vgdisplay: Warning: couldn't query all of the physical volumes.

[Glenn Mitchell_4]

D220 server running hp-ux 10.20. A mirrored drive went bad and was replaced.
c3t8d0 was mirrored to c3t12d0(one that went bad). I was out when this happened, so I'm not sure what happened as far as steps or commands entered between the time the drive went bad and was replaced.

I wanted to re-mirror the drive, but when I do a vgdisplay on the VG I get:

rockcc # vgdisplay -v vg02
vgdisplay: Warning: couldn't query physical volume "":
The specified path does not correspond to physical volume attached to
this volume group
vgdisplay: Warning: couldn't query all of the physical volumes.

I tried to copy off the /etc/lvmtab and running vgscan -v to no avail.
What should I do/try?

after you replace the drive you should vgcfgrestore lvmconf to the replaced disk - strings /etc/lvmtab
and attach the full vgdisplay output in a text file attachment.

The snipit of the syslog would be useful too.

Is it possible nothing happened?

First confirm the drive in fact was replaced.
Then try restoring the disk to the volume group and resync it.

vgcfgrestore -n /dev/vg /dev/dsk/c3t12d0
vgchange -a y /dev/vg
vgsync /dev/vg

Just a quick thought,

Looks like one physical volume isn't up.

You may just need to resynch your mirrors.

Or.

post up a dmesg command and lets see if we still have lbolts.

If you have swapped out a hotswap drive, you will have an lbolt command until next boot.

This behavior may indicate a dead, unused drive in the drive cage, if these drives are internals in a drive cage.

It also might indicate a bad drive cage, which directs power and bandwidth to and from internal drives in many classes of server.

Unlikely, but a scsi cable could be causing trouble or even a scsi card.

Good luck,

I'd be happy to look at some diagnostics.

Run vgcfgrestore -n /dev/vg02 /dev/rdsk/dskname ,
Run this command on mirror disk too.

vgchange -a y /dev/vg02 (to activate vg)
