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
Check NVE or NSE on systems running ONTAP 9.6 and later
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:
