Installing Managed System Software on Supported Linux Operating Systems 99
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. If it is not one of those listed in the managed
system software readme file, then the managed system software may need to use DKS to support it.
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 Red Hat Enterprise Linux (version 3) and SUSE
Linux Enterprise Server (version 9 and 10), the
kernel-source RPM provides the necessary kernel
source. On systems running Red Hat Enterprise Linux (version 4), 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 will automatically build a device driver when needed
during Server Administrator startup.
NOTE: Unsupported kernels are kernels that are not supported by a precompiled device driver. If you are running
a supported kernel, see "Installing and Upgrading Managed System Software."
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:
1
Ensure that the DKS prerequisites are met on the system to be managed.
2 Boot the new kernel on the system.
Server Administrator builds a device driver for the kernel running on the system the first time that Server
Administrator starts after the kernel is loaded. By default, Server Administrator starts during system startup.
