Interpreting Hardware Paths

3.HP Fibre Channel Mass Storage installation is verified if the ioscan output lists all mass storage devices attached to the adapter. If any attached devices are not listed or appear as UNCLAIMED, see the Troubleshooting and Maintenance chapter of the HP Fibre Channel Adapters Support Guide.

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:

 

 

Fibre Channel Topology of HBA

Field

Value Information

Fabric Topologies such as Public

 

Private Loop

 

 

 

 

 

 

Loop and Direct Fabric Attach

 

 

 

 

 

 

 

 

 

 

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.
