I 10. Verify that the subsystem WWN, also called the NODE_ID, is set (if zeros are displayed,
the name is not set):
■ If the name is set, go to step 13.
■ If the WWN has not been assigned to the controller, you must obtain the name 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. This sticker also includes a checksum, which is
required to verify that the WWN is valid. If no label is present, contact your HP customer service
representative for assistance. For more information on WWNs, refer to the

for your operating system.
Each subsystem’s WWN begins with 5000 and ends in 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.
I 11. After the WWN has been located, assign it to the controller:
SET THIS_CONTROLLER NODE_ID=node_ID checksum
You should see a display similar to that in Example Display 25.
