If you made the decision to remove remote copy set targets, go to Step 3.
If you made the decision to NOT remove remote copy set targets, go to Step 5.
5. Re-create association sets and then write history logging to duplicate those that are on
the initiator.
Repeat this step for each association set.
NOTE: Refer to the Configuration chapter for information on how to create association sets and
configure association sets for write history logging.
Target Host Setup
1. Give the target site hosts access to the units in its storage subsystems with this
command:
SET UnitName ENABLE=(TargetHostConnectionNamex,TargetHostConnectionNamey)
If you do not recall the target host connection name, use the SHOW CONNECTION
command.
Repeat this step for each unit.
2. You can enhance host I/O performance by resetting the maximum cached transfer size
to the value used on the initiator. Use this command:
SET UnitName MAXIMUM_CACHED_TRANSFER_SIZE = initiator value
NOTE: The default maximum cached transfer size is 32
Repeat this step for each unit.
3. To verify that all of these steps have been completed successfully, issue these CLI
commands:
SHOW REMOTE_COPY_SETS FULL
The output shows you a list of remote copy sets.
3. To remove the targets, use the following CLI command:
SET RemoteCopySetName REMOVE=InitiatorRemoteCopyName\UnitNumber
Example: SET rcs1 REMOVE=buildngA\d1
4. Repeat this step for all remote copy sets.
NOTE: The InitiatorRemoteCopyName is the remote copy name of the original initiator.
Proceed to the Target Host Setup section, step 1 (below).
