I 9. Delete the remote copy set. Refer to callout 4 on Figure 13. Use the command:
DELETE RemoteCopySetName
Example: delete rcs1
Example Display 50 shows a sample completion message. The instance code confirms the action
was completed.
Example Display 50

Instance Code: 0E020064
I 10. Prevent host I/O from accessing the original initiator LUN by setting port 1 to offline (refer to
callout 5 on Figure 13). Use the following commands:
SET THIS_CONTROLLER PORT_Number_TOPOLOGY=OFFLINE
Example: set this_controller port_1_topology=offline
SET OTHER_CONTROLLER PORT_Number_TOPOLOGY=OFFLINE
Example: set other_controller port_1_topology=offline
Several completion messages display that confirm the link is broken.
I 11. Prepare another LUN on the initiator subsystem (refer to callout 6 on Figure 13). Use commands
similar to the following:
INITIALIZE ContainerName
Example: initialize disk60300
ADD UNIT UnitNumber ContainerName DISABLE_ACCESS_PATH=ALL
Example: add unit d10 disk60300 disable_access_path=all
SET UnitNumber ENABLE_ACCESS_PATH=HostIDs
Example: set d10 enable_access_path=BUILDNGBa,BUILDNGBb,BUILDNGBc,BUILDNGBd
SET UnitNumber PREFERRED_PATH=THIS_CONTROLLER
Example: set d10 preferred_path=this_controller
SET UnitNumber MAXIMUM_CACHED_TRANSFER_SIZE=Number
BUILDNGA Top-> set d10 maximum_cached_transfer_size=128
T 12. From the target site, create a remote copy set to the initiator LUN to enable data to be copied (refer
to callout 7 on Figure 13). Use the following command:
ADD REMOTE_COPY_SETS RemoteCopySetName InitiatorUnitName RemoteNodeName\TargetUnitName
Example: add remote_copy_sets rcs1 d1 BUILDNGA\d10
Example Display 51 shows a sample completion message. The instance code confirms the action
was completed.
