Abstract
Timing at which a rotation of a physical disk can stop is taken to more appropriately stop the rotation of the physical disk. A management device for managing a storage device and a server includes a first recording part in which an identification number of a logic volume and a rotational state of the physical disk are recorded, a second recording part in which an operating state of the server and an identification number of the logic volume to be accessed by the server are recorded, an updating part for changing the operating state of the server recorded in the second recording part when the operating state of the server is changed, an extracting part for extracting an operating state of another server to access another logic volume of the physical disk having the logic volume to be accessed by the server set from the second recording part based on the identification number of the logic volume to be accessed by the server recorded on the first recording part, and an instructing part for giving an instruction to the storage device for changing the rotation state of the physical disk depending on the operating state after the server is changed and the operating state of the other server.
