T 12. Verify that the subsystem WWN (also called the NODE_ID) has been assigned to the
controller. If zeros are displayed, the name is not set.
■ If the name is set, go to step 15.
■ If the WWN has not been assigned to the controller, you must obtain the name and set
it before proceeding.
Note: The subsystem’s WWN and checksum are located on a sticker on top of the frame that
houses the controllers, EMU, PVA, and cache modules. The checksum is required to verify that the
WWN is valid. If there is no label on the frame, contact your HP customer service representative for
assistance. Refer to Chapter 7 for more information on WWNs. Each subsystem’s WWN begins
with 5000 and ends with a zero; for example, 5000-1FE1-FF0C-EE00. The controller port IDs are
derived from the WWN.
Caution: Never set two subsystems to the same WWN; data corruption will occur.
T 13. After the WWN has been located (in step 12), assign it to the controller:
SET THIS_CONTROLLER NODE_ID=node_ID checksum
You should see a display similar to that in Example Display 2.

Restart of this controller required
Note: Do not restart the controller until the procedure instructs you to do so.
T 14. Issue a SHOW THIS_CONTROLLER command to verify that the WWN has been set.
You should see a display similar to that in Example Display 3.
