Configuration Overview
30 Network Storage Router e1200-160
Fibre Channel Port Configuration
By default, the configuration of the Fibre Channel ports is set to N_Port, forcing
the router to negotiate a fabric only mode.
Note: By default, the Fibre Channel port speed is set to 2 Gb/s. Changes to the Fibre
Channel port speed must be manually set, such as for 1 Gb/s. If set incorrectly and the
router is plugged into a Loop or Fabric, the unit may receive framing errors, which can be
found in the trace logs, and the fiber link light will be off because of the incorrect Fibre
Channel link speed. For more information on manually setting the Fibre Channel port
speed, see Chapter 3, "Fibre Channel Port Configuration."
Fibre Channel Switched Fabric Configuration
When connected to a Fibre Channel switch, the router is identified to the switch as
a unique device by the factory programmed World Wide Name (WWN).
Discovery Mode
This feature makes it easy to discover attached Fibre Channel and SCSI target
devices and automatically map them on the host side for the bus/port in question.
There are two discovery methods available:
■ Manual discovery
■ Auto discovery
Auto Discovery can be set to occur after reboot events (when the router reboots)
or link-up events (for instance, when cables are attached or a hub is rebooted).
Auto Discovery can be disabled by setting the router to Manual Discovery.
For more information on setting the Discovery Mode, see Chapter 3, "Fibre
Channel Port Configuration," when using the Visual Manager User Interface or
Chapter 4, "Fibre Channel Configuration," when using Serial/Telnet.
Host Device Configuration
A host system using a Fibre Channel Host Bus Adapter (HBA) will typically map
devices into the existing device-mapping scheme used by that operating system.
Refer to the HBA manual for the mapping table.
