A process that enables checking the integrity of the redundant data on
fault-tolerant arrays, such as RAID 6. Parity checking on a logical drive

strip sets and compares it with stored parity. When a discrepancy is
discovered, an error is reported and the new correct parity is substituted
for the stored parity.
