If your system does not have onboard keymanager, NSE or NVE configured, complete the steps in this
section.

6. From the LOADER prompt, enter the

boot_ontap

command.

If you see…

Then…

The login prompt

Go to the next Step.

Waiting for giveback…

a. Log into the partner controller.

b. Confirm the target controller is ready for giveback with the

storage failover show

command.

7. Connect the console cable to the partner controller.

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 - FAS500f

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.

1. 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

Restore NVE or NSE when

Onboard Key Manager is enabled

◦

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

Restore NSE/NVE on systems running ONTAP 9.6

and later

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:
