Overview of HP SMH for Kernel Configuration
You can configure and manage the kernel without remembering the syntax of the kernel
configuration commands or the exact names of modules and tunables by using HP SMH, the
web- and text-based HP-UX kernel configuration tool to configure and manage the kernel of
your system. HP SMH has the following features:
• Web-based and text-based interfaces.
• Kernel tunable management: monitor and modify.
• Alarm management: add, modify and remove.
• Kernel module state management: modify.
• Access to manpages for tunables.
• Command preview – When a tunable, module or alarm is modified, you can use the
command preview feature by choosing the Preview button. This will show the kernel
configuration command invocation that will perform the requested task.
You can access Kernel Configuration in any of the following ways:
• From the command line with the kcweb -t command.
• With a web browser through the Kernel Configuration area of HP-UX System
Management Homepage.
By default, the kcweb command invokes the Mozilla web browser. If you want to invoke kcweb
with any other browser, set the BROWSER environment variable to the path name of the
browser you wish to use. For more details, see the kcweb(1M) manpage.
Interpreting Module Information
Looking at the sample output in “Getting Information About Modules” below, you can see that
each module has a name and a textual description. Each module also has a version, which
typically looks like 1.0.
A kernel configuration can only use one version of any given module. However, multiple
versions may be listed if, for example, your currently running system is using a different version
of a module from the one that will be used at next boot. Version numbers are normally omitted
from the short listing, but will be included if there’s more than one version of a module.
