    Abstract: Availability of an information system including a storage apparatus and a host computer is improved. A host system includes a first storage apparatus provided with a first volume for storing data, and a second storage apparatus for storing the data sent from the first storage apparatus. In case of a failure occurring in the first storage apparatus, the host sends the data to be sent to the first storage apparatus to the second storage apparatus. The same identification number is used by the host computer for accessing data stored in the first volume via a first virtual volume and for accessing data stored in a second volume of the second storage system via a second virtual volume.
