This page contains a list of commands to query your system properties (mainly hardware and firmware). It requires a working Linux installation (eg. Ubuntu Server or Fedora).

Installed CPU(s)

cat /proc/cpuinfo
# also very informative
lscpu

Example result (excerpt):

cpu:      POWER9, altivec supported
revision: 2.3 (pvr 004e 1203)

Motherboard

cat /proc/cpuinfo

Example result (excerpt):

machine:  PowerNV C1P9S01 REV 1.01
firmware: OPAL
MMU:      Radix

PCI devices

lspci

Example result (excerpt):

0005:02:00.0 VGA compatible controller: ASPEED Technology, Inc. ASPEED Graphics Family (rev 41)

SATA

Show recognized and activated SATA settings:

dmesg | grep -i sata

eg.

[   3.542383] ata1: SATA max UDMA/133 abar m2048@0x60c100000000 port 0x600c100000100 irq 28

System Firmware versions

sudo lsmcode

eg.

Version of System Firmware :
 Product Name    : OpenPOWER Firmware
 Procuct Version : blackbird-v2.3-rc2-65-g1bd4a042-dirty
 Product Extra   : skiboot-c81f9d6
 Product Extra   : hostboot-3beba24
 Product Extra   : linux-v4.19-openpower1-p048916f
 Product Extra   : petittboot-v1.10.3-pdd2d545
 Product Extra   : machine-xml-17e9e84
 Product Extra   : occ-b010273
 Product Extra   : sbe-459a974
 Product Extra   : hcode-81ae5fd


Sensors (CPU and drive temperatures etc.)

See also the building FAQ...

Installation of lm-sensors:

sudo apt install lm-sensors
sudo sensors-detect          # use all default values by pressing enter when asked

Display current sensor values:

sensors

You can also install GUI-based tools then, eg.:

  • psensor
Psensor screen shot


Via ipmitools (that directly queries OpenBMC and includes Fan RPMs):

sudo apt install ipmitool
sudo ipmitool sensor


NVMe drives (mainly SSDs)

For NVMe drivers lm-sensors does not work.

Instead install the package nvme-cli:

sudo apt install nvme-cli

You can then get then the drive temperatur and other "SMART data" for the first NVMe drive via

sudo nvme smart-log /dev/nvme0
