Description

ABSTRACT:
A method and apparatus for reformatting a main storage device associated with a computer system. The storage device is reformatted by making use of a secondary storage device on which is stored a copy of the data stored on the main storage device. A reformatting process is run on the secondary storage device while the main computer system continues normal operation. When the reformatting process is completed, the secondary storage device is updated with the updates that were made on the main storage system while the reformatting process was run on the secondary system. Thereafter, the reformatted and updated data is either transferred to the main storage device, or the main storage device is physically replaced with the secondary storage device. In another aspect, non-standard programming techniques are employed to provide access to non-configured disc drives coupled to an AS/400.
