Sharing block devices via iSCSI is a common way to make network-attached storage available. An iSCSI LUN is a logical unit of storage. In SoftNAS, the basic storage LUN is a volume that is accessed as a blockdevice. The blockdevice volumes have a mount point in the Linux /dev/zvol filesystem because they are disk block devices.

For example, VMware or Windows connects to the iSCSI server and retrieves a list of available targets. Then, for each target, the list of its published LUNs are available for use.

Creating a Target
Note: You can publish any number of block device volumes via a single iSCSI target. A default iSCSI target is ready for use. However, if you need another, use the Create A Target link to add new targets as needed.
To do so, simply click the Create a Target option in the toolbar. The additional target will be created automatically, without additional steps.
Adding a LUN
You can create one or more volumes assigned as LUNs (iSCSI logical units) for each target. To do this, select the target, and click Add LUN, or double-click the desired target.

Alternative Method - Double click to Add LUN
Instead of selecting the target and clicking Add LUN, you can simply double-click here, as it states. Follow the steps in #3 to finish adding your LUN.
Deleting a LUN/Target
You can now delete LUNs from a target, without deleting the target. An empty target can be deleted separately.
