Was this disk replaced some time back?
I think it was replaced or smthing and its not attached to any VG.
You will have to add the disk in vg then pvdisplay would give an output.

1) "hpvmdisplay" is not a recognised command


This needs to be run on the HPVM host, not the guest!

[maxell_1]

Ok geeks,

Beginning to see some light now.

1) Yes it is a VM guest.

2) Output of "strings /etc/lvmtab"
# strings /etc/lvmtab
/dev/vg00
/dev/disk/disk2_p2

3) Output of "ioscan -fnNC disk"
# ioscan -fnNC disk
Class I H/W Path Driver S/W State H/W Type Description

/dev/disk/disk4_p2 /dev/rdisk/disk4_p2
/dev/disk/disk4_p3 /dev/rdisk/disk4_p3

4) You can see that the device filename is not the same between the output in 2 and 3.

I think once the device mappings are right, things would be fine. Any help to sync the device filename?

Thanks

Ok
so what does
#hpvmstatus -P vm_name -v
shows, does it shows one disk or 2.
If 2 try running insf on this VM

2>check from which disk your server booted.

BR,

[Kapil Jha]

And try to mmv lvmtab
and run vgscan

What about
pvdisplay /dev/disk/disk4_p2
BR,
Kapil

[maxell_1]

This is the output run from the VM host.
svr1g2 is the vm guest having this problem.

[Torsten. · Accepted solution]

Because of this disk2 vs. disk4 problem, I would start with LVM maintenance mode and vgexport/vgimport vg00.

[Kapil Jha]

And you have got only one disk only assigned to VM.

So this is the only disk you have....

BR,

[maxell_1]

thanks all.

Ive managed to resolve the issue by going to VM maintenance mode and perform the VG manipulations:

************************************
vgchange -a n vg00
vgexport -m /tmp/vg00.map /dev/vg00
mkdir /dev/vg00
mknod /dev/vg00/group c 64 0x010000
vgimport -m /tmp/vg00.map /dev/vg00 /dev/disk/disk4_p2
vgchange -a y vg00
lvlnboot -R
vgdisplay
reboot
************************************

Thanks to All for your help ;)
