Install Two HP FC1142SR 4Gb PCI-e HBA Card Using QLogic Fibre Channel HBA Driver (qla2xxx-8.02.21) in Ubuntu 8.04.1

Make Provision Driver Building Environment

1. apt-get install build-essential
2. apt-get install kernel-package
3. make sure that can find linux-source tarball (ex: linux-source-2.6.24.tar.bz2) in path: /usr/src
4. extract and decompress linux-source tarball (ex: tar -xvjf linux-source-2.6.24.tar.bz2)
5. change directory to /lib/modules/{kernel version} (ex: cd /lib/modules/`uname -r`)
6. create a link to linux-headers path with the name build. (ex: ln -s /usr/src/`uname -r` build)
7. create a link to linux-source path with the name build. (ex: ln -s /usr/src/linux-source-2.6.24 source)

Download QLogic Fibre Channel HBA Driver Source Code

1. change to your home directory
2. wget ftp://ftp.qlogic.com/outgoing/linux/beta/8.x/qla2xxx-src-v8.02.21.tar.gz
3. extract and decompress source code tarball file (ex: tar -xvzf qla2xxx-src-v8.02.21.tar.gz)

Modify The Driver Source Code

1. edit file extras/build.sh at first line "#!/bin/sh" to "#!/bin/bash"
   in Ubuntu Linux the default "sh" had been symbolic linking to "dash", there are some functions can't be executable in build.sh scrip.
2. edit file qla_def.h, remark line 33 ~ 35.
3. edit file qla_isr.c,. replace "SA_INTERRUPT|SA_SHIRQ" with "IRQF_DISABLED|IRQF_SHARED" at line 2100.
4. edit file qla_os.c, add "struct" in front of "kmem_cache *srb_cachep;" at line 40.
5. remove ones of NULL at line 5723 in file qla_os.c
6. replace "pci_module_init" with "pci_register_driver" at line 5759 in file qla_os.c
   

Get ready to build Driver

1. change user to root.
2. execute "extras/build.sh" in qla2xxx-8.02.21 directory.

Now You Can Install this Driver, If Everything is O Kay.

1. execute "extras/build.sh install" to install Driver.
2. execute "update-initramfs -v -u -k `uname -r`" to update initramfs image.

Reboot System to Test New Initial Ramdisk and Pray It Can Work..... just kindling ^_^
