Tech Tip: Retrieve Disk Info from the Command Line

 in

You can use the following command line tools to retrieve the make and model of your hard drives without the need to open up your system.

First, you need the device names of your disks, for this you can use df or cat /proc/partitions. Example device names are names such as /dev/hda or /dev/sdb. For the following examples, where applicable, I will use /dev/sda as my disk device.

Use the lshw command:

$ lshw -class disk
...
-disk:0
       product: ST3250310NS
       vendor:  Seagate
       version: SN04
       serial:  9SF0000TH
       size:    232GiB (250GB)

Use the smartctl command:

$ smartctl -i /dev/sda
...
Device Model:     ST3250310NS
Serial Number:    9SF0000TH
Firmware Version: SN04
...

Note: You may need to install the 'smartmontools' package, your output will vary depending on smartctl version and disk make/model.

Use the hdparm command:

$ hdparm -i /dev/sda

/dev/sda:

 Model=ST3250310NS, FwRev=SN04, SerialNo=9SF0000TH
...

Use the hwinfo command:

$ hwinfo --disk
...
Model:     "ST3250310NS"
Device:    "ST3250310NS"
Revision:  "SN04"
Serial ID: "9SF0000TH"
...

Note: You may need to install the 'hwinfo' package.

Note, you will need to be root to get the full output from these commands.

And one additional way that you can determine the model and serial number of your disk:

$ ls /dev/disk/by-id

ata-ST3250310NS_9SF0000TH
ata-ST3250310NS_9SF0000TH-part1
ata-ST3250310NS_9SF0000TH-part2
ata-ST3250310NS_9SF0000TH-part3

Here the model number is ST3250310NS, and the serial number is 9SF0000TH.

here's a "one-liner" that makes use of standard utils (find, grep, etc.) when the above commands aren't available or are lacking:


for file in $(find /sys/block/[sh][dr]*/device/ /sys/block/[sh][dr]*/ -maxdepth 1 2>/dev/null|egrep '(vendor|model|/size|/sys/block/[sh][dr]./$)'|sort); do [ -d $file ] && echo -e "\n -- DEVICE $(basename $file) --" && continue; grep -H . $file|sed -e 's|^/sys/block/||;s|/d*e*v*i*c*e*/*\(.*\):| \1 |'|awk '{if($2 == "size") {printf "%-3s %-6s: %d MB\n", $1,$2,(($3 * 512)/1048576)} else {printf "%-3s %-6s: ", $1,$2;for(i=3;i<NF;++i) printf "%s ",$i;print $(NF) };}';done

For better viewing:

for file in \
        $(find /sys/block/[sh][dr]*/device/ /sys/block/[sh][dr]*/ -maxdepth 1 2>/dev/null | \
              egrep '(vendor|model|/size|/sys/block/[sh][dr]./$)'|sort)
do
    [ -d $file ] && \
        echo -e "\n -- DEVICE $(basename $file) --" && \
        continue

    grep -H . $file | \
        sed -e 's|^/sys/block/||;s|/d*e*v*i*c*e*/*\(.*\):| \1 |' | \
        awk ' {
                  if ( $2 == "size" ) {
                      printf "%-3s %-6s: %d MB\n", $1,$2,(($3 * 512)/1048576)
                  }
                  else {
                      printf "%-3s %-6s: ", $1,$2
                      for ( i=3; i

p.s. A "one liner"...? Don't be afraid of the guys in the white coats, they're here to help.

One Click, Universal Protection: Implementing Centralized Security Policies on Linux Systems

As Linux continues to play an ever increasing role in corporate data centers and institutions, ensuring the integrity and protection of these systems must be a priority. With 60% of the world's websites and an increasing share of organization's mission-critical workloads running on Linux, failing to stop malware and other advanced threats on Linux can increasingly impact an organization's reputation and bottom line.

Linux Backup and Recovery Webinar

Most companies incorporate backup procedures for critical data, which can be restored quickly if a loss occurs. However, fewer companies are prepared for catastrophic system failures, in which they lose all data, the entire operating system, applications, settings, patches and more, reducing their system(s) to “bare metal.” After all, before data can be restored to a system, there must be a system to restore it to.

In this one hour webinar, learn how to enhance your existing backup strategies for better disaster recovery preparedness using Storix System Backup Administrator (SBAdmin), a highly flexible bare-metal recovery solution for UNIX and Linux systems.
