Step 3: Replace the NVMEM battery
Remove the failed NVMEM battery from the system and replace it with a new NVMEM battery.
Steps
1. If you are not already grounded, properly ground yourself.
2. Check the NVMEM LED:
◦ Check the NVRAM LED identified by the NV icon.
NV
The NVRAM LED blinks while destaging contents to the flash memory
when you halt the system. After the destage is complete, the LED turns
off.
▪ If power is lost without a clean shutdown, the NVMEM LED flashes until the destage is
complete, and then the LED turns off.
▪ If the LED is on and power is on, unwritten data is stored on NVMEM.
This typically occurs during an uncontrolled shutdown after ONTAP has successfully
booted.
3. Locate the NVMEM battery in the controller module.
