    "clq:  (C192716) I/O error." message when trying to add a quorum device

      A little bit of history: Recently our storage folks migrated us from CLARiiON LUNs to VNX LUNs on all the shared disks. At the time, the cluster booted fine. However, since all the DID device IDs changed, we no longer have a valid quorum device:

      <pre>bash-3.00$ sudo clq list
      bash-3.00$ sudo cldev show d11
      cldev: (C727402) Could not locate instance "11".

      When I try to add another quorum device I get the error shown in the title:

      <pre>bash-3.00$ sudo clq add d41
      clq: (C192716) I/O error.
      bash-3.00$ sudo cldev show d41

      Another issue we are having is that all the shared disks are showing "failed" for their status:

      <pre>bash-3.00$ sudo cldev status d41

      === Cluster DID Devices ===

      Device Instance Node Status
      --------------- ---- ------
      /dev/did/rdsk/d41 host1 Fail
      host2 Fail


      The old CLARiiON devices had array failover mode of 1 and the new devices have array failover mode of 4. Anyone know if that is an issue? I have MPxIO disabled in the fp.conf file.

      Any assistance would be greatly appreciated.
