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.
0052 Battery health check completed
The Battery Backup Unit evaluates periodically 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 has completed.
0053 Battery capacity test is overdue
The recommended time interval for running the battery capacity test is once
every 4 weeks. If a battery capacity test has not been completed in the last 4
weeks this message will be sent to the host, and will be sent again once every
week thereafter.
