162
Warning The host WWNs (node and port) previously presented by this controller module are unknown. In a
dual-controller system this event has two possible causes:
• One or both controller modules have been replaced or moved while the system was powered off.
• One or both controller modules have had their flash configuration cleared (this is where the previously
used WWNs are stored).
The controller module recovers from this situation by generating a WWN based on its own serial number.
Recommended actions
• If the controller was replaced or someone reprogrammed its FRU ID data, verify the WWN information
for this controller module on all hosts that access it.
