Connecting Remote iSCSI Devices to Storage Cluster Nodes
--------------------------------------------------------

|product_name| allows you to connect remote iSCSI devices to nodes and perceives their LUNs as storage disks. You can connect iSCSI devices to nodes at any time.

To connect a remote iSCSI device to a node, do the following:

#. On the **NODES** screen, select a node, open its **DISKS** tab, and click **iSCSI target**.

   .. image:: /images/stor_image1_14_1.png
      :align: center
      :class: align-center

#. In the **Remote iSCSI Target** window, do the following:

   #. Specify the IQN of the target.

   #. In the **Portal** and **Port** fields, specify the target's IP address and port (optional) and click the corresponding check icon.

   #. (Optional) If the target has multiple paths, click **Add portal** and configure it as in the previous step.

   #. (Optional) If necessary, check **CHAP authentication** and specify the credentials.

   #. Click **Connect**.

|product_name| will connect the target (i.e. all its LUNs) and initiate it; corresponding entries with the **iSCSI** type will appear in the node's **DISKS** list.

To remove the iSCSI target, click **iSCSI Target**, **DELETE CONNECTION**, and **DELETE**.

.. _Assigning Disk Roles To Remote iSCSI Devices:

Assigning Disk Roles To Remote iSCSI Devices
~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~

If the node had already been in the cluster before you connected the iSCSI device to it, assign disk roles to all its LUNs. To do this:

#. Select a disk with the **iSCSI** type and click **Assign**.

#. In the **Choose role** window, select **Storage** and click **Done**.

#. Repeat the above steps for every disk with the **iSCSI** type.

.. note:: You can assign metadata or cache roles to these disks but it is recommended only for single-node installations with SAN-provided redundancy that host Acronis Backup Gateways. For more information on disk roles, see the roles description in :ref:`Assigning Disk Roles Manually`.
