edac-ctl - EDAC admin utility
The edac-ctl program is a perl(1) script which performs some useful administration tasks for EDAC (Error Detection and Correction) drivers.
- Display a brief usage message.
- 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.
- Print the status of EDAC drivers (loaded or unloaded).
- 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.
- Display the configured labels for the current hardware, as well as the current labels registered with EDAC.
- Specify an alternate location for the labels database.
The edac-ctl script uses the following method to determine the current system's mainboard vendor and model information:
- If the config file /etc/edac/mainboard exists, then it is parsed by
edac-ctl. The mainboard config file has the following simple
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.
vendor = <mainboard vendor string>
model = <mainboard model string>
script = <script to gather mainboard information>
- If no mainboard config file exists, then edac-ctl will attempt to
read DMI information from the sysfs files
- 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.
