Abstract:
In this invention, a processor generates a first virtual storage device, secures a first resource from a physical resource within a storage device, allocates the first resource to the first virtual storage device, and, using the first resource, generates a plurality of virtual volumes within the first virtual storage device. If a request is received to execute a specified operation on a specified virtual volume from among the plurality of virtual volumes, the processor determines whether an estimate can be made of a first resource volume which is the volume of the first resource which will be used if the specified operation is executed on the specified virtual volume, and if the estimate of the first resource volume cannot be made, generates a second virtual storage device. The processor identifies a second resource, from among the first resource, which is used in the specified virtual volume, allocates at least the second resource to the second virtual storage device, and changes the affiliation of the specified virtual volume from the first virtual storage device to the second virtual storage device. The processor executes the specified operation on the specified virtual volume.
