How to build a kernel in HP-UX before version 11i v2 (11.23)?

petulia3478

Building a kernel before HP-UX 11i v2. Always use the commands
to the build the kernel, NEVER edit the files manually

# cd /stand/build

Prepare a system file for a new kernel

# /usr/lbin/sysadm/system_prep -v -s system
NOTE: Dynamic tunable values (if applicable) have been added to
"system".
NOTE: The template file has been extracted from "/stand/vmunix"
It has been placed in "system" where it will be used
to build a new kernel.

View kernel modules that were selected to build the next kernel

# /usr/sbin/kmsystem -S /stand/build/system

Add additional kernel modules to the system file using

# /usr/sbin/kmsystem -S /stand/build/system -c Y driver-name

Build/make the new kernel

# /usr/sbin/mk_kernel -s /stand/build/system

This will create a kernel ready for testing /stand/build/vmunix_test
Use the kmupdate command to set the flag for booting using the kernel

# /usr/sbin/kmupdate

Inform users of a reboot or schedule it

Then just reboot or reboot and interrupt and power of system to add
new devices, then bring the system up

Depending on what you are doing either use:

# /usr/sbin/shutdown -r

If you are not attaching hardware or:

# /usr/sbin/shutdown -h

If you need to power of the system and associated devices
and then attach new hardware

NOTE: If the system fails to boot from the new kernel you have
a backup kernel /stand/vmunix.prev to boot from
