text: key of the pool or child pool they belong to by default. You can override this default 
  by manually configuring the MDisk as not self-encrypting. 
  
  (cid:129) Data encryption keys are stored in secure memory. 
  
  (cid:129) During cluster internal communication, data encryption keys are encrypted with the 
  master access key. 
  
  (cid:129) Data encryption keys cannot be viewed. 
  
  (cid:129) Data encryption keys cannot be changed. 
  
  (cid:129) When an encrypted object is deleted, its data encryption key is discarded (*secure*
  *erase*). 
  
  **Important:**If all master access key copies are lost and the system must cold restart, all 
  encrypted data is gone. No method exists, even for IBM, to decrypt the data without the 
  keys. If encryption is enabled and the system cannot access the master access key, all 
  SAS hardware is offline, including unencrypted arrays.
