662 Implementing the IBM Storwize V7000 with IBM Spectrum Virtualize V8.2.1
To declare an MDisk as self-encrypting, select Externally encrypted when adding external 
storage in the Assign Storage view, as shown in Figure 12-77.
Figure 12-77   Declaring MDisk as externally encrypted
IBM Spectrum Virtualize products can detect that an MDisk is self-encrypting by using the 
SCSI Inquiry page C2. MDisks that are provided by other IBM Spectrum Virtualize products 
report this page correctly. For these MDisks, the Externally encrypted option that is shown in 
Figure 12-77 is not selected. However, when added, they are still considered as 
self-encrypting.
Note: You can override the external encryption setting of a detected MDisk as 
self-encrypting and configure it as unencrypted by using the CLI command chmdisk 
-encrypt no. However, only do so if you plan to decrypt the data on the backend or if the 
backend uses inadequate data encryption.
