5. Contact IBM Support for replacement of WWN cards. IBM Support will request the partner or OEM
to send WWN cards from FRU inventory to the nearest IBM Support office to be reprogrammed. IBM
Support will require the
Supportsave data taken in the previous step so that the replacement cards
can be reprogrammed prior to shipping to the partner or your site. If support has determined that
both WWN cards need replaced, you must replace both WWN cards as a matched pair.
Hot-swap replacement
You may replace one WWN card assembly at a time with the system powered on using the following
steps to avoid interruption of system operation.
About this task
Use this procedure if Customer Support has determined that a WWN card needs replaced and you have
received replacement cards. These procedures require that you use the
wwnrecover utility. For more
information on this utility, refer to “Using the wwnrecover utility” on page 152.
You can use this procedure to replace one WWN card assembly at a time while power is on. Follow all
steps for one card, and then repeat the same steps to replace the other card assembly. To replace both
WWN card assemblies simultaneously, use procedures under “Cold-swap replacement” on page 156.
