Hi all,
On 19th March 2008 one of my hp ux server has automatically rebooted at 5:00 am.....

after that when i am going for vgdisplay on vg00, it giving me error:::

# vgdisplay -v vg00
vgdisplay: Couldn't query volume group "vg00".
Possible error in the Volume Group minor number; Please check and make sure the group minor number is unique.
vgdisplay: Cannot display volume group "vg00".

and

you can check that lvol1 has been recreated during that time..... as follows.....

# ll /dev/vg00
total 0
crw-r----- 1 root sys 64 0x000000 May 7 2002 group
brw-r----- 1 root sys 64 0x000001 Mar 19 05:02 lvol1

hi Ketul,
check /etc/lvmtab
/etc/fstab
check for EMS errors/events.
I hope running vgscan on vg00.

SHR

running vgscan will regenerate your lvmtab file. Its dangerous for your existing vg configurations.

It seems that you have assigned the same minor number to another vg.

check with ll /dev/*/group
