114 Installing Managed System Software on Supported Linux and VMware ESX
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:
1
Ensure that the prerequisites of DKS are met.
2 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 Instrumentation feature of Server Administrator requires the
OpenIPMI device driver that provides IPMI-based information and
functionality.
All supported Linux systems contain the required version of IPMI module in
the default kernel itself. You do not need to install the IPMI RPM. For more
information on supported systems, see the Dell Systems Software Support
Matrix available at Dell Support site at support.dell.com.
Degradation of Functionality When the Server Administrator
Instrumentation Service is Started
After Server Administrator is installed, the Server Administrator
Instrumentation Service will do a run-time check of the OpenIPMI device
driver whenever it is started. The Server Administrator Instrumentation
Service is started whenever you run either the srvadmin-services.sh start or
srvadmin-services.sh restart commands, or you restart the system (during
which the Server Administrator Instrumentation Service is started).
