I took this opportunity to do what I normally do by hand when shutting 
down a node: from the other nodes, dismount the shadow set which has 
members only on the node to reboot, and for shadow sets which have some 
but not all members with direct connections to the node to reboot (I 
have only disks with direct connections to one node), dismount those 
disks from another node and create a minicopy bitmap.  That way, I don't 
have to worry about full copies or merges (haven't set up minimerge on 
system disks yet) when the node comes back up.  So, now that the 
procedure is working, I can execute it and if the node has to reboot I 
should be OK.  I just hope it doesn't pull down the cluster.  :-)
