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

NAME

       fence_rsb - I/O Fencing agent for Fujitsu-Siemens RSB

SYNOPSIS

       fence_rsb [OPTION]...

DESCRIPTION

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

       fence_rsb  accepts  options  on	the  command  line  as well as from stdin.  Fenced sends parameters through stdin when it execs the agent.
       fence_rsb can be run by itself with command line options.  This is useful for testing.

       Vendor URL: http://www.fujitsu.com

OPTIONS

       -a IPaddress
	      IP address or hostname of the RSB device.

       -h     Print out a help message describing available options, then exit.

       -l login
	      Login name.

       -n telnet_port
	      The port number on which the telnet service listens.

       -o action
	      The action required.  This can be reboot (default), off, on, or status.

       -p password
	      Password for login.

       -S path
	      Full path to an executable to generate the password for login.

       -v     Verbose.	Print informational messages to standard out.

       -V     Print out a version message, then exit.

STDIN PARAMETERS
