Troubleshooting
AEN 008h AEN_UNCLEAN_SHUTDOWN
The ATA RAID controller has the ability to detect if the system has
been shutdown via the standard shutdown mechanism of the operat-
ing system (clean shutdown). If the system loses power or is reset
without going through the normal shutdown procedure, it is possi-
ble that the data on a redundant array may be out of synchroniza-
tion. The unclean shutdown detection will detect this case and force
the array to enter the rebuilding state. This has the effect of syn-
chronizing the array back to a fully redundant state.
To prevent unclean shutdowns, the user should always go through
the normal shutdown procedure for the operating system in use and
use an uninterruptible power supply (UPS) to prevent unclean shut-
downs due to sudden power loss.
AEN 009h AEN_APORT_TIMEOUT
The ATA RAID controller has a sophisticated recovery mechanism
to handle various types of failures of a disk drive. One such possi-
ble failure of a disk drive is a failure of a command that is pending
from the ATA RAID controller to complete within a reasonable
amount of time. If the ATA RAID controller detects this condition,
it notifies the user, prior to entering the recovery phase, by display-
ing this AEN.
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 ATA RAID controller,
various drive failures can be detected and if possible corrected. One
such drive failure is when the drive indicates back to the ATA
RAID controller that it was unable to complete a command. If the
drive returns an error to the ATA RAID controller, the user is noti-
fied by this AEN.
