摘要:
A file management sub-system executes file migration without causing an unintended drop in the response time or the like. When a management computer issues a file migration direction, a file storage apparatus notifies client computer associated with a migration target file that file migration is scheduled. When postponement or suspension of file migration is requested by the client computer, the file migration is postponed or suspended.
