How do I find out the make, model and serial number for my SCSI or IDE hard disks under CentOS Linux server? How do I get vendor information about my disk storage w/o opening my Intel / AMD server chassis?

You need to use the hdparm command. It provides a command line interface to various hard disk ioctls supported by the stock Linux ATA/IDE/SATA device driver subsystem i.e. get BIOS information from hard disk.


Getting hard disk model and number under Linux

Try command as follows for /dev/sda (SATA). You need to pass -i or -I option which request identification info directly from the drive, which is displayed in a new expanded format:
# hdparm -I /dev/sda
# hdparm -I /dev/sda | grep Serial

OR for IDE /dev/hda
# hdparm -i /dev/hda
# hdparm -I /dev/hda
Sample outputs:

scsi_id command examples

For SCSI attached disk use scsi_id command which queries a SCSI device via the SCSI INQUIRY vital product data (VPD) page 0x80 or 0x83 and uses the resulting data to generate a value that is unique across all SCSI devices that properly support page 0x80 or page 0x83.
# scsi_id -s /block/sda
# scsi_id -a -s /block/sda
# scsi_id -gus /block/sda


  • -s : Generate an id for the sysfs-device
  • -a : Always print information (model, vendor strings) about the device even if it does not support VPD pages.
  • -g : Treat the device as white listed. The -g option must be specified on the command line or in the scsi_id configuration file for scsi_id to gener ate any output
  • -u : Reformat the output : replace all whitespaces by underscores.

sdparm command

The sdparm command can be used to access SCSI modes pages; read VPD pages; send simple SCSI commands. It can provide all information:
# sdparm -a /dev/sda
# sdparm --vendor sea /dev/sda

    Thanks! – In CentOS, the command for SCSI info is, appropriately enough, scsi-info

  • Valter Espindola Oct 1, 2008 @ 20:54

    Debian systems

    ls /dev/disk/by-id

  • reini Jan 15, 2009 @ 16:04

    for suse 9.x 10.x and other linux 2.6.x producing hdparm errors with s-ata disks

    HDIO_GET_IDENTITY failed: Operation not supported

    use sdparm from freshmeat instead:

    sdparm -p sn /dev/sda

    Can this be achieved using C++ or C program?
    please reply….

    This is like devmgmt.msc that is device manager in windows which will show all the required information about the hardware

    also you can try with

    dmesg|grep vol

    Hi Guys,

    Need help here

    How to get serial number of Hard drive in linux on HP blade 460c?


  • chandra Jul 10, 2013 @ 11:01

    i also tried with hdparm but no luck..

  • Ahmed Oct 20, 2013 @ 23:23

    What if i want to get data of an array of disks. I use multiple disks with RAID-5.

  • Raja Jul 31, 2015 @ 5:32

    with hdparm the error is improper ioctl..:(

    it will work with smartctl -a -i -d
