11) Updating Kernel in HP-UX 11i :

#cd /stand/build
#/usr/lbin/sysadm/system_prep -s system

This extracts the kernel file from currently running system.

#mk_kernel -s system

Makes new kernel in /stand/build directory called vmunix_test.
DLKM files are produced as /dlkm.vmunix.prev

At this point, the new kernel exists in the /stand/build directory.

It is recommended that you rename the existing kernel

#mv /stand/system /stand/system.prev

Now update the new kernel with :
#kmupdate /stand/build/vmunix_test

Kmupdate will automatically create backup copies of
/stand/vmunix and /stand/dlkm

as vmunix.prev and dlkm.prev under /stand

You can shutdown and boot from new kernel.
cd /; shutdown -r 0

Shuts the system so it comes with new kernel.

12) sam – starts the menu driven system Administration Manager.

Extras:
*) /stand : This contains kernel configuration and binary file that are required to
bring up a system. The important files in this dir is system, cmunix and dlkm files.

*) Default File System used in HP-UX 11i is Journal File System(JFS).
