Patent ID: 7917664

Claim:
A storage apparatus having a plurality of storage units for storing data, comprising: a plurality of detecting modules that each detect status information indicative of the operation environment, including abnormal states of at least one of voltage value information, a number of fan rotations, and a temperature related to said storage apparatus; a controlling module configured to access said stored data in said plurality of storage units, said controlling module performing processing in accordance with said status information; and a relaying module connected to said plurality of detecting modules and said controlling module and configured to relay said stored data between said controlling module and said plurality of storage units and to relay said status information between said controlling module and said plurality of detecting modules, said relaying module being further configured to store the status information detected by said plurality of detecting modules, to set and store, within the relaying module, flag information indicating whether the relaying module has already transmitted a notification, which indicates that the status information has changed to at least one of the abnormal states, to the controller module, to transmit said stored status information to the controlling module when the flag information indicates that the relaying module has not yet transmitted the notification to the controlling module and subsequently set the flag information to indicate that the notification has been sent to the controlling module, and to not transmit said stored status information to the controlling module when the flag information indicates that the relaying module has already transmitted the notification to the controlling module.
