Setting up the Dell DR Series System with IBM Tivoli Storage Manager

3.1.2

Configuring the iSCSI initiator – Linux

Before you begin this procedure, ensure that the iSCSI initiator is installed (iscsi-initiator-utils). For

example, enter the following command:

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.

6.

Run the “cat /proc/scsi/scsi” command to see the LUN and HOST details
