I usually use the crm shell so I'm not positive but I think these are the parts you need...


$rsc = resource to test, in your case I believe you want to specify the primitive instance of the clone i.e. p_resource:0
$task = monitor or migrate or stop or whatever operation you want to take
$interval = the interval of a monitor task
$node = the node
$rc = the exit code you want to fail with i.e. error, not_running

So (I think) something like:

You *should* be able to experiment till you get it just right since its simulate.. :-)
