6.1.3 Monitoring the iBBU with the MegaRAID Storage Manager
When MegaRAID Storage Manager software is running, you can monitor
the status of all of the BBUs connected to controllers in the
server. If a BBU is operating normally, the icon looks like this:
If it has failed, a red dot appears next to the icon.
To show the properties for a BBU, perform the following steps:
1. Click the Physical tab to open the physical view.
2. Select the BBU icon in the left panel.
The BBU properties appear in the right panel and include the following:

The number of times the BBU has been recharged ( Cycle Count )

The full capacity of the BBU, plus the percentage of its current state
of charge, and the estimated time until it will be depleted

The current BBU temperature, voltage, current, and remaining
capacity

If the battery is charging, the estimated time until it is fully charged
6.1.3.1 Battery Learn Cycle
Learn Cycle is a battery calibration operation performed by the controller
periodically to determine the condition of the battery. You can start

battery learn cycles, disable automatic learn cycles.
If you enable automatic learn cyles, you can delay the start of the learn
cycles for up to 168 hours (7 days). If you disable automatic learn cycles,
Description Sets the BBU properties on the selected controller(s) after reading from the file.
The information displays in the following formats:
autoLearnPeriod = 1800Sec
nextLearnTime = 12345678Sec Seconds past 1/1/2000
learnDelayInterval = 24hours Not greater than 7 days
autoLearnMode = 0 0 – Enabled, 1 - Disabled, 2 – WarnViaEvent.
1. NOTE: You can change only two of these parameters, learnDelayInterval and
autoLearnMode.
