I have FAS 3240 Cluster and one of the controller is giving me messages that
Netappctrl1 monitor.nvramLowBatteries:alert]: NVRAM batteries are dangerously low.
Netappctrl1 monitor.nvramLowBatteries.notice:notice]: If the NVRAM batteries are "" dangerously low, the system shuts down automatically "" every 24 hours to encourage you to replace them. "" If you reboot the system it will run for another "" 24 hours before shutting down.
Netappctrl1 monitor.shutdown.nvramLowBatteries.pending:warning]: NVRAM batteries are dangerously low. Halting system in 24 hours. Replace the batteries immediately!
I completely understand that I will have to replace the NVRAM battery and I have also refered the Kb article on Netapp which is failry easy to understand except a single thing which I want to confirm
Just prepare spare NVMEM battery which is supplied by NetApp, and follow instructions. Part number is X3148A-R6.
NVMEM battery module is not a bunch of battery cells. It has intelligent circuit inside and controls itself. Do not use any other battery cells or modules. Use of insufficient battery may break your controller.
from the sp run system battery show and confirm you are on the latest firmware release. If the system is running for 4 years and you havent updated the firmware there is a chance you could be hitting hte bug
