HPUX Kernel Configuration

1) Go to /stand/build

2) system_prep -v -s system

The system_prep script creates the system file /stand/build/system in your current directory.

3) Edit the /stand/build/system file to perform your task.

4) mk_kernel -s system : Build the kernel.

The mk_kernel command creates /stand/build/vmunix_test, a kernel ready for testing.

If you get this message when executing mk_kernel,
ERROR: Kernel is too large to boot.
Actual: 15605892 bytes
Limit: 13580288 bytes

eliminate optional subsystems or drivers and decrease the tunable parameters.

Move the old system file and kernel so if anything goes wrong, you still have a bootable kernel.

mv /stand/system /stand/system.prev
mv /stand/vmunix /stand/vmunix.prev

5) Move the new system file and new kernel into place, ready to be used when you reboot the system.

mv /stand/build/system /stand/system
mv /stand/build/vmunix_test /stand/vmunix

6) Reboot the server.
