Abstract
Methods that copy data from mirrored storage to auxiliary storage arrays co-located with primary storage arrays are provided. One method includes requesting a subset of the data from a backup system mirroring the set of data at a remote location in response to detecting an error in a storage device of an array of primary storage devices storing a set of data. The method further includes receiving the subset of the data from the backup system and storing the subset of the data in an array of auxiliary storage devices co-located with the array of primary storage devices in which the subset of the data can correspond to data stored on the storage device. Systems and computer program products for performing the above method are also provided.
