To restore the WWNN, perform the following steps:
a. Determine the WWNN for the node by examining the vital product data (VPD) of the node or the
zoning that is defined in the SAN switch. Record the last five numbers of the WWNN for the
node that you are working on.
b. Start the node by performing a node rescue.
c. Change the node WWNN by performing the following steps:
1) On the front-panel display, press and release the down button until the Node panel is
displayed. Then press and release the right button until the Node WWNN: panel is displayed.
2) Press and hold the down button, press and release the select button, and then release the down
button. The display switches into edit mode. Edit 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.
3) Change the highlighted number to match the number from the VPD or from customer zoning.
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.
4) When the displayed value matches the numbers in the VPD or customer zoning, press and
release the select button to accept the numbers. The Node WWNN: panel is displayed and the
second line shows the last five numbers of the restored WWNN.
Wait one minute. If Cluster: is displayed on the front panel, this indicates that the node is ready to be
added to the system. If Cluster: does not display, see "MAP 5000" in the IBM System Storage SAN Volume
Controller Troubleshooting Guide to determine how to solve this problem or contact the IBM support center.
