• Several commands are obsolete in HP-UX 11i v2:
— config—configure and build an HP-UX system.
— kmadmin—kernel module administration.
— kminstall—add, delete, update the installation of a kernel module.
— kmmodreg—register or unregister loadable kernel modules with the running kernel.
— kmsystem—set, query planned configuration attributes of kernel modules.
— kmupdate—update default kernel, or update specified kernel modules.
— Deprecated Commands
— kmtune—this now calls kctune.
— kmpath—this now calls kcpath.
— mk_kernel—this is now a script that calls kconfig.

• Several new commands are added in HP-UX 11i v2:
— kconfig—used for managing kernel configurations.
— kctune—used for managing tunable kernel tunables (tunables).
— kcmodule—used for managing the states of kernel modules
— kclog—used for viewing the contents of the kernel configuration log.
— kcpath—used by scripts to determine the path of the running kernel.
• Several tunables have been obsoleted and new ones added

— Obsolete Tunables
— shmem
— sema
— mesg
— maxusers
