This results in a kernel image that didn't quite work when you push it to clients (it causes a kernel panic). That is why I opt to do the kernel update AFTER I've pushed the images out to the clients.
You might want to confirm this.
Thanks,

Hi Julia:
I have recently updated my Oscar cluster from the RedHat 9.0 stock kernel to 2.4.20-20.9. And here's what I did:
1. Use cexec to rpm install the kernel
2. Modify /boot/grub/menu.lst accordingly (we use grub so you should edit the appropriate boot list for lilo)
3. Push the menu.lst to the nodes
4. Reboot and the new kernel should boot up.
We haven't quite figured out how to update the kernel for the image though.
To update the image you need to run:
rpm --root /var/lib/systemimager/image/X -Uvh Y.rpm (where X is your image name and Y is the rpm file)
and then probably hand edit /var/lib/systemimager/image/X/etc/systemconfig/systemconfig.conf with the correct names (it is fairly obvious). This file is run to configure the nodes after image install. (Note, you can also make changes in the override directory instead.)
Note: this is all for OSCAR 2.3, but I think that the systemimager stuff in earlier OSCAR versions was similar.
Cheers,
Bernard

Hi, All:
I have an existing OSCAR cluster (Oscar 2.1 on RH 7.3). I want to update the kernel to 2.4.20-20.7smp. I don't know the proper steps to update the computing nodes. Thank you in advance for your help.
Regards, Julia
