Hi Piyut,

Something must have gone wrong. What happened before this error started?

Give us the o/p of
i) "ioscan -fnC disk"
ii) "diskinfo /dev/rdsk/c0t6d0"
iii) "pvdisplay -v /dev/dsk/c0t6d0"
iv) "ll /dev/(r)dsk/*"

Did u try "vgcfgrestore"?

The message
"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/c4t0d3
/dev/dsk/c5t0d3"
indicates that these two devices were not included in any of the volumes, while "strings /etc/lvmtab" whows them to be the part of VG03.

Provide us the above o/p.

strings /etc/lvmtab

ioscan -fnC disk

See if those disks are all present in ioscan.

A possible cause is that a disk failed and vg00 can't be activated due to quorum not being present.

dears,

Before I run vgscan -a , I mv /etc/lvmtab to /etc/lvmtab.ori
I want to remove VG04 but i can't do it before.
file /etc/lvmtab.ori:

# strings /etc/lvmtab.ori
/dev/vg00
/dev/dsk/c3t6d0
/dev/dsk/c0t6d0
/dev/vg01
/dev/dsk/c4t0d0
/dev/dsk/c5t0d0
/dev/vg02
/dev/dsk/c4t0d1
/dev/dsk/c5t0d1
/dev/vg03
/dev/dsk/c4t0d2
/dev/dsk/c5t0d2
/dev/vg04
/dev/dsk/c4t0d3
/dev/dsk/c5t0d3

I removed VG04 and extend VG03.Before do this, I run "vgscan -a" and have errors.

# strings /etc/lvmtab
/dev/vg01
/dev/dsk/c4t0d0
/dev/dsk/c5t0d0
/dev/vg02

Condition of my server running normally, now. (without VG00 at /etc/lvmtab)

Re: missing vg00 at /etc/lvmtab

Suraj Singh_1 — Fri, 27 May 2005 02:38:23 GMT

Hi Piyut,

Issue "#vgcfgrestore -n /dev/vg00 -l" command and see if you can see the 2 disks c0t6d0 & c3t6d0 in the o/p.

If yes, you would need to restore vg00 using vgcfgrestore.

# vgcfgrestore -R -n /dev/vg00 /dev/rdsk/c3t6d0 /dev/rdsk/c0t6d0

Then run "vgscan -v"

Regards,

Hi piyut,

from ur second response..i think you moved the lvmtab to lvmtab.ori and deleted vg04 and extended vg03. Is this what you meant, could you clarify further, from first.. what you did before you ran into errors...with vgscan -a.

Thanx

dear kumar,

u right, i move /etc/lvmtab to /etc/lvmtab.ori.
before do that, i try to remove vg04 but i can't.i forgot what i did..sorry.i remember, i remove /dev/vg04/group and than i make mknod /dev/dsk/vg04.

Re: missing vg00 at /etc/lvmtab

Senthil Kumar .A_1 — Sun, 29 May 2005 22:09:19 GMT

Hi Piyut,

Please remember, all LVM commands update /etc/lvmtab , after it finishes the action .Since you moved /etc/lvmtab , thats the reason you couldn't remove vg04, or perform any lvm actions.

To recover

1) copy lvmtab.ori to /etc/lvmtab.
2) Remove vg04 using umount,lvremove and vgreduce and then by vgremove. (never remove group file before you have done this).follow the below procedure.

a) umount all the FS using LV's from vg04.
mount | grep -i vg04.
umount /dev/vg04/lv(nn).

b) vgdisplay to see how many PV are there in it.

vgdisplay -v vg04

c) remove all the PV leaving only one.

vgreduce /dev/vg04

d) vgremove vg04 (remove the VG vg04)

3) Then you can proceed adding vg03

a) mkdir /dev/vg03
b) ll /dev/vg*/group
c) use the next minor number which is in sequence.
mknod /dev/vg03/group c 64 0xnn0000
where nn , is the next number in sequence to command shown in step 3.b

d)pvcreate /dev/rdsk/cXtYdZ
e)vgcreate /dev/vg03 /dev/rdsk/cXtYdZ
f)lvcreate -L vg03
g)newfs -F /dev/vg03/rlvolX
h)mkdir
i) mount /dev/vg03/lvolX

n,X,Y,Z are numbers that you many get from commands specific to your machine. I have generalized.

The errors your are getting because it coudn't find /etc/lvtab file as you had moved it orior to your actions.

I hope this helps.

Regards.

In /etc/lvmtab, there is no vg00. this will be make me trouble if we reboot this server.

Hi piyut ,

from ur previous response i found this..

# vgcfgrestore -n /dev/vg00 -l
Volume Group Configuration information in "/etc/lvmconf/vg00.conf"
VG Name /dev/vg00
---- Physical volumes : 2 ----
/dev/rdsk/c3t6d0 (Bootable)
/dev/rdsk/c0t6d0 (Bootable)
# vgcfgrestore -R -n /dev/vg00 /dev/rdsk/c3t6d0 /dev/rdsk/c0t6d0
Usage: vgcfgrestore
[-R]
[-F]
{ -n vgname |
-f VGConfPath }
{ -l |
{[-o OldPVPath] PVPath}}
OldPVPath and PVPath : character special files

anything else ?

Please remember, the response from the command shows that you have made a systax error.

You can't give two raw device file at the end to "vgcfgrestore". you need to give one at a time.

# vgcfgrestore -R -n /dev/vg00 /dev/rdsk/c3t6d0

# vgcfgrestore -R -n /dev/vg00 /dev/rdsk/c0t6d0

Then check,

pvdisplay -v /dev/dsk/c3t6d0 | more
pvdisplay -v /dev/dsk/c0t6d0 | more

If it has indeed restored...

Then,move current lvmtab to /tmp/lvmtabtmp

Then issue the command

vgscan -a

Then check, whether vg00 is restored to lvtab.

#strings /etc/lvmtab

Regards.
