Abstract: A reset method performs a software reset in a state in which data in a volatile memory is retained, when an abnormality is generated in a monitoring apparatus. Hardware of the monitoring apparatus may include a function to perform a hardware reset in a state in which the data in the volatile memory is retained, but the software reset is performed with respect to the hardware that does not include such a hardware reset function. The volatile memory may store control information for controlling a host computer monitored by the monitoring apparatus, in addition to data including fault check materials to be retained when the fault is generated. The monitoring apparatus may read the fault information from the hardware to judge whether an abnormal value is reached.

Abstract: A system monitoring device retains hardware state information of a computer system and OS software state information of a hardware control instruction given by OS software and monitors and controls the entire computer system. When state change of the hardware state information and OS software state information is recognized, save information is stored in a non-volatile memory. When re-activation accompanying active replacement of the system monitoring device, which has failed, is recognized, the save information is read from the non-volatile memory, and the corresponding hardware state information and OS software state information before device failure is restored. The operating hardware is recognized according to save information, and the hardware state information generated for the recognized hardware during active replacement is restored.

Abstract: An information processing apparatus is provided that executes a process sequence stored in a sequence table, based on a sequence code created for each process in the process sequence. The sequence code includes a process type that specifies a sequence table, a control target that specifies a control target, and a process number that specifies one particular process in the specified process sequence.
