The xfnts_monitor_stop Method

Because the xfnts_monitor_start method uses scds_pmf_start to start the monitor daemon under PMF, xfnts_monitor_stop uses scds_pmf_stop to stop the monitor daemon.

The first call in xfnts_monitor_stop is to scds_initialize, which performs some necessary house-keeping functions (see "The scds_initialize Call" and the scds_initialize(3HA) man page for details.

The xfnts_monitor_stop method calls the mon_stop method, which is defined in xfnts.c as follows.

Example 7-13

	scds_syslog_debug(DBG_LEVEL_HIGH,
		"Calling scds_pmf_stop method");

	err = scds_pmf_stop(scds_handle, SCDS_PMF_TYPE_MON,
	    SCDS_PMF_SINGLE_INSTANCE, SIGKILL,
	    scds_get_rs_monitor_stop_timeout(scds_handle));

	if (err != SCHA_ERR_NOERR) {
		scds_syslog(LOG_ERR,
		    "Failed to stop fault monitor.");
		return (1);
	}

	scds_syslog(LOG_INFO,
	    "Stopped the fault monitor.");

	return (SCHA_ERR_NOERR); /* Successfully stopped monitor */
}

Note the following about the call in svc_mon_stop to the scds_pmf_stop function.

• SCDS_PMF_TYPE_MON parameter identifies the program to stop as a fault monitor--this method can also stop a data service or some other type of application.

• The SCDS_PMF_SINGLE_INSTANCE parameter identifies this as a single-instance resource.

• The SIGKILL parameter identifies the signal to use to stop the resource instance. If this signal fails to stop the instance, scds_pmf_stop returns with a timeout error. See the scds_pmf_stop(3HA) man page for details.

• The timeout value is that of the Monitor_stop_timeout property of the resource.

Before it exits, the xfnts_monitor_stop method calls scds_close to reclaim resources allocated by scds_initialize. See "The scds_initialize Call" and the scds_close(3HA) man page for details.
