The VG name is stored in the ODM, not on a disk. On the disk is only the VGDA which has the VGID stored.

You can use the following to read the VGDA before importing it:
Code:
lqueryvg -tcAp <hdisk>

It reads all information about the VGDA directly from the disk.

There is a part starting with "Logical:" which shows the LVs on this disk. The long number is the VGID, at least the part before the dot.

Why do you need to use the VG name from the former disk? To check the contents of the disk you could always import it with any name but a VG name that already exists.

NAME
vgcfgbackup - backup volume group descriptor area SYNOPSIS
vgcfgbackup [-d|--debug] [-f|--file filename] [-h|--help] [--ignorelockingfailure] [-P|--partial] [-v|--verbose] [VolumeGroupName...] DESCRIPTION
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. OPTIONS
See lvm for common options. SEE ALSO
