RAIDx_Super_Cap/Battery Battery failed---PCIeslot:x
Cause Analysis
Array card battery fault alarm reporting mechanism: The array card firmware pushes the fault information to the BMC, The BMC converts and generates SEL logs, then synchronizes and reports them to the HDM Web interface.
After this alarm is triggered, it will be automatically cleared in the next polling cycle. Analysis has determined that it was a false alarm triggered by the array card firmware, and the solution is to add debounce logic on the BMC side to avoid such false reports.
