270 Implementing the IBM Storwize V7000 with IBM Spectrum Virtualize V8.2.1
HyperSwap volume configuration is possible only after the IBM Spectrum Virtualize system is 
configured in HyperSwap topology. After this topology change, the GUI presents an option to 
create a HyperSwap volume and creates them by using the mkvolume command instead of the 
usual mkvdisk command. The GUI continues to uses the mkvdisk command when all other 
classes of volumes are created.
From the perspective of a host or a storage administrator, a HyperSwap volume is a single 
entity; however, it is realized by using four volumes and a set of FlashCopy maps and a 
remote copy relationship (see Figure 7-23).
Figure 7-23   What makes up a HyperSwap Volume 
The GUI simplifies the HyperSwap volume creation process by asking about required volume 
parameters only, and automatically configuring all the underlying volumes, FlashCopy maps, 
and volume replications relationships. 
An example of a HyperSwap volume configuration is shown in Figure 7-24 on page 271.
Note: It is still possible to create HyperSwap volumes in V7.5, as described in this IBM 
Support white paper.
