1. A method of processing requests relating to data movement for network storage devices, the method comprising: receiving file movement instructions to move a first data file from a first network storage device to a second network storage device; moving the first data file from a first location at the first network storage device to a second location at the second network storage device, said moving comprising providing access to the first data file by a client machine during said moving; and automatically mapping the first location at the first network storage device to the second location at the second network storage device so that a client machine can access the first data file using a data file pathname that does not change when the data file is moved from the first location to the second location to thereby render the data file move transparent to the client machine.
