2.2 Target management

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

To map devices, you must have a host computer connected to the iPBridge Ethernet port. iSCSI target nodes are accessed through the Ethernet port, each identified by its own IP address.

You have two options to map devices.

1You may use the default target node in which a host or initiator will view the iPBridge as a single iSCSI node with all available devices shown as LUNs on a single iSCSI target.

2You may map each device to its own target to break the single iSCSI target node into multiple nodes. Multiple target nodes allow you to grant

or deny access between initiators and devices as needed.

Target names

Each iSCSI target node accessed through the Ethernet port on an iPBridge is identified by its own IP address.

The iPBridge uses the iqn name format, referencing the device serial number, to guarantee that the target name is world-wide unique such as

iqn.1995-12.com.attotech:ipbridge: serialnumber

Note

Sample mapping pages are illustrated in Exhibit 2.2-2and Exhibit 2.2-3.

Default target node

The default target starts with AccessControl disabled and CHAP authentication disabled. It cannot be deleted.

Use the ExpressNAV interface to map devices automatically or manually. Refer to ATTO ExpressNAV interface on page 19 for information about ExpressNAV. Exhibit 2.2-2shows the mapping page.

Map devices automatically

1From the ExpressNAV main menu, click on the Automatic Target Management menu item on the left side of the screen.

2Click on the Map all devices to default target button.

3When the action is complete, the screen will go to the iSCSI Management page. From there you may make adjustments to the mapping.

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

Map devices manually

1From the ExpressNAV main menu, click on the Manual Target Mgmt menu item on the left side of the screen.

2Click on the Device Maps link of the default target.

3Select the devices from the box on the right hand side of the screen and drag to the appropriate LUN on the left.

4Click Submit.

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