Installing Managed System Software on Supported Linux Operating Systems 143

Forcing Dynamic Kernel Support on Red Hat Enterprise Linux Update Releases

After the installation of Server Administrator, perform the following steps to

force DKS to be used on Red Hat Enterprise Linux Update releases to build

device drivers for the running kernel, if needed, so that they do not taint the

kernel:

Ensure that the prerequisites of DKS are met.

Execute the following command:

/etc/init.d/instsvcdrv restart-forcekernelmatch

This command will first stop the Server Administrator device drivers. It will

then search for precompiled device drivers to load, by checking for precompiled

device drivers built for a kernel whose name is an exact match as the name of

the running kernel. If it fails to find an exact match, it will use DKS to build

device drivers for the running kernel. Finally, the command will restart the

Server Administrator device drivers.

NOTE: The system must be rebooted to clear the kernel "tainted" status.

OpenIPMI Device Driver

The Server Administrator Instrumentation Service of Server Administrator

requires the OpenIPMI device driver in order to provide IPMI-based

information and functionality. It also requires a minimum version of the

OpenIPMI device driver. The minimum version required is defined based on the

Red Hat Enterprise Linux or SUSE Linux Enterprise Server operating system.

This requirement is checked and enforced by Server Administrator at three

instances. Two of the instances are during installation, while the third is a

run-time step. The instances are:

• During custom installation of Server Administrator using the

srvadmin-

install.sh

shell script.

• During installation of Server Administrator using RPM.

• At run-time when the Server Administrator Instrumentation Service is

started.

NOTE: SUSE Linux Enterprise Server (version 10) contains the required version of

IPMI module in the default kernel itself. You do not need to install the IPMI RPM.
