Abstract
A method for operating a storage controller reduces a probability of data loss in a storage system having redundant arrays of independent storage volumes (RAID) by identifying an old storage volume in a first location of a first RAID array of the storage system, and further by exchanging the old storage volume in the first location of the first RAID array with a second storage volume in a second location of a second RAID array of the storage system.
