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.
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.
Step 1. Obtain replacement license keys by contacting Lenovo technical support.
Note: The new license keys that you require are NOT auto-generated. You should contact Lenovo
technical support.
Install each license key: system license add -license-code license-key, license-key...

Step 3. Remove the old licenses, if desired:

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 k k e e y y _ _ m m a a n n a a g g e e r r setup wizard and to set the
FIPS and/or data authentication keys on the disks.
Verifying LIFs and registering the serial number
Before returning the replacement controller to service, you should verify that the LIFs are on their home
ports, and register the serial number of the replacement controller if AutoSupport is enabled, and reset
automatic giveback.
Verify that the logical interfaces are reporting to their home server and ports: network interface
Step 1.

If any LIFs are listed as false , revert them to their home ports: network interface revert *
Step 2. Register the system serial number with Lenovo Support.
