What EFI does with a clone is indeterminate — hopefully you get an 
error, but I would not bet on it.   EFI requires all partitions to have 
unique GUIDs, so the case of multiple identical copies "should not 
happen".

If the disk image starts from a DVD, then the result of the COPY will 
not be bootable on OpenVMS.  You will first have to reset the boot 
block data structures with a SET BOOTBLOCK command.
