A method, medium and apparatus for transparently virtualizing storage in an operating computer system. The method includes a computer's recognizing a storage device connected to the computer through a physical connection, a storage virtualizing device's virtualizing the storage device, the computer's relating the storage device and the virtualized storage device and, finally, the computer's failing over to the virtualized storage device on the computer. While virtualizing, the storage virtualizing device, the physical connection and the first recognition maybe maintained through the step of virtualizing. While virtualizing, the method may recognize the storage device through a physical connection, virtualize the storage device and expose the virtualized storage device. In an further form of the method, from the time of recognition through the time of failing over, no I/O is interrupted by the method. |
