NAME

       edac-ctl - EDAC admin utility

SYNOPSIS

       edac-ctl [OPTION]...

DESCRIPTION

       The  edac-ctl  program is a perl(1) script which performs some useful administration tasks
       for 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  edac-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).

       --register-labels
              Register motherboard DIMM labels into EDAC driver sysfs files.   This  option  uses
              the  detected mainboard manufacturer and model number in combination with a "labels
              database" found in any of the files under /etc/edac/labels.d/* or in the  labels.db
              file  at  /etc/edac/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.

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

MAINBOARD CONFIGURATION

       The  edac-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  edac-ctl.  The
           mainboard config file has the following simple syntax:

                  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 executable  is  run  by  edac-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 edac-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 edac-ctl will fall back to parsing output
           of the dmidecode(8) utility. Use of this utility will most often require that edac-ctl
           be run as root.
