摘要：
The present invention continues host access and holds data of a migration source volume as the latest data even when a fault occurs in any of a plurality of access paths.Upon receiving a first write command from a host computer via a first access path, the migration source controller writes first update data to the migration source volume and, upon receiving a second write command from the host computer via a second access path, the migration destination controller transfers second update data to the migration source controller via a storage path and, upon receiving the second update data from the migration destination controller, the migration source controller writes the second update data to the migration source volume.
