Abstract

At the time of remote copy, World Wide Name is used in order for the storage systems to recognize each other and be connected together. The World Wide Name is information unique to port, and depends upon boards having ports. The storage system as the copy source sends a login request including other information than the World Wide Name from which the login from the storage system can be recognized, while the storage system on the login receiving side sends back information indicative of a port that can participate in the remote copy, so that a storage system and port hopeful for remote copy can be decided from the remote site only when the login from the storage system can be recognized.
