OK,
         Well, I've lots of replies and the major response was:
                 1)  Drop one node of the cluster - clu_delete_member
                 2)  remove the label on the dropped members boot disk
                 3)  build the new DS20
                 4)  add the DS20 to the cluster - clu_add_member
                 5)  fail things over the to new DS20 member
                 6)  repeat for other node
         Thanks for all the replies.
         I'll post another summery after the work is done
