2. In the Controller Module Host Port Configuration panels, for each port to which an HBA or switch is attached, set the appropriate link speed. An FC port's link speed must match the speed of the FC HBA or switch to which the port is connected. In a dual-controller system, if FC port interconnects are enabled, changing the speed of a port on one controller also changes the speed of the interconnected port on the other controller. 3. Click Update Host Port Configuration. 4. In the Advanced Options panel, configure FC loop ID, port interconnect, and topology settings as required for your configuration: ■ FC Loop ID: (Loop topology configurations only) If you want data hosts to identify a controller using a specific address, click Change FC Loop ID. In the Requested Loop ID for Host Ports panel, select a specific number (from 1 to 125) for each controller, click Save and Continue, and then click OK to restart the controller. During loop initialization the controller will request the specified ID but it might be assigned another ID instead. ■ Port Interconnect Settings: (Direct attach configurations only) If your configuration requires that host port interconnects be enabled, click Change FC Port Interconnect Settings. In the Host Port Configuration panel, set Internal Host Port Interconnect to Interconnected (enabled), and click Save and Continue. This setting affects all FC ports on both controllers. Note - If one or more ports are set to use point-to-point topology, you cannot enable interconnects. ■ Fibre Channel Topology: (Switch attach configurations only) To change the topology used on controller FC ports from Loop to Point to Point, click Change Host Port Topology. In the Controller Module Host Port Configuration panels, select Point to Point for each port, and click Save and Continue. Note - If interconnects are enabled, you cannot use point-to-point topology.

2.
In the Controller Module Host Port Configuration panels, for each port to which an
HBA or switch is attached, set the appropriate link speed.
An FC port’s link speed must match the speed of the FC HBA or switch to which
the port is connected. In a dual-controller system, if FC port interconnects are
enabled, changing the speed of a port on one controller also changes the speed of
the interconnected port on the other controller.
3.
Click Update Host Port Configuration.
4.
In the Advanced Options panel, configure FC loop ID, port interconnect, and
topology settings as required for your configuration:
■
FC Loop ID:
(Loop topology configurations only) If you want data hosts to
identify a controller using a specific address, click Change FC Loop ID. In the
Requested Loop ID for Host Ports panel, select a specific number (from 1 to 125)
for each controller, click Save and Continue, and then click OK to restart the
controller.
During loop initialization the controller will request the specified ID but it might
be assigned another ID instead.
■
Port Interconnect Settings:
(Direct attach configurations only) If your
configuration requires that host port interconnects be enabled, click Change FC
Port Interconnect Settings. In the Host Port Configuration panel, set Internal Host
Port Interconnect to Interconnected (enabled), and click Save and Continue.
This setting affects all FC ports on both controllers.
Note –
If one or more ports are set to use point-to-point topology, you cannot
enable interconnects.
■
Fibre Channel Topology:
(Switch attach configurations only) To change the
topology used on controller FC ports from Loop to Point to Point, click Change
Host Port Topology. In the Controller Module Host Port Configuration panels,
select Point to Point for each port, and click Save and Continue.
Note –
If interconnects are enabled, you cannot use point-to-point topology.
