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.
