Automatic learn is not enabled
H 3
195 W BBU disabled; changing WB to WT E, F 4, 5
330 W Detected error with the remote battery connector cable N/A 6
Type
F= Fatal. W=Warning. C=Critical.
Indication
A) Sudden power loss or system hang, when BBU is not fully charged and Write Back mode is
forcefully enabled
B) The extended power loss to the system has resulted in the BBU being thoroughly discharged
before power recovery.
C) The specific virtual drive configuration may have changed, so that previous virtual drive
information cannot be recovered from BBU data
D) BBU failure or it is installed or connected incorrectly.
E) BBU not connected or not fully charged.
F) If WB mode was enabled before BBU charge, then it will be automatically re-enabled after the
charge
G) BBU not able to keep cache data long enough during system power off.
H) The battery requires a relearn cycle to re-calibrate itself.
Action
1) Check the BBU status to see if the BBU should be charged or replaced.
2) Check the cable, power connection, backplane, SATA/SAS port, and make sure the BBU is
installed and connected correctly.
3) Use RAID Web Console 2 or RAID BIOS Console to initiate a battery re-learn cycle.
4) Wait until the BBU is fully charged before rebooting the system.
5) WB can still be used through Bad BBU mode under RAID Web Console 2 but unexpected
power failure may cause data loss.
6) Check if the remote battery connector cable is properly connected and functional.
