摘要: In a storage system, when power supply to HDDs is instantaneously interrupted, a spin up controller of a magnetic disk apparatus spins up the HDDs. On the other hand, based on a response for an access to the HDDs in the magnetic disk apparatus, when detecting that the HDDs as an access destination are spun down, a spin up controller of a control apparatus spins up the HDDs. When a certain number of the HDDs or more are spun down, a separate controller does not permit the magnetic disk apparatus to be used for a given length of time. While the magnetic disk apparatus is not permitted to be used, the HDDs are spun up by using the spin up controller of the magnetic disk apparatus.
