Abstract

The storage control device of the present invention uses a temporary volume to move data rapidly between volume groups. The storage control device forms a plurality of volume groups by grouping volumes of the same performance. At least one or more temporary volumes are each pre-provided in the respective volume groups. The control section calculates and manages the priority levels of the respective data. The data with the highest priority level in the lower volume group are copied beforehand to the temporary volume in the upper volume group at a time when the data are not being accessed by the host. As a result, data can be moved rapidly when data migration is executed and so forth.
