repair the flash file system. These files usually get corrupted when a flash
operation is interrupted by events such as power failures.
AEN 040h AEN_FLASH_FILE_REPAIRED
This AEN will be sent if a corrupted flash file system is successfully repaired.
Some of the flash files with insufficient data may be lost in the operation. The
configuration parameters which are lost will then return to their default
values.
AEN 041h AEN_UGT_CORRUPT
The 3ware RAID controller tries to keep the unit numbers persistent across
soft resets. This AEN will be sent if unit number assignments were lost from
some unknown reasons.(This event rarely happents. Please contact AMCC
3ware technical support if this event occurs.
AEN 042h AEN_PRIMARY_DCB_ERROR
This AEN will be sent when the controller finds error in reading the primary
copy of the Disk Configuration Block (DCB). The back-up copy of the DCB
will be read if this error occurs. If a valid DCB is found, the primary DCB is
re-written to rectify the errors found.
AEN 043h AEN_BACKUP_DCB_ERROR
This AEN will be sent when the controller sees a latent error in the backup
Disk Configuration Block (DCB). A scrubbing activity will be started to
repair any sector errors on getting this error. An effort is made to read the
backup DCB even when the primary DCB is successfully read. When an error
occurs here, this is a latent error that needs to be addressed before any future
errors so this DCB is re-written with the primary copy to rectify the errors
found.
AEN 044h AEN_VOLTAGE_NORMAL
The Battery Backup Unit measures and evaluates the battery pack voltage on
a continuous basis. If the voltage falls outside the acceptable range then
comes back within the acceptable range, this AEN will be posted to the host.
AEN 045h AEN_VOLTAGE_LOW_WARN
The Battery Backup Unit measures and evaluates the battery pack voltage on
a continuous basis. If the voltage is below the warning threshold, this AEN
will be posted to the user. When this event happens, the Battery Backup Unit
is still able to backup the 3ware RAID controller, but the user should replace
the battery.
