Step 7.
If you disabled automatic takeover on reboot, enable it from the healthy controller:
modify -node replacement-node-name -onreboot true
Installing licenses for the replacement controller in ONTAP
You must install new licenses for the replacement controller if the degraded controller was using ONTAP
features that require a standard (controller-locked) license. For features with standard licenses, each
controller in the cluster should have its own key for the feature.
About this task
Until you install license keys, features requiring standard licenses continue to be available to the replacement
controller. However, if the degraded controller was the only controller in the cluster with a license for the
feature, no configuration changes to the feature are allowed. Also, using unlicensed features on the controller
might put you out of compliance with your license agreement, so you should install the replacement license
key or keys on the replacement controller as soon as possible.
The licenses keys must be in the 28-character format.
You have a 90-day grace period in which to install the license keys. After the grace period, all old licenses are
invalidated. After a valid license key is installed, you have 24 hours to install all of the keys before the grace
period ends.
Note: The new license keys that you require are automatically generated and sent to the email address on
file. If you did not receive the email with the license keys within 30 days, contact technical support.
Step 1.
If you need to retrieve the license keys, obtain the replacement license keys on
Demand. For details, refer to

If the list looks correct, remove the unused licenses:
Restoring Storage Encryption functionality
After replacing the controller module or NVRAM module for a storage system that you previously configured
to use Storage Encryption, you must perform additional steps to ensure uninterrupted Storage Encryption
functionality. You can skip this task on storage systems that do not have Storage Encryption enabled.
Step 1.
Restore Storage Encryption functionality by running the
FIPS and/or data authentication keys on the disks.
Verifying LIFs
Before returning the replacement controller to service, you should verify that the LIFs are on their home ports
and reset automatic giveback.
Step 1.
Verify that the logical interfaces are reporting to their home controller and ports:
show -is-home false
If any LIFs are listed as false , revert them to their home ports:
Step 2.
If automatic giveback was disabled, reenable it:
