OTHER WWN 
UNKNOWN

The host Fibre Channel World Wide 
Names (node and port) previously 
presented by the other SM module 
(which is currently offline) in this 
system are unknown. This event has 
two possible causes:

The online SM module reporting the 
event was replaced or moved while 
the system was powered off. 

The online SM module had its flash 
configuration cleared (this is where the 
previously used WWNs are stored).

The online Storage Manager module 
recovers from this situation by 
fabricating a WWN for the other SM 
module based on its own serial 
number. If you see this event, then you 
need to verify the WWN information for 
the other SM module on all hosts that 
access it.

This SM module recovers from this 
situation by using WWNs based on its

WWN information for this SM module 
on all hosts that access it.
