Bad disk description stuck in VGDA - URGENT ! 1

[MoshiachNow]

Hi,This one is a bit tricky.
AIX 4.3.3. Had a mirrored rootvg,consisted of hdisk0 and hdisk5.
hdisk0 failed and was removed without unmirroring.
New hdisk0 was added with a different PVID.
Now all attempts all attempts to remove stale partitions fail :

redefinevg -d hdisk5 rootvg

synclvodm -Pv rootvg
0516-510 synclvodm: Physical volume not found for physical volume
identifier 004328daa95fc1400000000000000000.
0516-548 synclvodm: Partially successful with updating volume
group rootvg.
synclvodm: Logical volume hd5 updated.
synclvodm: Logical volume hd6 updated.
synclvodm: Logical volume hd8 updated.
synclvodm: Logical volume hd4 updated.
synclvodm: Logical volume hd2 updated.
synclvodm: Logical volume hd9var updated.
synclvodm: Logical volume hd3 updated.
synclvodm: Logical volume hd1 updated.

reducevg -d rootvg hdisk0
0516-022 lquerypv: Illegal parameter or structure value.
0516-022 lquerypv: Illegal parameter or structure value.
0516-884 reducevg: Unable to remove physical volume hdisk0.

because of the bad old hdisk0 PVID (004328daa95fc140) stuck in VGDA on the good hdisk5 :

So, you have removed disks which kept a copy (one of copies of hd6. Is it right? Now, when the disk is gone and replaced with new one, there are still informations that hd6 (one copy) resides on old disk (old PVID).

Maybe you should try to remove a zombie copy of hd6 (and not only hd6) from the configuration?

rmlvcopy hd6 1 OLD_DISK_PVID

If it would success then:

reducevg -df rootvg OLD_DISK_PVID


If not, then I have no clue.

ogniemi,this was one great tip !

"reducevg -df rootvg OLD_DISK_PVID" worked like a miracle !
Thanks !
