3.1.3 Logical Unit addressing for FB2400 only
The FibreBridge 2400 may be configured to take advantage of Logical Unit Addressing using the
Command Line ASCII-based interface.
In standard device mapping and formatting, as
described in
Static device addressing
target devices are only visible if you have mapped
them specifically to Fibre Channel ports. You may
use ATTO ExpressNAV to map devices as
described in
Mapping
If you enable Logical Unit Addressing through
the Command Line Interface (refer to
serial port
on page 7), a scan is performed when
power is applied to the system and a list is made
of all devices. All target devices are visible to all
Fibre Channel ports, with each port sharing a
common Fibre Channel node name.

Using the
One advantage to this method is that you can
enable port failover in which a designated Fibre
Channel port is marked as reserve and becomes
active only if another port fails.
To enable Logical Unit Addressing, use the CLI
and, at the Ready prompt, type
set LogicalUnitAddressing enabled
To see the SCSI address mappings, type
RouteDisplay SCSI
You may designate a specific bus, target, LUN.
