Avamar: Gen4s Hardware: Battery Temperature is High

The following error appears in the Avamar UI or the logs:

<MRMON145> Controller ID:  0   Battery temperature is high 

A Dial Home Service Request may also be sent.

The controller battery on the node fails because the temperature is too high. 
The root cause is unknown.

1. Log in to the Avamar server as admin, elevate to root, and load the SSH keys.

For instructions on loading keys, see article Avamar: How to Log in to an Avamar Server and Load Various Keys. 

2. Using the information from the UI event or the Dial Home Service Request:

a. Determine the node that produced the error message.

b. Connect to that node as root:

ssn 0.# --user=root

Where 0.# is the physical node number.

3. Extract /var/log/messages files using the applicable command below:

bunzip2 /var/log/messages*

gunzip /var/log/messages*

xz --decompress /var/log/messages*

4. Confirm that the logs show that the battery temperature is too high:

grep -i battery /var/log/messages*

Example output:

7. If the criteria above is matched, Create a Service Request providing the output above to determine if a node replacement is required.

-- Or --

If the criteria above are not met and the battery is operating as expected, no further action is required.
