IV86812: CLVER TREATS VG MAJOR NBR MISMATCH AS ERROR ALSO WITH NO NFS EXP

PowerHA-7.1.3 SP6

APAR status

• Closed as program error.

Error description

• The PowerHA cluster verification fails with an ERROR
  in case the major number of a shared VG is not the
  same on all nodes even if no NFS export is configured.

  root@ha2clJ:/ # ls -l /dev/clJvg1
  crw-rw---- 1 root system 45, 0 Sep 3 2015 /dev/clJvg1
  
  -> Major number for VG clJvg1 is not the same on
     both nodes.

  ...
  ERROR: The major number for VG clJvg1 is not the
   same on all nodes.
  ...
  Verification exiting with error count: 1
  
  The VG major number is only relevant if a filesystem or
  directory is exported via NFS. So in case no NFS export
  is defined a WARNING is sufficient.
  

Local fix

Problem summary

• The PowerHA cluster verification fails with an ERROR
  in case the major number of a shared VG is not the
  same on all nodes even if no NFS export is configured
  

Problem conclusion

• Modified code to display warning instead of error message
  where major number of shared VG is not same across all the
  nodes when NFS export is not configured.
  

Temporary fix
