3.1.3 Configuring the iSCSI target – Linux
Before you begin this procedure, ensure that the iSCSI initiator is installed (iscsi-initiator-
utils). For example:
yum install iscsi-initiator-utils ; /etc/init.d/iscsi start
To configure the iSCSI target for Linux, follow these steps.
1. Add the CHAP Authentication details for the DR Series system on the Linux Initiator
as follows:
a. Edit /etc/iscsi/iscsid.conf and un-comment the following line:
node.session.auth.authmethod = CHAP
b. Modify the following lines:
# To set a CHAP username and password for initiator
# authentication by the target(s), uncomment the following
lines:
node.session.auth.username = iscsi_user
node.session.auth.password = St0r@ge!iscsi
2. Set the Discovery Target Node(s) by using this command:
iscsiadm -m discovery -t st -p <IP or IQN of DR>
For example:
iscsiadm -m discovery -t st -p 10.8.230.108
3. Enable logon to the DR Series system iSCSI VTL target(s) by using the following
command:
iscsiadm -m node --portal <IP or IQN of DR:PORT> --login
For example:
iscsiadm -m node --portal "10.8.230.108:3260" --login
4. Display the open session(s) with DR VTL(s) by using the following command:
iscsiadm -m session
For example:
iscsiadm -m session = tcp: [8] 10.8.230.108:3260,1 iqn.1984-
05.com.dell:dr4000.3071067.interoprhel52n1.30
5. Review dmesg or /var/log/messages for details about the tape devices created
upon adding the DR Series system iSCSI VTL.
