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, JBOD, and Spare. 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.
