Option 2: Checking 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:
volume show -is-encrypted true
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:
storage encryption disk show
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.
