RASDAEMON(8)						RAS memory controller admin utility					      RASDAEMON(8)

NAME

       rasdaemon - RAS daemon to log the RAS events.

SYNOPSIS

       rasdaemon [OPTION]...

DESCRIPTION

       The rasdaemon program is a daemon with monitors the RAS trace events from /sys/kernel/debug/tracing, reporting them via syslog/journald.

OPTIONS

       --usage
	      Display a brief usage message and exit.

       --help Display a help message and exit.

       --disable
	      Disable RAS tracing events and exit.

       --enable
	      Enable RAS tracing events and exit.

       --foreground
	      Executes	in  foreground,  printing the events at console. Useful for testing it, and to be used by systemd or Unix System V respan.
	      If not specified, the program runs in daemon mode.

       --version
	      Prints the program version and exit.

NAME

       ras-mc-ctl - RAS memory controller admin utility

SYNOPSIS

       ras-mc-ctl [OPTION]...

DESCRIPTION

       The  ras-mc-ctl	program  is  a perl(1) script which performs some useful RAS administration tasks on EDAC (Error Detection and Correction)
       drivers.

OPTIONS

       --help Display a brief usage message.

       --mainboard
	      Print mainboard vendor and model for this hardware, if available.  The method used by ras-mc-ctl to obtain the mainboard vendor  and
	      model information for the current system is described below in the MAINBOARD CONFIGURATION section.

       --status
	      Print the status of EDAC drivers (loaded or unloaded).

       --quiet
	      Be less verbose when executing an operation.

       --register-labels
	      Register	motherboard DIMM labels into EDAC driver sysfs files.  This option uses the detected mainboard manufacturer and model num-
	      ber in combination with a "labels database" found in any of the files under /etc/ras/dimm_labels.d/* or in  the  labels.db  file	at
	      /etc/ras/dimm_labels.db. An entry for the current hardware must exist in the labels database for this option to do anything.

       --print-labels
	      Display the configured labels for the current hardware, as well as the current labels registered with EDAC.

       --guess-labels
	      Print DMI labels, when bank locator is available at the DMI table.  It helps to fill the labels database at /etc/ras/dimm_labels.d/.

       --labeldb=DB
	      Specify an alternate location for the labels database.

       --delay=time
	      Specify a delay of ime seconds before registering dimm labels.  Only meaninful if used together with --register-labels.

       --layout
	      Prints  the  memory  layout as detected by the EDAC driver. Useful to check if the EDAC driver is properly detecting the memory con-
	      troller architecture.

MAINBOARD CONFIGURATION

       The ras-mc-ctl script uses the following method to determine the current system's mainboard vendor and model information:

       1.  If the config file /etc/edac/mainboard exists, then it is parsed by ras-mc-ctl. The mainboard config file has the following simple syn-
	   tax:

		  vendor = <mainboard vendor string>
		  model =  <mainboard model string>
		  script = <script to gather mainboard information>

	   Where  anything  after a '#' character on a line is considered a comment.  If the keyword script is specified, then that script or exe-
	   cutable is run by ras-mc-ctl to gather the mainboard vendor and model information. The script should write the resulting information on
	   stdout in the same format as the mainboard config file.

       2.  If no mainboard config file exists, then ras-mc-ctl will attempt to read DMI information from the sysfs files

		/sys/class/dmi/id/board_vendor
		/sys/class/dmi/id/board_name

       3.  If  the sysfs files above do not exist, then ras-mc-ctl will fall back to parsing output of the dmidecode(8) utility. Use of this util-
	   ity will most often require that ras-mc-ctl be run as root.
