Hello All ,
This is my first post here :
I am getting this error from the HP-UX 11i v3 (11.31) Host connected to Brocade DCX Backbone
vmunix usdadspsbduh0 lun path (class = lunpath, instance = 123) belonging to LUN (default minor = 0x1a) has gone offline.
What could be the issue ? could this be a zoning issue ? Please advice !

Appreciate if someone can take a look.

Usual suspects -- portCfgFillWord, cabling, SFP.
For a better answer I'd need to have a look at portShow <hostport#>, to start with.
Zoning is unlikely because (1) you've seen the LUN and (2) this looks like a link-level problem.

Thank you for looking into it -
Port status looks good to me , though .Is it with the Host itself , HPUX hosts 're know to log out from time to time .
Also, there isn't any SAN storage going to -5001438002ae1fd4

next up, you're running rather old driver version. Consider upgrading to the current release, B.11.31.1103 (but mind possible kernel patch dependencies too).
