• Connection - This option sets the type of connection that is being used from the host or switch. Use
the Automatic setting for most environments where it will attempt to use Loop Only first then Point
to Point. For custom settings, if you are connecting to a FL_Port switch or NL_Port HBA then select
Loop Only, and if you are connecting F_Port switch or N_Port HBA then select Point to Point.
9.2.3.2 F5402E/F5412E RAID Controller Systems
In the Host Ports section, you can change the LUN (ID) assigned to each of the controller ports, set the
type of connection, and set the data rate.
• Controller Port ID (P0 = Host 0) - This is the target ID for both controller(s) port 0. It can range from:
Soft Address, or 0 - 125. The default is ID 4.
• Controller Port ID (P1 = Host 1) - This is the target ID for both controller(s) port 1. It can range from:
Soft address, or 0 - 125. The default is ID 5.
Note: The ports are identified in the software as P0 and P1, they refer to the label on the RAID
Controller which indicates Host 0 and Host 1 connectors respectively. Controller 0 refers to
the lower controller and Controller 1 is the upper controller.
• Controller Port Data Rate - Use the Automatic setting for most configurations. If you choose to use
a specific setting (1 Gb, 2 Gb, or 4 Gb) you override the automatic setting. Be sure the software
setting here matches the hardware switch setting on the HBA ports.
Note: When using an Active-Active configuration (dual controllers) set the Controller Port Data
Rate to a predetermined speed. When the Automatic setting is used with Active-Active it is
possible for the speed to step down to 1Gb during a fail-back operation. For 2 Gb or 4 Gb
operations, manually setting the speed will prevent this from happening.
