Abstract
Pairs are formed from a plurality of dispersed volumes and copying between the volumes is conducted by a series of remote operations from a management server. A management serverinstructs the generation of configuration setting filesto host computersselected so as to form copy pairs. If the configuration setting files are generated by host agents, the management serverinstructs copy start to a host computerhaving a primary volume. The host agentgenerates a prescribed command via a copy pair control moduleand causes a storage subsystemto execute copying between the volumes. When copying is completed, the management serveracquires the newest storage configuration information from the storage subsystemand updates configuration information DB
