I don't think so. One of the major points of LVM is that volumes can span
physical disks and you can transparently add disks to the systems and grow
existing LVs over them.

To merge two Volume Groups, try the "vgmerge" command. The only prerequisite is
that they have the same PE size (which is set at vgcreate time).
