3ware Escalade Storage Switch User Guide Possible causes of APORT time-outs include a bad or intermittent disk drive, power cable or ATA interface cable. AEN 00Ah AEN_DRIVE_ERROR As part of the recovery mechanism of the storage switch, various drive failures can be detected and if possible corrected. One such drive failure is when the drive indicates back to the storage switch that it was unable to complete a command. If the drive returns an error to the storage switch, the user is notified by this AEN. AEN 00Bh AEN_REBUILD_STARTED The storage switch notifies the user whenever it starts a rebuild. The rebuild start may be user initiated (by selecting the rebuild button in the 3DM Disk Management Utility) or it may be auto initiated by a hot spare failover. In either case, the user is notified of the event by this AEN. AEN 00Ch AEN_INIT_STARTED The storage switch notifies the user by this AEN whenever it starts an Initialization. Initialization occurs at array creation time. AEN 00Fh AEN_SMART_FAIL The storage switch supports SMART Monitoring. whereby the individual drives automatically monitor certain parametric information such as error rates and retry counts. By monitoring this data, SMART may be able to predict a drive failure before it happens, allowing a user to schedule service of the array before it becomes degraded. The SMART status of each drive attached to the storage switch is monitored daily. If a failure of any drive is determined to be likely, the user is notified by this AEN. AEN 021h AEN_UDMA_DOWNGRADE The storage switch communicates to the ATA disk drives through the Ultra DMA (UDMA) protocol. This protocol ensures data integrity across the ATA cable by appending a Cyclical Redun- 152 www.3ware.com

Possible causes of APORT time-outs include a bad or intermittent
disk drive, power cable or ATA interface cable.

AEN_DRIVE_ERROR
As part of the recovery mechanism of the storage switch, various
drive failures can be detected and if possible corrected. One such
drive failure is when the drive indicates back to the storage switch
that it was unable to complete a command. If the drive returns an
error to the storage switch, the user is notified by this AEN.
AEN 00Bh
AEN_REBUILD_STARTED
The storage switch notifies the user whenever it starts a rebuild.
The rebuild start may be user initiated (by selecting the rebuild but-
ton in the 3DM Disk Management Utility) or it may be auto initi-
ated by a hot spare failover. In either case, the user is notified of the
event by this AEN.

vidual drives automatically monitor certain parametric information
such as error rates and retry counts. By monitoring this data,
SMART may be able to predict a drive failure before it happens,
allowing a user to schedule service of the array before it becomes
