Changes to Kernel

[Carme Torca]

Hi,

I need to do two changes to the kernel, I have to change one static parameter and I have to install some patches too than reboot the system.
Is possible to do this with only one reboot?

Thanks a lot of,
Carmen.

Hi Carmen,

You may try this in a TEST server (since I don't know the results...) on SAM (Kernel Configuration -> Configurable Parameters -> [Modify the parameters] -> File -> Exit -> Defer Kernel Creation Until Later -> Software Management -> Install Software to Local Host -> ...

It's possible... if you have a support contract pull up itrc doc id KBRC00012410

I hadn't authored many docs, but I added this one when I was at HP :)

If you don't have access to it, look at the swagent man page... As part of the swagent's defaults there is a setting for "system_prep_cmd". You can write a script that will do system_prep followed by a kmtune to tune your kernel parms... It will be executed as part of the swinstall session.

I don't know of many people that would do it this way. Usually feel it's best to make one change at a time (ie/ (1)patch install then (2) specific kernel changes)

If you can't view the doc and decide to push forward and need help w/ the one time patch + kernel parm change, post here if you need help w/ setting up /var/adm/sw/defaults file and temp sys_prep script. The man page explains it too... (man swagent, look for system_file_path=/stand/system and system_prep_cmd=/usr/lbin/sysadm/system_prep)
