How To Configure iSCSI Initiator on SLES
This document (7001308) is provided subject to the disclaimer at the end of this document.
SUSE Linux Enterprise Server 9 Service Pack 4
Configuring the initiator through YaST is a breeze.
First, configure the initiator service to start automatically upon boot by checking the radio box, When Booting.
Next, unless you need to give the initiator a specific name because of infrastructure or corporate policy, click on the Discovered Targets tab. Click on the [Discovery] button, and enter the iSCSI target host's IP address. After clicking [Next], you should see the iSCSI target under the target(s) name(s). Select the desired target, and click on the [Log In] button. For our example, no authentication will be configured, so simply click on [Next]. Now, on the Discovered Targets tab, you should see that this particular target is connected by the [True] in the Connected column.
Finally, click on the Connected Targets tab, and change the start-up mode from Manual to Automatic by clicking on the [Toggle Start-Up] button.
After clicking [Finish], a new device should be detected and ready for use by other services. A good, quick check to verify it's availability is to run 'cat /proc/partitions'.
On SLES9SP4, the linux-iscsi package must first be installed. Again, once installed, time must be in sync. It is suggested that NTP be configured on the iscsi initiators as well as the iscsi target host.
Modify /etc/iscsi.conf. On SLES9, this file is used solely for the initiator configuration. There are many great examples in this file, such as: authentication configuration, CRC digest checking, subnet-specific settings, etc.,. For our example, neither authentication nor CRC digest checking will be configured, so the only addition that need be made is:
The service can then be started manually by entering '/etc/init.d/iscsi start' and should be configured to start automatically upon boot by entering 'chkconfig iscsi on'. Once properly configured and started, a new device should be detected and ready for use by other services. Again a good, quick check to verify it's availability is to run 'fdisk -l'.
