vgcfgbackup error

Hi Gurus,

I am able to access the LV but unable to take the vgcfgbackup,

# vgcfgbackup vg21

How can I take the vgcfgbackup of this VG?

Thanks.

Hiya,

LVM thinks there should be a bunch of disks in this VG, but there seems to be only one inthere. (Cur PV 1)

# vgdisplay -v vg21

--> will show you which disk is actually inthere.

Is this a new (empty) volume group ?

Cheers,
Wout

Why cant I deactivate the VG?
How come its going busy? I have checked none of the processes involve this VG.

[Wouter Jagers]

Ahh, you (are supposed to) have 8 paths to your disk, that makes sense.

Is your logical volume mounted ? Make sure it's unmounted before trying to deactivate.

It seems like none of your alternate links (still) exist, check if you can reach them with, for example:

# diskinfo /dev/rdsk/c17t0d1

The output of "ioscan -fnCdisk" could also be useful to check.

Cheers,

You can use vgimport and vgexport utilty.

[Shomsa]

Check the filesystem is mounted .umount vgexport and vgimport. Before that what is the disk details in lvmtab
