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 1):
A computer system comprising: a management computer; a first storage apparatus; and a second storage apparatus,\n wherein a first logical device of the first storage apparatus and a second logical device of the second storage apparatus constitutes 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, and the second storage apparatus interchanges the virtual IDs of the third logical device and the second logical device with reception of a predetermined 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.
