I have been looking at STONITH examples on the web and am somewhat confused.
I can't figure out how STONITH knows how to kill an individual server. I've
been looking at some examples such as this one. How does heartbeat know
that this will shut off node01. I see the nodename set to node01, but does
that do it?
