vgcfgbackup - backup volume group descriptor area
vgcfgbackup [-d|--debug] [-f|--file filename] [-h|--help] [--ignorelockingfailure] [-P|--partial] [-v|--verbose] [VolumeGroupName...]
vgcfgbackup allows you to backup the metadata of your volume groups. If you don't name any volume groups on the command line, all of them
will be backed up.
In a default installation, each volume group gets backed up into a separate file bearing the name of the volume group in the directory
/etc/lvm/backup. You can write the backup to an alternative file using -f. In this case if you are backing up more than one volume group
the filename is treated as a template, and %s gets replaced by the volume group name.
NB. This DOESN'T backup user/system data in logical volume(s)! Backup /etc/lvm regularly too.
See lvm for common options.

vgcfgrestore - restore volume group descriptor area
vgcfgrestore [-d|--debug] [-f|--file filename] [-l[l]|--list] [-h|--help] [-M|--Metadatatype1|2] [-t|--test] [-v|--verbose] VolumeGroupName
vgcfgrestore allows you to restore the metadata of VolumeGroupName from a text backup file produced by vgcfgbackup. You can specify a
backup file with --file. If no backup file is specified, the most recent one is used. Use --list for a list of the available backup and
archive files of VolumeGroupName.
OPTIONS -l | --list -- List files pertaining to VolumeGroupName
List metadata backup and archive files pertaining to VolumeGroupName. May be used with the -f option. Does not restore Vol-
-f | --file filename -- Name of LVM metadata backup file
Specifies a metadata backup or archive file to be used for restoring VolumeGroupName. Often this file has been created with vgcfg-
See lvm for common options.
REPLACING PHYSICAL VOLUMES
vgdisplay --partial--verbose will show you the UUIDs and sizes of any PVs that are no longer present. If a PV in the VG is lost and you
wish to substitute another of the same size, use pvcreate --restorefile filename --uuid uuid (plus additional arguments as appropriate) to
initialise it with the same UUID as the missing PV. Repeat for all other missing PVs in the VG. Then use vgcfgrestore --file filename to
restore the volume group's metadata.

Not real Linux expert but here is the problem.

Suppose I have 3 disks c0t0d0, c0t0d1, and c0t0d2 all with the *same* VGID.
I then run:
# vgchgid /dev/rdsk/c0t0d0 /dev/rdsk/c0t0d1
(notice I *accidentally* skipped the third disk!)
How would I fix this so that all 3 disks have the same VGID again?
