Embodiment Construction

[0022] In the disclosed resetting method and monitoring device, if an abnormality occurs in the monitoring device, a software reset is performed with the data held in the volatile memory left as it is. Depending on the hardware of the monitoring device, there is a function of performing a hardware reset while leaving the data held in the volatile memory as it is, but a software reset is performed for hardware that does not have this function.

[0023] The volatile memory stores control information for controlling the main body of the computer monitored by the monitoring device, in addition to data including failure investigation data (or failure information) retained when a failure occurs. The control information used to control the main body of the computer includes, for example, management parameters such as various voltage values ​​and fan speeds. The monitoring device reads failure information from the hardware of the monitoring device at regular intervals, and determines ...

Abstract

A reset method performs a software reset in a state in which data stored in a volatile memory is retained, when an abnormality is generated in a monitoring apparatus. Depending on hardware of the monitoring apparatus, the hardware may include a function to perform a hardware reset in a state in which the data stored 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 that is 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 of the monitoring apparatus for every predetermined time, in order to perform a process to judge whether an abnormal value is reached.

Description

technical field [0001] The present invention relates to a reset method for resetting a monitoring device while preserving a hardware state as it is, and a monitoring device using the reset method. The present invention also relates to a computer program for causing a computer to execute the reset method and a computer-readable storage medium storing the computer program. Background technique [0002] If the main body of the computer is abnormal, a hardware reset is performed. A general hardware reset resets the entire system board including the core of a processor such as the CPU (Central Processing Unit) and peripheral processors such as a memory controller and a LAN (Local Area Network) controller. Each part is set to an initial state. Fault information such as traces (or action history) used for fault analysis are frequently changed, so they are kept in the volatile memory. However, if the volatile memory is reset to the initial state by Data held in volatile memory wi...
