When dividing RAID groups into multiple logical units, set the sum total of the number of
logical blocks of each logical unit below the number of logical blocks per parity shown below.
However, when creating multiple parity groups in each RAID group, set them below the
number of logical blocks of one parity group multiplied by the number of parity groups.
The number of logical blocks of one parity group is shown below.
