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 https://github.com/sammcj/fence_rcd_serial Fencing action Method to fence Port of the serial device Disable logging to stderr. Does not affect --verbose or --debug-file or logging to syslog. Verbose mode. Multiple -v flags can be stacked on the command line (e.g., -vvv) to increase verbosity. 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). Write debug information to given file Write debug information to given file Display version information and exit Display help and exit Separator for plug parameter when specifying more than 1 plug Wait X seconds before fencing is started Disable timeout (true/false) (default: true when run from Pacemaker 2.0+) Wait X seconds for cmd prompt after login Test X seconds for status change after ON/OFF Wait X seconds after issuing ON/OFF Wait X seconds for cmd prompt after issuing command Sleep X seconds between status calls during a STONITH action Count of attempts to retry power on
