Replacing Faulty HDD during RAID Operation
When one HDD errors ([1down]) in RAID5 mode, the data on the remaining HDDs can be read and recovery is possible.
When two HDDs errors ([2down]) in RAID6 mode, the data on the remaining HDDs can be read and recovery is possible.
Important:
•Do not turn off the power until RAID is recovered. Data recovery may not be done normally when the power is turned off.
Note:
•When errors (1down) occur in RAID6 mode, quickly execute error recovery.
