HP ProLiant Cluster HA/F500 for MA8000 Enhanced DT Supplement Guide

Cluster Installation
10. Verify that the storage subsystem WWN, also called the NODE_ID, is set. The
WWN is not set if zeros are displayed. Go to step 14 if the WWN is set. If
the WWN has not been assigned to the controller, obtain the WWN and continue
with step 11.
CAUTION: Data corruption occurs if two subsystems are set to the same WWN.
NOTE: The storage subsystem WWN and checksum can be found on a sticker located
on top of the frame that houses the controllers, EMU, PVA, and cache modules. This
sticker also includes a checksum that verifies that the WWN is valid. Contact a customer
service representative for assistance if the sticker is missing. Refer to the StorageWorks
HSG80 Array Controller ACS configuration guide for more information on WWNs. Each
subsystem WWN begins with 5000 and ends in zero, for example 5000-1FE1-FF0C-
EE00. The controller port IDs are derived from the WWN.
11. Assign the WWN to the controller by entering the following command:
SET THIS NODE_ID=node_ID checksum
The display will be similar to Figure 2-3.
