(2) Operation of Rebuilding Data to Hot Spare Disk

Copy Back Mode: Off (Default)

After the data is restored, the replaced disk is automatically designated as the hot spare disk. When 
replacing the hot spare disk with the same capacity/rotation speed, data is not copied back. However, 
when a hot spare disk with larger capacity/higher rotation speed is replaced with a disk drive of 
smaller capacity/lower rotation speed, the data is copied back to its original location (on the replaced 
disk).

Copy Back Mode: On

When replacing a failed disk with a new normal disk, and after the data restore has completed, data 
on the hot spare disk is copied back to the new disk. When copy back mode is in progress, 
scheduled maintenance (multi hot spare disk function) is not available. Refer to NEC 
StorageManager for copy back mode setting.
