text: A Storwize family system is in the storage layer by default, but the layer can be changed. For 
  example, you might want to change a Storwize V7000 to a replication layer if you want to 
  virtualize other Storwize systems. 
  
  **Note:**Before you change the system layer, the following conditions must be met: 
  
  (cid:2) No host object can be configured with worldwide port names (WWPNs) from a Storwize 
  family system. 
  
  (cid:2) No system partnerships can be defined. 
  
  (cid:2) No Storwize family system can be visible on the SAN fabric. 
  
  The layer can be changed during normal host I/O. 
  
  In your IBM Storwize system, use the**lssystem**command to check the current system layer, 
  as shown in Example 11-2.
