Setting up a controller pair using the OCP
NOTE:
This procedure should be performed by an HP authorized service representative.
Two pieces of data must be entered during initial setup using the controller OCP:
• World Wide Name (WWN)—Required to complete setup. This procedure should be performed
by an HP authorized service representative.
• Storage system password—Optional. A password provides security allowing only specific
instances of HP Command View EVA to access the storage system.
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 " on page 69.
Table 2 lists the push button functions when entering the WWN, WWN checksum, and password data.
Table 2 Push button functions
Button Function
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.
ESC Returns to the default display.
ENTER Accepts all the characters entered.
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 .
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.
