[Pacemaker] How to disallow resources to re-run after they were stopped

[Mistina Michal]

Dear all.

I am using ping resource agent to check if the resources can run on the
node. I have 2 node cluster.

If the destination is down resources are also down on that particular node.
If the destination can be pinged again the resources boot again on the node.

My question is, how can I achieve the node which once couldn't ping the
destination is marked as the host where the resources cannot run anymore, so
the resources stay in stopped state?

OS: RHEL 6.3
