3ware Escalade ATA RAID Controller User Guide • RAID 10. Verify = Compare of Mirror Sides • RAID 5. Verify = Parity Data = User Data When the verification starts, this AEN is posted to the user. AEN 02Ah AEN_VERIFY_FAILED This AEN indicates that the data integrity verification function (see AEN 029h) has terminated with an error. For each RAID level being verified, this may mean: • JBOD. 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. One side of the mirror does not equal the other side. • RAID 10. One side of the mirror does not equal the other side. • RAID 5. The parity data does not equal the user data. For JBOD and RAID 0, the most likely cause of the error is a grown defect in the drive. For out-of-synchronization mirrors, the error could be caused by improper shutdown of the array. This possibility applies to RAID 1, 10 and 5. A rebuild will re-synchronize the array. AEN 02Bh AEN_VERIFY_DONE This AEN indicates the data integrity verification function (see AEN 029h) was completed successfully. No errors were encountered. AEN 02Ch AEN_SECTOR_OVERWRITE If a read error is encountered during a rebuild and the user chooses to ignore the error, the sector in error is reallocated. The user is notified of the event by this AEN. 186 www.3ware.com
