text: 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. 
  
  **Note:**It is still possible to create HyperSwap volumes in V7.5, as described in this IBM 
  Support white paper. 
  
  For more information, see IBM Storwize V7000, Spectrum Virtualize, HyperSwap, and 
  VMware Implementation, SG24-8317.

  page. 
  
  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).
