Devesh,

I have attached the output as requested.

Could it be a patching issue? looking at a similar thread, we are missing some patches...

[scroll to the bottom], patch PHKL_30607 is already installed on the system.

Tom,

have tried running a vgchange, results are as follows;

root@bddev:/> vgchange -a y /dev/vg01
vgchange: Volume group "/dev/vg01" does not exist in the "/etc/lvmtab" file.
root@bddev:/> vgchange -a y /dev/vg02
vgchange: Couldn't activate volume group "/dev/vg02":
Quorum not present, or some physical volume(s) are missing.

It seems your lvmtab is bad... Try this:

# mv /etc/lvmtab /etc/lvmtab.old
# vgscan -a

Hi Gurcharn,

As per output..

1.In the system vg01 and vg02 while activating its queery the PV belongs to VG.

2.Not able to find those so you have recevied above message.

possible way to find miised PV

1. Take the ouput of /etc/lvmtab

I have seen the your attachement in that vg01 entry not there and vg02 having one PV

It may possible that LVM header information get corrupted.

There could be other problem like PV's powerfailed, storage detached .

do following steps.

1.ioscan -fnC disk
2.mv /etc/lvmtab /etc/lvmtab.old
3.vgscan -v
4.activate all vgs
5.vgcfgbackup vgxx (taking all vg info backups)

Cheers,
Shankar

Hi,

Did "vgscan -a" worked?

I am having exact same problem, My machine model is same as yours.

Were you able to solve the problem.

Since I didn't have any data, I just wiped everything and did a rebuilt of Volume group, Logical Volume and File system. Every thing seems to be working fine !!!
