Parity Check

A process whereby the integrity of the redundant data on fault-tolerant arrays (RAID 1, 3, and 5) is checked. The parity checking procedure on a logical drive recalculates the parity of data stripes in each of the logical drive’s RAID stripe sets and compares it with the stored parity. If the Generate Error Event option is selected and a discrepancy is found, an error is reported. If the Regenerate option is selected and a discrepancy is found, the new correct parity is substituted for the stored parity.
