Troubleshooting errors result in the ATA RAID controller returning failed status to the associated host command. AEN 027h AEN_DCB_XSUM_ERROR The ATA 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 ATA 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 Escalade product line, the format of the DCB has been changed to accommodate new features. The DCB format expected by the ATA RAID controller 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 ATA RAID controller, this AEN is posted and the ATA RAID controller rejects the drive. Please contact 3ware technical support if this event occurs. 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 www.3ware.com 185

Block (DCB). As part of power-on initialization, the ATA RAID

The drive’s DCB has been corrupted.

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 ATA RAID controller 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
ATA RAID controller, this AEN is posted and the ATA RAID con-
troller rejects the drive. Please contact 3ware technical support if
this event occurs.

The ATA RAID controller allows the user to verify data integrity on
