Abstract
A method is disclosed to reconfigure a storage array. The method supplies a data storage and retrieval system comprising (N) data storage device assemblies, wherein each of those (N) data storage device assemblies comprises (M) data storage devices, wherein (N) is greater than or equal to 2, and wherein (M) is greater than or equal to 2. The method configures those (N) data storage device assemblies to comprise a spare data storage device assembly and a first storage array comprising the remaining (N−1) data storage device assemblies. In the event Applicants' method detects a failed data storage device disposed in the first storage array, then the method forms a second storage array comprising the first storage array, except the failed data storage device, in combination with a data storage device disposed in the spare data storage device assembly.
