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.
