I think you mean assemble instead of build. If I follow your meager description of the issue correctly this should work. You can move a softraid volume to another machine and it should auto assemble. The trick is to have all pieces in good shape. A dmesg might help because a disk that wasn't auto assembled will complain (unless it was deleted).
