Power ON (after firmware initialization) 2 Flash/s 2 Flash/s Alternate flashing. This state changes to not-initialized state in 2-3s. Both LEDs are ON steadily.
Installing the Adapter Some motherboards have two kinds of PCI bus slots: master and slave. The AB68A6A must be in a PCI bus master slot. (Some motherboards have PCI bus master slots that are shared with onboard devices. The AB68A6A does not work in shared slots.) PCI connectors vary among system adapter manufacturers. The AB68A6A 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.
Installing the Adapter Installing the Adapter 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.
Installing the Linux Driver 3 This chapter provides instructions for installing the Linux driver for the A6826A HBA on an already installed Red Hat Enterprise Linux (Red Hat EL), kernel 2.4x or SUSE Linux Enterprise Server (SUSE SLES) for 64-bit Itanium system. The software kit for this HBA can be obtained from the HP website: http://h18006.www1.hp.com/storage/saninfrastructure.html. This section provides instructions for installing the qla2300 driver into a Linux operating system.
Installing the Linux Driver Installing the Driver 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. The driver RPM packages have prebuilt driver binaries, source code, and driver startup utilities. They are available for Red Hat ELAS and SUSE SLES. To install a RPM, copy the RPM package file to your system and enter the following command: # rpm -ivh < package_name>.
Installing the Linux Driver Changing Driver Parameters for HP StorageWorks XP Systems If you are using the failover functionality built into the qla2x00 driver for HP XP storage arrays, you must change certain driver parameters. To do so, you can either run a script or manually make the changes. Changing Parameters with a Script 1. Enter the following command: # hp_fccfg.sh 2. Choose option 6. 3. Enter Y when prompted if you want to enable failover functionality 4.
Installing the Linux Driver Building a Driver from the Sources If your Linux kernel version does not match the prebuilt driver binaries, you need to build the driver in your configuration locally. To build a single-processor version of the qla2300 driver, see the section Building a Uniprocessor Version of the Driver on page 26. To build a symmetric multiprocessor (SMP) version of the qla2300 driver, see the section Building a Multiprocessor Version of the Driver on page 27.
Installing the Linux Driver Building a Multiprocessor Version of the Driver Perform the following steps to build an SMP version of the qla2300 driver: 1. If not already installed, extract the kernel-header and kernel-source RPM files from your Linux CD-ROM distribution. For example: # cd /mnt/cdrom/RedHat/RPMS # rpm -iv kernel-headers*.rpm # rpm -iv kernel-source*.rpm 2. Change to the Linux source directory. For Red Hat, enter: # cd /usr/src/linux-2.4 For SUSE SLES, enter: # cd /usr/src/linux 3.
Installing the Linux Driver 6.
Installing the Linux Driver 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 binary was installed from the RPM, 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.
Installing the Linux Driver 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 the section Building a Ramdisk Image to Load the qla2300 Driver on page 30. To load the qla2300 driver manually, see the section Loading and Unloading the qla2300 Driver Manually on page 31.
Installing the Linux Driver 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.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.
Installing the Linux Driver Note: HP recommends loading the driver using the modprobe command so that any driver parameter value specified in the /etc/modules.conf file takes effect. 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/ drivers/addon/qla2300 # mv qla2300.o qla2300_rh.
Installing the Linux Driver System Driver Parameter max_scsi_luns Support for multiple LUNs can be configured in one of three ways. Currently, the maximum number of LUNs that can be scanned for each device is 128. Note: If you have multiple HBAs, set max_scsi_luns to the largest number of LUNs supported by any one of these HBAs.
Installing the Linux Driver Driver Command Line Parameters The following command line options are available: ■ Verbose —This option provides detailed debug information. For example: # insmod qla2300.o options = verbose Waiting for LIP to complete.... scsi%d: Topology - %s, Host Loop address 0x%x scsi(%d): LIP occurred scsi(%d): LIP reset occurred ■ Quiet—This option keeps the driver from displaying. For example: # insmod qla2300.
Installing the Linux Driver Proc Filesystem Support The /proc file system for the QLA2300 driver can be found in the /proc/scsi/qla2300/ directory. This directory contains an entry for each SCSI HBA in the system. Each entry presents information about the adapter and transfer statistics for each discovered LUN.

Troubleshooting 4 Three basic types of installation problems can cause the A6826A HBA to function incorrectly. This chapter includes: ■ Hardware Problem Checklist, page 37 ■ System Configuration Problems, page 38 ■ Fibre Channel Problem Checklist, page 38 The following sections provides checklists to help you determine why the HBA is not functioning properly.
Troubleshooting System Configuration Problems If you have problems with the motherboard connection, the adapter may not function properly. All PCI-compliant and PCI-X–compliant systems automatically detect 32-bit or 64-bit adapters 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.
Configuring Adapters A This appendix describes how to configure the A6826A HBA. The A6826A functions correctly on Linux Itanium systems using the factory default configuration settings. If you are an advanced user, you may change the configuration using the efiutil utility.
Configuring Adapters Using the efiutil Utility To configure the HBA, use the efiutil utility as follows: 1. Use the fibreutils RPM package to obtain efiutil (efiutil.efi) and the auxiliary driver, efiaux.drv as described in “Installing the fibreutils RPM” on page 24. 2. Power on the server to the EFI shell. 3. Start efiutil as follows (efiaux.drv is automatically loaded if it is needed): a. Set the drive to the boot device ( for example, fs1:). b. Change to the directory containing efiutil.
Configuration Commands B This appendix describes the efiutil commands for advanced users who want to customize the configuration of the A6826A HBA and the connected devices. Note: As described in Using the efiutil Utility, page 40 use efiutil menu to configure the HBA.
