Abstract:
Provided is a computer system including: a host computer; a first storage system connected to the host computer; and a second storage system connected to the first storage system; in which the first storage system sets a first logical volume recognized by the host computer as a logical storage area; the first logical volume includes a plurality of first storage areas; a first real storage area on the first disk drive is allocated to at least one of the first storage areas. In the computer system, the second storage system sets a second logical volume corresponding to the first logical volume, and the first storage system transmits data stored in the first storage area allocated to the first storage area to the second storage system when the first real storage area is allocated to the first storage area.
