Installing the Adapter Online
The Online Addition and Replacement feature (OLAR for HP-UX 11i v1, or OL* for HP-UX 11i v2 and later
HP-UX releases) allows PCI host bus adapters to be added, or replaced, without shutting down and rebooting
the system, and without adversely affecting other system components. The system hardware uses slot-specific
power control, combined with HP-UX operating system support, to enable these features.
OLAR or OL* may not be supported on the system you plan to install an A6795A adapter in. See the HP Fibre
Channel Host Bus Adapter Support Matrix, at http://www.docs.hp.com, to confirm if OLAR or OL* is
supported.
NOTE For detailed instructions on using OLAR on HP-UX 11i v1, see Chapter 2 of Configuring
HP-UX for Peripherals, which can be accessed at http://www.docs.hp.com
For detailed instructions on using OL* on HP-UX 11i v2 and later HP-UX releases, see the
Interface Card OL* Support Guide, and the Interface Card OL* Support Matrix, which can be
accessed at http://www.docs.hp.com
NOTE rp54xx servers have slot restrictions for OLAR.
PCI slots 1 through 4 do not support OLAR.
In these servers, use PCI slots 5 through 12 for OLAR.
IMPORTANT Superdome systems are not intended for access by users. HP recommends that Superdome
systems only be opened by a qualified HP engineer. Failure to observe this requirement can
invalidate any support agreement or warranty to which the system owner might otherwise be
entitled.

Verifying Installation
1. To verify the adapter installation, enter the command:
ioscan -f
2. Verify that the following drivers appear for each installed adapter. If all drivers display, proceed to the
next section, Verifying Connectivity.
The ioscan output might look like the following. The third column represents the hardware path of the
slot in which the adapter is installed. This path will be different for each installed adapter port.
3. If the correct driver is installed, but the adapter does not show it in the ioscan output, the driver is not
recognizing the adapter. Contact HP for assistance.
NOTE If the td driver for an installed Tachyon adapter (A6795A) does not display, verify that the
adapter is securely seated before taking additional action.
Verifying Connectivity
Once your HP Fibre Channel Mass Storage software and hardware is installed and running, type the
following commands to verify mass storage hardware and software installation.
1. Check the state of all Fibre Channel hardware and interfaces. Enter the ioscan command and verify that
the S/W State of all Fibre Channel hardware and interfaces is CLAIMED.
If the Fibre Channel device file has not been created, enter the following commands:
ioscan -f
insf -e
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 sdisk CLAIMED DEVICE DGC C3400WDR5
The example above is the hardware path of LUN0 of a directly attached Fibre Channel Mass Storage
device with Loop ID of 1. For details on interpreting hardware paths for Fibre Channel devices, see

Domain The value depends
on the Fibre
Channel topology of
the HBA.
This field is typically the Domain ID
of the switch to which the target
device is attached. The value of
this field is taken from the most
significant byte of the N_Port ID of
the target device.
This field is set to 8.
For historical reasons, 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; doing so is
unsupported and will not work.
Area The value depends
on the Fibre
Channel topology of
the HBA.
This field is taken from the second
byte of the N_Port ID of the target
device.
On some switches, the second byte of
the N_Port ID encodes the switch
port to which the device is
connected. How this encoding is
done depends on the switch. Consult
the relevant switch manual to
interpret this field.
This field is set to 0.
Port The value depends
on the Fibre
Channel topology of
the HBA and the
target device, and on
the LUN addressing
method used.
For LUNs with Peripheral Device
Addressing, the value of this field is
always 255.
For other LUN methods, the value of
this field is the least significant byte
of the N_Port ID of the target device.
For LUNs with Peripheral Device
Addressing, the value of this field
is always 255.
For other LUN methods, the
value of this field is the Loop ID
of the target device.
Bus The value depends
on the Fibre
Channel topology of
the HBA and the
target device, and on
the LUN addressing
method used.
For LUNs with Peripheral Device
Addressing, the value of this field is
the upper 4-bits of the least
significant byte of the N_Port ID of
the target device.
For LUNs with Peripheral Device
Addressing, the value of this field
is the upper 4-bits of the Loop
ID of the target device.
For LUNs with Logical Unit Addressing, the value is the Bus Number
field of the Logical Unit Number.
For LUNs with Volume Set Addressing (Flat Space Addressing), the
value is bits 7 - 13 of the Logical Unit Number
Field Value Information
Fibre Channel Topology of HBA
Fabric Topologies such as Public
Loop and Direct Fabric Attach Private Loop

HP-UX Installation
Interpreting Hardware Paths
Chapter 1 15
NOTE Fibre Channel devices can connect to a Fabric using either Direct Fabric Attach or Public Loop.
Different devices may have different types of connections to the same Fabric, for example an
HBA may have a Direct Fabric Attach connection to the Fabric, while an array has a Public
Loop connection to the same Fabric. In other words, in a Fabric, the Fibre Channel Topology of
an HBA may be different from the Fibre Channel Topology of devices seen by that HBA.
Public Loop devices have an Arbitrated Loop Physical Address (AL_PA). The AL_PA usually
appears in the least significant byte of the device's N_Port ID. Direct Fabric Attach devices do
not have an AL_PA and the least significant byte of their N_Port ID is usually 0. This is
dependent on the switch implementation and not all switches adhere to this scheme.
Some switches allow devices in Private Loop mode to connect to a Fabric. In these situations,
the switch typically translates the private loop device as either a Public Loop or Direct Fabric
Attach device to the rest of the Fabric. The switch also typically translates the rest of the Fabric
as Private Loop devices to the Private Loop device.
Target The value depends
on both the Fibre
Channel topology
and the LUN
addressing method
used.
For LUNs with Peripheral Device
Addressing, the value of this field is
the lower 4-bits of the third byte of
the N_Port ID of the target
device.
This field usually corresponds to the
Arbitrated Loop Physical Address
(AL_PA) of the target device.
With Peripheral Device
Addressing, the value of this field
is the lower 4-bits of the Loop ID
of the target device.
For LUNs with Logical Unit Addressing, the value is the Target field of
the Logical Unit Number.
For LUNs with Volume Set Addressing (Flat Space Addressing), the
value is bits 3 - 6 of the Logical Unit Number.
LUN The value of this field depends only on the LUN addressing method used, see below.
