Step 1.
Check the NVMEM LED:
•
NV
Attention: 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.
Step 2.
Locate the NVMEM battery in the controller module.
