NAME

       fence_apc - Fence agent for APC over telnet/ssh

DESCRIPTION

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

       fence_apc  accepts  options  on	the  command  line  as	well as from stdin. Fenced sends parameters through stdin when it execs the agent.
       fence_apc can be run by itself with command line options.  This is useful for testing and for turning outlets on or off from scripts.
