vgmerge.  You need to have the source VG with all your LVs inactive
and the PE size must be the same in both VGs.


Basically this would be:

lvchange -a n /dev/vg02/lv01
lvchange -a n /dev/vg02/lv02
lvchange -a n /dev/vg02/lv03
...
vgmerge vg01 vg02
vgchange -ay


this would put all the LVs from vg02 into the vg01 VG.
