Online Activity LED on the front of the drive stops blinking The following cases are exceptions e In RAID 6 ADG configurations any two drives in the array can be replaced simultaneously e In RAID 1 0 configurations any drives that are not mirrored to other removed or failed drives can be simultaneously replaced offline without data loss Automatic data recovery rebuild When you replace a hard drive in an array the controller uses the faulttolerance information on the remaining drives in the array to reconstruct the missing data the data that was originally on the replaced Replacing moving or adding hard drives 29 drive and write it to the replacement drive This process is called automatic data recovery or rebuild If fault tolerance is compromised this data cannot be reconstructed and is likely to be permanently lost If another drive in the array fails while fault tolerance is unavailable during rebuild a fatal system error can occur and all data on the array is then lost In exceptional cases however failure of another drive need not lead to a fatal system error These exceptions include e Failure after activation of a spare drive e Failure of a drive that is not mirrored to any other failed drives in a RAID 1 0 configuration e Failure of a second drive in a RAID 6 ADG configuration Time required for a rebuild The time required for a rebuild varies considerably depending on several factors
