ADU (Array Diagnostic Utility)
A diagnostic tool that collects comprehensive information about the array controllers in a
system and lists any problems detected.

for bad sectors, and data in the faulty sectors is remapped onto good sectors. Parity data
consistency is also checked for drives in RAID 5 or RAID ADG configurations. Operates as a

array
A set of physical drives configured into one or more logical drives. Arrayed drives have
significant performance and data protection advantages over non-arrayed drives.

performance by providing a buffer. Data integrity is protected by a backup battery and ECC
memory.
