Provided is a calculator system that, while maintaining a high availability (HA) configuration, is capable of transitioning one or both logical devices in a HA pair to another storage device. When a first HA pair is configured with a first logical device of a first storage device and a second logical device of a second storage device, the first logical device is virtualized on a third storage device and is set to correspond with a third logical device of the third storage device. A fourth storage device virtualizes the second logical device and sets the second logical device to correspond with a fourth logical device of the fourth storage device. After a second HA pair has been configured with the third logical device and the fourth logical device, the data on the first logical device is transitioned to the third storage device and managed as data on the third logical device. The data on the second logical device is transitioned to the fourth storage device and managed as data on the fourth logical device. |
