CentOS - Sep 2010 - HP ML110 G6: how to update kernel with HP hpahcisr raid driver installed

Hi!

I have install Centos 5.5 on HP ProLiant ML110 G6
with RAID-1 hardware active.

(00:1f.2 RAID bus controller: Intel Corporation 5 Series/3400 Series Chipset
SATA RAID Controller (rev 05))

I have follow this suggest:
http://h20000.www2.hp.com/bizsupport/TechSupport/SoftwareDescription.jsp?lang=en&cc=us&prodTypeId=15351&prodSeriesId=3984625&prodNameId=3984626&swEnvOID=4006&swLang=13&mode=2&taskId=135&swItem=MTX-d7a175cef91649e7ab86653b61

... start with "linux dd" and, at the end of setup, 
install the hpahcisr into kernel 2.6.18-194.el5PAE

But after reboot if I run a "yum update" and reboot, the new kernel
not
contain the driver hpahcisr for new kernel and I get a kernel panic. 

The question is:

How to update to last kernel without lost the proprietary driver?

It's possible?

Where is the new driver for new kernel?

Many thanks.

The README files says:

"The install script will install the hpahcisr loadable
object modules into the /lib/modules directory for each kernel
for which a driver object module is present in this package and
exists on the system.  Then it will make a new initrd 
(initial RAM disk) image for the running kernel, if a driver for
the running kernel was installed.  Then, it will update the LILO
or GRUB configuration, as directed, adding a new entry to use the
new initrd image.  If there were already hpahcisr loadable
object modules present in the kernel libraries, these will be backed
up under /use/src/HP/driver_backup."

"driver object module is present in this package" =>
$ find . | grep ko | awk -F/ ' { print $4 } ' | sort
...
2.6.18-194.el5
2.6.18-194.el5PAE
2.6.18-194.el5xen
...

Maybe run once more the install script but, if your kernel version is not 
listed, I do not know if it will help...
Or, maybe you could copy the module in /lib/modules/... and make the initrd by 
hand and hope it works...
Or just disable the "fake" hardware RAID and use software RAID (I am
afraid of
cheap raid)...

Of course not. You installed a proprietary driver, that is *not* part of 
the new kernel. Why would you think it should magically be part of the 
new kernel? Look at /boot, and you'll see more than one kernel file. The 
configuration files for *one* kernel make it  aware of your driver; the 
new one has no clue, *and* some of the shared libraries may/will not 
match, so of course you have to reinstall.

Where'd you get the original? Does installation of it build the driver, 
the way, for example, I have to rebuild a years-old driver for my Nvidia 
card at work, every time I update the kernel?
