Options

A FC port identified in the form of:

--wwnn <string>

Specifies the world-wide node name (WWNN) of the port as a string of 16 hexadecimal numerals.

--wwpn <string>

Specifies the world-wide port name (WWPN) of the port as a string of 16 hexadecimal numerals.

--state {enable | disable}

Specifies whether the port is enabled or disabled.

--topology {auto | loop | ptp | nport}

Specifies the type of Fibre Channel topology that the port expects. Note that QLogic cards do not support nport topology. The following settings are valid:

auto

Causes the port to detect the topology automatically. This is the recommended setting. Specify this setting if you are using a fabric topology.

loop

Causes the port to expect an arbitrated loop topology, with multiple backup devices connected to a single port in a circular formation.

ptp

Causes the port to expect a point-to-point topology, with one backup device or Fibre Channel switch directly connected to the port.

--rate {auto | 1 | 2 | 4 | 8 | 16 | 32}

Specifies the rate that OneFS will attempt to send data through the port. Note that QLogic cards do not support rates above 8. The following rates are valid:

auto

OneFS automatically negotiates with the DMA to determine the rate. This is the recommended setting.

1

Attempts to send data through the port at a speed of 1 Gb per second.

2

Attempts to send data through the port at a speed of 2 Gb per second.

4

Attempts to send data through the port at a speed of 4 Gb per second.

8

Attempts to send data through the port at a speed of 8 Gb per second.

16

Attempts to send data through the port at a speed of 16 Gb per second.

32

Attempts to send data through the port at a speed of 32 Gb per second.
