Logical and Hard Disk Drive Status Indications

•  A single hard disk drive failure  (indicated by a DDD  status in  the Bay/Array selection list) causes logical drives in that  array  that are assigned levels 1 and 5 to have a Critical status.  Data remains in logical drives  with a Critical status, but  you must replace the one defunct hard disk drive  promptly, because if two hard disk drives  were to fail, all of the data in the array would be lost.

   After you install a new hard disk drive, the Replace process  changes the drive status from DDD to OFL if  there is a Critical logical drive.  After the Rebuild process,  the hard disk drive status changes from OFL to ONL.

•  A single or multiple hard disk drive failure causes logical drives in  that array that  are assigned level 0 to have an Offline status.  Data in logical drives with an Offline status is lost.  However, with a multiple  disk drive  failure, when the defunct drives  are part of the same array, logical drives in that  array will have an Offline status.  This means that data is lost  in all the logical drives in that array, regardless of which RAID level  is assigned.
