A storage apparatus according to the present invention can store information related to a power supply abnormality after shutting down the principal functions of a data processing board when a power supply abnormality occurs in a data processing board. A power supply controller of a data processing board mounted in the storage apparatus monitors the operational status of DC/DC power supplies mounted to the data processing board, on the basis of detection signals from a voltage detection circuit. When a power supply abnormality is detected, the power supply controller immediately shuts down the operation of all the DC/DC power supplies. Shutting down the DC/DC power supplies also shuts down the principal functionality of the data processing board. Then, after storing information related to the power supply abnormality in memory, the power supply controller shuts down the auxiliary power supply. The information stored in memory can be transmitted to a management apparatus by way of an intermediary apparatus, which is another data processing board or the like.
