So I was playing around with my IA64 HP-UX servers trying to get it to connect to my Nexenta CE based fibre channel SAN and was having troubles.
fcmsutil shows:

I tried many things wasting many hours - tried in both FCAL and Fabric connections (hard and soft zoning) but this is as far as I have gotten. HP-UX will not detect the LUN and just shows target as "Target port is in invalid state". Since this is a hobby I always seem to google last. I mean, this is just supposed to work and if it doesn't, I didn't think I'd find much in the way of information on it anyway. I did end up finding this gem of a mailing list post though.

Haven't started yet. Will probably start in two weeks.

I don't have a problem with this but our current solution is simply a
hack, treating SCMD_WRITE_G1 like SCMD_WRITE_VERIFY (which basically
makes SCMD_WRITE_VERIFY just a WRITE with no VERIFY). I'll see if we
have time to produce a "correct" version that fully supports VERIFY.
And, if we do, we would like to push the code back upstream. When we
have something, I'll ping.

Great, thanks.

Annnnnnd then nothing of interesting value...
So I'm considering just shelving the whole HP-UX cluster until I either find a use for it or get a proper SP. I mean I am trying real hard to find a use for them but for now, in my basement, Itanium is dead.
---EDIT--- 2013-12-23 10:54PM
I configured the iSCSI initiator and added the iqn into the initiator group in Nexenta and now it seems the LUN is showing up in ioscan... I don't understand how only adding the IQN into the initiator group on the Nexenta fixed it - the WNN was in there and it didn't work... oh well!
