IT31356: FAILURE TO REMOVE VOLUME FROM HYPER-V CLUSTER AFTER SUCCESSFUL RESTORE

APAR status

• Closed as program error.

Error description

• After completing the restore of a Hyper-V guest in a Hyper-V
  cluster, following error message will be seen while unmounting
  the vSnap volume that is required for the restore:
  
  DETAIL,...,CTGGA1467,Removing volume (sppb_xxxx_vsnap) from
  Hyper-V host (HOST_1)
  DETAIL,...,CTGGA1467,Removing volume (sppb_xxxx_vsnap) from
  Hyper-V host (HOST-2)
  WARN,...,,Could not remove volume sppb_xxxx_vsnap from cluster
  CLUSTER
  DETAIL,...,CTGGA1467,Removing volume (sppb_xxxx_vsnap) from
  Hyper-V host (HOST-3)
  WARN,...,,Could not remove volume sppb_xxxx_vsnap from cluster
  CLUSTER
  
  Removing the volume will only succeed for the first Hyper-V host
  and fail for all other hosts in the Hyper-V cluster.
  This is because the volume is already removed successfully from
  the cluster after it is removed from the first host.
  
  This does not impact the Hyper-V guest restore itself, the
  restore will be complete successful.

Problem conclusion

• In certain cases the Hyper-V restore job will try to remove a
  cluster volume which has already been removed. Additional
  checking was added to prevent this. In older releases where it
  occurs the message can be ignored.
