258 3ware Serial ATA RAID Controller User Guide
Background Information
The test estimates how many hours the Battery Backup Unit will be able to
back up the 3ware RAID controller in case of a power failure.
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. In addition, all units have their
write cache disabled until the test completes.
Action
None required.
See Also
See the Install Guide for your controller.
004F Cache synchronization skipped
Event Type
Warning
Cause
The cache synchronization that is normally performed when power is restored
after a power failure was skipped and write data is still being backed up in the
controller cache. This can occur if a unit was physically removed or became
inoperable during the power outage.
Action
Return missing drive(s) to the controller so that the missing write data can be
saved.
0050 Battery capacity test completed
Event Type
Information
Cause
The Battery Backup Unit has completed a battery capacity test.
The BBU is again able to backup the 3ware RAID controller and write cache
has been re-enabled for all units. (During the test, backup and write cache
were disabled).
