DLKM Tools
There are a number of HP-UX commands known collectively as the
kernel configuration tool set for installing, configuring, and managing
DLKM modules. These commands are presented with descriptions and
applicable command line options in this section.
Why You Should Use the Kernel Configuration Tools Although
the HP-UX static kernel environment has not changed, it is affected by
the configuration of kernel modules within the DLKM infrastructure.
Specifically, DLKM requires that a kernel module have its own master
and system files, and contain a Module Wrapper.
To the overall HP-UX kernel configuration environment this means:
1. The configurable module information is distributed among several
files:
• traditional modules use the /stand/system file
• modularly packaged modules use their own module-specific
system file
2. The kernel structure is extended:
• static kernel executable file /stand/vmunix
• associated DLKM kernel components under/stand/dlkm:
— kernel symbol table
— dynamic loadable modules
Because of the effects that the DLKM infrastructure has on the overall
kernel configuration environment, it is best to configure any type of
kernel module using the tools described in this section.
Avoid editing the system file, or replacing the kernel file manually, as
doing so increases the chance of introducing configuration errors.
For more detailed information regarding the master and system files,
refer to the master (4) manpage and the config (1M) manpages.
