| 574.It Cm start learn 575Start a battery relearn. 576.It Cm bbu Ar setting Ar value 577Update battery backup unit (BBU) properties related to battery relearning. 578The following settings are configurable: 579.Bl -tag -width indent 580.It Cm learn-delay 581Add a delay to the next scheduled battery relearn event. This setting is 582given in hours and must lie in the range of 0 to 255. 583.It Cm autolearn-mode 584Enable or disable automatic periodic battery relearning. 585The setting may be set to 586.Dq enable 587or 588.Dq disable 589to respectively enable or disable the relearn cycle. 590Alternatively, a mode of 0, 1 or 2 may be given. 591Mode 0 enables periodic relearning, mode 1 disables it, and mode 2 disables 592it and logs a warning to the event log when it detects that a battery relearn 593should be performed. 594.It Cm bbu-mode 595Set the BBU's mode of operation. This setting is not supported by all BBUs. 596Where it is supported, the possible values are the integers between 1 and 5 597inclusive. 598Modes 1, 2 and 3 enable a transparent learn cycle, whereas modes 4 and 5 do not. 599The BBU's data retention time is greater when transparent learning is not used. |
