Linux – find information about hardware
Posted: November 19th, 2012 | Author: karol | Filed under: Linux | Comments Off on Linux – find information about hardware
Download this page in PDF formatLinux provides a great variety of tools to provide a wealth of information about hardware on which it is running.
dmidecode
Dmidecode is probably my favorite tool. It provides not only description of hardware but also other useful information such as serial numbers and BIOS version. To illustrate power of dmidecode, I was asked whether memory can be upgraded on one of our Dell servers. This includes finding out how many memory slots are available and how many are occupied at the present. All of this information can be obtained at once with dmidecode:
dmidecode -t memory | grep Size
Size: 16384 MB Size: 16384 MB Size: 16384 MB Size: 16384 MB Size: No Module Installed Size: No Module Installed Size: No Module Installed Size: No Module Installed Size: 16384 MB Size: 16384 MB Size: 16384 MB Size: 16384 MB Size: No Module Installed Size: No Module Installed Size: No Module Installed Size: No Module Installed
As the above shows, there are 16 memory slots on the server, with 8 of them holding 16GB DIMMs, and 8 being empty and available for upgrades.
Another frequent use of dmidecode is to find the server model and its serial number:
dmidecode -t system

Information about BIOS can be obtained with:
dmidecode -t bios

dmesg
Dmesg is used to display bootup messages. These messages contain a lot of details about hardware. For instance to quickly learn about NICs hardware, one could use:
dmesg | grep eth

Quick, albeit not detailed, info about installed disks can be displayed with:
dmesg | grep -i disk

If you require more detailed information about PCI devices, run lspci with -v option, or even with -vv.
smartctl
Probably the best tool to learn about installed hard drives is smartctl. Smartctl communicates with SMART system on a hard drive firmware – practically all hard drives on the market these days support SMART. Most useful information that smartctl can provide is the disk model and its serial number.
Using smartctl is straightforward with disks that are not behind hardware RAID controllers, such as in this example:
smartctl -a /dev/sda
smartctl 5.42 2011-10-20 r3458 [x86_64-linux-2.6.43.8-1.fc15.x86_64] (local build) Copyright (C) 2002-11 by Bruce Allen, http://smartmontools.sourceforge.net === START OF INFORMATION SECTION === Model Family: Seagate Momentus 7200.4 Device Model: ST9320423AS Serial Number: 5VJ8MAKR LU WWN Device Id: 5 000c50 02af0f454 Firmware Version: D005SDM1 User Capacity: 320,072,933,376 bytes [320 GB] Sector Size: 512 bytes logical/physical Device is: In smartctl database [for details use: -P show] ATA Version is: 8 ATA Standard is: ATA-8-ACS revision 4 Local Time is: Mon Nov 26 21:34:45 2012 EST SMART support is: Available - device has SMART capability. SMART support is: Enabled
Situation gets more complicated when trying to use smartctl to communicate with disks that are connected to RAID controllers. First, some of controllers are not supported by smartmontools (smartctl command is part of smartmontools) in which case smartctl cannot be used to query disks. One can check supported controllers on the smartmontools website http://sourceforge.net/apps/trac/smartmontools/wiki. If the RAID controller is supported, the following example illustrates how to query disks on such controller. This example is for LSI Mega Raid family of controllers such as Dell’s Perc controllers. “megaraid,12” means that we are querying disk number 13 on the controller (numbering starts at 0). The device name – /dev/sda in this example – does not really matter but it must be provided and it must exist. The same output would be obtained in our example when /dev/sda is substituted by /dev/sdb.
smartctl -a -d megaraid,12 /dev/sda

lsscsi
lsscsi is a great tool to learn about SCSI devices present on the system. Since scsi driver is used to communicate also with SATA, and SAS devices, lsscsi displays info about practically all hard drives, logical volumes, CD/DVD drives, etc.
lsscsi -g

udevadm
Udevadm is a more “exotic” command – one of not widely known and rarely used commands. It is udev management tool, but it can also be applied to obtain useful information on disks:
udevadm info --query=all --name=/dev/sda
P: /devices/pci0000:00/0000:00:04.0/0000:03:00.0/0000:04:00.0/0000:05:00.0/host4/target4:2:0/4:2:0:0/block/sda N: sda S: block/8:0 S: disk/by-id/scsi-36782bcb047a1840016cd284b05e47524 S: disk/by-path/pci-0000:05:00.0-scsi-0:2:0:0 S: disk/by-id/wwn-0x6782bcb047a1840016cd284b05e47524 E: UDEV_LOG=3 E: DEVPATH=/devices/pci0000:00/0000:00:04.0/0000:03:00.0/0000:04:00.0/0000:05:00.0/host4/target4:2:0/4:2:0:0/block/sda E: SUBSYSTEM=block E: DEVNAME=sda E: ID_SCSI=1 E: ID_VENDOR=DELL E: ID_VENDOR_ENC=DELL E: ID_MODEL=PERC_H700 E: ID_MODEL_ENC=PERC\x20H700 E: ID_REVISION=2.10 E: ID_TYPE=disk E: ID_SERIAL=36782bcb047a1840016cd284b05e47524 E: ID_SERIAL_SHORT=6782bcb047a1840016cd284b05e47524 E: ID_WWN=0x6782bcb047a18400 E: ID_WWN_VENDOR_EXTENSION=0x16cd284b05e47524 E: ID_WWN_WITH_EXTENSION=0x6782bcb047a1840016cd284b05e47524 E: ID_SCSI_SERIAL=002475e4054b28cd160084a147b0bc82 E: ID_BUS=scsi E: ID_PATH=pci-0000:05:00.0-scsi-0:2:0:0 E: ID_PART_TABLE_TYPE=dos E: MAJOR=8 E: MINOR=0 E: DEVTYPE=disk E: DEVLINKS=/dev/block/8:0 /dev/disk/by-id/scsi-36782bcb047a1840016cd284b05e47524 /dev/disk/by-path/pci-0000:05:00.0-scsi-0:2:0:0 /dev/disk/by-id/wwn-0x6782bcb047a1840016cd284b05e47524
The above shows that /dev/sda is a block device attached to Dell Perc H700 controller. It contains DOS type partition table.
udevadm info --query=all --name=/dev/sdg

The above indicates that /dev/sdg is a Seagate USB disk with GPT partition table.
/proc
/proc pseudo-filesystem can also provide some details of hardware configuration. Probably most commonly used are /proc/meminfo, and especially /proc/cpuinfo which is a basic tool to learn about installed processor(s):

lshw
Most Linux distros, and certainly Debian and Red Hat type distros, provide a convenient tool – lshw – to collect and list hardware configuration. Lshw’s output can be quite lengthy. Try “lshw -short” to start. You can also list just a particular class of hardware such as “-class memory” which will also show information on processor caches and installed BIOS:
