Using The Battery Backup Units - LSI iBBU01 User Manual

Chapter 3
Using the Battery
Backup Units
This chapter explains how to monitor and maintain the MegaRAID BBUs
used with the MegaRAID 1078-based SAS RAID controllers. Most of the
MegaRAID BBU functions, such as battery recharging, occur
automatically. The following sections contain instructions for using the
BBUs:
•
Section 3.1, "Monitoring BBUs with the MegaRAID Configuration
Utilities"
•
Section 3.2, "Replacing Battery Backup Units"
•
Section 3.3, "Disposing of Battery Backup Units"
•
Section 3.4, "Transferring Cached Data from a Failed Controller"
You can monitor the battery status (temperature, voltage, and so on) in
these MegaRAID utility programs:
•
MegaRAID WebBIOS Configuration Utility
•
MegaCLI (command line utility)
•
MegaRAID Storage Manager Configuration Utility
Note: This chapter describes only the BBU-related features of the
MegaRAID utility programs. For complete information on
these utilities, see the MegaRAID SAS Software User's
Guide.
The MegaRAID utilities display a counter showing the number of times
the battery pack on the BBU has been recharged. When you replace a
BBU, you should run the utility program and reset this counter to zero for
the new BBU.
Note: LSI recommends that you replace the BBU once per year
or after 500 recharge cycles, whichever comes first.
