compatible. If an array that was created on a very old 3ware product is
connected to a newer 3ware RAID controller, this AEN is posted and the
3ware RAID controller rejects the drive. Please contact 3ware technical
support if this event occurs.
029h Verify started
The 3ware RAID controller allows the user to verify data integrity on an
array.The verification functions for different RAID levels are as follows:
• Single, JBOD, and Spare. Verify = Media Scan
• RAID 0. Verify = Media Scan
• RAID 1. Verify = Compare of Mirror Sides
• RAID 10. Verify = Compare of Mirror Sides
• RAID 5 and 50. Verify = Compare of Parity Data with User Data
When the verification starts, this AEN is posted to the user.
02Ah 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:
• 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. 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 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 array. This possibility applies to RAID 1, 10, 5,
and 50. A rebuild will re-synchronize the array.
02Bh Verify completed
This AEN indicates the data integrity verification function (see AEN 029h)
was completed successfully.
