ONFIGURATION

Connecting iSCSI Targets with CHAP for Linux

The following instructions describe how to connect iSCSI targets with CHAP 
authentication using Linux Open-iSCSI Initiator. Open-iSCSI Initiator is available for 
Redhat Enterprise Linux, CentOS, Fedora Linux, Debian, and Ubuntu operating 
systems. For more information about using Open-iSCSI with your specific Linux 
operating system, refer to your Linux distribution web site.

1.

Install Open-iSCSI initiator.

To install the iSCSI initiator, enter the following command:

# yum install iscsi-initiator-utils

For Ubuntu and Debian operating systems, enter the following command:

$ sudo apt-get install open-iscsi

2.

Configure CHAP authentication.

a.

Open the 

iscsid.conf

 file using a vi text editor with the following command:

# vi /etc/iscsi/iscsid.conf

b.

Set the authmethod to CHAP by replacing 

None

 with 

CHAP

 so that the following 

line reads:

 "node.session.auth.authmethod = CHAP" 

! 

Important

Before you shut down or restart the RDX QuikStation 4 for 
any reason, Tandberg Data recommends that you disconnect 
all iSCSI targets.
