Interpreting Hardware Paths
Example 2-1, Example 2-2 and Example 2-3 illustrate the Fibre Channel hardware path format:
Example 2-1 Hardware Path for a Public Loop Device
Example 2-2 Hardware Path for a Direct Fabric Attach Device
Example 2-3 Hardware Path for a Private Loop Device
Table 2-5 describes each field in the hardware path.
Table 2-5 Hardware Path Field Descriptions
Field Value
Fibre Channel Topology of HBA
Fabric Topologies Private Loop
Adapter The hardware path of the Fibre Channel adapter through which the Logical Unit Number
(LUN) is seen. For multiport adapters, this field describes a specific port on the adapter.
Domain Dependent on the
Fibre Channel
topology of the HBA.
Typically the Domain ID of the
switch to which the target device is
attached, taken from the most
significant byte of the N_Port ID of
the target device.
8
HP-UX uses a Domain ID of 8 to
indicate private loops. Fibre
Channel switches seen by
HP-UX hosts cannot be
configured with domain ID of 8.
