Abstract
An input/output method is provided which assures data consistency of a file spreading over a plurality of logically significant volumes or files distributed among a plurality of volumes. A storage subsystem at a main site handles as one group those input/output requests issued in a single process from a computer which call for data update on a plurality of logically significant volumes. The update request is executed on a plurality of volumes by group to implement the updating of volumes at a remote site en masse.
