Time and Items Required
If there is a need to replace one or both WWN cards, allow approximately 20 minutes. See Using the wwnrecover Utility
and WWN Card Fault Indicators before replacement.
The following items are needed to replace the WWN cards:
•
Electrostatic discharge (ESD) grounding strap
•
No. 1 Phillips screwdriver
•
Workstation computer
Using the wwnrecover Utility
The wwnrecover utility permits a recovery of WWN card data in the event of corruption. Recovery is not possible if
hardware issues prevent access to either WWN card or if the primary and backup copy of the license ID on either card is
corrupted.
Identical data must be maintained on each WWN card at all times so that if one card fails, the system can use the other
card to provide valid system operation. To maintain data and ensure its integrity, the system audits both WWN cards one
hour after the first system boot-up, every 24 hours after boot-up, and any time a WWN card is inserted to compare the
critical data.
