FENCE_AGENT(8) System Manager's Manual FENCE_AGENT(8)

NAME

fence_rcd_serial - rcd_serial fence agent

DESCRIPTION

fence_rcd_serial operates a serial cable that toggles a reset of an opposing server using the reset switch on its motherboard. The cable itself is simple with no power, network or moving parts. An example of the cable is available here: https://smcleod.net/rcd-stonith/ and the circuit design is available in the fence-agents src as SVG

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