Monitoring Batteries in the Compute Servers

To monitor the battery change capacity in the compute servers:

# /opt/MegaRAID/MegaCli/MegaCli64 -AdpBbuCmd -a0 | grep "Full Charge" -A5 | sort \
| grep Full -A1

The following is an example of the output from the command:

Full Charge Capacity: 1357 mAh
Max Error: 2 %

You should proactively replace batteries that have a capacity less than 800 milliampere hour (mAh) and a maximum error less than 10%. Immediately replace any battery that has less than 674 mAh or a maximum error greater than 10%.

To monitor the battery temperature:

/opt/MegaRAID/MegaCli/MegaCli64 -AdpBbuCmd -a0 | grep BatteryType; \
/opt/MegaRAID/MegaCli/MegaCli64 -AdpBbuCmd -a0 | grep -i temper

The following is an example of the output from the command:

BatteryType: iBBU08
Temperature: 38 C
  Temperature                  : OK
  Over Temperature        : No

If the battery temperature is greater than or equal to 55 degrees Celsius, then determine the cause, and correct the problem.

Note:

Storage servers generate an alert when the battery charge capacity is insufficient, the temperature is high, or the battery should be replaced.
