Abstract: A storage system comprises multiple storage apparatuses and the multiple storage apparatuses provide a host system with a virtual volume in which multiple logical volumes are virtualized into one. When a first storage apparatus has detected a first event, the first storage apparatus changes the status of a first resource. Thereafter, the first storage apparatus sends a notice of the status change with respect to a first logical volume to a second storage apparatus comprising a second logical volume which is the basis of a virtual volume associated with the first logical volume, when the first storage apparatus has detected a second event which signifies that the host system is informed, in the future, of the status of the first resource. The second storage apparatus receives the notice and configures the status change based on the received notice.
