T 5. Physically replace the target LUN and re-create this new disk with the following commands (refer
to callout 3 on Figure 9).
DELETE UnitNumber
Example: delete d1
INITIALIZE ContainerName
Example: initialize disk10000
ADD UNIT UnitNumber ContainerName DISABLE_ACCESS_PATH=ALL
Example: add unit d1 disk10000 disable_access_path=all
SET UnitNumber PREFERRED_PATH=THIS_CONTROLLER
Example: set d1 preferred_path=this_controller
SET UnitNumber MAXIMUM_CACHED_TRANSFER_SIZE=Number
Example: set d1 maximum_cached_transfer_size=128
SET UnitNumber ENABLE_ACCESS_PATH=HostIDs
Example: set d1 enable_access_path=BUILDNGAa,BUILDNGAb,BUILDNGAc,BUILDNGAd
T 6. Display the characteristics of the created LUN by issuing the following command:
SHOW UnitNumber
Example: show d1
Example Display 4 shows a sample output from the SHOW command.

command:
SET RemoteCopySetName ADD=RemoteNodeName\TargetUnitName
Example: set rcs1 add=BUILDNGB\d1
Refer to Example Display 5 for a sample completion message. The instance code in the
completion message confirms that the action was performed.
