792 Implementing the IBM Storwize V5000 Gen2 with IBM Spectrum Virtualize V8.1
Note that the value shown in the Encryption column shows the property of objects in
respective rows. That means that in the configuration shown in Figure 13-70, Pool1 is
encrypted, so every volume created from this pool will be encrypted. However, that pool is
backed by three MDisks, out of which two are self-encrypting and one is not. Therefore, a
value of “no” next to mdisk7 does not imply that encryption of Pool1 is in any way
compromised.
It only indicates that encryption of the data placed on mdisk7 will be done via software
encryption, while data placed on mdisk2 and mdisk8 will be encrypted by the back-end
storage providing these MDisks.
13.8.5 Encrypted volumes
See Chapter 6, “Volume configuration” on page 287 for instructions on how to create and
manage volumes. 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 given 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 13-71.
Figure 13-71 Volume view customization
Note that a volume is reported as encrypted only if all the volume copies are encrypted, as
shown in Figure 13-72.

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