Installation manual

Installing Managed System Software on Supported Linux and VMware ESX 73

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 step: Ensure that the DKS prerequisites are

met on the managed system and boot the new kernel on the system.

Server Administrator builds a device driver for the kernel running on the

system the first time Server Administrator starts after the kernel is loaded. By

default, Server Administrator starts during system startup.

Copying a Dynamically Built Device Driver to Systems Running the Same Kernel

When the Server Administrator dynamically builds a device driver for the

running kernel, it installs the device driver in the

/lib/modules/

/kernel/drivers/firmware directory, where

the kernel name (returned by typing uname -r). If you have a system

running the same kernel for which a device driver was built, you can copy the

newly built device driver to the /var/omsa/dks/

directory on the other

system for use by the Server Administrator. This allows the Server

Administrator to use DKS on multiple systems without having to install the

kernel source on every system.
