Information processing system, storage apparatus, and program

A second storage apparatus including second storage regions accessible by second virtual machines disposed in a second physical machine, wherein

• in accordance with occurrence of predetermined abnormality in first virtual machines disposed in first physical machine or first storage apparatus accessible by the first virtual machines, when the second virtual machines execute first processing executed by the first virtual machines, the second storage apparatus stores first information in which information for identifying virtual machines that execute the first processing among the second virtual machines and information for identifying storage regions accessed by the identified virtual machines during the execution of the first processing among the second storage regions are associated with each other, and
• before the first virtual machines re-execute the first processing, the second storage apparatus transmits the first information to the first storage apparatus to reconfigure a configuration of the first storage regions to be same as a configuration of a storage region corresponding to the first information among the second storage regions.
