Revoering Volume Group On HP-UX A.09.00 C 9000/807

[Fabio Ettore]

Hi Amit,

just a thought...
It sounds like instance numbers for those disk devices changed.
In order to obtain new device files about disks you can try

# insf -e

and then

# vgscan -v

I hope this helps you.

Best regards,
Ettore

Hi, Tried insf -e and then vgscan but it is still saying "The Volume Group /dev/vg01/group was not activated with any physical volume" Why is it that the machine is able to sense the disk but still unable to attach that volume group with that disk. Anyone please help... Thanks, Amit.

It sounds like by now vg01 doesn't recognize any physical volumes attached.
Try:

# vgchange -q n -a y /dev/vg01

If there are physical volumes attached (and of course recognized yet) vg will be activated with it. Then try vgdisplay.

What does vgchange display?

Best regards,
Ettore

Hi Amit,

In my thought disk has gone bad physically but controller on disk may be fine becoz of that it is able to show in ioscan but not able to read from there.

I really think you need to not have a /etc/lvmtab before you do the "vgscan". Please "mv" your /etc/lvmtab to another name and then try it again.
