Installing Managed System Software on Supported Linux Operating Systems 89
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.
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
http://support.dell.com/support/edocs/software/omswrels/index.htm .
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).
Server Administrator installation blocks the installation of Server
Administrator packages if an appropriate version of the OpenIPMI device
driver is not currently installed on the system. However, it is still possible,
though not typical, that you can uninstall or replace a sufficient version of the
OpenIPMI device driver after Server Administrator has been installed. Server
Administrator cannot prevent this.
To account for a user uninstalling or replacing a sufficient version of the
OpenIPMI device driver after Server Administrator has been installed, the
Server Administrator Instrumentation Service checks the OpenIPMI device
driver version whenever it is started. If a sufficient version of the OpenIPMI
device driver is not found, the Server Administrator Instrumentation Service
will degrade itself so that it does not provide any of its IPMI-based
information or functionality. Primarily, this means that it will not provide any
probe data (for example, fans, temperatures, and voltage probe data).
