Interpreting Hardware Paths The following illustration is the Fibre Channel hardware path format: Figure 1-2 Example of a Hardware Path for a Public Loop Device Adapter Domain Area Port Bus Target LUN 0/1/2/0.1.19.255.15.4.0 Figure 1-3 Example of a Hardware Path for a Direct Fabric Attach Device Adapter Domain Area Port Bus Target LUN 0/1/2/0.1.19.255.0.0.0 Figure 1-4 Example of a Hardware Path for a Private Loop Device Adapter Domain Area Port Bus Target LUN 0/1/2/0.8.0.255.0.1.0 Each field in the hardware path is described below: Field Value Information Fibre Channel Topology of HBA Fabric Topologies such as Public Loop and Direct Fabric Attach Private Loop Adapter This is the hardware path of the Fibre Channel adapter through which the LUN is seen. In the case of multi-port adapters, this field describes a specific port on the adapter. Chapter 1 13
