iSCSI Initiator

BrickStor supports connecting to iSCSI targets served from external NAS and other network-connected storage systems. Any connected iSCSI targets may be used in the same way as local storage to create new storage pools or to expand an existing one.

BrickStor can connect to iSCSI targets served from the following qualified third party systems:

  • HPE Nimble AF40

  • HPE 3Par 8400

Configuring the iSCSI Initiator

Complete the following steps to configure the BrickStor as an iSCSI Initiator:

  1. In the Connections Pane, select the Appliance level.

  2. In the Details Pane, click the System tab.

  3. Click on the iSCSI Initiator button at the bottom right of the Details Pane.

A new tab will be created in the Details Pane labeled iSCSI Initiator. Navigate to this tab to see the following information:

  • The unique iSCSI Qualified Name (IQN) assigned to the BrickStor (i.e. iqn.2010-03.io.racktop:zz00012k)

  • A button to Configure Initiator

  • A button to Add Target

Configuring Initiator authentication

Once the Configure Initiator button is selected, a pop-up window appears where you can add a CHAP name and secret for the target. The Challenge Handshake Authentication Protocol (CHAP) enables authenticated communication between iSCSI initiators and targets. When you use CHAP authentication, you define CHAP user names and passwords on both the Initiator and the storage system that serves the target.

For IQN, the assigned IQN is again presented and is not editable. You can use this for copy/paste when adding your Initiator on the Target side.

For the Initiator’s CHAP Name, you can either use the already assigned IQN by selecting the associated Use IQN button or enter a free-text name.

For the Initiator’s Chap Secret, you can enter a free text string. A minimum of 12 and a maximum of 16 characters are required.

Select Apply to apply the changes.

Connecting to the iSCSI Target

Once the Add Target button is selected, a pop-up window appears where you can add an iSCSI Target to BrickStor. Adding an iSCSI Target will make it available as a block, or disk, device. Such devices can be used to create new storage pools on BrickStore or to expand an existing pool.

For Initiator IQN, the assigned IQN is again presented and is not editable. You can use this for copy/paste when adding your Initiator on the Target side.

For the Target IQN, you can enter the name of the desired iSCSI Target ensuring the name follows one of three formats:

  • iSCSI Qualified Name (IQN) - iqn.yyyy-mm.reverse-domain-name:unique-name

  • World Wide Name (WWN) - wwn.0123456789ABCDEF

  • Enterprise Unique Identifier (EUI) - eui.0123456789ABCDEF

For TPG Tag, a numeric value may be specified which corresponds to a Target Portal Group (TPG) on the Target.

For Target IP Addresses, the IP address(es) of the desired iSCSI Target may be entered.

If enabling a two-way CHAP is desired, you can elect to Enable Chap. Doing so will require you to enter the following for the Target:

  • Mutual CHAP - Target’s Name

  • Mutual CHAP - Target’s Secret

Select Add Target when all required fields are completed to apply the changes.

Once added, the Target name, Target IP, connectivity status, and a representation of the connected volumes will be presented. Should the connectivity to the Target change, volumes that are associated with it will be shown as being offline.

The configuration setting to the Target can be modified, as well as the ability to remove the iSCSI Target altogether, using the associated icons.
