    The Battery Backup Unit (BBU) is an add-on card that can be attached to a 3ware 9000 RAID controller to supply power from a battery pack in the event of a system power loss. This allows the controller to use write-caching for optimal performance and to preserve data in the event of a system power failure.

    AEN Error Message Details 001h Controller reset occurred The 3ware RAID controller has detected a soft reset from the device driver. If the 3ware RAID controller fails to respond to the device driver within a reasonable amount of time, the device driver may issue a soft reset to the 3ware RAID controller and retry the command packet.
  • Page 238 008h Unclean shutdown detected The 3ware RAID controller has the ability to detect if the system has been shutdown via the standard shutdown mechanism of the operating system (clean shutdown). If the system loses power or is reset without going through the normal shutdown procedure, it is possible that the data on a redundant array may be out of synchronization.
  • Page 239 One such drive failure is when the drive indicates back to the 3ware RAID controller that it was unable to complete a command. If the drive returns an error to the 3ware RAID controller, the user is notified by this AEN.
  • Page 240 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.

This AEN will be sent if unit number assignments were lost from some unknown reasons.(This event rarely happens. Please contact AMCC 3ware technical support if this event occurs.)
  • Page 247 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.
  • Page 248 If the temperature is below a 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 pack.
  • Page 249 This AEN is posted when the Battery Backup Unit starts a battery test. The test estimates the battery capacity in hours, which is how long the Battery Backup Unit can back up the 3ware RAID controller. This test performs a full battery charge/discharge/re-charge cycle and may take up to 20 hours to complete.
