Linux lsscsi: See List Of All SCSI / SATA Hard Disks and CD / DVD Drives

by

The lsscsi command can be used to list all SCSI / SATA hard disks and CD / DVD drives on a Linux system. Here’s how to use it:

  1. Open a terminal on your Linux system.
  2. Type the following command and press Enter:
    lsscsi

    This will display a list of all SCSI / SATA devices on your system, including hard disks and CD / DVD drives.

    The output will be in the following format:

    [HOST]:[CHANNEL]:[ID]:[LUN] [TYPE] [VENDOR]:[MODEL] [REVISION]

    Here’s what each field means:

    • HOST: The SCSI host number.
    • CHANNEL: The SCSI channel number.
    • ID: The SCSI ID of the device.
    • LUN: The Logical Unit Number of the device.
    • TYPE: The device type, such as disk, tape, CD/DVD, or optical.
    • VENDOR: The vendor of the device.
    • MODEL: The model of the device.
    • REVISION: The firmware revision of the device.

    For example, the following output shows two hard disks (sda and sdb) and a CD/DVD drive (sr0):

    [0:0:0:0] disk ATA WDC WD2500JS-22N 03.0
    [1:0:0:0] disk ATA WDC WD10EZEX-08M 01.0
    [2:0:0:0] cd/dvd TSSTcorp CDDVDW SH-S223C SB03

    The first field ([0:0:0:0], [1:0:0:0], etc.) identifies the device’s location on the SCSI bus. The second field (disk or cd/dvd) indicates the device type, and the third field (ATA or TSSTcorp) is the vendor.

    Note that you need to have SCSI/SATA hardware and the lsscsi utility installed to use this command.
