The kernel the HP DL380 is running on is
Linux 2.6.9-34.ELsmp #1 SMP Fri Feb 24 16:54:53 EST 2006 i686 i686 i386 GNU/Linux
How do apply the latest patches on the DL380 and do I need to reboot the system for the patches to take effect?
Solved! Go to Solution.

Re: How to patch a HP Proliant DL380 system
up2date will work fine.
Make sure any third party applications you have installed will work with the latest RH update.
An upd2date run will take you to RH 4 update 5, which some ISV's have yet to certify.

Re: How to patch a HP Proliant DL380 system
We update/patch our linux servers using a master satellite server. So at the client side ;
The file /etc/sysconfig/rhn/up2date should have the below listed entries valued as shown, this will prevent the ├в Kernel Packages├в from getting upgraded automatically.
# grep kernel /etc/sysconfig/rhn/up2date
removeSkipList=kernel*;
pkgSkipList=kernel*;

Re: How to patch a HP Proliant DL380 system
My question is what is the distinction between the above terms?
When I ran "up2date -u" will it only up2date patches and will it also install critical updates?
Will "up2date -u" update the kernel too or is there a separate command to update the kernel?
How would I know when kernel updates are required and how do I perform ernel updates?

Re: How to patch a HP Proliant DL380 system

Does both
Will "up2date -u" update the kernel too or is there a separate command to update the kernel?
Kernel also get updated unless we SKIP using some config files.
How would I know when kernel updates are required and how do I perform kernel updates?
IN our case we have a satellite server which communicae to the node and from there i can see what is due to upgrade.
You may check with Redhat(through web too).Or we can help you out throug forum if you provide enough details.
Determine which kernel packages are installed.
#rpm ├в qa|grep ├в i kernel
kernel-hugemem-2.4.21-27.EL
kernel-smp-2.4.21-27.EL
kernel-2.4.21-27.EL
kernel-utils-2.4-8.37.12
Download the required RPMs,
Install the new Kernel (use ├в i instead of ├в U, as we want to keep the copy of OLD Kernel rather than upgrading it).
If the system is multiprocessor, then install the kernel-smp packages, and upgrade the kernel-utils packages.
Install the used kernel newer package by rpm -ivh & rpm -Uvh kernel-utils*
Verify the Boot Loader, and update it accordingly to point to the new kernel.
/etc/grub.conf
Reboot the server.

Re: How to patch a HP Proliant DL380 system
Yes, 'kernel*' is usually in the 'Skip' list, but using 'up2date -u kernel kernel-smp' will do the required work for you without any extra steps.
'kernel*' is also in the 'Install only' list of up2date (so it will Install kernel packages, not just freshen them).
Using 'rpm -qa "kernel*"' will show you which kernel packages you have installed.

Re: How to patch a HP Proliant DL380 system
I rebooted my system so that the new updates would take effect.
I noticed messages at the completion of up2date. Please see attached file about these messages.
Please note we do not have satellite server.
I checked to determine which kernel packages are installed on the system:-
# rpm -qa | grep -i kernel
kernel-utils-2.4-8.37
kernel-2.4.21-4.EL
kernel-source-2.4.21-4.EL
kernel-smp-2.4.21-4.EL
kernel-pcmcia-cs-3.1.31-13
[root@leda root]#
Grepping the up2date for kernel packages displays the following:-
#grep -i kernel /etc/sysconfig/rhn/up2date
pkgSkipList=kernel*;
pkgsToInstallNotUpdate=kernel;kernel-modules;
removeSkipList=kernel*;
So if I wanted to update the kernel packages, how would I update it without losing the existing kernel?

Re: How to patch a HP Proliant DL380 system
upadate -ivh kernl-pkg-name do the package installation and update the /etc/grub.conf(link).
So editing the /boot/grub/brub.conf and pointing to the right/required kernel is what you have to to for that.
