Abstract
A system and method for controlling peer-to-peer remote copy (PPRC) operations initiated from one or more host devices that desire to store data contents written to a first storage system to a second storage system over a communications link. The system enables receipt and generation of copy services commands from host devices and the determination of whether a received command pertains to a copy service over an established PPRC relationship for that particular customer to enable that customer to perform storage operations effecting data written to a first storage server having source volumes and stored in a remote second storage system having target volumes. The copy services command effecting data contents of source volumes and/or remote target volumes will be enabled if it is determined that said PPRC relationship is already established for that customer; and, prevented if the received copy services command does effect any volume not already in a copy services relationship.
