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.
