Abstract:
In a computer system, when a first high availability (HA) pair is configured with a first logical device of a first storage apparatus and a second logical device of a second storage apparatus, the first logical device is virtualized on a third storage apparatus and is set to correspond with a third logical device of the third storage apparatus. A fourth storage apparatus virtualizes the second logical device and sets the second logical device to correspond with a fourth logical device of the fourth storage apparatus. After a second HA pair is configured with the third logical device and the fourth logical device, the data on the first logical device is migrated to the third storage apparatus and managed as data on the third logical device. The data on the second logical device is migrated to the fourth storage apparatus and managed as data on the fourth logical device.
