Configuring an iSCSI client

First update your package list by running:

sudo apt update

Next up is to install open-iscsi.

sudo apt install open-iscsi

Now that it is installed you will have to enable the service for it. Don't yet start it.

sudo systemctl enable iscsid

Time to configure iSCSI, first open the file "/etc/iscsi/initiatorname.iscsi". And set the Initiator Target to the correct value.

InitiatorName=iqn.2005-10.be.iswleuven.nas1

Time to open the iSCSI configuration file. Comment the manual version and uncomment the automatic line.

# To request that the iscsi initd scripts startup a session set to "automatic".
node.startup = automatic
#
# To manually startup the session set to "manual". The default is manual.
#node.startup = manual

Also if you have a CHAP username and password set configure it using "node.session.auth.username" and "node.session.auth.password".

Once that is done you can run the following:

sudo iscsiadm -m discovery -t sendtargets -p <iSCSI_SERVER_IP>

This command will list all the available targets you can use. To actually login to a target you can write:

sudo iscsiadm -m node -p <iSCSI_SERVER_IP> -T <TARGET> --login
# For example:
sudo iscsiadm -m node -p 172.20.250.1 -T iqn.2005-10.be.iswleuven.nas1:gluster02 --login
