Abstract
A metadisk driver functionally intermediate a computer operating system and one or more metadrivers and underlying layered drivers provides a driver rename/exchange function which does not depend on any particular driver having knowledge of the private data structures of any of the other drivers. The rename/exchange technique implemented thereby may be conducted while the underlying devices are on-line and comprise atomic operations which are, therefore, recoverable inasmuch as the operation will have either been completed or will not be committed in the event of any interruption.
