try something like this for the primitive:

primitive st-apc stonith:fence_apc \
	params ipaddr="xx.xx.xx.xx" login="admin" passwd="password" \
	action="reboot" port="dummy" pcmk_host_list="node1 node2" \
	pcmk_host_map="node1:1,node2:2" pcmk_host_check="static-list"

"man stonithd" and "man fence_apc" should also be helpful

corosync or heatbeat CCM do this job for Pacemaker ... deliver node
availability information so Pacemaker can calculate quorum based on node
count.
