NAME
     fence_crosslink - Fence agent for cross-link two-node clusters

DESCRIPTION
     This  agent  helps two-node clusters to tackle the situation where one node
     lost power, cannot be fenced by telling pacemaker that if the node  is  not
     reachable over the crosslink cable, we can assume it is dead

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

PARAMETERS

     -o, --action=[action]
	    Fencing action (Default Value: reboot)

     -a, --crosscableip=[IP]
	    Cross-cable IP This parameter is always required.

     -n, --plug=[id]
	    Physical plug number on device, UUID or  identification  of  machine
	    This parameter is always required.

     -T, --timeout=[seconds]
	    No	ICMP  reply  in  5  seconds  -> Node is considered dead (Default

	    Disable logging to stderr. Does not affect --verbose or --debug-file
	    or logging to syslog.

     -v, --verbose

	    (e.g., -vvv) to increase verbosity.

     --verbose-level
	    Level  of  debugging  detail  in  output.  Defaults to the number of
	    --verbose flags specified on the command line, or to 1 if  verbose=1
	    in a stonith device configuration (i.e., on stdin).

     -D, --debug-file=[debugfile]
	    Write debug information to given file

     -V, --version
	    Display version information and exit

     -h, --help
	    Display help and exit

     --plug-separator=[char]
	    Separator  for  plug parameter when specifying more than 1 plug (De-
	    fault Value: ,)

     -C, --separator=[char]
	    Separator for CSV created by 'list'  operation  (Default  Value:  ,)

     --delay=[seconds]
	    Wait X seconds before fencing is started (Default Value: 0)

     --disable-timeout=[true/false]
	    Disable  timeout (true/false) (default: true when run from Pacemaker
	    2.0+)

     --login-timeout=[seconds]
	    Wait X seconds for cmd prompt after login (Default Value: 5)

     --power-timeout=[seconds]
	    Test X seconds for status change after ON/OFF  (Default  Value:  20)

     --power-wait=[seconds]
	    Wait X seconds after issuing ON/OFF (Default Value: 0)

     --shell-timeout=[seconds]
	    Wait  X seconds for cmd prompt after issuing command (Default Value:
	    3)

     --stonith-status-sleep=[seconds]
	    Sleep X seconds between status calls during a  STONITH  action  (De-
	    fault Value: 1)

     --retry-on=[attempts]
	    Count of attempts to retry power on (Default Value: 1)

     status
	    This returns the status of the plug/virtual machine.

     list   List  available plugs with aliases/virtual machines if there is sup-
	    port for more then one device. Returns N/A otherwise.
