RAID 0. Verify = Media scan
RAID 1 and 10. Verify = Comparison of mirror sides
RAID 5, 6, and 50. Verify = Comparison of parity data with user data

Tasks” on page 169. For information on verification of a unit, see “About
Verification” on page 155.
002A Verify failed
Event Type
Error
Cause
Verification of a unit has terminated with an error. For each RAID level being
verified, this may mean:
Single. A single drive returned an error, possibly because of a media
defect.
RAID 0. A single drive returned an error, possibly because of a media
defect.
RAID 1 and 10. One side of the mirror does not equal the other side.
RAID 5, 6, and 50. The parity data does not equal the user data.
For any RAID type, the most likely cause of the error is a grown defect in the
drive. For out-of-synchronization mirrors or parity, the error could be caused
by improper shutdown of the unit. This possibility applies to RAID 1, 5, 6, 10,
and 50.
