fence_rsa is an I/O Fencing agent which can be used with the IBM RSA II management interface. It logs into an RSA II device via telnet and reboots the associated machine. Lengthy telnet connections to the RSA II device should be avoided while a GFS cluster is running because the connection will block any necessary fencing actions.

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