How to: fencing in 2 nodes cluster with iLO 4?

I have configure a 2 node (master/slave) cluster on HP GL360p servers with iLO 4. OS is centos 7 and I am using pcs with pacemaker and corosync. I want to implement fencing but I can't find any documents about how to get started with it. My requirement are simple: if one of the node becomes unavailable the other reboots it through its iLO interface. And I cant buy additional hardware for this test setup at this stage.
