text: However, if you want to create encrypted child pools from an unencrypted storage pool that 
  contains a mix of internal arrays and external MDisks, the following restrictions apply: 
  
  (cid:2) The parent pool must not contain any unencrypted internal arrays. If any unencrypted 
  
  internal array is in the unencrypted pool, when you try to create a child pool and select the 
  option to set as encrypted, it is created as unencrypted. 
  
  (cid:2) All V7000 Storwize control enclosures in the system must support software encryption and 
  have the encryption license activated. 
  
  **Note:**An encrypted child pool that is created from an unencrypted parent storage pool 
  reports as unencrypted if the parent pool contains any unencrypted internal arrays. 
  Remove these arrays to ensure that the child pool is fully encrypted. 
  
  If you modify Pools view, you see the encryption status of child pools, as shown in 
  Figure 12-73. The example shows an encrypted child pool with non-encrypted parent pool.
