A management system manages a computer system having multiple storage apparatuses, which provide a virtual volume to a host. The computer system includes a pool, and the storage apparatus allocates a physical page in the pool to a write destination when writing to the virtual volume. The management system stores logical volume management information for managing a corresponding relationship between a storage apparatus in which a logical volume resides and a physical page forming the logical volume, and virtual volume management information for managing the corresponding relationship between a virtual segment in a virtual volume and a page allocated to the virtual segment, and based on the logical volume management information and the virtual volume management information identifies a first page migration, which is affected in a case where either a determination-target storage apparatus is stopped or a first storage area is blocked, and displays the first page migration information. |
