AMCC 720-0138-00 manual 004E Battery capacity test started, 004F Cache synchronization skipped

Chapter 9. Troubleshooting

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.
