Abstract
A first storage system manages a first volume, with a first internal volume identifier, and to provide the first volume with a given first virtual volume identifier to a server. A second storage system manages a second volume, with a second internal volume identifier, and to provide the second volume with the given first virtual volume identifier to the server. A third storage system manages a third volume. The first storage system manages a first copy pair between the first volume and the third volume with a first internal copy identifier, and to provide a first copy pair with a given virtual copy pair identifier to the server. The second storage system manages a second copy pair between the second volume and the third volume with a second internal copy identifier, and to provide a second copy pair with the given virtual copy pair identifier to the server.
