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 43) .
Table 1 (page 16) lists the push-button functions when entering the WWN, WWN checksum, and
password data.

Function Button
Selects a character by scrolling up through the character list one character at a time.
Moves forward one character. If you accept an incorrect character, you can move through all 16
characters, one character at a time, until you display the incorrect character. You can then change
the character.
Selects a character by scrolling down through the character list one character at a time.
Moves backward one character.
Returns to the default display. ESC
Accepts all the characters entered. ENTER
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 4 (page 16) .
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.

1. World Wide Name labels
Complete the following procedure to assign the WWN to each pair of controllers.
1.
Turn the power switches on both controllers off.
2. Apply power to the rack.
3. Turn the power switch on both controllers on.
NOTE: Notifications of the startup test steps that have been executed are displayed while
the controller is booting. It may take up to two minutes for the steps to display. The default
WWN entry display has a 0 in each of the 16 positions.
