A volume is reported as encrypted only if all the volume copies are encrypted, as shown in 
Figure 12-80.

When creating volumes, make sure to select encrypted pools to create encrypted volumes, as 
shown in Figure 12-81.

You cannot change an existing unencrypted volume to an encrypted version of itself 
dynamically. However, this conversion is possible by using two migration options:
/SM590000Migrate a volume to an encrypted pool or child pool.
/SM590000Mirror a volume to an encrypted pool or child pool and delete the unencrypted copy.
For more information about these methods, see Chapter 7, “Volumes” on page 241.
