3.1.5 Monitoring and Managing BBU Units with the MegaRAID Storage Manager Configuration
Utility
MegaRAID Storage Manager software enables you to configure, monitor, and maintain storage configurations on
Avago SAS controllers. The MegaRAID Storage Manager graphical user interface (GUI) makes it easy for you to create
and manage storage configurations.
When MegaRAID Storage Manager software is running, you can monitor and manage the status of all of the BBU units
connected to controllers in the server. If a BBU unit is operating normally, the icon
displays. If it has failed, a red
dot appears next to the icon.
NOTE To increase the life of a battery, the battery is not fully charged. Band
Gap charging keeps the maximum battery charge within a band
comfortably above the time requirement instead of keeping the
battery charged to the maximum level. However, when a learn cycle is
required, the battery is fully charged because a learn cycle starts only
after the battery is fully charged.
To show the properties of a BBU unit, perform the following steps:
1. On the MSM main menu screen, click the Physical tab to open the physical view.
2. Select the BBU icon in the left panel.
The BBU properties, such as the battery type, temperature, and voltage appear in the right panel and include the
following:
— The number of times the BBU unit has been recharged (Cycle Count)
