Check NVE or NSE on systems running ONTAP 9.6 and later
Before shutting down the impaired node, 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 configured 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.
2. Verify whether NSE is configured:
storage encryption disk show
◦
If the command output list the drive details with Mode & Key ID information, NSE is configured and you
need to verify the NSE configuration.
◦
If no disks are shown, NSE is not configured.
◦
If NVE and NSE are not configured, it’s safe to shut down the impaired node.
Verify NVE configuration
1. Display the key IDs of the authentication keys that are stored on the key management servers:
security
key-manager query
◦ If the
Key Manager
type displays
external
and the
Restored
column displays
yes
, it’s safe to shut
down the impaired node.
◦ If the Key Manager type displays onboard and the Restored column displays yes , you need to
complete some additional steps.
◦ If the
Key Manager
type displays
external
and the
Restored
column displays anything other than
yes
, you need to complete some additional steps.
◦ If the
Key Manager
type displays
onboard
and the
Restored
column displays anything other than
yes , you need to complete some additional steps.
2. If the
Key Manager
type displays
onboard
and the
Restored
column displays
yes
, manually backup
the OKM information:
a. Go to advanced privilege mode and enter
y
when prompted to continue:
set -priv advanced
b. Enter the command to display the key management information:
security key-manager onboard
show-backup
c. Copy the contents of the backup information to a separate file or your log file. You’ll need it in disaster
scenarios where you might need to manually recover OKM.
d. Return to admin mode:
set -priv admin
e. Shut down the impaired node.
3. If the
Key Manager
type displays
external
and the
Restored
column displays anything other than
yes
:
a. Restore the external key management authentication keys to all nodes in the cluster:
security key-
manager external restore
