272 Implementing the IBM Storwize V7000 with IBM Spectrum Virtualize V8.2.1
A summary (lower left of the creation window) lists the entities that are instantiated when the 
Create option is selected. As shown in Figure 7-24 on page 271, a single volume is created, 
with volume copies in sites site1 and site2. This volume is in an active-active (Metro Mirror) 
relationship with extra resilience provided by two change volumes.
The command that is issued to create this volume is shown in Figure 7-25. 
Figure 7-25   Example mkvolume command
After the volume is created, it is visible in the volumes list, as shown in Figure 7-26

The Pool column shows the value Multiple, which indicates that a volume is a HyperSwap 
volume. A volume copy at each site is visible and the change volumes that are used by the 
technology are not displayed in this GUI view.
A single mkvolume command allows creation of a HyperSwap volume. Up to IBM Spectrum 
Virtualize V7.5, this process required careful planning and the use of the following sequence 
of commands:
/SM590000mkvdisk master_vdisk
/SM590000mkvdisk aux_vdisk
/SM590000mkvdisk master_change_volume
/SM590000mkvdisk aux_change_volume
/SM590000mkrcrelationship –activeactive
/SM590000chrcrelationship -masterchange
/SM590000chrcrelationship -auxchange
/SM590000addvdiskacces
