If this is a release 1 (non-CRM) cluster, then the advice below is 
correct...

If you have it as the last resource in the resource group, it will be 
run last.

See http://linux-ha.org/HeartbeatResourceAgent for details.

If you want to make this an OCF resource agent (for a release 2 style 
cluster), it's similar but slightly more involved.
