7 fence_apc - Fence agent for APC over telnet/ssh
8
10 fence_apc is an I/O Fencing agent which can be used with the APC net‐
11 work power switch. It logs into device via telnet/ssh and reboots a
12 specified outlet. Lengthy telnet/ssh connections should be avoided
13 while a GFS cluster is running because the connection will block
14 any necessary fencing actions.
15
16 fence_apc accepts options on the command line as well as from stdin.
17 Fenced sends parameters through stdin when it execs the agent.
18 fence_apc can be run by itself with command line options. This is use‐
19 ful for testing and for turning outlets on or off from scripts.
