Use the command in the following table to display BBU design parameters for the selected controller or controllers.
3.1.3.5 Display Current BBU Properties
Use the command in the following table to display the current BBU properties for the selected controller
or controllers.
3.1.3.6 Start BBU Learning Cycle
Use the command in the following table to start the BBU learning cycle on the selected controllers. A learning cycle is
a battery calibration operation performed by the controller periodically (approximately every three months) to
determine the condition of the battery.
Table 7 Display BBU Design Parameters

Table 8 Display Current BBU Properties
Convention MegaCLI -AdpBbuCmd -GetBbuProperties –aN|-a0,1,2|-aALL
Description Displays current properties of the BBU. The information displays in the following formats:
BBU Properties for Controller: x
Auto Learn Period: xxx sec
Next Learn Time:
Learn Delay Interval=: Value in hours, not greater than 168 hours (7 days)
Auto-Learn Mode=: Value can be 0, 1, or 2.
BBU Mode: xx. This property appears only for LSIiBBU08 batteries.
NOTE When the value in the Auto Learn Mode is set from 1 (Disabled) to 0 (Enabled), the controller firmware
resets the battery module properties to initiate an immediate battery learn cycle. The Learn Delay Interval field
and the Next Learn Time field will not be updated until the battery relearn is completed. After the relearning
cycle is completed, the value in the Next Learn Time field and in the Learn Delay Interval field will display the
new time (in seconds) of the next battery learning cycle.
Table 9 Start BBU Learning Cycle
Convention MegaCLI -AdpBbuCmd -BbuLearn -aN|-a0,1,2|-aALL
Description Starts the learning cycle on the BBU. No parameter is needed for this option.
