ABSTRACT:
A storage system includes an application server that provides an application composed of a plurality of programs, a plurality of first volumes that store data that the programs use, and a plurality of second volumes set in pair states where replicas of the plurality of first volumes are stored. A program for managing the storage system controls a computer to execute the procedures of: identifying any one of the plurality of programs; identifying a first volume that the identified program uses; obtaining every second volume set in a pair state with the first volume; and summarizing the first volume and the obtained second volume for the identified program.
