Hi, I had hdisk1 mirroring hdisk

[MoshiachNow]

Hi,

I had hdisk1 mirroring hdisk0 in rootvg VG.
AFter exercising with mirroring stuff I'm left with hdisk1 without a volume groupe,but the system still remembers that rootvg VG was mirrored.
I can not make the system forget it - unmirror or reducevg does not work,thay fail due to some residues of hdisk1 written somwhere on hdisk0 (system disk).
What can be done without reloading the system from scratch ?

unmirrorvg rootvg hdisk1

a volume group.
0516-1135 unmirrorvg: The unmirror of the volume group failed.
The volume group is still partially or fully mirrored. "Long live king Moshiach !"

wab62 had a problem similar to this back in May. Have a look in the index for:
How to fix mirrored lvs when a drive is replaced?

It sounds as though the ODM has got confused , and the VGDA does not match the ODM ,

one thing you can do is try re-defining the physical volume
so you are telling the volume group that the disk hdisk1 belongs to the volume group rootvg

redefinevg -d hdisk1 rootvg
( try it with -d first then use the pvid it it fails )
( if successfull , then try unmirror , remove disk and re-mirror)


Also have a look at this page 10 putlvodm , i.e. puts an entry in the ODM for the rootvg for the disk hdisk1 , that it thinks is missing . If successful then unmirror it , replace disk etc.)

Also haev you tried to reduce the copy manually
rmlvcopy LVname 1 hdisk?
then remove disk from vol group reducevg

synclvodm rootvg

 

[AIXSPadmin]

After your redefinevg, then do a synclvodm -Pv rootvg. Also, do a `chpv -c hdisk1` to clear any boot record that may exist on hdisk1.

Thanks to all.

By the time I was looking for solution some other clever guy have reloaded the machine from scratch .... "Long live king Moshiach !"

Does it works ?
If not what does bring you the lsvg -p rootvg ?
If there is a PVID, with no hdisk assignet in the Output, do the following steps.
for each lv do:
rmlvcopy lvname 2 "PVID in lsvg -p rootvg"
Controll with lsvg -l rootvg PV=1 !
syncvg -v rootvg
synclvodm -v rootvg
extendvg rootvg hdisk1
mirrorvg rootvg hdisk1
lsvg -l rootvg PV=2
