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!
