MANAGEMENT SYSTEM OF INFORMATION MEMORY SYSTEM AND MANAGEMENT METHOD THEREOF

摘要

Management method refers to position management information indicating an installation position of each of storage apparatuses. Positions of a first storage apparatus including a first volume and a second storage apparatus including a second volume composing a copy pair with the first volume are specified from the position management information. A positional relationship between the first and the second storage apparatuses before data migration is determined. If the second volume is not to be migrated, a condition of a positional relationship after the data migration to be satisfied between a migration destination storage apparatus of data of the first volume and the second storage apparatus is determined. Storage apparatus which satisfies at least the condition of the positional relationship after the data migration is selected from the storage apparatuses as the destination storage apparatus.
