NOTE This section applies to releases of HP-UX starting with 11i version 2. See
“Reconfiguring the Kernel (Prior to HP-UX 11i Version 2)” on page 282
for the procedures for releases prior to 11i version 2.
Introduction
With each successive release of HP-UX, system administrators have
increasing ability to make changes to the configuration of the HP-UX
kernel without experiencing costly and inconvenient downtime.
Innovations such as Dynamic Kernel Tunables and Dynamically
Loadable Kernel Modules allow critical maintenance tasks to be
performed without sacrificing application availability.
With these innovations comes the need for a simpler and more
comprehensive mechanism to manage kernel configurations. HP-UX 11i
version 2 introduces a new suite of kernel configuration management
commands and a new web-based graphical interface that provide unified
kernel configuration management. This section describes the use of these
new tools. It is intended for use by HP-UX system administrators.
Kernel Configuration Features
The new suite of kernel configuration tools provides several key features
for system administrators:
• All kernel configuration tasks can be performed in a single graphical
interface.
• All kernel configuration tasks can also be performed with a cohesive
set of commands with the same user interface and same behavior.
• Kernel configurations can be saved and restored, and moved between
systems.
• Administrators can save any number of kernel configurations, and
can switch between them at will — often without a reboot.
