ABSTRACT:
An allocation apparatus of the present invention provides the mechanism that another logical volume of temporary number is automatically made in the storage system shared with plural servers, when it is recognized that the targeted logical volume is doubly allocated. By the present invention, the data destruction can be prevented by making the target server accessing another logical volume allocated automatically when the double allocation is detected. And the processing of a temporary allocation is continued until the alert message to the effect that the logical volume required from the target server is overlapped in the logical storage area is transmitted to the operator, the allocated another logical volume is approved by the operator, and the cancellation of overlapping allocation is confirmed.
