Error and Notification Messages

0027 DCB checksum error detected

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 this error occurs, please contact 3ware technical support. The drive’s DCB has been corrupted.

0028 DCB version unsupported

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 a unit that was created on a very old 3ware product is connected to a newer 3ware RAID controller, this message is posted and the 3ware RAID controller rejects the drive. Please contact 3ware technical support if this event occurs.

0029 Verify started

The 3ware RAID controller allows you to verify data integrity on a unit.The verification functions for different RAID levels are as follows:

•Single 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. Verify = Compare of Parity Data with User Data

For information on scheduling verifications, see “Scheduling Background Tasks” on page 76

002A Verify failed

This message indicates that the data integrity verification function (see message 0029) has terminated with an error. For each RAID level being verified, this may mean:

•Single 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. 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
