Operation when failed Physical Device is replaced to recover RAID System
Using the RAID System continuously with the redundancy of a Logical Drive remaining degraded may cause the data in the Logical Drive to be lost when another Physical
Device is failed further. Recover a Logical Drive of degraded redundancy by Hot Spare or replacement of the failed Physical Device.
If Hot Spare or replacement of a failed Physical Device operates Rebuild, the status of the Physical Device changes during the rebuilding (with its [Status] changed to
[Rebuilding]).
