Red Hat Fence Agents is a collection of scripts to handle remote power management for several devices. They allow failed or unreachable nodes to be forcibly restarted and removed from the cluster.

fence_cyberpower_ssh is an I/O Fencing agent which can be used with the CyberPower network power switch. It logs into device via ssh and reboots a specified outlet. Lengthy ssh connections should be avoided while a GFS cluster is running because the connection will block any necessary fencing actions.
