T 17. Return all remaining unchanged remote copy sets back to the original initiator. Use the following
command for each remote copy set:
SET RemoteCopySetName INITIATOR=InitiatorNodeName\InitiatorUnitName
Example: set rcs3 initiator=BUILDNGA\d3
I 18. From the initiator site, failback the controller to the original initiator site (refer to callout 9 on
Figure 12). Issue the following commands:
SET THIS_CONTROLLER PORT_Number_TOPOLOGY=OFFLINE
Example: set this_controller port_2_topology=offline
SET OTHER_CONTROLLER PORT_Number_TOPOLOGY=OFFLINE
Example: set other_controller port_2_topology=offline
SITE_FAILOVER RemoteNodeName\RemoteCopySetName
Example: site_failover BUILDNGB\rcs1
Several completion messages display that confirm the link is broken.
Refer to Example Display 38 for a sample completion message after performing the failover
command. The instance code confirms the action was completed.

I 19. Verify that all remote copy sets are now assigned to the initiator and are normalized. Issue the
following command:
SHOW REMOTE_COPY_SETS FULL
Refer to Example Display 39. Note that the target state is NORMAL.
