Logical and Hard Disk Drive Status Indications (ServeRAID)

•  Procedure for replacing defunct drives

•  A single hard disk drive failure  (indicated by a DDD status in the Bay/Array selection list) generates a CRT status for the array's logical drives that are  assigned levels 1 and 5. Data in logical drives with a CRT is not lost.  You must replace the one defunct hard disk drive  promptly, and perform a Rebuild operation. If two hard disk drives were 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 RBL if  the array contains a CRT logical drive.  After the Rebuild process,  the hard disk drive status changes from RBL to ONL.

•  A multiple hard disk drive failure causes logical drives in  that array to have an Offline (OFL) status.  This means that data is lost  in all the logical drives in that array, regardless of which RAID level  is assigned.
