Issue

  • Post motherboard (PCM) replacement of the models in the Applies to section, the following errors occur during boot:

Apr 27 08:31:18 [Node1:nvmem.battery.unread:EMERGENCY]: The NVMEM battery state cannot be determined because the 'Bat Initial FCC' sensor is unreadable. To prevent data loss, the system will shut down in 5 minutes.
Apr 27 08:31:18 Power outage protection flash de-staging: 28 cycles
 
WARNING:  The battery is unfit to retain data during a power
          outage.  This is likely because the battery is
          discharged but could be due to other temporary
          conditions.
          When the battery is ready, the boot process will
          complete and services will be engaged.
          To override this delay, press 'c' followed by 'Enter'
Apr 27 08:32:18 [Node1:callhome.battery.failure:EMERGENCY]: Call home for BATTERY ('Bat Initial FCC' unreadable) CRITICAL.
Apr 27 08:32:19 [Node1:nvmem.battery.packInvalid:EMERGENCY]: The incorrect NVMEM battery is installed. Expected part number is 271-00045. To prevent data loss, the system will shut down in 5 minutes.
Apr 27 08:32:49 [Node1:callhome.battery.failure:EMERGENCY]: Call home for BATTERY (invalid pack) CRITICAL.

or

WARNING:  The battery is experiencing a critical failure:
           - Invalid battery pack is detected
          Without a working battery, the system cannot retain data
          during a power outage, which can result in data loss.
          Power down the system and verify that the battery is
          properly installed.
          To ignore this failure and boot the system in a mode
          where data loss might occur, press 'c' followed by 'Enter'

  • The node then proceeds to shut down.
