Target Management; Target Names; Default Target Node; Automatically Configure A Single Target - ATTO Technology iPBridge 2700C 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 Fibre Channel devices, you must connect
the devices to one of the iPBridge Fibre Channel
ports. To access mapped Fibre Channel devices
over Ethernet, you must have a host computer
connected to one of the iPBridge Ethernet data
ports.
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.
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.

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
interface, type the IP address of your iPBridge
in a standard browser as found in
ExpressNAV on page 23, 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.

3.1 Target management

Using
• You may map each device to its own target to
break the single iSCSI target node into multiple
nodes. Multiple target nodes allow greater
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.
See Exhibit 3.1-1 on page 13 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>
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 are prompted to restart the iPBridge, go
to the Firmware Restart page and restart the
iPBridge.

Map devices manually

1 If you are not already in the ExpressNAV
interface, type the IP address of your iPBridge
in a standard browser as found in
ExpressNAV on page 23, 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 side of the
