Abstract: According to this invention, a computer system has a host computer, a first storage subsystem providing a first volume, a second storage subsystem providing a second volume for storing a copy of data stored in the first volume. The computer system stores copy configuration information including correspondence between the first volume and the second volume. The management computer transmits the data erasure request to the first storage subsystem upon reception of a first data erasure request for erasing the first volume. The first storage subsystem stops a copying process of data stored in the first volume to the second volume, transmits a second data erasure request for erasing the second volume to the second storage subsystem, and erases the data stored in the first volume. Thus, in the case of erasing data stored in a storage area, corresponding data stored in a destination storage area is also erased so that security risks can be reduced.

Abstract: According to this invention, a computer system has a host computer, a first storage subsystem providing a first volume, a second storage subsystem providing a second volume for storing a copy of data stored in the first volume. The computer system stores copy configuration information including correspondence between the first volume and the second volume.

The first storage subsystem stops a copying process of data stored in the first volume to the second volume, transmits a second data erasure request for erasing the second volume to the second storage subsystem, and erases the data stored in the first volume. Thus, in the case of erasing data stored in a storage area, corresponding data stored in a destination storage area is also erased so that security risks can be reduced.

Abstract: A computer system comprises a storage subsystem, a host computer and a management computer, and stores catalogue information containing correspondence between a first volume for data reading or writing and a second volume for storing a copy of the data stored in the first volume. The management computer requests the storage subsystem to erase the data stored in the first volume upon reception of an erasure request of the data stored in the first volume. The storage subsystem erases the data stored in the first volume. The management computer specifies a second volume for storing the copy of the data stored in the first volume based on the catalogue information. The storage subsystem erases data stored in the specified second volume. Thus, security risks are reduced by erasing data regarding the data when the data stored in the volume is erased.

Abstract: The load of managing a storage system is lessened. In a storage system where multiple logical volumes are included in a logical volume group and a copy of the logical volume group is made in a pool area different from the one to which the logical volume group belongs, a management computer adds to the pool area capacity when the capacity of a pool area exceeds a predetermined threshold. When the pool area includes multiple logical volume groups, the management computer requests the storage system to create a pool area for each of the logical volume groups and to create the logical volume groups respectively for the created pool areas. When the pool area includes one logical volume group, the management computer requests the storage system to make the capacity of the pool area coincide with the capacity of a pool area to which the logical volume group is copied.
