Issue

  • Alert message reported. Example:
    [Message: nvmem.battery.FET.off: The NVMEM battery charge FET is off. To prevent data loss, the system will shut down in 24 hours.]
    [Description: This message occurs when the NVMEM battery charge field-effect transistor (FET) is off. If this issue is not resolved within the specified time, the system shuts down to prevent data loss.]
    [Corrective Action: Shut down the system and power-cycle the controller. If the charge FET remains off, replace the NVMEM battery. If the problem persists, replace the controller module.]

  • ONTAP battery sensors output correct. Example:
    [::> system node environment sensors show -name "Bat Present"|"Bat Volt"]
    [Node Sensor State Value/Units Crit-Low Warn-Low Warn-Hi Crit-Hi]
    [---- --------------------- ------ ----------- -------- -------- ------- -------]
    [Node-n01]
    [ Bat Present normal]
    [ PRESENT]
    [ Bat Volt normal]
    [ 7700 mV 5500 5600 8500 8600]
    [Node-n02]
    [ Bat Present normal]
    [ PRESENT]
