Logical Drive Fault Tolerance.
              
This shows the fault tolerance mode of the logical drive.
To change the fault tolerance mode, run the configuration
utility.
              
The following values are valid for the Logical Drive Fault
Tolerance:
              
None (2)
  Fault tolerance is not enabled.  If a physical drive reports
  an error, the data cannot be recovered by the array
  controller.
              
Mirroring (3)
  For each physical drive, there is a second physical drive
  containing identical data. If a drive fails, the data can be
  retrieved from the mirror drive.
              
Data Guard (4)
  One of the physical drives is used as a data guard drive and
  contains the exclusive OR of the data on the remaining drives.
  If a failure is detected, the External Array Controller
  rebuilds the data using the data guard information plus
  information from the other drives.
              
Distributed Data Guard (5)
  Distributed Data Guarding, sometimes referred to as RAID 5,
  is similar to Data Guarding, but instead of storing the parity
  information on one drive, the information is distributed
  across all of the drives.  If a failure is detected, the array
  controller rebuilds the data using the data guard information
  from all the drives.
              
Advanced Data Guarding (7)
  Advanced Data Guarding (RAID ADG) is the fault tolerance method
  that provides the highest level of data protection.  It
  `stripes` data and parity across all the physical drives in the
  configuration to ensure the uninterrupted availability of
  uncorrupted data.  This fault-tolerance method is similar to
  distributed data guard (RAID 5) in that parity data is
  distributed across all drives in the array, except in RAID ADG
  the capacity of multiple drives is used to store parity data.
  Assuming the capacity of 2 drives is used for parity data,
  this allows continued operation despite simultaneous failure of
  any 2 drives in the array, whereas RAID 4 and RAID 5 can only
  sustain failure of a single drive.
