Linux – Query iSCSI ID of a device node on Linux

iscsilinux

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.

If you look into

 /dev/disk/by-path/

you should see links to your devices

TwinStrata required my clinet's iqn number. This is located here:

less /etc/iscsi/initiatorname.iscsi

Once the server change was in place, I restarted the client iscsi service and I could see /dev/sda.

Take a look at block cache solutions, like bcache, flashcashe, l2arc on zfs...
