Abstract
CL_HACMP (Doc Number=4621): High Impact / Highly Pervasive APAR IV80637 IV80637 - rootvg loss is not detected
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.
With PowerHA 7.1 and 6.1, rootvg can be changed
to a Critical VG by running 'chvg -r Y rootvg'.
This will correctly cause the node to panic, despite this defect.
This feature is available on AIX 7.1 TL4 and AIX 7.2 and newer.
Affected AIX Levels and Recommended Fixes
Note: This problem affects PowerHA, but the defect is in AIX. Only the AIX levels shown below are affected.
Minimum Level Maximum Level APAR Fix Interim Fix 7100-04-00
bos.cluster.rte 7.1.4.0 7100-04-01
bos.cluster.rte 7.1.4.1 IV80637 iFix 7200-00-00
bos.cluster.rte 7.2.0.0 7200-00-01
bos.cluster.rte 7.2.0.1 IV80883 iFix Note: Installation of these fixes requires a reboot.
The table above describes which active levels are affected and where to obtain fixes.
Prior to the APAR Fix being available, an Interim Fix (iFix) is available for each affected level.
The available iFixes may only apply to the latest Service Packs. If a custom iFix is required please contact IBM Support.
The iFixes can be downloaded from the same location using ftp, http, or https.
