94 Installing Managed System Software on Supported Linux Operating Systems
To use DKS, identify which kernel is running on the managed system, and
check the DKS prerequisites.
Determining the Running Kernel
1 Log in as root .
2 Type the following command at a console and press <Enter>:
uname -r
The system displays a message identifying the running kernel.
Dynamic Kernel Support Prerequisites
For managed system software to use DKS, the following dependencies must
be met before starting Server Administrator.
• The running kernel must have loadable module support enabled.
• The source for building kernel modules for the running kernel must be
available from
/lib/modules/`uname –r`/build . On systems running SUSE
Linux Enterprise Server, the
kernel-source RPM provides the necessary
kernel source. On systems running Red Hat Enterprise Linux, the
kernel -
devel
RPMs provide the necessary kernel source for building kernel
modules.
• The GNU make utility must be installed. The
make RPM provides this
utility.
• The GNU C compiler (gcc) must be installed. The
gcc RPM provides this
compiler.
• The GNU linker (ld) must be installed. The
binutils RPM provides this
linker.
When these prerequisites have been met, DKS automatically builds a device
driver when needed during Server Administrator startup.
Using Dynamic Kernel Support After Server Administrator Installation
To enable Server Administrator to support a kernel that is not supported by
a precompiled device driver and is loaded after Server Administrator has been
installed, perform the following steps: Ensure that the DKS prerequisites are
met on the system to be managed and boot the new kernel on the system.
