Pre-failure replacement with redundancy - Redundant Copy

The Redundant Copy function enables preventive replacement of a disk while ensuring data redundancy. When a disk is diagnosed for preventive replacement, this function creates data using other disks in the same RAID group and writes that data to a hot-spare.
Once the write is complete, the hot-spare takes over its functions and the disk at fault is detached.
