Understanding Port Mode Options
The Fibre Channel ports support Private and Public Fibre Channel attachments. The default port mode
setting is Public Target. You can view the settings and change port parameters.
INITIATOR
In this mode, the port operates as an initiator allowing Fibre Channel targets (disks, tape devices, or FC
switch) to attach to it.
TARGET
In this mode, the port operates as a target allowing a Fibre Channel initiator (host or FC switch) to attach to
it.
TARGET AND INITIATOR
In this mode, the appliance has access to target devices on the Fibre Channel, and initiators on the Fibre
Channel have access to targets attached to the appliance. The port operates simultaneously as a target and
initiator.
PRIVATE
With this option, the appliance scans the local loop for devices but does not check for fabric devices. Select
this option if you are connecting target devices directly to the port.
PUBLIC
With this option, the appliance scans the loop for fabric devices. If it finds a fabric device, it logs on and
queries the name server for target devices that are available on the fabric. If it finds targets attached to the
fabric, it adds all of them to the device map. Select this option if you are connecting a Fibre Channel switch
to the port and you want the appliance to have access to all of the available target devices attached to the
switch. Otherwise, if target devices are connected directly to the port, it automatically switches to Private
mode.
Understanding Connection Type Options
The Fibre Channel ports support both Loop and Point-to-Point connection options. The default connection
setting is Loop.You can view the settings and change port parameters.
LOOP
With this connection option, the port operates with attached loop-capable devices. If a point-to-point device
is attached, the appliance is not able to communicate with it.
POINT-TO-POINT
With this connection option, the port supports point-to-point fabric connection (F_Port Login). It also
operates in “old port mode” for compatibility with N_Port devices that do not support Loop. If loop-capable
devices are attached, the appliance is not able to communicate with them.
LOOP PREFERRED
With this connection option, the port operates in Loop mode unless it detects a connection to an N_Port
device in which case it automatically switches to Point-to-Point.
