hi,

check if you have created the special device :

hope you made this structure on the disk :

EFI 500MB
HPUX 100%
HPSP 400MB

if not try to run insf -eC disk

ioscan -fnC disk

ll /dev/rdsk/c2t1d0s2

Hi Fizan,

What is your OS version?

Is it a local disk or a LUN presented from a storage ?

Hi Fizan,
Please confirm that the divise file associated with this disk is not there in /etc/lvmtab

which version of OS is this ?

Try
#pvcreate -B /dev/rdsk/c2t1d0s2

Re: root miirroring error

Torsten. — Thu, 22 Apr 2010 06:11:43 GMT

Please do the same for partition 2:

# diskinfo -v /dev/rdsk/c2t1d0s2

Re: root miirroring error

S-M-S — Thu, 22 Apr 2010 06:13:02 GMT

Try this

#pvcreate -f -B /dev/rdsk/c2t1d0s2

solution:
when i gave insf -e -H 0/1/1/0.1.0 no reaction.

next in general insf -e--- recreted for all

pvcreate -f -B c2t1d0s2... done but now

vgextend says that no such group file or directory is there?

Be sure that you are using currect syntax

For mirroring boot disks see appendix in

http://docs.hp.com/en/5991-1236/When_Good_Disks_Go_Bad_WP.pdf

Make sure to use the new device files, e.g.

/dev/disk/disk5

hi,

in you case i would make it from scratch.

if i need to mirrorthe disks on HP-UX 11.23 use this procedure for many years :

#==============================================

/tmp/mirror_part1.sh - preparing the disk for mirroring and extend the VG
/tmp/mirror_part2.sh - exltend the LV-s and finish the mirroring process

Primary disk : /dev/rdsk/c0t0d0 ( source )

Secondary disk : /dev/rdsk/c4t0d0 ( destination - disk for extending / mirroring )

Content of "partitionfile"

3
EFI 500MB
HPUX 100%
HPSP 400MB

#=====================================================
# /tmp/mirror_part1.sh ( phase1 )
#=====================================================

set -x
idisk -wf /tmp/partitionfile /dev/rdsk/c4t0d0
insf -e
pvcreate -B -f /dev/rdsk/c4t0d0s2
mkboot -e -l /dev/dsk/c4t0d0
vgextend /dev/vg00 /dev/dsk/c4t0d0s2

#=====================================================
# /tmp/mirror_part2.sh ( phase2 )
#=====================================================
set -x
lvextend -m 1 /dev/vg00/lvol1 /dev/dsk/c4t0d0s2
lvextend -m 1 /dev/vg00/lvol2 /dev/dsk/c4t0d0s2
lvextend -m 1 /dev/vg00/lvol3 /dev/dsk/c4t0d0s2
lvextend -m 1 /dev/vg00/lvol4 /dev/dsk/c4t0d0s2
....
lvextend -m 1 /dev/vg00/lvol(x) /dev/dsk/c4t0d0s2
lvlnboot -r /dev/vg00/lvol3 /dev/vg00
lvlnboot -b /dev/vg00/lvol1 /dev/vg00
lvlnboot -s /dev/vg00/lvol2 /dev/vg00
lvlnboot -d /dev/vg00/lvol2 /dev/vg00
efi_ls -d /dev/rdsk/c4t0d0s1
echo "boot vmunix -lq" > /tmp/AUTO.lq

Can you append a "vgdisplay -v vg00" ?
