PSP & kernel upgrade

Hi,

We are running RHEL 4 on a couple of blade servers (BL20p G3) that are running Proliant-Supp Pack 7.80.

Until now I never considered performing a kernel update...I was wondering if I'm going to break my kernel modules (ethernet driver, qlogic hba drivers provided by PSP etc) by upgrading the kernel? The major & minor version stays the same: 2.6.9

These modules were compiled from source as I understand and I had to install kernel source pacakges when I installed them thru PSP...).

Please share your experiences.

Thanks,
Jorge

Re: PSP & kernel upgrade

You can combine 2 updates - first update kernel to new version, and after that upgrade PSP to latest version (8.10) - http://h20000.www2.hp.com/bizsupport/TechSupport/SoftwareIndex.jsp?lang=en&cc=us&prodNameId=3716247&prodTypeId=18964&prodSeriesId=3716246&swLang=13&taskId=135&swEnvOID=2025


No matter that major and minor version is the same on both kernels, there can be many changes, related to drivers, included in PSP.

Re: PSP & kernel upgrade

Thanks Ivan. That sounds like a good idea. It's been a year since we've been using 7.80.

Is it a matter of running PSP again and select the rpm's I want to install/reinstall? Should I remove the pertinent rpms before?

Best regards,
Jorge

Re: PSP & kernel upgrade

After a quick look at install script found that:
# if the package version is greater than the installed
# version then do the RPM install.
./vercmp ${curver%%\.[A-Za-z]*} ${newver%%\.[A-Za-z]*} > /dev/null 2>&1
isVersionNewer=$?
[ $isVersionNewer -eq 1 ] && installRPM=`expr 1`

# if installRPM is equal to one, then installation
# proceeds, else skip installation
if [ $installRPM -eq 1 ]
then
rpm -Uv --nodeps --force $i >/dev/null 2>&1
fi


If version is newer - it will be updated.
