ATTO Technology Inc. iPBridge Installation and Operation Manual
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.
CAUTIONCAUTION
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.
1 You 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.
2 You 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.
Targ et na mes
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 2.2-2 and 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 2.2-2
shows the mapping page.
Map devices automatically
1 From the ExpressNAV main menu, click on the
Automatic Target Management menu item on
the left side of the screen.
2 Click on the Map all devices to default target
button.
3 When 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
1 From the ExpressNAV main menu, click on the
Manual Target Mgmt menu item on the left
side of the screen.
2 Click on the Device Maps link of the default
target.
3 Select the devices from the box on the right
hand side of the screen and drag to the
appropriate LUN on the left.
4 Click Submit.
If you are prompted to restart the iPBridge, go
to the Firmware Restart page and restart the
iPBridge.
