3. Check the version of ONTAP the system is running on the impaired controller if up, or on the partner
controller if the impaired controller is down, using the
◦ If <lno-DARE> or <1Ono-DARE> is displayed in the command output, the system does not
support NVE, proceed to shut down the controller.
◦ If <lno-DARE> is not displayed in the command output, and the system is running ONTAP 9.6 or
later, go to the next section.
4. If the impaired controller is part of an HA configuration, disable automatic giveback from the healthy
controller:
storage failover modify -node local -auto-giveback false
failover modify -node local -auto-giveback-after-panic false

Before shutting down the impaired controller, you need to verify whether the system has either NetApp
Volume Encryption (NVE) or NetApp Storage Encryption (NSE) enabled. If so, you need to verify the
configuration.
1. Verify whether NVE is in use for any volumes in the cluster:
If any volumes are listed in the output, NVE is configured and you need to verify the NVE
configuration. If no volumes are listed, check whether NSE is configured and in use.
2. Verify whether NSE is configured and in use:
◦ If the command output lists the drive details with Mode & Key ID information, NSE is configured
and you need to verify the NSE configuration and in use.
◦ If no disks are shown, NSE is not configured.
◦ If NVE and NSE are not configured, no drives are protected with NSE keys, it's safe to shut down
the impaired controller.
== Verify NVE configuration
1. Display the key IDs of the authentication keys that are stored on the key management servers:

are KMIP, AKV, and GCP. The process for confirming these types is the same as
