Error description

• ***************************************************************
  * USERS AFFECTED:
  * Systems running the AIX 7200-00 Technology Level
  * with bos.cluster.rte at the 7.2.0.0 or 7.2.0.1 level.
  ***************************************************************
  * PROBLEM DESCRIPTION:
  * PowerHA fails to panic a node when there is a loss of
  rootvg.
  * When there is failed I/O to a vg, disk down and vg down
  * events are not generated.
  *
  * This only affects PowerHA running on AIX 7.1 TL4 and AIX
  7.2.
  *
  * With PowerHA 7.2, rootvg is marked as a Critical VG by
  * default, which will correctly cause the node to panic,
  * despite this defect.

  * Install APAR IV80883.
  * Prior to fix availability, an interim fix is available from
  * either
  * ftp://aix.software.ibm.com/aix/ifixes/iv80883/
  * https://aix.software.ibm.com/aix/ifixes/iv80883/
  * The ifix can be installed using Live Update (LU).
  * If LU is not used, installation of the ifix requires a
  * reboot.
