The following error appears in the Avamar UI or the logs: <MRMON154> Controller ID: 0 Battery relearn timed out
This is under review by the vendor.
1. Log in to the Avamar server as admin, elevate to root, and load the SSH keys. For instructions on loading keys, see 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. Review the messages log (/var/log/messages) for Battery relearn events: grep -i "battery relearn" /var/log/messages Jul 29 13:37:12 AVATPCKVS41N05 MR_MONITOR[8625]: <MRMON157> Controller ID: 0 Battery relearn will start in 4 days Jul 31 13:37:48 AVATPCKVS41N05 MR_MONITOR[8625]: <MRMON158> Controller ID: 0 Battery relearn will start in 2 days Aug 1 13:37:33 AVATPCKVS41N05 MR_MONITOR[8625]: <MRMON159> Controller ID: 0 Battery relearn will start in 1 day Aug 2 08:37:13 AVATPCKVS41N05 MR_MONITOR[8625]: <MRMON160> Controller ID: 0 Battery relearn will start in 5 hours Aug 2 13:38:24 AVATPCKVS41N05 MR_MONITOR[8625]: <MRMON155> Controller ID: 0 Battery relearn pending: Battery is under charge Aug 2 13:39:28 AVATPCKVS41N05 MR_MONITOR[8625]: <MRMON151> Controller ID: 0 Battery relearn started Aug 2 13:40:36 AVATPCKVS41N05 MR_MONITOR[8625]: <MRMON152> Controller ID: 0 Battery relearn in progress Aug 2 13:40:36 AVATPCKVS41N05 MR_MONITOR[8625]: <MRMON153> Controller ID: 0 Battery relearn completed Aug 13 16:32:15 AVATPCKVS41N05 MR_MONITOR[8625]: <MRMON155> Controller ID: 0 Battery relearn pending: Battery is under charge Aug 13 16:44:10 AVATPCKVS41N05 MR_MONITOR[8625]: <MRMON151> Controller ID: 0 Battery relearn started Aug 13 16:45:15 AVATPCKVS41N05 MR_MONITOR[8625]: <MRMON152> Controller ID: 0 Battery relearn in progress Aug 13 16:48:30 AVATPCKVS41N05 MR_MONITOR[8625]: <MRMON154> Controller ID: 0 Battery relearn timed out 5.

Example 2: Aug 26 01:30:23 AVATPCKVS41N05 sudo: root : TTY=pts/0 ; PWD=/root ; USER=root ; COMMAND=/opt/MegaRAID/CmdTool2/CmdTool2 -AdpBbuCmd -BbuLearn -a0 Aug 26 01:31:12 AVATPCKVS41N05 MR_MONITOR[8625]: <MRMON155> Controller ID: 0 Battery relearn pending: Battery is under charge Aug 26 16:44:10 AVATPCKVS41N05 MR_MONITOR[8625]: <MRMON151> Controller ID: 0 Battery relearn started Aug 26 16:45:15 AVATPCKVS41N05 MR_MONITOR[8625]: <MRMON152> Controller ID: 0 Battery relearn in progress Aug 26 16:48:30 AVATPCKVS41N05 MR_MONITOR[8625]: <MRMON154> Controller ID: 0 Battery relearn timed out Here, the "relearn" timed out. 8. Recheck the battery status: CmdTool2 -AdpBbuCmd -GetBbuStatus -a0 If the status is OK and there is no timeout (as seen below), no further action is required. BBU status for Adapter: 0BatteryType: CVPM02 Voltage: 9563 mV Current: 0 mA Temperature: 30 CBBU Firmware Status: Charging Status : None Voltage : OK Temperature : OK Learn Cycle Requested : No Learn Cycle Active : No Learn Cycle Status : OK Learn Cycle Timeout : No I2c Errors Detected : No ... If the issue remains as seen below, Create a Service Request providing the output above to determine if a node replacement is required.
