Hot-Spare Rebuild in Transparent RAID


Although the idea of global hot-spare rebuild is charming, one should not discount the value of human interaction and decision making when it comes to data restoration.
In fact, using this automatic restore feature is NOT recommended.
Instead, you are advised to manually inspect the defective drive first, backup the array if possible, and then attempt the restore process.

Hot-Spares are global in Transparent RAID. Any unused registered disk is an automatic candidate to be used as hot-spare.
