   It is possible to shut down the Alphas with /remove_node, so that
   the remaining Itanium systems in the cluster can continue.  Normally
   when the Alphas come back up, they rejoin the existing cluster.

   If the network goes down while the Alphas are down, and the Alphas
   have enough votes, it is possible to bring them back up as a separate
   cluster.  When network connections are restored, I'd expect some of
   the nodes may CLUEXIT to avoid inconsistent state.

   In the meantime, disk shadowning is down and at least one of the
   two separate clusters should not have access to the shadowed disks 
   unless a privileged user is foolish enough to break it.

   And this doens't really have anthing to do with Alpha vs. Itanium,
   that's just the geography the OP appearently has.
