It will not work. The on-disk MD superblock is written using cpu arch
format.  Furthermore, let's say you are able to re-create the raid5
array after moving it to the Sun box.  What about the filesystem and
data?  At least you need a filesystem which manipulates its metadata in
neutral format for this kind of "move" to work.
