Task 4: (iSCSI Only) Establish Logon Sessions Between the Initiator and Targets

Applies To: Windows Server 2008

For a server to access logical unit numbers (LUNs) that are assigned to a target on an Internet SCSI (iSCSI) subsystem, the server initiator must first establish a session with the target through an iSCSI logon process.

You can log on to iSCSI targets using Storage Manager for SANs. This starts a logon session only between the server that is running Storage Manager for SANs and the selected target. Each server that requires access to the LUNs that are assigned to a target must start a separate logon session with that target.


If you have not yet configured iSCSI security for initiators and targets, you will not be able to log on to a target. For more information about iSCSI security, see Task 3: (iSCSI Only) Configure Security.


You can also start a logon session between a server in your storage area network (SAN) and a target, using the local iSCSI initiator user interface, if available (this depends on the iSCSI initiator software that is installed on that server).

When you log on to a target, you can select the type of Challenge Handshake Authentication Protocol (CHAP) authentication to use during the session. If you have set an IPsec key for the portals, data encryption is automatic.

To establish logon sessions between the initiator and iSCSI targets

  1. In the console tree, click LUN Management.

  2. In the Actions pane, click Log On to iSCSI Targets.

  3. In the Log On to iSCSI Targets dialog box, select the target that you want to establish a logon session with, and click Log On.


If the target that you want to log on to is not listed, click Close. Then, in the Actions pane, click Refresh, and when the refresh has completed, start over from step 2.

  1. In the Log On to Target dialog box, select the type of CHAP authentication to use for the logon session:

    • Log on using one-way CHAP authentication

    • Log on using mutual CHAP authentication

  2. To establish the logon session, click OK.
