OneFS assigns default settings to each Fibre Channel port on the Fiber Attached Storage node that is attached to the
PowerScale cluster. These settings identify the port and determine how the port interacts with the NDMP backup devices.
The following settings appear in the
Ports table:
Table 1. Backup Port SettingsThe following table describes each setting.
Setting
Description
LNN
Specifies the logical node number of the Fiber Attached Storage node.
Port
Specifies the name and port number of the Fiber Attached Storage node.
Topology
Specifies the type of Fibre Channel topology that is supported by the port. Options are:
Point to Point
A single backup device or Fiber Channel switch that is directly connected to the port.
Loop
Multiple backup devices that are connected to a single port in a circular formation.
Auto
Automatically detects the topology of the connected device. This is the recommended setting and is required for a switched-fabric topology.
WWNN
Specifies the worldwide node name (WWNN) of the port. This name is the same for each port on a given node.
WWPN
Specifies the worldwide port name (WWPN) of the port. This name is unique to the port.
Rate
Specifies the rate at which data is sent through the port. The rate can be set to
1 Gb/s,
2 Gb/s,
4 Gb/s,
8 Gb/s, and
Auto.
8 Gb/s is available for A100 nodes only. If set to
Auto, the Fibre Channel chip negotiates with connected Fibre Channel switch or Fibre Channel devices to determine the rate.
Auto is the recommended setting.
Actions
Allows you to view and edit the port settings.
