3. Move the boot media to the new controller module, align the edges of the boot media with the socket
housing, and then gently push it into the socket.
4. Check the boot media to make sure that it is seated squarely and completely in the socket.
If necessary, remove the boot media and reseat it into the socket.
5. Push the boot media down to engage the locking button on the boot media housing.
Step 3: Move the NVMEM battery
To move the NVMEM battery from the old controller module to the new controller module, you must perform a
specific sequence of steps.
1. Check the NVMEM LED:
◦
If your system is in an HA configuration, go to the next step.
◦
If your system is in a stand-alone configuration, cleanly shut down the controller module, and then
check the NVRAM LED identified by the NV icon.
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.
2. Open the CPU air duct and locate the NVMEM battery.
