Transition from Previous HP-UX Releases

Experienced administrators of releases prior to HP-UX 11i v2 will find some aspects of the kernel configuration mechanisms to be unfamiliar. However, many of the underlying concepts are unchanged. The tables in this section give information to help administrators to make the transition.

Table 10-18 Kernel Configuration Methodology

HP-UX 11i Version 1 and Before	HP-UX 11i Version 2 and After
Use SAM to configure the kernel.	Use HP SMH to configure the kernel.
Look at `/stand/system` to see the current configuration.	Same. ^[1]
Run an unsupported command to make sure `/stand/system` is up to date.	Not needed. `/stand/system` is automatically kept up to date. ^[1]
Make configuration changes by editing `/stand/system` and running mk_kernel.	Same. Changes will be applied to the running system (no reboot), if possible. ^[1]
Make configuration changes by running kmtune or kmsystem, then running mk_kernel.	Make the changes with kctune or kcmodule (no mk_kernel), or edit /stand/system manually and then run mk_kernel. ^[1] ^[2] ^[3]
Make configuration changes by editing `/stand/system` and running config.	Use mk_kernel instead. ^[1]
Manage DLKMs with the kminstall, kmsystem, kmmodreg, kmadmin, kmupdate, and config commands.	Manage DLKMs using kcmodule. ^[2]
View or change tunables using kmtune. ^[4]	Use kctune instead. ^[3]
^[1]See “Managing Configurations with System Files”. ^[2]See “Managing Kernel Modules with kcmodule”. ^[3]See “Managing Kernel Tunable Parameters with kctune”. ^[4]HP-UX 11i v2 contained a compatibility stub for kmtune. It was removed in HP-UX 11i v3.

Table 10-20 Kernel Configuration Files and Directories

HP-UX 11i Version 1 and Before	HP-UX 11i Version 2 and After
Currently running kernel: `/stand/vmunix`	`/stand/vmunix`
Backup kernel`: /stand/vmunix.prev`	Backup configuration: `backup` ^[1]
Test kernel: `/stand/build/vmunix_test` (default output of mk_kernel)	Test configuration: `hpux_test` ^[2]
Primary system file: `/stand/system`	`/stand/system` ^[2]
Module system files: `/stand/system.d/*`	No longer used. The data are now in the primary system file, `/stand/system`. ^[2]
Master files: `/usr/conf/master.d/*`	No longer used. The data are embedded into the kernel code, and available through the kcmodule and kctune commands. ^[3] ^[4]
