The OCP on either controller can be used to input the WWN and password data. For more
information about the OCP, see
“Operator control panel” (page 49)
.

Entering the WWN
Fibre Channel protocol requires that each controller pair have a unique WWN. This 16-character
alphanumeric name identifies the controller pair on the storage system. Two WWN labels attached
to the rack identify the storage system WWN and checksum. See
Figure 5 (page 23)
.
NOTE:
•
The WWN is unique to a controller pair and cannot be used for any other controller pair or
device anywhere on the network.
•
This is the only WWN applicable to any controller installed in a specific physical location,
even a replacement controller.
•
Once a WWN is assigned to a controller, you cannot change the WWN while the controller
is part of the same storage system.
