You have a Duplicated Device, but WWN and not WWPN
procede with this one first, and try to Identify this Double WWN and remove if necessary.
<timestamp>, , <sequence-number>,, WARNING, <system-name>, Duplicated
WWN was detected with PID <existing device PID> and <new device PID>.
Probable Cause Indicates that an existing device has the same WWN as a new device that has come online.
The switch will process the new PID and leave the existing PID intact. Subsequent switch
operations will clean up the obsolete PID. However, administrators could check and remove devices
with a duplicated WWN.

I have one Question
Due to Duplicate FCID issue the Server Daemon (NSD) will crash and what could be the other reasons for NSD crash.
This inputs will be really helpful for me in resolving the the issue.
