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 Escalade product line, the format of the
DCB has been changed to accommodate new features. The DCB
format expected by the storage switch and the DCB that is written
on the drive must be compatible. If an array that was created on a
very old Escalade product is connected to a newer Escalade storage
switch, this AEN is posted and the storage switch rejects the drive.
Please contact 3ware technical support if this event occurs.
AEN 029h AEN_VERIFY_STARTED
The storage switch allows the user to verify data integrity on an
array.The verification functions for different RAID levels are as fol-
lows:
• 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.
