Warning: couldn't query physical volume

[rbiorn]

Hi!

This regards a HP9000 with HP-UX 10.2

# ioscan -fnC disk
disk 8 10/0.5.0 sdisk CLAIMED DEVICE SEAGATE ST39173WC
/dev/dsk/c0t5d0 /dev/rdsk/c0t5d0


# pvdisplay -v /dev/dsk/c0t5d0
pvdisplay: Warning: couldn't query physical volume "/dev/dsk/c0t5d0":
The specified path does not correspond to physical volume attached to
this volume group
pvdisplay: Warning: couldn't query all of the physical volumes.
pvdisplay: Couldn't retrieve the names of the physical volumes
belonging to volume group "/dev/vg06".
pvdisplay: Cannot display physical volume "/dev/dsk/c0t5d0".


Naturaly the volume group is in-active, and filesystem cannot be mounted.

How can I sort this out?

first

# diskinfo -v /dev/rdsk/c0t5d0

What are the disks belonging to this VG?

# strings /etc/lvmtab

Any of them in state NO_HW?

If the lVOLS are mirrored, try

# vgchange -a y -q n vg06

if successful,

# vgdisplay -v vg06

Hi Torsten!

# diskinfo -v /dev/rdsk/c0t5d0
SCSI describe of /dev/rdsk/c0t5d0:
vendor: SEAGATE
product id: ST39173WC
type: direct access
size: 0 Kbytes
bytes per sector: 0
rev level: HP11
blocks per disk: 0
ISO version: 0
ECMA version: 0

removable media: no
response format: 2
....
#
#
# strings /etc/lvmtab
....
/dev/vg06
/dev/dsk/c0t5d0
....
So this is the only disk in this volume group


# vgchange -a y -q n vg06
vgchange: Warning: Couldn't attach to the volume group physical volume "/dev/dsk/c0t5d0":
Device busy (what is it busy about)
vgchange: Warning: couldn't query physical volume "/dev/dsk/c0t5d0":
The specified path does not correspond to physical volume attached to
this volume group
vgchange: Warning: couldn't query all of the physical volumes.
vgchange: Couldn't activate volume group "vg06":
Quorum not present, or some physical volume(s) are missing.

Your disk has gone bye bye:

# diskinfo -v /dev/rdsk/c0t5d0
SCSI describe of /dev/rdsk/c0t5d0:
vendor: SEAGATE
product id: ST39173WC
type: direct access
size: 0 Kbytes
bytes per sector: 0
rev level: HP11
blocks per disk: 0
ISO version: 0
ECMA version: 0
ANSI version: 2
removable media: no
response format: 2


size is 0 Kbytes...

You will need to replace and restore your data.


You could try shutting machine down, then pulling the disk out, then putting it back in...but I'm 99% sure your disk is no longer working...

The disk is gone:

# diskinfo -v /dev/rdsk/c0t5d0
...
size: 0 Kbytes

Replace the disk.

Thank you all!
