Chapter 12. Encryption 663
To check whether an MDisk was detected or declared as self-encrypting, click Pools → 
MDisk by Pools and verify the information in the Encryption column, as shown in 
Figure 12-78. 
Figure 12-78   MDisk self-encryption state
The value that is shown in the Encryption column shows the property of objects in respective 
rows. That means that in the configuration that is shown in Figure 12-78, Pool1 is encrypted, 
so every volume created from this pool is encrypted. However, that pool is formed by two 
MDisks, out of which one is self-encrypting and one is not. Therefore, a value of No next to 
mdisk2 does not imply that encryption of Pool1 is in any way compromised. It only indicates 
that encryption of the data placed on mdisk2 is done by using software encryption. Data that 
is placed on mdisk1 is encrypted by the back-end storage that is providing these MDisks.
12.8.5  Encrypted volumes
For more information about how to create and manage volumes, see Chapter 7, “Volumes” on 
page 241. The encryption status of a volume depends on the pool encryption status. Volumes 
that are created in an encrypted pool are automatically encrypted.
You can modify Volumes view to show if the volume is encrypted. Click Volumes → Volumes. 
Then, click Actions → Customize Columns → Encryption to customize the view to show 
volumes encryption status, as shown in Figure 12-79.

Note: You can change the self-encrypting attribute of an MDisk that is unmanaged or 
member of an unencrypted pool. However, you cannot change the self-encrypting attribute 
of an MDisk after it is added to an encrypted pool.
