ABSTRACT:
A method for remotely copying volumes is disclosed. An identifier of a first disk subsystem of a first volume is obtained from a volume pair list. The first volume is a copy source or a copy destination of a volume pair. Route information including the identifier of the first disk subsystem is searched from a route list, which includes route information for determining an identifier of a second disk subsystem that relays a transmitting route of a command to the first disk subsystem and for determining an identifier of a third disk subsystem connected to a host computer. The identifier of the third disk subsystem indicated by the route information is obtained. A remote copy command of the first volume is issued to the third disk subsystem corresponding to the obtained identifier.
