ATTO Technology Inc. iPBridge Installation and Operation Manual
2.1 Target management
SCSI devices are mapped using the designations for the iSCSI LUN. If you must change the default
automatic mapping, 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 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 1500/1550, you
have two options to map devices after you disable
automatic mapping:
1 The default is set up as a single target node in
which a host or initiator views the iPBridge as a
single iSCSI node with all available devices
shown as LUNs on a single iSCSI target.
2 You may set up multiple target nodes which
allow greater flexibility to grant or deny access
between initiators and devices as needed.
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 accessed through the Ethernet
port on an iPBridge is identified by a unique world-
wide iSCSI-qualified name. This format references the
iPBridge serial number and target node name:
iqn.1995-12.com.attotech:ipbridge:
serialnumber <targetname>
Note
Sample mapping pages are illustrated in
Exhibit 2.1-2 and Exhibit 2.1-3. For
explanations of the CLI commands which
control mapping, refer to
Target management
commands on page 53.
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 29 for information
about ExpressNAV. Exhibit 2.1-3 shows the target
management page.
Map devices automatically
1 If you have not already, open an ExpressNAV
session. For instructions, refer to
Opening an
ExpressNAV session

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 29
2 Click on the Manual Target Mgmt menu item
on the left side of the screen.
3 Click on the Device Maps link of the default
target.
4 Select the devices from the box on the right
hand side of the screen and drag to the
appropriate LUN on the left.
5 Click Submit .
If you are prompted to restart the iPBridge, go
to the
Firmware Restart page and restart the
iPBridge.
