Configuring an HP-UX Kernel
Kernel management in HP-UX 11i Version 2 is done with a set of kernel configuration commands or through the web-based kcweb tool. This chapter covers the kernel-related commands, gives some examples of using the commands to modify and build kernels, and gives an overview of kcweb.
Most applications require that you to modify your kernel in some way. You may need to create a new HP-UX kernel to add device drivers or subsystems, tune the kernel to get improved performance, alter configurable parameters, or change the dump and swap devices. If you update or modify a dynamic element of your kernel, as shown in an example in this chapter, a reboot is not required. Updating or modifying a static element requires a reboot and may also require some additional steps, which a later example shows.
This chapter covers the following topics:
- Overview, examples, and running kernel-related commands: kcmodule, kctune, kconfig, kclog, kcalarm, kcusage, and kcmod
- A flowchart showing a typical kernel rebuild
- Example of using the entries in the flowchart to rebuild a kernel
- Example of booting a saved kernel configuration
- The system file and making multiple kernel changes using it
- Overview of the Web-based kernel tool kcweb
