Edit in the file /stand/system

When this is done, execute

mk_kernel
kmupdate

reboot your server

hey;

Primarily depends on your OS level. Check http://www.olearycomputers.com/ll/hpkernel.html for a checklist for 11.11 and below. 11.23 made kernel updates much easier.

Regardless which version, though, you can create a datafile of your kernel parms and values then loop through it with a simple inline loop:

11.11: Assumes you followed the directions in the checklist. ${system} is the /stand/build/system file.

cat ${file} | while read p v
do
kmtune -s ${p}=${v} -S ${system}
done

Follow the rest of the checklist for kmupdate/reboots

11.23:

cat ${file} | while read p v
do
kctune ${p}=${v}
done

Reboot if necessary.

HTH;
