ABSTRACT:
A method for migrating a block of data within a storage system includes migrating first data stored in a first storage volume of a first storage subsystem to a second storage volume in a second storage subsystem. The first data is a block of data that is presented to a host so that the first data may be accessed by the host. First setting information relating to the first data is copied from a first setting volume to a second setting volume. The first and second setting volumes are provided in the first and second storage subsystems, respectively. The second storage volume is presented to the host, so that the host may access the first data stored in the second storage volume via a communication network.
