Server Administrator Version 7.4 Installation Guide

After Server Administrator is installed, the Server Administrator Instrumentation Service performs 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 when 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 degrades itself so that it does not provide any of the IPMI-based information or functionality. Primarily, this means that it does not provide any probe data (for example, fans, temperatures, and voltage probe data.)
