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

Did ioscan -fnC disk , shows you the disk path is claimed ?

[S-M-S]

Hi Fizan,

What is your OS version?

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

[fizan]

disk also dosen't looks bad.

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

[Torsten.]

Please do the same for partition 2:

# diskinfo -v /dev/rdsk/c2t1d0s2

[S-M-S]

Try this

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

[fizan]

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?

[S-M-S]

Be sure that you are using currect syntax

#vgextend vg00 /dev/dsk/c2t1d0s2

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

[fizan]

tortsen i followed the pdf it looks the steps performed are similar.

[Michal Kapalka (mikap)]

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

vgextend /dev/vg00 /dev/dsk/c4t0d0s2

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

....
lvextend -m 1 /dev/vg00/lvol(x) /dev/dsk/c4t0d0s2
lvlnboot -r /dev/vg00/lvol3 /dev/vg00

lvlnboot -s /dev/vg00/lvol2 /dev/vg00
lvlnboot -d /dev/vg00/lvol2 /dev/vg00

Can you append a "vgdisplay -v vg00" ?

No, they are not, based on what you posted.

tortsen let me try again as in the pdf.

[R.O.]

The second disk appears as "unavailable". You might activate it with "pvchange -a y /dev/dsk/c2t1d0s2"

[Michal Kapalka (mikap)]

hi,

your OS is HP-UX 11.31, i would recomend use only one type of disk, legasy or agile not both.
