3ware 9000 Series Serial ATA RAID Controller User Guide
(JBOD, RAID 0 and degraded arrays), drive ECC errors result in the 3ware
RAID controller returning failed status to the associated host command.
AEN 027h AEN_DCB_XSUM_ERROR
The 3ware RAID controller stores certain configuration parameters on a
reserved area of each disk drive called the Drive Configuration Block (DCB).
As part of power-on initialization, the 3ware RAID controller performs a
checksum of the DCB area to ensure consistency. If an error occurs, please
contact 3ware technical support. The drive’s DCB has been corrupted.
AEN 028h AEN_DCB_BAD_VERSION
During the evolution of the 3ware product line, the format of the DCB has
been changed to accommodate new features. The DCB format expected by
the 3ware RAID controller and the DCB that is written on the drive must be
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.
AEN 029h AEN_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.
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:
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.
