Information
Cause
The 3ware RAID controller has started verifying the data integrity of a unit.
The verification functions for different RAID levels are as follows:
•
Single. Verify = Media scan
• 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
Action
Allow verify to complete to identify any possible data integrity issues.

Tasks” on page 163. For information on verification of a unit, see “About

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.
