    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 228 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 229 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 230 Chapter 11. Troubleshooting 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.
  • Page 231 At this point, the 3ware RAID controller has a good copy of the requested data in its cache memory. It will then use this data to force the failing drive to reallocate the bad sector, which essentially repairs the sector.
  • Page 232 The DCB format expected by the 3ware RAID controller and the DCB that is written on the drive must be compatible. If an array that was created on a very old 3ware product is connected to a newer 3ware RAID controller, this AEN is posted and the 3ware RAID controller rejects the drive.
  • Page 233 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.

  • Page 235 176. 03Fh Flash file system error detected The 3ware RAID controller stores some configuration parameters as files in its flash memory. This AEN will be sent when a corrupted flash file system is found on the controller during boot-up. A further attempt will be made to repair the flash file system.
  • Page 236 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.

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.
