What happens when you do a vgdisplay -v vg00? Could you possibly have the wrong disk name?

I assume that this root drive is mirrored.

Now what happens when you do a;

lvdisplay -v /dev/vg00/lvol7 | more

I would assume (if you have mirroring) that one of the disks would be stale.

Have you tried doing an lvsplit?

Hi,

After apply vgreduce, now! don't update lvmconf.

#vgcfgbackup /dev/vg00 vgcfgbackup: /etc/lvmtab is out of date with the running kernel:Kernel indicate.
Cannot proceed with backup.

Any help it's good!

Thanks

You aren't in a mirror. Hope you have a good ignite.

What do you get when you do;

vgcfgrestore -n vg00 -l

As a last resort, you could try using the vgscan command.

Try the vgscan -pv , then try doing a vgscan. You might have to rename the /etc/lvmtab file if it is corrupt.

Hi,

if you execute "lvdisplay -k" on all the lv's it will give you the pvkey value of the missing disk then execute lvreduce -k command using that key value for all the lvs. At last execute vgreduce command.
or
If lvmtab doesn't have this physical disk entry then simply execute the following command:
# vgreduce -f /dev/vg00
the above cdommand will remove the physical disks which are not listed in vg00.

I hope one of the above will definitely solve the issue.

Am I right in thinking that you have had a failed disk at some point, which you have changed but it wasn't remirrored?
This is what you could do:

First of all take out the faulted disk and don't put in a new. make sure the volume are running:
vgdisplay and lvdisplay.

Now remove the missing pv:
# vgreduce -f /dev/vg01
PV with key 1 sucessfully deleted from vg /dev/vg01

Move the existing lvmtab:
mv /etc/lvmtab /etc/lvmtab.old

Now create a new lvmtab:
# vgscan -v

Create a new vg00.conf
# vgcfgbackup vg00

**** This is here you could stop if you don't want to mirror the system again ****
**** Use "vgdisplay -v vg00" to check ****

Now you Volume consists of only one mirror and you need to remirror it agiain. So put in the new disk and do:
ioscan
insf
find the new disk and add it to the vg01
pvcreate
vgextend
lvextend -m 1 ...

Hi,

What is the outcome of the following:
# pvdisplay -v /dev/dsk/c2t6d0s2
# diskinfo -v /dev/rdsk/c2t6d0s2

Can you also sent the last 20 lines of vgdisplay -v vg00.

Should disk c2t6d0s2 be the mirror of c0t6d0s2?

Hi,

There could be several reasons for this.
1. There is no disk available at the specified path or there was a failure of the disk and after replacement there was no pvcreate and vgcfgrestore done on the disk.
Check this thread
http://forums1.itrc.hp.com/service/forums/bizsupport/questionanswer.do?threadId=980054

2. The disk device is not there or being corrupt. - is the disk c2t6d0s2 available ?
In ioscan -fnC disk - do you see this disk and does is show CLAIMED ?
If CLAIMED what does - diskinfo /dev/rdsk/c2t6d0s2 show ?

Have a look at this thread
http://forums1.itrc.hp.com/service/forums/questionanswer.do?threadId=763279

Can you try a insf -e -C disk
and then try pvdisplay -v /dev/dsk/c2t6d0s2

Ninad
