    Path missing on one hba

    Jae Ellers Master

      Just updated an existing ESX 3.0.1 server to add 2x HP FCA2214, aka QLA2340 single channel, 2 Gb cards.

       

      I'm already running 3 other servers against 4 luns on an EVA 8000.

       

      After the san admin zoned the system in, everything was fine.  4 luns, 4 paths on the SAN, 2 HBA, so 8 paths per lun, 4 on each hba.

       

      Then the fun started.  After flipping back and forth among servers comparing configurations, I noticed there were no luns showing up on vmhba1.  I refreshed, then rescanned a few times.  The luns showed back up, but with only 3 paths to the san on vmhba1.  There are still 4 paths on vmhba2.

       

      Any ideas?  Here are the outputs of esxcfg-mpath -l for this system and another system to compare. 

       

      Broken (7 paths):

      Disk vmhba2:0:1 /dev/sda (409600MB) has 7 paths and policy of Fixed

      OK (8 paths) this system has single dual-port card

      Any ideas? 

       

      Also, on this system, doing a rescan from the command line yield different results on different nics:

      \[root@tekvm1 log]# esxcfg-rescan vmhba1

      Rescanning vmhba1...done.

      On scsi0, removing:.

      On scsi0, adding:.

      \[root@tekvm1 log]# esxcfg-rescan vmhba2

      Rescanning vmhba2...done.

      On scsi1, removing: 0:0 0:1 0:2 0:3 0:4.

      On scsi1, adding: 0:0 0:1 0:2 0:3 0:4.
