Issue

  • The system is running a fixed version for Bug 1073579, but still seeing the same symptoms.
  • FPGA version can be found in the "sysconfig -a" command via console, or examining " SYSCONFIG-A " in ASUP:

Example:

slot 6: NVRAM (NVRAM 10)
Revision:           B0
Serial Number:      031945002448
DIMM Size:          16384 MB
Memory Size:        32768 MB
Battery Status:     Battery sufficiently charged
Running Firmware:   1.2.0    

  • The 'current is below normal (-50 mA)' warning message is followed by a 'current is normal' message within a minute in the EMS logs:

Example:

node-04 ERROR nvram.battery.current.low.warn: The NVRAM battery current is below normal (-50 mA). To prevent data loss, the system will shut down in 24 hours.
node-04 INFORMATIONAL nvram.battery.current.normal: The NVRAM battery current is normal.
node-04 ALERT callhome.battery.warning: Call home for BATTERY (current low) WARNING.

  •  The Service Processor (SP) system event log displays the following information:
