GOAL:
How to manually set kernel parameters on HP-UX.
FACT(s) (Environment):
HP-UX
FIX:
The easiest way to configure kernel parameters on HP-UX is to use HP's GUI system administration utility called "SAM".
However, if you'd like to configure the HP-UX kernel parameters manually (at the command line), follow the steps outlined below:
1) Be sure you're in the the build environment directory.
cd /stand/build
2) Next, create a kernel parameter file called "system.mod", which can be edited by extracting the parameters from the currently running system.
/usr/lbin/sysadm/system_prep -s system.mod
3) Open the kernel parameter file (system.mod) with any ASCII text editor and specify (or modify) the kernel parameters you want to change.

4) Next, build the new kernel.
/usr/sbin/mk_kernel -s ./system.mod
This creates the file: /stand/build/vmunix_test.
5) Be sure to save the original system and vmunix files for backup purposes.
mv /stand/system /stand/system.copy
mv /stand/vmunix /stand/vmunix.copy
This will ensure that you can revert back to a bootable kernel, assuming the manual changes don't work.
6) Then, move the system.mod and vmunix_test files to the /stand directory.
mv system.mod /stand/system
mv vmunix_test /stand/vmunix
7) Finally, reboot the system and test the new kernel settings.
