Running a Device Rebuild

If a single device in a fault tolerant system fails, the system is spared data loss by
virtue of the striping with parity present across the logical drive (RAID 3,
RAID 5) or the total redundancy of data (RAID 1, RAID 0+1). The failed drive
needs to be replaced and the failed drive's data must be rebuilt on a new drive to
restore the system to fault tolerance once again.
The device rebuild function performs this task. A failed drive's data can be rebuilt
to:
The original drive if this drive happens to be still functional
A hot spare (standby) drive present for just this purpose, or
A drive inserted in place of the failed drive.
