I called IBM support for this - after some back and forth info exchange they recommended AIX upgrade to TL8 SP2, so I did this.
After upgrade problem is gone - during full vg loss cluster umounts filesystems just fine.
This one is solved.

As i have learned starting with Oracle 11.2 ASM can only be used in conjunction with Clusterware, which is Oracles HA-software. As is the companies policy we do intend to use PowerHA as HA-solution instead... (1 Reply)

As i have updated a lot of HACMP-nodes lately the question arises how to do it with minimal downtime. Of course it is easily possible to have a downtime and do the version update during this.

I have troubles making clstat work. All the "usual suspects" have been covered but still no luck. The topology is a two-node active/passive with only one network-interface (it is a test-setup). The application running is SAP with DB/2 as database. We do not use SmartAssists or other gadgets.

mkqdisk
mkqdisk(8) Quorum Disk Management mkqdisk(8)
NAME
mkqdisk - Cluster Quorum Disk Utility
WARNING
Use of this command can cause the cluster to malfunction.
SYNOPSIS
mkqdisk [-?|-h] | [-L] | [-f label] [-c device -l label] [-d [-d ...]]
DESCRIPTION
The mkqdisk command is used to create a new quorum disk or display existing quorum disks accessible from a given cluster node.
OPTIONS
-c device -l label
Initialize a new cluster quorum disk. This will destroy all data on the given device. If a cluster is currently using that device
as a quorum disk, the entire cluster will malfunction. Do not run this on an active cluster when qdiskd is running. Only one
device on the SAN should ever have the given label; using multiple different devices is currently not supported (it is expected a
RAID array is used for quorum disk redundancy). The label can be any textual string up to 127 characters - and is therefore enough
space to hold a UUID created with uuidgen(1).
-f label
Find the cluster quorum disk with the given label and display information about it.
-L Display information on all accessible cluster quorum disks.
-d Increase debugging level. Specify multiple times for more information. Currently, specifying more than twice has no effect.
