  **4.7.3 Changing the system topology to HyperSwap**
  
  The IBM HyperSwap function is a high availability feature that provides dual-site, active-active 
  access to a volume. You can create an IBM HyperSwap topology system configuration where 
  each I/O group in the system is physically on a different site. When used with HyperSwap 
  volumes, these configurations can be used to maintain access to data on the system if 
  site-wide outages occur. 
  
  To change the system topology to HyperSwap, complete the following steps: 
  
  In the GUI, click**Monitoring**→**System**. Then, click**System Actions**and choose**Modify**
  **System Topology**, as shown in Figure 4-45.
