If your wanting to add a new disk to the same volume
group and use it then no you don't need to rename
anything, you can use the vgextend command after
running pvcreate on the new disk to extend the
existing volume group to the new disk.

If your wanting to add an existing disk to a system
that already has a conflicting volume group name in
it, then yes you'll need to vgrename one of them so
they do not conflict.
