HP-UX 11i Version 2 Release Notes (October 2003)

General System Administration

HP-UX Kernel Configuration

Chapter 4

In HP-UX 11i v2, the Kernel Configuration (KC) commands have been replaced by a new

set of commands. The config, kmadmin, kminstall, kmmodreg, kmsystem, and kmupdate

commands have been removed. The kmtune, kmpath, and mk_kernel commands have

only limited transitional support and will be removed in a future release. The new KC

commands are kconfig, kcmodule, kctune, kclog, and kcpath.

In addition to these command changes, there are changes to the location of kernels and

related files on disk; to the manner in which a kernel configuration is chosen at boot

time; and to the manner in which the system automatically maintains a backup kernel

configuration.

For more information, see the documentation listed below.

Impact

With the new KC commands, the customer has simpler, more reliable, and more efficient

management of HP-UX kernel configurations. With the new KC commands, many

configuration changes that required a kernel rebuild and system reboot can now be made

without them. Even when a kernel rebuild or system reboot is still required, no

compilations of kernel code are needed. The new KC commands share a consistent user

interface and management model.

Customers who are used to using the removed commands, listed above, will need to use

the appropriate new KC command. System administrators will need to be aware of the

changes in kernel location, boot-time selection, and automatic backup creation.

Compatibility

The HP Apache-based Web Server must be installed for kcweb to work. HP Apache does

not need to be running on its default port 80. The kcweb tool can be used with a locally

installed copy of Mozilla or Netscape. The Mozilla, Netscape, and Microsoft Internet

Explorer Web browsers can also be used from any type of remote system.

NOTE For the kcweb tool (GUI mode) to run, cookies must be enabled in your browser (Mozilla

or Internet Explorer).

Scripts or applications using the commands being removed will have to be changed. (For

kmtune and kmpath, which are the most commonly used scripts, compatibility interfaces

have been provided to ease the transition.)

Scripts or applications that hard-code the location of the kernel should be changed.

Performance

There will be no noticeable increase or decrease in response time for Kernel

Configuration tasks.
