Abstract

The invention discloses an information processing apparatus and an operation status monitoring method. The information processing apparatus includes a plurality of controller modules capable of performing communications with each other, and a memory included in each controller module to be stored with status information reflecting a status of an error occurring during the communications with other controller modules with respect to the controller module of a communication partner apparatus and / or the controller module of the self-apparatus, wherein When determining whether or not a fault occurs in a certain controller module in the plurality of controller modules, the controller module different from a determination target controller module determines, based on status information of the determination target controller module that is stored on the memories of two or more controller modules different from the determination target controller module, whether the fault occurs in the determination target controller module.

Description

technical field [0001] The present invention relates to an information processing apparatus including a plurality of controller modules capable of communicating with each other and an operation state monitoring method of monitoring the operating states of the plurality of controller modules capable of communicating with each other. Background technique [0002] Among information processing devices, there are some devices each including a plurality of controller modules capable of communicating with each other, wherein if a certain controller module fails, operation is continued by detaching this controller module from other parts. Such an information processing device is configured such that usually one module (controller module or status monitoring module) determines (determines) which component (controller module, circuit in the controller module, etc.) fails. However, in a device in which one module determines whether each component is malfunctioning, if this module malfu...
