consistency check command
The controller continuously performs a verification on a redundant
array to data integrity. In the case of RAID 1 or 10, consistency
checks assure that the data between like blocks match. In the case
of a RAID 5, consistency checks assure that data in the stripe and
the calculated parity for the stripe match.
