text: **Modify encryption**
  Select**Modify Encryption**to modify the encryption setting for the MDisk. This option is 
  available only when encryption is enabled. 
  
  If the external MDisk is already encrypted by the external storage system, change the 
  encryption state of the MDisk to**Externally encrypted**. This setting stops the system from 
  encrypting the MDisk again if the MDisk is part of an encrypted storage pool. 
  
  For information about encryption, encrypted storage pools, and self-encrypting MDisks, see 
  Chapter 12, “Encryption” on page 603. 
  
  To perform this task with CLI, use**chmdisk**. See Example 6-27.
