Target Management; Target Names; Default Target Node - ATTO Technology iPBridge 2600 Installation And Operation Manual

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 devices, you must connect the devices to
one of the iPBridge SCSI ports. To access mapped
devices over Ethernet, you must have a host
computer connected to one of the iPBridge
Ethernet data ports.
You have two options to map devices:
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.

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. The iPBridge maps devices
automatically although you can map devices
yourself.
Automatically configure a single target
1 If you are not already in the ExpressNAV GUI,
type the IP address of your iPBridge, as found
in Discover the IP address
standard browser and press Enter.
2 From the ExpressNAV main menu, click on the
Auto Target Mgt menu item on the left side of
the screen.
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.

If you divide the default single target node into
multiple target nodes, you must set up access to
each node separately.
See Exhibit 2.1-1 on page 9 to see the difference
between single target node and multiple target
nodes.

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