You do not need it because LVM already should do this on its own.

vgscan scans all physical devices and creates its own map in
/etc/lvmtab. With LVM block devices have symbolic names 
(/dev/vg00/lvol1) and the physical devices are discovered/associated 
by their VGDA during vgscan. The physical address should not really 
matter.

I did not actually try this but it should work.
