TT 8. Create the LUNs at the new target site that will match the old target LUNs. Refer to callout 4 on
Figure 14. Use the commands:
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 preferrred_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=BUILDNGBa,BUILDNGBb,BUILDNGBc,BUILDNGBd
T 9. Create the connections between the old and new target sites. Refer to callout 5 on Figure 14. Use
the following command:
ADD REMOTE_COPY_SETS RCS199 D199 InitiatorControllerName\D199
Example: add remote_copy_sets rcs199 d199 buildngc\d199
NOTE: This command will fail with the error message “initiator unit specified not found.” However, it will create and
name the connections appropriately.
T 10. Verify that the old target has access to the new target controller with the following command:
SHOW CONNECTIONS
Example Display 60 shows a sample output of this command.
