sysctlrd(1M)							  sysctlrd(1M)

NAME    [Toc]    [Back]

     sysctlrd -	communicates with the system controller	and LCD	front panel on
     Onyx/Challenge L/XL systems

SYNOPSIS    [Toc]    [Back]

     /usr/etc/sysctlrd -d [ -g ] [ -n ]	[ -v ] | -p

DESCRIPTION    [Toc]    [Back]

     sysctlrd can be run as a user command or as a daemon run by
     /etc/rc2.d/S33sysctlr.  It	handles	all necessary communications with an
     Onyx or Challenge L/XL system's system controller,	which controls power
     sequencing	and fan	speed, monitors	system sensors,	and drives the LCD
     front panel.  sysctlrd runs the cpu activity histogram on the front
     panel, retrieves environmental sensor data, and handles warning and alarm
     messages from the system controller.  sysctlrd also logs configuration
     error messages from the PROM in /var/adm/SYSLOG (see syslog(3C)).

     The options are:

     -d	  Daemon mode.	Only one sysctlrd can run as a daemon at a time, and
	  it must be run as root.

     -g	  Graceful powerdown mode (only	works with -d).	 sysctlrd sends	a
	  hang-up signal to all	processes, waits two seconds, sends a kill
	  signal to all	processes, syncs all disks, and	then powers the	system

     -n	  No CPU meter mode (only works	with -d).  Keeps sysctlrd from sending
	  CPU performance information to the LCD front panel.

     -v	  Give more verbose output.

     -l	  Logging of VDC extrema changes from all of the power supplies	when
	  run in VDC variance logging mode. (e.g. the "-l" option is passed to
	  sysctlrd from	/etc/init.d/sysctlr). This is useful if	you are
	  collecting lots of information to debug and/or analyze a problem
	  which	you believe may	be related to power surges and/or hardware
	  failures. Please contact SGI technical support in the	event that
	  there	is some	problem	which you believe needs	their attention.

     -p	  Print	sensor information (does not work with -d).  This option
	  causes sysctlrd to query the daemon for system controller sensor
	  information and print	it in a	human-readable format.

DIAGNOSTICS    [Toc]    [Back]

     "*** ..." messages	are PROM configuration messages	logged by sysctlrd.

     Messages of the form "Event: date time: ..." are retrieved	directly from
     system controller log RAM.	 These may hold	information about when and why
     the system	was shut down previously.  Note	that the times listed are from
     the system	controller's internal clock.  This clock is set	at each
     invocation	of sysctlrd with the -d	option,	and it runs freely from	then

     on.  The clock has	no concept of alternate	timezones.  Some examples of
     informational messages that may be	logged are:

     SCLR DETECTED   The system	was reset from the front panel or rebooted via
		     a UNIX command.

     SYSTEM OFF	     The system	was powered-off	from the front panel.

     SYSTEM ON	     The system	was powered-on from the	front panel.

     NMI	     Someone selected NMI (nonmaskable interrupt) from the
		     front panel.

     "Couldn't open /dev/sysctlr. Exiting" is printed to standard error	if the
     daemon cannot open	the system controller device driver.  It usually means
     that a daemon is already running.

     "Get env info failed" is logged if	sysctlrd is unable to get the sensor
     information after retries.

     "Get scale	failed!	 Assuming small	panel" is logged if sysctlrd cannot
     get the LCD panel size.  On Onyx/Challenge	XL systems, this results in
     very short	CPU performance	bars since they	are improperly scaled.

     "Get log failed!" is logged if sysctlrd cannot retrieve the system
     controller	event log containing such events as system resets, power
     fails, voltage problems, overheating, and so on.

     "Can't contact daemon. Exiting" is	printed	to standard error if a nondaemon
 invocation of sysctlrd cannot contact the daemon to	retrieve
     information.  The daemon may have died or may not have been able to set
     up	its IPC.

     "Giving up	on fetching environmental information" is logged if sysctlrd
     fails to retrieve environment information 20 times	in succession.	Nondaemon
 invocations	cannot retrieve	information after this happens.

     "Overtemp alarm!" is printed to standard error when the system controller
     sends an overtemp message.	 This system is	shut down automatically	at
     this point, syncing disks if graceful powerdown is	active.

     "Keyswitch	off!" is printed to standard error when	the key	is switched
     off with sysctlrd running.	 This system is	shut down, syncing disks if
     graceful powerdown	is active.

     "Blower failure!" is printed to standard error if the system controller
     detects a failure in one of the system's fans.  The system	is powereddown

     "Voltage out of tolerance!" is logged if the system controller detects a
     voltage that is out of tolerance but not yet dangerous to the system.

     "Firmware compensating for	blower RPM problem" is logged if the system
     controller	must compensate	for a blower speed problem by requesting a
     higher blower speed.

     "System controller	firmware reset"	is logged if the system	controller
     firmware detects an internal error	and resets itself.  This message is
     only indicative of	a problem if it	is logged repeatedly.

     "COP timer	reset error!" is logged	if the system controller internal
     timer detects hung	firmware.  Again, this message is only indicative of a
     problem if	it is logged repeatedly.

     "System controller	crystal	oscillator failed!" is logged if the system
     controller	detects	a problem with its own oscillator.

     The system	controller will	send a warning message when it measures	an RPM
     higher than the upper tolerance.  Normally	this message is	sent
     immediately after the system controller powers up (this is	only for the
     systems that have the 2700	RPM blower installed).	Sometimes, the blower
     sends out bad RPM data.  The measurement data shows RPM values > 28000
     RPM.  In cases such as these, it has been determined that the tach	pulse
     from the blower has noise on it, which causes these incorrect high
     readings.	Some blower(s) checked were actually spinning near 1400	RPM
     when they were reporting an RPM value of 27K.  Now, the system controller
     monitors for this condition and if	a reading is posted by the system
     controller	> 3000 RPM, a notification message will	be posted as a warning
     in	both the SYSLOG	and on the console at the first	occurrence of such an
     event and at intervals of one hour	thereafter (if the condition
     persists).	Please contact SGI technical support in	the event that you
     constantly	receive	such a message from the	system controller.

     Note: running the system controller daemon	with verbose mode on (-v) will
     generate a	large amount of	output in the system logfile and should	only
     be	used when debugging hardware configurations.
