well.. If you would like to check that fencing devices are properly 
configured via cluster.conf, issue fence_node NODENAME pr. node. with 
all cluster services running.

Of course, you would ideally want to do this one node at a time.

This will ensure cluster.conf has proper fencing setup and that the 
fencing devices actually work. If the node isn't locked out of the 
cluster when you issue fence_node then there is something wrong..
