The present invention provides a storage device array system (24) and method for operating a storage device array system that provides for data transfers to and/or from a storage device array (30) during the reconstruction of data contained in a failed storage device (e.g. 32-7) onto a spare storage device (36). One embodiment of the invention provides for data transfers during the reconstruction of data on the spare storage device (36) onto a storage device that is replacing the failed storage device. Another embodiment of the invention allows data, contained in a storage device to or from which data can be written and read but only in a hindered manner, to be reconstructed on a spare storage device (36) using other storage devices (32) in the array (30). In this situation, write operations to the storage device array (30) are conducted in a manner that provides fault tolerance, i.e. the ability to continue the reconstruction process, in the event one of the other storage devices being used to reconstruct the data on the spare storage device (36) cannot provide the necessary data for reconstruction. <IMAGE> |
