duplicating kernel parameters

Ricky_4 — Sat, 14 Aug 2004 22:29:29 GMT

Hi All,

We would like to duplicate kernel parameters of our rp5430 to the new 5 rp5470 server. What I only know is compare rp5430 kernel parameters one by one then apply to rp5470 using SAM but it looks tedious from us. Please provide us procedure a faster way to duplicate this kernel parameters aside from what we know.

Thanks in advance.

If you check them all one-by-one, yes that would be tedious.

What I do is use /opt/ignite/bin/print_manifest to print a current manifest for a system. This includes any kernel parameters that have been changed from their default values. I then take that list from print_manifest and evaluate each one and decide what is appropriate for a new system.

Another possible way to get the same kernel parameters is to copy the kernel tunables section from the /stand/system file from one system to the other. You don't want to simply grab the entire /stand/system file and replace it on the new system, but you should be able to grab all of the tunables from /stand/system and copy them to the /stand/system file on the new boxes.

You can check the current kernel parameters using kmtune on both system. Then
use kmtune/kmsystem or manually change the /stand/system file
then run config -t /stand/system

and reboot.

this should take care of the differences.
