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 logical unit numbers (LUNs) that are assigned to a target must start a separate logon session with that target.


This feature enables you to perform a select subset of the tasks that relate to iSCSI configuration and administration. You can also perform these and other tasks using the Microsoft iSCSI Initiator, which is included in Windows Server 2008 in Administrative Tools. Additionally, vendors of networking and storage solutions provide similar tools to perform iSCSI configuration and administration tasks. For more information about iSCSI, see


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 Manage iSCSI 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 interface, if available (this depends on the iSCSI initiator software that is installed on that server).

Membership in the local Administrators group, or equivalent, is the minimum required to complete this procedure. Review details about using the appropriate accounts and group memberships at

To log on to 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. In the Actions pane, click Refresh, and then follow these instructions from step 2.

  4. In the Log On to Target dialog box, select the type of Challenge Handshake Authentication Protocol (CHAP) authentication to use for the logon session:
