摘要
Exemplary embodiments provide data volume migration with migration log confirmation in which the same data volume identifier is used beyond migration for a data volume. In one embodiment, data is migrated to or from a data volume in a data storage area of a storage apparatus. The data being migrated is identified by a data volume identifier which remains unchanged after migration. The same data volume identifier is used in both the source data volume and the destination data volume. The storage apparatus stores migration log information of the data volume. The migration log information includes the data volume identifier, a source name of the source data volume of the data being migrated, a destination name of the destination data volume of the data being migrated, and log information on any prior migration of the data being migrated.
