Fence Agents for Red Hat Cluster - WTI Network Power Switch agent

 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_wti is an I/O Fencing agent which can be used with the WTI Network Power
 Switch (NPS). It logs into an NPS via telnet or ssh and boots a specified plug.
 Lengthy telnet connections to the NPS should be avoided while a GFS cluster is
 running because the connection will block any necessary fencing actions.
