transfer kernel parameters to another box

Kim Kendall — Fri, 13 Sep 2002 00:07:34 GMT

Looking to transfer all the kernel parameters from one machine to another... Is there a config file I can just move and rebuild from?

You MIGHT be able to just move /stand/system and rebuild the kernel, but I don't know that I'd necessarily want to try that.

What I would do, is just get a listing of the configurable kernel parms from one machine, go into SAM on the second machine, and make the changes as appropriate. Then let it rebuild your kernel and reboot.

r the boes of same Hardware / revisions / OS same configuration . u can move /stand/system file or else !!!! this will cause a PANIC !!!!. Best way is to note down the parameters & do the changes at the other boxes

Actually... It will be the same machine... After it's rebuilt, I just wanted to apply all of the previous mods and build another kernel (was hoping NOT to have to go down that entire list one by one just to change a few parameters)

The only real difference will be the distro I use. Still 11.0, but will be coming off brand new distribution CD's.

All H/W and config will be the same...

Kim,

For what it's worth, I just print out or copy /stand/system and then go through SAM to re-implement the kernel modifications manually.

Hi Kim,

The steps involved are

1.) # cd /stand/build
2.) # /usr/lbin/sysadm/system_prep -v -s system

3.) # /usr/sbin/mk_kernel -s ./system

4.) # mv /stand/system /stand/system.prev #new for dynamically linked modules at 11.0

5.) # mv /stand/build/system /stand/system

6.) # kmupdate # kmupdate automates moving the kernel files into the proper directory

7.) # shutdown -ry 0

Do the first two steps on node1 and then copy the system file to node2:/stand/build and then perform the remoaining steps on node2. This will duplicate the kernel parameters on node1 to node2.

Otherwise take a copy of kernel parametes on node1 "kmtune -S /stnad/system >/tmp/kernel_para_node1" and then moedify the kernel parameters on node2 manually. I hope the hardware is same.

Hope this helps.

in case you want to roll-out a kernel parameter set to more than one box I'd recommend to build a software depot for that task- see USDUXKBRC00008416 (a copy of this doc is given in http://forums.itrc.hp.com/cm/QuestionAnswer/1,,0x72134b3ef09fd611abdb0090277a778c,00.html)
