  • a disk array comprising a plurality of independent disks that include a first location with a first RAID (Redundant Arrays of Independent Disks) type and a second location with a second RAID type;

    an array controller for controlling said disk array; and

    an auxiliary memory device connected to said disk array and said array controller for temporarily storing data outside of said disk array when said data is being changed from said first RAID type to said second RAID type within said disk array, wherein said array controller writes said data to the first location as the first RAID type, transfers said data from the first location to the auxiliary memory, reallocates said first location from said first RAID type to said second RAID type while said data is temporarily stored in said auxiliary memory, and then writes said data back to the first location as the second RAID type.
