Change WWNN? option

The Change WWNN? option displays the last five hexadecimal digits of the WWNN that is being used by the node. Only the last five digits of a WWNN vary on a node. The first 11 digits are always 50050768010.

To edit the WWNN, complete the following steps:
Important: Only change the WWNN when you are instructed to do so by a service procedure. Nodes must always have a unique WWNN. If you change the WWNN, you might have to reconfigure hosts and the SAN zoning.
  1. Press and release the up or down button until Actions is displayed.
  2. Press and release the select button.
  3. Press and release the up or down button until Change WWNN? is displayed on line 1. Line 2 of the display shows the last five numbers of the WWNN that is currently set. The first number is highlighted.
  4. Edit the highlighted number to match the number that is required. Use the up and down buttons to increase or decrease the numbers. The numbers wrap F to 0 or 0 to F. Use the left and right buttons to move between the numbers.
  5. When the highlighted value matches the required number, press and release the select button to activate the change. The Node WWNN: panel displays and the second line shows the last five characters of the changed WWNN.
