Abstract
A storage control device includes a first storage device and a processor. The first storage device stores management information used for managing a variable area of storage regions of a second storage device in a storage apparatus. Each storage region is allocated to a main area or a spare area. The variable area includes storage regions allocated to the spare area and allocatable to the main area. The processor acquires, from the storage apparatus, information on numbers of times of Read processing on the second storage device and numbers of times of Write processing on the second storage device, and notifies the storage apparatus, when a number of times of Read processing on the second storage device within a predetermined time period is larger than a predetermined threshold, of a request for allocating a first portion of the variable area to the main area on basis of the management information.
