3ware Escalade ATA RAID Controller User Guide
AEN 029h AEN_VERIFY_STARTED
The ATA RAID controller allows the user to verify data integrity on an
array.The verification functions for different RAID levels are as follows:
■
JBOD. Verify = Media Scan
■
RAID 0. Verify = Media Scan
■
RAID 1. Verify = Compare of Mirror Sides
■
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.
