Abstract
In a storage system, when a recovered error occurred upon access to a storage apparatus, a data redundancy determination unit determines whether data to be accessed has redundancy. When the data is determined to have no redundancy, an anomaly-occurring portion determination unit determines that the storage apparatus is not an anomaly-occurring portion and at the same time, an error history determination unit determines whether a recovered error occurred at the time of the past access to the storage apparatus other than that of the access destination. The anomaly-occurring portion determination unit determines whether a common transmission path is the anomaly-occurring portion based on the determination result of the error history determination unit.
