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
