Abstract:
A virtual storage system includes a storage subsystem having virtual storage devices to emulate physical storage devices of an actual storage system. The virtual storage system has a controller to detect a status change of a particular physical storage device in the actual storage system. The status change includes at least one of loading of the particular physical storage device and ejecting of the particular physical storage device. In response to detecting the status change of the particular physical storage device, the controller performs synchronization between the virtual storage system and the actual storage system by updating a state of a corresponding virtual storage device in the virtual storage system.
