Chapter 11. Troubleshooting
02Ch Source drive ECC error overwritten
If a read error is encountered during a rebuild and the user chooses to ignore
the error, the sector in error is reallocated. The user is notified of the event by
this AEN.
02Dh Source drive error occurred
If an error is encountered during a rebuild operation, this AEN is generated if
the error was on a source drive of the rebuild. Knowing if the error occurred
on the source or the destination of the rebuild is useful for troubleshooting.
02Eh Replacement drive capacity too small
The 3ware RAID controller notifies the user by this AEN when the
replacement drive capacity is smaller than required. The replacement drive
must be equal to or greater capacity than the drive it's replacing.
02Fh Verify not started; unit never initialized
This AEN will be sent by the controller when a verify operation is attempted
but the unit has never been initialized before. The unit will transition to
initializing mode.
030h Drive not supported
3ware 8000 and 9000 series Serial ATA Controller only support UltraDMA-
100/133 drives when using the parallel to serial ATA converter. This AEN
indicates that an unsupported drive was detected during rollcall or a hot add.
This AEN also could indicate that the Serial to Parallel converter was
jumpered in the wrong place. The converter must be correctly jumpered to
correspond to UDMA 100 or 133 drives.
032h Spare capacity too small for some units
This AEN is sent by the controller when it finds a valid hot spare but the
capacity is not sufficient to use it for a drive replacement.
033h Migration started
This AEN is sent when migration of a unit is started.
