Note – RAID 1 provides protection against the failure of a single disk. When a disk
fails, it is rebuilt to a hotspare if one is available. This can greatly increase the level of
protection that RAID 1 provides.
Note – Even though multiple volumes can be created, the hotspare is a global
hotspare. Only one active hotspare is allowed for all volumes.
