Unable to match these physical volumes to a volume group

[Shukor]

My rp2405 unable to boot up due to this error on "Unable to match these physical volumes to a volume group". I boot into maintenance mode lvm and here is my latest ouput.
# vgdisplay -v vg00
vgdisplay: Volume group "/dev/vg00" does not exist in the "/etc/lvmtab" file.
vgdisplay: Cannot display volume group "vg00".

# ioscan -fnC disk

Need your help please. Thanks in adv.

Do these

1) cp /etc/lvmtab /etc/lvmtab.old
2) vgscan -a -v
3) strings /etc/lvmtab
4) vgchange -a y vg00
5) vgchange -a y -q n vg00

[Shukor]

I did

1) cp /etc/lvmtab /etc/lvmtab.old

2) vgscan -a -v
# vgscan -pv
vgscan: Warning: couldn't query physical volume "/dev/dsk/c1t15d0":

vgscan: Warning: couldn't query physical volume "/dev/dsk/c3t15d0":

Following Physical Volumes belong to one Volume Group. Unable to match these Physical Volumes to a Volume Group. Use the vgimport command to complete the process.
/dev/dsk/c1t15d0

3) strings /etc/lvmtab
sh: strings: not found

4) vgchange -a y vg00
vgchange: Warning: Couldn't attach to the volume group physical volume "/dev/dsk/c3t15d0":

Quorum not present, or some physical volume(s) are missing.

5) vgchange -a y -q n vg0
(not yet coz not serial connected to server)

You did only copy the lvmtab file, not move.

Both disk are already recorded in lvmtab, so there is likely no need to do a vgscan.

However one of the disks maybe bad.

Try

# dd if=/dev/rdsk/... of=/dev/null bs=4096

and see if this completes without error.

I would try to remove disk c3t15d0 and boot with quorum mode.
I assume your disks are mirrored.

Hi

move the lvmtab file to lvmtab.old not to copy.Then do vgscan as said earlier.

Hi,

In the maintenance mode, I did teh said steps but returned with errors.

# mv /etc/lvmtab.org /etc/lvmtab

# vgchange -a y -q n vg00
vgchange: Volume group "/dev/vg00" does not exist in the "/etc/lvmtab" file.

# vgscan -pv
vgscan: Couldn't access the list of physical volumes for volume group "/dev/vg00".
Couldn't stat physical volume "/dev/dsk/c3t15d0":
Invalid argument

vgscan: has no correspoding valid raw device file under /dev/rdsk.
Verification of unique LVM disk id on each disk in the volume group
/dev/vg00 failed.

# dd if=/dev/rdsk/c1t15d0 of=/dev/null bs=4096
sh: dd: not found

> mv /etc/lvmtab.org /etc/lvmtab

You need to rename lvmtab -- it must not exist. Use the command exactly:

mv /etc/lvmtab /etc/lvmtab.org

Now lvmtab is gone. Now you can rebuild the file correctly:

vgscan -a

> vgchange -a y -q n vg00

vg00 does not exist -- if the vgscan works OK, then vgchange will work.

> vgscan: has no correspoding valid raw device file under /dev/rdsk.
> Verification of unique LVM disk id on each disk in the volume group /dev/vg00 failed.

You have some major problems.

> file IO Exception:java.io.IOException: I/O error

You have disk problems but there isn't much of HP-UX left for you to use:

strings not found
dd not found
etc...

Because your vg00 volume cannot be activated, /usr doesn't exist so the only commands you have are located in /sbin. This cripples any typical troubleshooting. You will probably have to use your most recent Ignite backup tape to restore the system.

Hi Shukor,

>>mv /etc/lvmtab.org /etc/lvmtab
DO NOT move lvmtab.org but move lvmtab and recreate it by "vgscan -av" as mentioned earlier.


>>sh: strings: not found
>>sh: dd: not found
Because in maintenence mode /usr will NOT be mounted.
Mount /usr and these will work.

Regds,
