• Installation prerequisites, page 12
• Installing the HBA, page 13
See the host documentation for installing the HBA.
CAUTION: Disconnect the host from the power source before installing the HBA. To reduce the risk
of personal injury from hot surfaces, allow the internal server or workstation components to cool
before touching.
CAUTION: Electrostatic discharge (ESD) can damage electronic components. Be sure you are
properly grounded before beginning this procedure. See ”Regulatory compliance and safety” on
page 35 for related ESD information.
A6826A PCI-X host bus adapter for Itanium Linux systems installation guide11
Installation prerequisites
Before you begin, make sure you have the following:
• A screwdriver (Phillips #1).
• An optical multimode cable with an LC-style duplex connector.
• Each HBA has a unique serial number that is located on the bottom of the HBA. Check the HBA
and record its serial number, in the unlikely event that the NVRAM is corrupted.
HBA components
Figure 1 shows the HBA components that are referenced throughout this chapter.
LED Indicators
Figure 1 A6826A components
Installing the HBA12
Jumpers
The jumpers on the HBA are set to the default state of the laser and are set at the factory with a
jumper plug on pins 1-2 of the J3 jumper and on pins 1-2 of the J4 jumper.
CAUTION: Changing the jumper settings can result in the HBA being inoperable.
Before you begin installation
The HBA is self-configuring. However, some motherboards require manual configuration. See the
documentation supplied with your computer, or contact your computer dealer to determine if your
motherboard requires configuration.
Some motherboards have two kinds of PCI bus slots: master and slave. The A6826A must be in a
PCI bus master slot. (Some motherboards have PCI bus master slots that are shared with onboard
devices. The A6826A does not work in shared slots.)
PCI connectors vary among system HBA manufacturers. The A6826A is a 64-bit PCI device that can
function in a 32-bit PCI slot; the slot conforms to the PCI specification. The rear edge of the PCI slot
is notched.
CAUTION: If you try to install the HBA in a PCI slot that does not conform to the PCI specification,
you may damage the device.
PCI and PCI-X slots look the same. If the server contains both PCI and PCI-X slots, see the server
manufacturer’s instructions to determine the slot type.
The A6826A is designed and tested to operate at PCI bus speeds of up to 133 MHz.
Installing the HBA
To install the HBA:
1. Check the motherboard and make any necessary configuration changes to accommodate the
HBA.
2. Power down the peripherals, then turn off the computer.
3. Remove the computer cover and save the screws.
4. Choose any PCI bus slot that supports bus mastering.
5. Most motherboards automatically assign an IRQ level and interrupt line; if your motherboard
does not, you must assign the IRQ level and use interrupt line A for this slot.
6. Remove the slot cover for the slot in which you will install the HBA.
7. Place the HBA in the slot. Carefully press the board into the slot until it seats firmly.
8. Secure the HBA to the chassis. Follow the server manufacturer’s instructions.
9. Connect the appropriate cable from the devices to the corresponding LC-connector.
10.Carefully reinstall the computer cover. Insert and tighten the computer cover screws.

• Configuring the driver, page 20
.
A6826A PCI-X host bus adapter for Itanium Linux systems installation guide15
Installing the driver kit
HP recommends installing the complete driver kit for this HBA. The kit contains the HBA driver and
the utilities that you need to deploy the A6826A HBA on Linux.
NOTE: Using the following procedure installs the RPM and fibreutils.
To install the complete HP driver kit:
1. Copy the .gz file to your system.
2. Enter the following commands:
# tar -zxvf hp_qla2x00<version_info>.tar
3. Run the set_parm script to initialize the default HBA settings.
# ./set_parm
4. Enter the installation command:
# ./INSTALL
See the README file for more information.
NOTE: You must install the gcc compiler, kernel, headers, and the kernel development or kernel
sources packages before installing the driver kit.
Using RPM
The RPM Package Manager (RPM) is a package management system that lets you easily install Linux
software. Using RPM, you can install software in prebuilt bundles called RPM packages. This section
is included for reference for separate RPM installations you may need to install in the future.
For example, to install a RPM, copy the RPM package file to your system and enter the following
command:
# rpm -ivh <package_name>.rpm
To install the Linux HBA driver RPM, enter the following command:
#rpm -ivh qla2x00-<version_info>.rpm
To upgrade a RPM package, copy the RPM package file to your system and enter the following
command(s):
To uninstall a RPM package, enter the following command:
# rpm -e <package_name>
Installing the Linux driver16
Using fibreutils RPM
HP recommends using the fibreutils utility that is installed by the driver kit. It contains useful utilities
for managing fibre-attached storage. To manually install this RPM, enter the following command:
# rpm -ivh fibreutils-<version>.rpm
For more information about fibreutils, see the file /opt/hp/hp_fibreutils/README.
Changing driver parameters
To change driver parameters:
1. Run the set_parm script located in the /opt/hp/src… directory.
2. Reboot the system.
NOTE: You may not be able to unload the qla2200 and/or qla2300 modules if there is a process
or file system using a device that is attached to the A6826A HBA.
Installing the driver on the boot drive
NOTE: The following instructions for installing the driver and loading and unloading the driver are
required only if the driver has been built from source. If the driver was installed from an RPM or
driver kit, the driver loads at boot time.
Before installing the driver, note the following:
• The A6826A HBA must be installed in the system before installing the qla2300 driver.
• The <kernel_release_version> is the Linux kernel release version of your system.
• In the following example, the path to your driver may be:
3. At the command prompt, enter the following command to update the module dependency:
# depmod -a
The qla2300 driver is now installed on your boot drive. However, the driver must be loaded
before the system can access the devices attached to the HBA.
Loading the driver
The qla2300 driver must be loaded before the system can access the devices attached to the
A6826A HBA. To build a ramdisk image to automatically load the qla2300 driver at boot time, see
”Building a ramdisk image to load the qla2300 driver” on page 18. To load the qla2300 driver
manually, see ”Loading and unloading the qla2300 driver manually” on page 19.
Building a ramdisk image to load the qla2300 driver
You can load the qla2300 driver at boot time using a ramdisk image as follows in this Red Hat
example.
1. For Red Hat, add the following line to the file /etc/modules.conf:
alias scsi_hostadapter qla2300
NOTE: If there are other SCSI HBAs installed on your system and the scsi_hostadapter alias
is used, define a different alias (for example, scsi_hostadaptern. The n is a number in the
range 1–9).
2. Build a new ramdisk image that contains the qla2300.o object file. Copy the driver binary file
qla2300.o to
NOTE: The <kernel_release_version> is the Linux kernel release version of your system.
3. Add the dependency for the qla2300 driver and build the ramdisk image:
You can either run depmod -a or make sure the following line is in the
/lib/modules/<kernel_release_version>/modules.dep file:
5. Configure the boot loader with the new ramdisk image:
a. Modify the elilo.conf file to load the new ramdisk image by changing the following line:
initrd=/boot/initrd_file_name
For example:
initrd=/boot/newinitrd-image
b. Reboot the system. Select the kernel with the new ramdisk image.
Loading and unloading the qla2300 driver manually
Before loading the driver manually, first build the driver from sources as described in ”Building a
uniprocessor version of the driver” on page 32 or in ”Building a multiprocessor version of the
driver” on page 33.
After manually loading the qla2300 driver, you can access the devices and unload the driver
manually without rebooting the system. The driver is also unloaded each time the system is
rebooted.
• Quiet—This option keeps the driver from displaying. For example:
# insmod qla2300.o ql2xopts = quiet
Proc filesystem support
The /proc filesystem for this driver resides in the /proc/scsi/ directory. It contains entries for
each SCSI HBA channel in the system. Each entry presents information about the HBA and
information for each discovered LUN.

4Troubleshooting
This chapter includes the following information to help you determine why the HBA is not
functioning properly.
• Hardware problem checklist, page 24
• System configuration problems, page 24
• Fibre Channel problem checklist, page 24
• POST conditions and results, page 25
A6826A PCI-X host bus adapter for Itanium Linux systems installation guide23
Hardware problem checklist
Check the following to determine if there is a hardware problem:
• Are all of the circuit cards installed securely in the system?
• Are all of the cables securely connected to the correct connectors? Be sure that the FC cables
that attach from the HBA connectors to the device are connected correctly. For example, the
optical transmit connector on the HBA must be connected to the optical receive connector on the
device. Some connectors require a firm push to ensure proper seating. An easy way to check for
correct seating is to switch the connectors on either the HBA or the device, then reboot the
system.
• Is the HBA installed correctly in the PCI slot? Is it seated firmly in the slot?
• Check for interference due to nonstandard PCI connectors.
• Is the data rate setting correct? See ”Configuring the HBA” on page 27 for information about
configuring the HBA.
• Are all external peripherals properly powered up? See ”Configuring the HBA” on page 27 for
information about displaying attached devices.
System configuration problems
If you have problems with the motherboard connection, the HBA may not function properly.
All PCI-compliant and PCI-X–compliant systems automatically detect 32-bit or 64-bit HBAs and set
the appropriate bus speed (for example, 33 MHz or 133 MHz). Check the motherboard for proper
configuration.
See the documentation supplied with your computer, or contact your computer dealer to determine
if your motherboard requires special configuration.
Fibre Channel problem checklist
Check the following Fibre Channel components to determine if the problem is Fibre
Channel-related.
• Were all of the FC devices powered up before you powered up the server?
• Are all cables properly connected?
• Have you configured the RAID controller using the utilities provided by the manufacturer?
• If the Fibre Channel switch supports zoning, is it configured correctly for zoning?
Troubleshooting24
POST conditions and results
Figure 1 on page 12 shows the position of the POST LED indicators.
If the LEDs indicate a failure during POST:
1. Make sure the HBA is seated firmly in the PCI slot.
2. Verify that the fiber cable connection to the HBA is secure.

Electrostatic discharge
To prevent damage to the system, be aware of the precautions you need to follow when setting
up the system or handling parts. A discharge of static electricity from a finger or other
conductor may damage system boards or other static-sensitive devices. This type of damage
may reduce the life expectancy of the device.
To prevent electrostatic damage, observe the following precautions:
• Avoid hand contact by transporting and storing products in static-safe containers.
• Keep electrostatic-sensitive parts in their containers until they arrive at static-free
workstations.
• Place parts on a grounded surface before removing them from their containers.
• Avoid touching pins, leads, or circuitry.
• Always be properly grounded when touching a static-sensitive component or assembly
(see ”Grounding methods” on page 38).
Grounding methods
There are several methods for grounding. Use one or more of the following methods when
handling or installing electrostatic-sensitive parts:
• Use a wrist strap connected by a ground cord to a grounded workstation or computer
chassis. Wrist straps are flexible straps with a minimum of 1 megohm (±10 percent)
resistance in the ground cords. To provide proper ground, wear the strap snug against the
skin.
• Use heel straps, toe straps, or boot straps at standing workstations. Wear the straps on
both feet when standing on conductive floors or dissipating floor mats.
• Use conductive field service tools.
• Use a portable field service kit with a folding static-dissipating work mat.
If you do not have any of the suggested equipment for proper grounding, have an
HP-authorized reseller install the part.
