PROBLEM TO BE SOLVED: To easily and efficiently enable the execution of a test of a storage device even in the case that the configuration of an arithmetic processing unit, the configuration of the storage device, or an interface between the arithmetic processing unit and the storage device is complicated or the like in an information processing device including the arithmetic processing unit and the storage device.SOLUTION: The information processing device includes the arithmetic processing unit for outputting an access request, the storage device for storing data, a storage control device for receiving an access request to the data stored in the storage device from the arithmetic processing unit, transferring the received access request to the storage device, and acquiring a response to the access request from the storage device, and a diagnostic control device for transmitting the access request to the storage device to the storage control device instead of the access request to the storage device from the arithmetic processing unit and acquiring a response from the storage device through the storage control device.SELECTED DRAWING: Figure 2 【課題】演算処理装置と記憶装置とを含む情報処理装置において、演算処理装置の構成、記憶装置の構成、あるいは演算処理装置と記憶装置とのインターフェースが複雑化した場合等においても、簡易かつ効率的に記憶装置の試験を実施できるようにする。【解決手段】情報処理装置は、アクセス要求を出力する演算処理装置と、データを記憶する記憶装置と、演算処理装置から記憶装置が記憶するデータへのアクセス要求を受け付け、受け付けたアクセス要求を記憶装置に転送し、アクセス要求に対する記憶装置からの応答を取得する記憶制御装置と、演算処理装置から記憶装置へのアクセス要求に代わって、記憶装置へのアクセス要求を記憶制御装置に送出させるとともに記憶制御装置を介して記憶装置からの応答を取得する診断制御装置と、を備える。【選択図】図２
