8. Give back the controller using the 

storage failover giveback -fromnode local

 command.

9. At the cluster prompt, check the logical interfaces with the 

net int -is-home false

 command.

If any interfaces are listed as "false", revert those interfaces back to their home port using the 

net int

revert

 command.

10. Move the console cable to the repaired controller and run the 

version -v

 command to check the ONTAP

versions.

11. Restore automatic giveback if you disabled it by using the 

storage failover modify -node local

-auto-giveback true

 command.

Restore OKM, NSE, and NVE as needed - AFF A200

Once environment variables are checked, you must complete steps specific to systems
that have Onboard Key Manager (OKM), NetApp Storage Encryption (NSE) or NetApp
Volume Encryption (NVE) enabled.

Determine which section you should use to restore your OKM, NSE, or NVE configurations:

If NSE or NVE are enabled along with Onboard Key Manager you must restore settings you captured at the
beginning of this procedure.

• If NSE or NVE are enabled and Onboard Key Manager is enabled, go to 

Option 1: Restore NVE or NSE

when Onboard Key Manager is enabled

.

• If NSE or NVE are enabled for ONATP 9.5, go to 

Option 2: Restore NSE/NVE on systems running ONTAP

9.5 and earlier

.

• If NSE or NVE are enabled for ONTAP 9.6, go to 

Option 3: Restore NSE/NVE on systems running ONTAP

9.6 and later

.

Option 1: Restore NVE or NSE when Onboard Key Manager is enabled

Steps

1. Connect the console cable to the target controller.

2. Use the 

boot_ontap

 command at the LOADER prompt to boot the controller.

3. Check the console output:

If the console
displays…

Then…

The LOADER prompt

Boot the controller to the boot menu: 

boot_ontap menu

Waiting for giveback…

a. Enter 

Ctrl-C

 at the prompt

b. At the message: Do you wish to halt this controller rather than wait [y/n]? ,

enter: 

y

c. At the LOADER prompt, enter the 

boot_ontap menu

 command.

4. At the Boot Menu, enter the hidden command,
