Abstract

A volume-to-volume copy method on a DASD storage subsystem concurrent with host CPU application execution and referencing of data on a primary. In this method, updates to data made on a primary volume after the element was copied during a first pass will be deferred and copied only during a second pass rather than interrupting the first pass. This accumulation and deferral of updates to a second pass shortens the volume copy time and reduces application referencing delay.
