Query iSCSI ID of a device node on Linux?

  • 772

I have some iSCSI targets mounted on a linux host as /dev/sd*. How can I query the iSCSI ID from the device node?

This is on CentOS 5, using the iscsi-initiator-utils package.

linux iscsi

    If you look into 

     /dev/disk/by-path/

    you should see links to your devices

  2. iscsiadm --mode session -P 3

    That will produce lots of extraneous output. You care about the Target line that comes before the Attached scsi disk line for the device in question.

  3. I'm pretty sure you can get the ID by issuing iscsiadm -m discovery -t st -p <target-ip>.
