Why not use the classic approach: "dd if=old_disk of=new_disk" or something such?
Create a new LUN of exactly the same size as the old one, create a VG and mount it on the first machine, create the copy with simple UNIX means, for example:
Then unmount and export the VG. Change the zoning to allow access from the second machine (and maybe disallow access from the originating one) and import the VG.
Hi,
