text: 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.
