AH400A/AH401A - HP PCIe 8Gb 1 port, 2 port, and 4Gb Fibre Channel QLogic HBAs using Linux, Windows, and HP-UX OS's Installation Guide, October 2008

2. Verify that all devices you have attached to the Fibre Channel adapter are listed in the
ioscan output. For example, if you have a direct attach Fibre Channel device installed in
the system, the ioscan output may look like the following:
8/12.8.0.255.0.1.0 sdisk CLAIMED DEVICE DGC C3400WDR5
The example above is the hardware path of LUN0 of a directly attached Fibre Channel Mass
Storage device with a Loop ID of 1.
If all the attached devices are listed and appear as CLAIMED, the HP Fibre Channel Mass Storage
installation is verified.
If all the attached devices are not listed or appear as CLAIMED, see the Troubleshooting and
Maintenance chapter of the HP Fibre Channel Adapters Support Guide.
Interpreting hardware paths
The following examples illustrate the Fibre Channel hardware path format.
Example 4-4 Hardware path for a direct fabric attach device
Example 4-5 Hardware path for a private loop device
Table 7 describes each field in the hardware path.

This is the hardware path of the Fibre Channel adapter that the Logical Unit Number (LUN) is seen. For
multiport adapters, this field describes a specific port on the adapter.

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.
Typically the Domain ID of the
switch the target device is
attached, taken from the most
significant byte of the N_Port ID
of the target device.
Dependent on the Fibre Channel
topology of the HBA.
