  • NetApp Volume Encryption (NVE)
  • On Board Key Manager (OKM)

Answer

The Onboard Key Manager is a built-in tool that serves authentication keys to nodes from the same storage system as your data. When using OKM you do not need an external key manager to generate encryption keys – the keys are generated automatically – all you need to do is run “security key-manager onboard enable”


Step 1:
 
Run security key-manager onboard enable command

cluster2::> security key-manager onboard enable

Enter the cluster-wide passphrase for the Onboard Key Manager:

Re-enter the cluster-wide passphrase:
After configuring the Onboard Key Manager, save the encrypted configuration data in a safe location so that you can use it if you need to perform a manual recovery operation. To view the data, use the "security key-manager onboard show-back up" command.

The onboard passphrase MUST be 32 to 256 ASCII-range characters long.

Step 2:
 
Check the Keys

cluster2::> security key-manager key query -node cluster2-01

Node: cluster2-01
Vserver: cluster2
Key Manager: onboard
Key Manager Type: OKM
