Hot spare: what is it & how does it work?

A hot spare RAID is the spare disk in the array. It is not used in any way và is needed only at a certain time. This time comes in the sự kiện of a failure of one of the array drives. The RAID controller starts the RAID rebuilding procedure and uses a hot spare disk to replace the failed disk. Thus, the time period when the array data is not available is significantly reduced. Hot spare disks are possible in RAID 1, RAID 5 or RAID 6. Hot spares can be used for any failed disk in the storage array; that is, it is not allocated for a specific volume group. However, a hot spare disk must have certain characteristics: it must be identical with the disk that it protects.
