If a VDS iSCSI hardware provider for the storage array is installed on the SFW server, then expanding the iSCSI array node displays the Microsoft iSCSI Software Target subsystem that contains the LUNs and physical disks that make up your iSCSI SAN. The LUNs in a subsystem can be one of the following types shown in the following table.

Table: Description of LUNs

Icon	Name	Description
	LUN	LUN contained in the subsystem and assigned to this iSCSI initiator.
	Foreign LUN	LUN contained in the subsystem and assigned to another iSCSI initiator.
	Idle LUN	LUN contained in the subsystem, but not assigned to any iSCSI initiator.

Selecting a subsystem displays the tabs that let you view lists of the targets, LUNs, or drives in the right pane.

You can view additional information as follows:

Double-clicking an entry in the list of targets displays the tabs that let you view the sessions and the portal groups of the target.
Double-clicking an entry in the list of LUNs displays the tabs that let you view the paths that connect to the physical disk, details of the physical disk, and the targets that the LUN supports.
Double-clicking an entry in the list of drives displays its details.

Selecting a LUN under the subsystem node displays the tabs that let you view the paths that connect to the physical disk, details of the physical disk where the LUN is located on the target server, and targets.

Expanding a LUN in the tree-view that is assigned to the iSCSI initiator, displays the physical disk for the LUN. Selecting the physical disk displays details of the physical disk in the right pane.

To support an SFW Dynamic Multi-Pathing (DMP DSMs) environment, the MPIO option of the Microsoft iSCSI Initiator and the appropriate DSM for the iSCSI target need to be installed. (SFW provides the VITARGET DSM to support Microsoft iSCSI Target.)

In an SFW Dynamic Multi-Pathing environment, selecting a physical disk under the subsystem node displays the tabs that let you view the volumes, disk regions, disk views, and alerts associated with the physical disk.

The following functions to manage the targets are available in a context menu for each LUN node:

Assign To Target
Unassign Target
Properties

Details for these functions are as follows:

Assign To Target	To assign a LUN to a target, right-click the LUN node (under the tree view of the target, under the tree view of the array, or under the LUNs tab when selecting an array), select Assign To Target to launch the Assign LUN To Target Wizard. The wizard lets you select from a list of available targets.
Unassign Target	To unassign a LUN from a target, right-click the LUN node (under the tree view of the target, under the tree view of the array, or under the LUNs tab when selecting an array), select Unassign Target to launch the Unassign LUN From Target Wizard. The wizard lets you select from a list of assigned targets.
