About Linux Open-iSCSI Initiator

The Linux Open-iSCSI Initiator is a built-in package in Ubuntu 8.04 LTS or later. You

can connect to an iSCSI volume at a shell prompt with a few commands. For more

information about Ubuntu, see:

Before you start

Install the Open-iSCSI package. The package is also known as the Linux Open-

iSCSI Initiator.

To install the Open-iSCSI package, type the following command:

# sudo apt-get install open-iscsi

To connect to an iSCSI target (NAS) with Linux Open-iSCSI Initiator:

STEP 1 You might need to modify the iscsid.conf for CHAP logon information, such as

node.session.auth.username and node.session.auth.password. Type the following

command:

# vi /etc/iscsi/iscsid.conf

STEP 2 Save and close the file. Then restart the open-iscsi service using the following

command:

# /etc/init.d/open-iscsi restart

STEP 3 Discover the iSCSI targets on a specific host (the NAS in this example). For

example, IP address is 10.8.12.31 and a default port number 3260.

# iscsiadm -m discovery -t sendtargets -p 10.8.12.31:3260

STEP 4 Check the available iSCSI node(s) to connect.

# iscsiadm -m node

You can delete the node(s) you don’t want to connect to when the service is on

with the following command:

# iscsiadm -m node --op delete --targetname THE_TARGET_IQN

STEP 5 Restart open-iscsi to login to all the available nodes.

# /etc/init.d/open-iscsi restart
