Do the following steps and hopefully your problem will be fixed. Note, your
kernel version might be different from my notes.
1. Install kernel-devel and kernel-headers packages.
2. download the QLogic driver (qla2xxx-8.01.07.15) and extract the file into
/tmp/qlogic directory
3. issue the command ./drvsetup (which creates the directory
qla2xxx-8.01.07.15)
4. run the following commands:
a) cd qla2xxx-8.01.07.15/
c) ./extras/build.sh install
d) depmod -av
5. Copy the currently booted kernel image from /boot dir to temp directory.
cp /boot/initrd-2.6.18-92.1.18.el5.img /tmp/image
6. cd /tmp/image
7. mv initrd-2.6.18-92.1.18.el5.img initrd-2.6.18-92.1.18.el5.img.gz
8. gzip -d initrd-2.6.18-92.1.18.el5.img.gz
(This will be inflated into initrd-2.6.18-92.el5.img file)
9. cd /tmp/image && cpio -i --make-directories < initrd-2.6.18-92.el5.img
10. mv initrd-2.6.18-92.el5.img ../ (VERY IMPORTANT STEP!!)
11. vi "init" file and add:
a) Add the following EIGHT lines: (Make sure the orders are as below)
echo "Loading intermodule.ko module"
insmod /lib/intermodule.ko
echo "Loading qla2xxx.ko module"
insmod /lib/qla2xxx.ko
echo "Loading qla2400.ko module"
insmod /lib/qla2400.ko
echo "Loading qla2xxx_conf.ko module"
insmod /lib/qla2xxx_conf.ko
just below the line ' insmod /lib/sd_mod.ko '
b) Delete the following TWO lines:
echo "Loading scsi_transport_fc.ko module"
insmod /lib/scsi_transport_fc.ko
12. cp qla2400.ko file from /lib/modules/`uname
-r`/kernel/drivers/scsi/qla2xxx to /tmp/image/lib dir.
13. cp qla2xxx.ko file from /lib/modules/`uname
-r`/kernel/drivers/scsi/qla2xxx to /tmp/image/lib dir.
14. cp qla2xxx_conf.ko file from /lib/modules/`uname
-r`/kernel/drivers/scsi/qla2xxx to
/tmp/image/lib dir.
15. cp /lib/modules/`uname -r`/kernel/kernel/intermodule.ko /tmp/image/lib
16. Make the new initial Ram image:
cd /tmp/image && find . | cpio -o -H newc | gzip -9 -n >
../initrd-`uname -r`-QLFO.img
17. cd .. && cp initrd-`uname -r`-QLFO.img /boot
18. vi /boot/grub/menu.lst file and add the new QLogic driver compiled
initrd entry.
19. Reboot
