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.

A mass storage system having at least one input/output controllers in connection with a host computer is disclosed. The mass storage system also includes mirrored storage devices in connection with the input/output controllers through a global cache memory. Each mirrored pair of storage devices is assigned a common logical volume address, but is looked upon by the host computer as a single entity. The cache memory includes dynamically allocable cache slots, which correspond to each common logical volume address. When the host wishes to write data to a pair of mirrored storage devices, the contents of first write operation are written into the appropriate cache slot. However, when a second write operation is received by the input/output controllers, a determination is made as to whether the contents of the second write operation are already in the cache memory. If the contents are in the cache memory, a second write operation is not effectuated, thus improving system performance, but maintaining reliability in the system.
