A drive can be assigned as the Local Spare Drive that serves one specific logical drive, or as a Global Spare Drive that participates in the rebuild of any logical drive. Spares automatically joins a logical drive when a drive fails. Spares are not applicable to logical drives that have no data redundancy (NRAID and RAID 0).
