The default operation of the ATA RAID controller is to abort a rebuild if an error is encountered.

AEN 005h AEN_REBUILD_DONE The ATA RAID controller has successfully completed a rebuild. The completion of the rebuild changes the state of the array from rebuilding to OK. The data is now redundant. AEN 006h AEN_INCOMP_UNIT At power on initialization time, the ATA RAID controller performs a "rollcall" of all drives attached to the card. After detection of the drives, the ATA RAID controller then uses an internal algorithm to logically connect drives that belong to the same array. If after rollcall a member of an array is not found, the INCOMPLETE UNIT AEN is sent. Examples of incomplete units are as follows: • • 4 drive RAID 5 with 1 drive missing. 2 drive RAID 1 with 1 drive missing. Replacing the missing or dead drive and initiating a rebuild will change the state of the array from an incomplete unit to OK. AEN 007h AEN_INIT_DONE The ATA RAID controller has completed the initialization sequence and performs the initialization step at array creation time of RAID levels 1, 10 and 5. For RAID 5, the data on the array is read and the resultant parity is written to the parity area on the array. For RAID 1 and 10, one half of the mirror is copied to the other half (mirrors are synchronized). 180 www.3ware.com

rebuild failure is most likely caused by the source drive of the
rebuild detecting some sort of read error. The default opera-
tion of the
ATA RAID controller
is to abort a rebuild if an error
is encountered. If it is desired to continue on error, the
Ignore

radio button can be checked prior to initiat-
ing a rebuild.
AEN 005h
AEN_REBUILD_DONE
The ATA RAID controller has successfully completed a rebuild.
The completion of the rebuild changes the state of the array from
rebuilding to OK. The data is now redundant.
AEN 006h
AEN_INCOMP_UNIT
At power on initialization time, the ATA RAID controller performs
a “rollcall” of all drives attached to the card. After detection of the
drives, the ATA RAID controller then uses an internal algorithm to
logically connect drives that belong to the same array. If after roll-
call a member of an array is not found, the
INCOMPLETE UNIT
AEN
is sent. Examples of incomplete units are as follows:
•
4 drive RAID 5 with 1 drive missing.
•
2 drive RAID 1 with 1 drive missing.
Replacing the missing or dead drive and initiating a rebuild will
change the state of the array from an incomplete unit to OK.
AEN 007h
AEN_INIT_DONE
The ATA RAID controller has completed the initialization sequence
and performs the initialization step at array creation time of RAID
levels 1, 10 and 5. For RAID 5, the data on the array is read and the
resultant parity is written to the parity area on the array. For RAID 1
