What are the following versions of:
 
1. HP
2. VM
3. Array
 
Does the syslog shows that vxdmp is disabling paths ?

Subject: [Veritas-vx] Disabled alternate paths on select luns in shared disk group

I'm having a problem with vxvm disabling only a few luns only on it's alternate path.  This is a shared disk group in a vcs environment.  The other node in the cluster can see both paths fine on all luns.   Since I can see some luns I'm thinking it's not a SAN configuration problem.  However, we've swapped out the fibre card.  Veritas support has been completely useless…they blame the SAN.  Our SAN support says it's fine and I believe them because I have 3 paths to the storage which are perfectly fine.   They've forced the luns down a new storage port and they all show up in an xpinfo after an ioscan and insf.   As soon as vxdctl enable runs and/or vxconfigd is stopped/restarted these 3 luns become disabled and no longer show up in xpinfo but do show up as claimed in ioscan.   Problem devices all show busy .  HELP!
