Abstract:
Provided is a storage control system in which a number of storage controllers are connected, and restored data is forwarded from one storage controller to the other storage controller. This storage control system is configured by a first storage controller and a second storage controller being connected in a mutually communicable manner, and which performs data processing according to a request from a host system, the first storage controller having a virtual volume associated with a logical volume of the second storage controller; a cache memory associated with the virtual volume; and a control unit for controlling the data processing between the cache memory and the virtual volume; wherein the control unit purges the storage area of the cache memory corresponding to the virtual volume accessed by the host system upon storing the restored data of the logical volume in the cache memory.
