Abstract: A method of automatic configuration of field replaceable units in a system includes steps of accessing configuration management system (CMS) class information from a field replaceable unit (FRU) and using the accessed information for deriving an initial configuration for the FRU. The FRU can contain information defining one or more configuration management system classes for the FRU. One or more management classes may be identified for managing one or more resources for the FRU. The CMS class information is then be used to derive the initial configuration information for the FRU for managing the device(s) of that FRU. The CMS class information can be held in non-volatile memory in the FRU. This information can be read on inserting the FRU into the system and can be used to establish the initial configuration prior to full integration of the FRU into the system.

Abstract: The health of a process is monitored in a computer system by a process monitor. The monitored process (a configuration management system daemon (CMSD)) is not a child of the process monitor. The process monitor uniquely determines the identity of a monitored process and verifies the correct operation of the monitored process. In the absence of verification of the correct operation of the monitored process, the monitored process is caused to initiate. On successful initiation of the monitored process, the monitored process is uniquely identified to the system and is detached from the process monitor. Each monitored process is arranged to write, on initiation, its unique process identification information (PID) to a file, which file is then accessed by the process monitor to identify the process monitor. The process monitor can interrogate the operating system to verify correct operation of the CMSD.
