Cant create a new volume group

[machaya chivaviro_2]

I am using an HP machine 9000 with HPUX 11.0
The sysstem has disk drives mirrored at volume group level. One of the drives which was mirrored for the file system /Vg00 crushed and was never replaced. We then had an upgrade and changed the system board and new paths were created. Right now I get this error 'Volume group could not be created" when I try to create a new volume group using any number.

If i try to recreate the lmvtab my volume group vg00 disappears and I will be able to add a new volume group but my system files are in vg00.

[Stuart Abramson]

So, you have your vg00 on the disk that was one half of the original vg00 mirror, is that right? Did you reboot your system from that disk?

Where are you trying to vgcreate the new VG? On the old mirrored drive that was replaced, or on another drive? What minor number are you using for the new VG?

[Pat Lieberg]

If you run a 'strings /etc/lvmtab' are there any other vg's listed besides vg00?

Also, are there any other vg's besides vg00 listed in the /dev directory?

[Marvin Strong]

my guess is the numbers you are picking are larger than you maxvgs kernel parameter.

check your maxvgs kernel parameter, if its 10 make sure that your using a hex number smaller than a. 0x010000 - 0x0a0000

[baiju_3]

Please post the vgcreate command and command out put .

You can try to reduce the mirror copy to 0 , ie unmirrir and then vgreduce with -f option and get rid of the failed PV .


Once this is done pls try again and post your observations.

thx,

It sounds to me like you have more than one problem. It depends on how each of those previous things were handled at the time.

Sense you have different paths now, you may have to use vgscan -av to get it to scan the disks. If you still have a phantom disk (the crashed one that was removed) in the vg you can remove it with vgreduce -f and it may come down to you having to boot in lvm management mode and exporting and importing the root vg.

You didn't specify why it wouldn't let you create a new vg so I will just list some obvious things to check till you can post back with the specific error messages and such.

Vgcreate from the command line requires you to create the vg directory /dev/vgyy and to create the group node mknod /dev/vgyy/group c 64 0x0y0000 then create the vg.

You should also run pvcreate on the new disk that you want to create the vg from to make sure its formatted correctly.

I hope that helps some

Hi,

The problem is that one disk of vg00 is missing and one disk of vg04 has been replaced but not put back to the VG.

Have you replaced /dev/dsk/c7t11d0?

Where is /dev/dsk/c6t8d0 gone?

There were extents allocated to these disks.

You can do a vgcfgrestore to /dev/c7t11d0 if you replaced it and want it to be put back in vg04.

#vgcfgrestore -n /dev/vg04 /dev/dsk/c7t11d0

Or use -R option if you wish to do this when vg is active.

Now use vgsync to sync the stale PE's.
#vgsync

Repeat to see the details.

#vgdisplay -v /dev/vg04

The same thing can be repeated slight differently for rootvg also but your disk at the path is missing still.


HTH,
Devender
