Configuring

Channel Speed
Each FC Channel can be configured as 1 Gbps/sec, 2 Gbps/sec, 4 Gbps/sec or
use “Auto” option for auto speed negotiation between 1G/4G. The controller de-
fault is “Auto”, which should be adequate under most conditions. The Channel
Speed setting takes effect for the next connection. That means a link down or bus
reset should be applied for the change to take effect. The current connection
speed is shown at end of the row. You have to click the “Fibre Channel Config”
link again from the Menu Frame to refresh display of current speed.
Channel Topology
Each FC Channel can be configured as Fabric, Point-to-Point, Loop or Auto
Topology. The controller default is “Auto” topology, which takes precedence of
Loop topology. Firmware restart is needed for any topology change to take effect.
The current connection topology is shown at end of the row. You have to click the
“Fibre Channel Config” link again from the Menu Frame to refresh display of
current topology. Note that current topology is shown as “None” when no suc-
cessful connection is made for the channel.
Hard Loop ID
This setting is effective only under Loop topology. When enabled, you can manu-
ally set the Loop ID in the range from 0 to 125. Make sure this hard assigned ID is
not conflicted with any other devices on the same loop; otherwise the channel will
be disabled. It is a good practical to disable the hard loop ID and let the loop itself
auto arrange the Loop ID.
3.9.2.1 View/Edit Host Name List
To set up LUN masking for each volume, a host list should be established at first.
This is done by clicking “View/Edit Host Name List” link at bottom of “Fibre Chan-
nel Config” page (refer to section 3.9.2). Only hosts that will be used as include/
exclude filters are necessary to be added.
The subsystem provides two way to add a host to the list:
