Abstract:
In the computer system, a storage system provides a storage level virtual volume based on thin provisioning technology, to a physical server on which a virtual machine is defined. The storage system releases the area of the logical volume corresponding to the storage level virtual volume accessed by a virtual machine which is specified to be deleted, on the basis of storage level virtual volume conversion information which is managed by the storage system.
