Chapter 11. Troubleshooting
00Eh Initialize failed
The 3ware RAID controller was unable to complete the initialization. This
error can be caused by unrecoverable drive errors. When this error occurs, the
unit will go back to degraded mode if possible.
00Fh SMART threshold exceeded
The 3ware RAID controller 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 3ware RAID controller is monitored daily. If a failure of any
drive is determined to be likely, the user is notified by this AEN.
3ware recommends that you replace any drive that has the SMART attribute
exceeded.

01Eh Unit inoperable

the timer expires (20 seconds) there will be no AEN since there were no IO
errors.
