IV65911: VARYOFFVG W/ PASSIVE NODES ONLINE IN CLUSTER LEAVES VARYON STATE APPLIES TO AIX 7100-03

APAR status

• Closed as program error.

Error description

• In AIX 6.1 TL8, 7.1 TL2, and above, varyonvg may fail
  with the following message, even though the volume group
  is varied off on all nodes:
  
  0516-1972 varyonvg: The volume group is varied on in
  other
  node in concurrent mode; you cannot vary on the volume
  group in non-concurrent mode.  Use -O flag to force
  varyon the volume group if needed.
  
  This can happen for concurrent VGs if the last varyoff is
  from a passive-mode VG.
  

Local fix

• Use varyonvg -O after checking that the volume group is
  not
  varied on at any node.

Problem conclusion

• Modify behavior of LVM so that when going offline, or going
  from active to passive mode, when LVM checks all nodes in the
  cluster to see if any node is left online, it will ignore
  nodes that are online in passive-only mode.
  
  So when the last active mode node in the cluster is varied
  off (or brought to passive-only mode), it will clear the
  varied on state from the disk.
