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:
1. In the GUI, click Monitoring → System. Then, click System Actions and choose Modify 
System Topology, as shown in Figure 4-45.
