摘要： A storage apparatus includes a storage drive which writes and reads out a block of data with respect to a storage medium loaded on the storage apparatus, a processor which executes access control on a plurality of volumes assigned to the storage medium and a memory which stores a piece of management information that includes a piece of information indicating a usage frequency of each of the volumes. The processor executes a procedure including: determining a reallocation target volume from among a plurality of volumes assigned to the storage medium based on the management information, and moving the data of the reallocation target volume to a reallocation destination storage medium which is different from the storage medium.

摘要： A redundant system includes a redundant apparatus and a control unit that controls power supplied to the redundant apparatus. The redundant apparatus includes a state management unit that manages an operational state of the redundant apparatus, and a response unit that returns the operational state to the control unit. The control unit includes a first requesting unit that requests a redundant apparatus that operates as an operation system for the operational state information, a first determination unit that determines whether the response to the request is returned within a predetermined time, a second determination unit that determines whether the operational state is normal if the response is returned within the predetermined time, and a shutdown unit that shuts down the power supply to the redundant apparatus, if the second determination unit determines that the operational state is not normal.
