NDMP backup port settings

OneFS assigns default settings to each Fibre Channel port on the Backup Accelerator node attached to the Isilon 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:

Setting
Description
LNN
Specifies the logical node number of the Backup Accelerator node.
Port
Specifies the name and port number of the Backup Accelerator 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 Fibre Channel switch directly connected to the port.
Loop
Multiple backup devices 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 world wide node name (WWNN) of the port. This name is the same for each port on a given node.
WWPN
Specifies the world wide 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.
State
Specifies whether a port is enabled or disabled.
Actions
Allows you to view and edit the port settings.
