the replication for backup purposes.

Steps

  1. From the PowerFlex GUI, in the left pane, click Protection > RCGs.
  2. In the right pane, select the relevant RCG check box, and click More > Reverse.
  3. In the Restore Replication RCG <RCG name> dialog box, click Apply.
  4. Verify that the operation completed successfully and click Dismiss.
