3.1 Target management

Storage devices are mapped using the designations for the iSCSI LUN. The easiest way to map devices is to use the Automatic Target Management feature in the ATTO ExpressNAV interface.

CAUTION

Changing the device map can affect the host’s view of devices and your application configuration.

You may map each device to its own target, breaking the single iSCSI target node into multiple nodes. Multiple target nodes allow flexibility to grant or deny access between initiators and devices.

To map SCSI devices, you must connect the devices to the iPBridge SCSI port. To access mapped SCSI devices over Ethernet, you must have a host computer connected to the iPBridge Ethernet data port.

If you decide to change the automatic mapping set up when you powered up the iPBridge, you have two options to map devices after you disable automatic mapping:

You may map devices manually to the single default node.

If you divide the default single target node into multiple target nodes, you must set up access to each node separately.

Target names

Each iSCSI target node is identified by a unique world-wide iSCSI-qualified name which references the iPBridge serial number and target node name:

iqn.1995-12.com.attotech:ipbridge: serialnumber <targetname>

Default target node

The default target is set as a single target with Access Control (ACL) disabled and CHAP authentication disabled. The default target node cannot be deleted.

Use the ExpressNAV interface to map devices automatically or manually. Refer to Opening an ExpressNAV session on page 23 for information about ExpressNAV.

Automatically configure a single target

1If you have not already, open an ExpressNAV session. For instructions, refer to Opening an

ExpressNAV session on page 23, click Enter

Here, type in your user name and password, and click OK.

2The Status page appears. From the ExpressNAV menu, select Auto Target Mgt.

3Click on the Map all devices to default target button.

4When the action is complete, the iSCSI Target Management page appears. Make any adjustments to the mapping or begin a discovery session.

5When the action is complete, the iSCSI Target Management page appears. From there you may make adjustments to the mapping or begin a discovery session.

If you are prompted to restart the iPBridge, go to the Firmware Restart page and restart the iPBridge.

Map devices manually

1 If you have not already, open an ExpressNAV session. For instructions, refer to Opening an

ExpressNAV session on page 23, click Enter

Here, type in your user name and password, and click OK.

2The Status page appears. Select the Manual Target Mgt menu item on the left panel.

3Click on the Device Maps link of the default target.

4Select the devices from the box on the right panel and drag to the appropriate LUN on the central panel.

5Click Submit.

If you are prompted to restart the iPBridge, go to the Firmware Restart page and restart the iPBridge.
