004D Battery temperature is too high

The Battery Backup Unit measures and evaluates the battery pack
temperature on a continuous basis. If the temperature is too high to operate,
this message will be posted. You should check that there is enough airflow
around the Battery Backup Unit. When this event happens, the Battery
Backup Unit becomes not ready and is unable to backup the 3ware RAID
controller. You must replace the battery pack if the temperature error persists.
The use of a PCI card in the slot adjacent to the BBU is not recommended and
may result in the battery temperature being exceeded.

004E Battery capacity test started

This message 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. During this test the Battery Backup Unit cannot backup the 3ware
RAID controller; all units have their write cache disabled until the test
completes.

004F Cache synchronization skipped

The 3ware RAID controller performs cache synchronization when system
power is restored following a power failure. This message is posted when the
cache synchronization was skipped and write data is still being backed up in
the controller cache. This can occur if a unit that was present before the power
failure was physically removed or became inoperable before system power
was restored.

0050 Battery capacity test completed

This message is posted when the Battery Backup Unit completes a battery
capacity test. All units will have their write cache settings restored to their
original values since the Battery Backup Unit is now able to backup the 3ware
RAID controller.

0051 Battery health check started

The Battery Backup Unit periodically evaluates the health of the battery and
its ability to backup the 3ware RAID controller in case of a power failure.
This message is posted to the host when this health check is started.
