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.

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_parmscript 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:
/lib/modules/<kernel_release_version>/kernel/drivers/addon/…
Download from Www.Somanuals.com. All Manuals Search And Download.
Perform the following steps to install the qla2300 driver on the boot drive:
2. Copy the qla2300.obinary file to the following directory:
/lib/modules/<kernel_release_version>/kernel/drivers/scsi
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
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.oto /lib/modules/<kernel_release_version>/drivers/scsi.
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 -aor make sure the following line is in the
/lib/modules/<kernel_release_version>/modules.depfile:
/lib/modules/<kernel_release_version>/kernel/drivers/scsi/
qla2300.o: /lib/modules/<kernel_release_version>/kernel/
drivers/scsi/scsi_mod.o

4. Build the ramdisk image file:
• For a single-processor system, enter the following commands, replacing x.x.xx–x.x with your
Linux version number:
/sbin/mkinitrd /boot/newinitrd-image x.x.xx-x.x
• For a multiprocessor system, enter the following commands, replacing x.x.xx–x.x with your
Linux version number.
/sbin/mkinitrd /boot/newinitrd-image x.x.xx-x.xsmp
5. Configure the boot loader with the new ramdisk image:
a. Modify the elilo.conffile 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
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.
To load the qla2300 driver:
1. Manually install the driver binary:
a. Copy qla2300.oto the following directory:
/lib/modules/<kernel_release_version>/kernel/drivers/scsi
b. Update the dependency file.
You can either run depmod -aor make sure that the following line is in the file
/lib/modules/<kernel_release_version>/modules.dep
/lib/modules/<kernel_release_version>/kernel/drivers/scsi/
qla2300.o:/lib/modules/<kernel_release_version>/kernel/drivers/scsi/scsi
_mod.o
c. Enter the following command to load the driver:
# modprobe qla2300
d. Under the directory that contains the qla2300.o file, you can also enter the following

e. If your system has a previous version of the qla driver, rename the old binary included in the
original distribution to ensure that it does not interfere with the updated version as follows:
# cd /lib/modules/<kernel_release_version>/kernel/
drivers/addon/qla2300
# mv qla2300.o qla2300_rh.o
After renaming the older driver version, load the new driver using modprobeafter updating
the dependency file.
2. To manually unload the qla2x00 driver, enter the following command at the command prompt:
# modprobe –r qla2300
Configuring the driver
The following sections include driver configuration information.
System driver parameter max_scsi_luns for Red Hat EL 2.1 kernels
You can configure support for multiple LUNs on Red Hat EL 2.1 kernel systems in one of the
following ways:
NOTE: If you have multiple HBAs, set max_scsi_luns to the largest number of LUNs supported by
any one of these HBAs.
• To configure multiple LUN support during boot time, enter the following command at the boot
prompt:
boot: linux max_scsi_luns=128
• If the SCSI Mid-Layer is compiled as a module, add the following line to the
/etc/modules.conf file to scan for multiple LUNs at each boot:
options scsi_mod max_scsi_luns=128
• If the SCSI Mid-Layer is not compiled as a module, the boot loader can be configured to scan
for multiple LUNs each time the system boots.
To complete the configuration, perform the following steps:
1. Add the following line to each of the kernel images listed in the elilo.conf file:
append=”max_scsi_luns=128”
2. Reboot the system.

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.

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?

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
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.
NOTE: For more information on static electricity, or assistance with product installation,
contact your HP-authorized reseller.
