Updating kernel on iSCSI boot system

I have a DL360 which successfully boots RHEL4U4 off the SAN using the instructions in the HP document "HP iSCSI Boot for Linux User Guide". The only problem that I have is that the process uses a custom kickstart file to load the iSCSI drivers into the kernel during the initial OS installation. You're essentially stuck with the kernel as it exists then and you can't update it with any patches. Does anyone have a solution to this? THANKS!

Why do you think that you can't update your kernel after the initial installation? If the modules are provided with the right tools, you can buid the module for any kernel.


And also, please see:

Re: Updating kernel on iSCSI boot system

You will just need to ensure your iSCSI drivers are in your initrd image and in your new kernel.
