/sys$common/syshlp/MSA_UTIL_HELP.HLB  —  ADD  UNIT  Qualifiers  /RAID_LEVEL
         Specifies the RAID type of the UNIT. The support values for this
         qualifier are 0, 1, 5, 50, and 60.

         -  RAID 0 is Data Striping
         -  RAID 1 is Disk Mirroring
         -  RAID 5 is Data Striping with Striped Parity
 	-  RAID 50 is Data Striping across RAID 5 arrays
 	-  RAID 60 is Data Striping across RAID 6 arrays

         Format:
                 /RAID=[(0 | 1 | 5 | 50 | 60)]

        Note:

        - When minimum four disks are supplied to create a RAID 1 unit,
          the controller creates a RAID 10 unit; which is Data Striping
          across RAID 1 arrays.

        - SHOW UNITS displays "Logical Volume Raid Level: RAID 1" for the
          RAID 10 units. If the data disks used by logical unit number (LUN)
          are more than two disks, the implementation of that LUN is
          RAID 10.
