INFORMATION PROCESSING SYSTEM AND DATA RECOVERY METHOD
First Claim
1. An information processing system, in which a computer having a first storage device and a storage controller having a second storage device are connected via a network, whereinthe computer manages an update status of the first storage device, and when able to communicate with the storage controller, and transfers the data written to the first storage device to the storage controller, independently of data writing to the first storage device,the storage controller writes the transferred data to the second storage device,the computer, upon detecting a failure of the first storage device, notifies the storage controller of the failure, andthe storage controller, which receives the failure information notification, selects a third storage device that is capable of being used by the computer, and copies the data, which have been written to the second storage device, to the selected the third storage device.

8. A data recovery method for recovering data stored in a storage area of a computer, comprising the steps of:
-
managing by the computer an update status of a first storage device of the computer, and, when the computer is able to communicate with a storage controller, transferring the data written to the first storage device to the storage controller, independently of data writing to the first storage device, and writing by the storage controller the transferred data to a second storage device; notifying, upon detecting a failure of the first storage device, the storage controller of failure information by the computer; and selecting, by the storage controller that has received the failure information notification, a third storage device that is capable of being used by the computer, and copying the data, which have been written to the second storage device, to the selected the third storage device. - View Dependent Claims (9, 10, 11, 12, 13, 14)
