How to troubleshoot "Insufficient learned battery capacity" alerts on E-Series arrays
Applies to
NetApp E-Series
Description
- Currently E-series systems used "Smart Batteries".
- This is a type of battery based on newer technologies that utilize different chemical compounds and provide complex support circuitry to provide estimated usage times
- This type of battery can typically be exposed to a controlled discharge and recharge (learn cycle) which will restore the power capacity and extend the useful life of the battery
- This type of battery can be used as long as it can be charged to a level sufficient to protect cache memory for a minimum required duration
- When the Learn cycle finds issues during the process of discharge/charge of the battery, the system will trigger an
Insufficient learned battery capacity
alert and in theMajor-Event.log
anIncomplete battery learn cycle
message will be displayed
