A6795A Fibre Channel Adapter Installation
1. Check the state of all Fibre Channel hardware and interfaces. Enter
the ioscan command and verify that the Hardware State and the
HW-Interface State are CLAIMED.
If the Fibre Channel device file has not been created, enter the
following commands:
insf -e
ioscan -f
2. Verify that all devices you attached to the Fibre Channel adapter are
listed in the ioscan output. For example, if you have a direct attach
Fibre Channel device attached to the system, the ioscan output
might look like the following:
8/12.8.0.255.0.1.0

details on interpreting hardware paths for Fibre Channel devices,
see the sections on interpreting hardware paths below.
3. HP Fibre Channel Mass Storage installation is verified if the ioscan
output lists all mass storage devices attached to the adapter. If all
attached devices are not listed or appear as UNCLAIMED, see the
Troubleshooting and Maintenance chapter of the HP Fibre Channel
Adapters Support Guide.
Interpreting the Hardware Path (private loop
devices)
18
Chapter 1
A6795A Fibre Channel Adapter Installation
Interpreting the hardware path in the ioscan output for Fibre Channel
devices is different from interpreting ioscan output for other types of
devices. The Fibre Channel hardware path format for a private loop
device is as follows:
Figure 1-2
Hardware Path for Private Loop Devices
Bus_Converter
Adapter
Protocol_Type
Area
Port
Bus
Target
LUN
8/12.8.0.255.0.1.0
Each field in the hardware path is described below:
Bus_Converter
One of several possible bus converters providing the
interconnect to the bus to which the Fibre Channel
adapter is connected.
Adapter
Module address of the Fibre Channel adapter.
Protocol_Type
Fibre Channel protocol type. For Fibre Channel Mass
Storage, the protocol type is FCP and is represented by
a value of 8.
Area
The area portion (second byte) of the N_Port Identifier.
For a private loop topology, the value is 0.
Port
When interpreting the hardware path for Fibre
Channel Mass Storage devices, arrays are defined as
having addressable controllers, and non-arrays are
defined as not having addressable controllers.
For hardware paths associated with non-array LUNs,
the port element of the hardware path is set to the
value 255 (255 for direct connect controller).
For hardware paths associated with array LUNs, the
port element of the hardware path is set to the Loop ID
(for a private loop topology).
Bus
Chapter 1
For hardware paths associated with non-array LUNs,
the bus element of the hardware path gets its value
from the upper four bits of the port portion of the
N-Port Identifier.
19
A6795A Fibre Channel Adapter Installation
For hardware paths associated with array LUNs, the
bus element of the hardware path is set as:
Target
•
The bus number (0-7) for an array device using the
logical unit addressing method
•
The value of the upper seven bits of the 14-bit
volume number for an array device using the
volume set addressing method.
For hardware paths associated with non-array LUNs,
the target element of the hardware path gets value
from the lower four bits of the port portion of the
N_Port Identifier.
For hardware paths associated with array LUNs, the
target element of the hardware path is set as follows:
LUN
•
The target number (0-15) for an array device using
the logical unit addressing method.
•
The value of bits 6-3 (0 is the least significant bit of
the 14-bit volume number) for an array device
using the volume set addressing method.
For hardware paths associated with non-array LUNs,
the LUN element of the hardware path is the LUN ID
(0-7) for the LUN.
For hardware paths associated with array LUNs, the
LUN element of the hardware path is set as follows:
•
The LUN ID (0-7) of the LUN for an array device
using the logical unit addressing method.
•
The value of bits 2-0 of the 14-bit volume number
for an array device using the volume set addressing
method.
The following is an example of the hardware path for a Fibre Channel
SCSI Device (K-class system).
LUN 0 (base address) of a direct connect device in an arbitrated loop:
8/4.8.0.255.0.0.0

Chapter 1
A6795A Fibre Channel Adapter Installation
Interpreting the Hardware Path (public loop
devices)
The following illustration is the Fibre Channel hardware path format for
a public loop device:
Figure 1-3
Hardware Path for Public Loop Devices
Adapter
Domain Area Port
Bus Target LUN
0/1/2/0.1.19.255.15.4.0
Each field in the hardware path is described below:
Adapter
Module address of the Fibre Channel adapter.
Domain
Domain ID or Fabric ID (8 is reserved for private loop).
A domain can be defined as two or more nodes
connected by an interconnect subsystem. In a fabric
environment, a domain is generally associated with the
physical instance of a switch.
Area
The area portion (second byte) of the N_Port Identifier.
In a fabric environment, the area ID is generally
associated with a physical port on a switch. (For a
private loop topology, the value is 0).
In the above ioscan example, the area ID 19 is not the
actual port number. Some switches place a fixed “1” in
the upper four bits of the area field (0001xxxx) and
shows the value of this field as hexadecimal. However,
ioscan shows a decimal value for this field. Because of
the fixed “1” in this position, you must subtract decimal
16 from the number 19 to get the actual port number,
which is 3 (19 - 16 = port 3).
Chapter 1
Port
Set to 255 for Peripheral Device Addressing.
Bus
The bus element of the hardware path gets its value
from the upper four bits of the AL_PA (not the
Loop_ID).
21
A6795A Fibre Channel Adapter Installation
Target
The target element of the hardware path gets its value
from the lower four bits of the AL_PA (not the
Loop_ID).
In the above example, the AL_PA = 15.4 = E4 hex = 228
decimal = switch setting of 2).
LUN
The LUN element of the hardware path is the LUN ID
(0-7) of the LUN.
