Troubleshooting: Problems and Solutions reasonable amount of time, the device driver may issue a soft reset to the 3ware RAID controller and retry the command packet. AEN 002h AEN_DEGRADED_UNIT An error has been encountered and the array is operating in degraded (nonredundant) mode. The user should replace the bad drive as soon as possible and initiate a rebuild. AEN 003h AEN_CONTROLLER_ERROR The 3ware RAID controller has encountered an internal error. Please contact 3ware Customer Support as a replacement board may be required. AEN 004h AEN_REBUILD_FAIL The 3ware RAID controller was unable to complete a rebuild operation. This error can be caused by drive errors on either the source or the destination of the rebuild. However, due to ATA drives' ability to reallocate sectors on write errors, the rebuild failure is most likely caused by the source drive of the rebuild detecting some sort of read error. The default operation of the 3ware RAID controller is to abort a rebuild if an error is encountered. If it is desired to continue on error, you can set the Continue on Source Error During Rebuild policy for the unit on the Controller Settings page in 3DM. AEN 005h AEN_REBUILD_DONE The 3ware 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 3ware RAID controller performs a "rollcall" of all drives attached to the card. After detection of the drives, the 3ware 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. No rebuild is required if you replace the missing drive before loading the driver. 166 3ware 9000 Series Serial ATA RAID Controller User Guide

3ware 9000 Series Serial ATA RAID Controller User Guide

reasonable amount of time, the device driver may issue a soft reset to the

3ware RAID controller and retry the command packet.

AEN 002h AEN_DEGRADED_UNIT

An error has been encountered and the array is operating in degraded (non-

redundant) mode. The user should replace the bad drive as soon as possible

and initiate a rebuild.

AEN 003h AEN_CONTROLLER_ERROR

The 3ware RAID controller has encountered an internal error. Please contact

3ware Customer Support as a replacement board may be required.

AEN 004h AEN_REBUILD_FAIL

The 3ware RAID controller was unable to complete a rebuild operation. This

error can be caused by drive errors on either the source or the destination of

the rebuild. However, due to ATA drives’ ability to reallocate sectors on write

errors, the rebuild failure is most likely caused by the source drive of the

rebuild detecting some sort of read error. The default operation of the 3ware

RAID controller is to abort a rebuild if an error is encountered. If it is desired

to continue on error, you can set the Continue on Source Error During Rebuild

policy for the unit on the Controller Settings page in 3DM.

AEN 005h AEN_REBUILD_DONE

The 3ware 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 3ware RAID controller performs a

“rollcall” of all drives attached to the card. After detection of the drives, the

3ware 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. No rebuild is required if you

replace the missing drive before loading the driver.
