Managing Site Failover and Failback Procedures 5–21
IMPORTANT: You must wait for normalization on all remote copy sets to complete before you
can proceed.
4. Shut down the target host.
5. Disable access to the target hosts by using the following CLI command:
SET UnitName DISABLE=(TargetHostConnectionNamex,TargetHostConnectionNamey)
6. Delete association sets by using the following CLI command:
DELETE AssociationSetName
7. If you added new remote copy sets since failover, proceed now to the section titled
“Adding Targets to New Remote Copy Sets.” Complete this three-part section before
returning to step 8 (below).
8. Reassign the remote copy sets to the initiator using the following CLI command:
SET RemoteCopySetName INITIATOR=InitiatorRemoteCopyName\UnitName
9. Enable the unit name by using the following CLI command:
SET UnitName ENABLE=(initremotecopysetA...)
10. Set maximum cached transfer size back to 1 with the following CLI command:
SET UnitName MAXIMUM_CACHED_TRANSFER_SIZE = 1
Repeat this step for each unit.
Initiator Clean-Up
1. To restore the connections to the initiator site, enable host access using the following
CLI commands:
SET THIS_CONTROLLER Port_1_Topology=Fabric
SET OTHER_CONTROLLER Port_1_Topology=Fabric
2. The target should be added at this time using the following CLI command:
SET RemoteCopySetName ADD=targetRemoteCopyName\UnitName
NOTE: The following is an example of this command’s use:
SET rcs1 add=buildngB\d1
Repeat this step for all remote copy sets.
