Abstract:
A computer system includes a management computer, a first storage apparatus, and a second storage apparatus. A first logical device of the first storage apparatus and a second logical device of the second storage apparatus constitute a remote copy pair. The second logical device and a third logical device of the second storage apparatus constitute a copy pair. The second logical device and the third logical device have virtual IDs to be recognized by an issuer of an I/O request. The second storage apparatus interchanges the virtual IDs of the third logical device and the second logical device with reception of a command from the management computer as a trigger during processing of the I/O request from the issuer of the I/O request to the third logical device, thereby switching an access destination of the issuer of the I/O request from the third logical device to the second logical device.

Claim (Index 8):
The method for controlling a storage apparatus according to  claim 6 , wherein\n the second storage apparatus restores differential data from the third logical device to the second logical device before interchanging the virtual IDs of the third logical device and the second logical device in the third step.
