ATTO Technology Inc. iPBridge Installation and Operation Manual
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 CAUTION
Changing the device map can affect the
host’s view of devices and your application
configuration.
To map SCSI devices, you must connect the devices
to the iPBridge SCSI port. To access mapped SCSI
devices over iSCSI, you must have a host computer
connected to the iPBridge iSCSI 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.
• 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.
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 25 for information
about ExpressNAV.
Automatically configure a single target
1 If you have not already, open an ExpressNAV
session. For instructions, refer to

ExpressNAV session on page 25 , click Enter
Here, type in your user name and password,
and click OK.
2 The Status page appears. From the
ExpressNAV menu, select Auto Target Mgt.
3 Click on the Map all devices to default target
button.
4 When the action is complete, the iSCSI Target
Management page appears. Make any
adjustments to the mapping or begin a
discovery session.
5 When 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

ExpressNAV session on page 25 , click Enter
Here, type in your user name and password,
and click OK.
2 The Status page appears. Select the Manual
Target Mgt menu item on the left panel.
3 Click on the Device Maps link of the default
target.
4 Select the devices from the box on the right
panel and drag to the appropriate LUN on the
central panel.
5 Click Submit.
If you are prompted to restart the iPBridge, go
to the Firmware Restart page and restart the
iPBridge.
Multiple target nodes
Multiple targets allow you to create a more
configurable mapping scheme which can segregate
