What is the meaning of `SCSI3 (0,0,0)` in Partition disks during Ubuntu installation?

  • 772

I observed the following message during Ubuntu installation. What is the meaning of SCSI3 (0,0,0) in Partition disks during Ubuntu installation?

I assume SCSI3 is the Small Computer System Interface 3 based on information from https://www.techopedia.com/definition/17302/scsi-3

Small Computer System Interface 3 (SCSI-3) is an ongoing standardization effort for extending the features of SCSI-2.

What about (0,0,0)? Any idea what are these numbers for?

I've attached the screenshot for your reference.

  1. It means:

    • Controller 0
    • Disk 0
    • Partition 0

    So it is the 1st disk controller, the 1st disk and the 1st partition on that disk.

    ls -1d /sys/class/scsi_device/*/device/block/*

    will list them all and also show the device name used for it.Example:

    $ ls -1d /sys/class/scsi_device/*/device/block/*
/sys/class/scsi_device/2:0:0:0/device/block/sr0
/sys/class/scsi_device/4:0:0:0/device/block/sda
/sys/class/scsi_device/5:0:0:0/device/block/sdb
