Prevent a duplicate PVID from being added to a VG

As can be read in PMR 14682,211,788 the system of our customer had created a PVID (which is a very low chance to happen). That disk was being added to the volume group which caused the failover-node to crash.

In some cases extendvg does not prevent a disk with
a duplicated PVID from being added to a VG. The extendvg
succeeds but later varyonvg will fail.

In the case of a concurrent VG in a cluster, the VG will
be forced offline on the remote node. In older AIX TLs
the VG will not get forced offline but the remote node
may crash during a subsequent change to the VG.


Chris Wickremasinghe (cwickrem@au1.ibm.com) from IBM Australia has created a draft APAR which was rejected by the Development team. The draft number is 12789.
