Installing Managed System Software on Supported Linux Operating Systems 131

Copy any
dcdbas.*
or
dell_rbu.*
files in the
/lib/modules/
<kernel>
/
kernel/drivers/firmware
directory
on system A to
the
/var/omsa/dks/
<kernel>
directory on system B, where
<kernel>
is the
kernel name returned by typing
uname -r
in step 3.
NOTE: The /lib/modules/<kernel>/kernel/drivers/firmware directory may
contain one or more of the following files: dcdbas.* or dell_rbu.*
NOTE: You might have to create the /var/omsa/dks/<kernel> directory on
system B. For example, if the kernel name is 1.2.3-4smp, you can create the
directory by typing:
mkdir -p /var/omsa/dks/1.2.3-4smp
5
Start Server Administrator on system B.
Server Administrator detects that the device driver you copied to the
/var/omsa/dks/
<kernel>
directory supports the running kernel and uses
that device driver.
NOTE: You can also use this procedure when upgrading Server Administrator
if the new version of Server Administrator does not support the running kernel
with a precompiled device driver.
NOTE: When you have uninstalled Server Administrator from system B, the
/var/omsa/dks/
<kernel>/*. files that you copied to system B are not removed.
You must remove the files if they are no longer needed.
Forcing Dynamic Kernel Support on Red Hat Enterprise Linux Update Releases
When Kernel is Tainted
Server Administrator provides precompiled device drivers for the "Gold" releases
of supported Red Hat Enterprise Linux operating systems. Red Hat Enterprise
Linux supports loading device drivers built for the "Gold" release, on the Update
releases. This means Server Administrator does not have to ship precompiled
device drivers for every Red Hat Enterprise Linux Update release and users are
not forced to use DKS in order to run Server Administrator on every system that
is running a Red Hat Enterprise Linux Update release. However, loading a device
driver built for the "Gold" release of Red Hat Enterprise Linux (version 4) on an
Update release may taint the kernel. If the kernel on a system running a Red Hat
Enterprise Linux (version 4) Update release has been tainted by this device
driver load process, Server Administrator’s init script command
restart-forcekernelmatch can be used to force DKS to be used in this situation.
DKS will build device drivers that do not taint the running kernel.
