1. Select an iSCSI LUN to unmap from an iSCSI target and click "Disable".
2. Click "Unmap" and the LUN will appear on the Un-Mapped iSCSI LUN List. Click "Map"
to map the LUN to another target.
3. Select the target to map the LUN to and click "Apply"
4. The LUN is mapped to the target.
After creating the iSCSI targets and LUN on the NAS, you can use the iSCSI initiator
installed on your computer (Windows PC, Mac, or Linux) to connect to the iSCSI
targets and LUN and use the disk volumes as the virtual drives on your computer.

The NAS supports expanding the capacity of an iSCSI LUN. To do so, follow the steps
below.
1. Locate an iSCSI LUN on the iSCSI target list in "iSCSI" > "Target Management". Click
"Modify".
2. Specify the capacity of the LUN. Note that the LUN capacity can be increased
many times up to the maximum limit but cannot be decreased.
3. Click "Apply" to save the settings.
Note :
An iSCSI LUN must be mapped to an iSCSI target before increasing the capacity.
For the type of LUN allocation, the maximum LUN capacity for thin provisioning is
32TB, while for instant allocation, the maximum LUN capacity is limited by the
available free space on the disk volume.

In the environments that require high performance storage, such as virtualization, users
are recommended to do the following to optimize the iSCSI and NAS hard disks
performance:

: When creating an iSCSI LUN, select "Instant Allocation" to
achieve slightly higher iSCSI performance. However, the benefits of thin provisioning
will be lost.
