[Pacemaker] Cluster proxy pacemaker-corosync in a BladeCenter

[victor]

I already had rode the Tim Serong's page. It's good.

If I don't start the cluster at boot time and I set stonith-action to poweroff 
instead of reboot, it's run if a service down or a node not respond but if the 
connection between nodes is down, power off each other also.
The problem is when the two nodes are live but not communication between them.
