290 Implementing the IBM Storwize V7000 with IBM Spectrum Virtualize V8.2.1
When you are ready to create your striped volume, use the mkvdisk command. The command 
shown in Example 7-2 creates a 10 gigabyte (GB) striped volume with volume ID 8 within the 
storage pool Pool0 and assigns it to the I/O group io_grp0. Its preferred node is node 1.
Example 7-2   The mkvdisk command
IBM_Storwize:ITSO:superuser>mkvdisk -mdiskgrp Pool0 -iogrp io_grp0 -size 10 -unit gb -name 
Tiger
Virtual Disk, id [8], successfully created
To verify the results, use the lsvdisk command providing the volume ID as the command 
parameter, as shown in Example 7-3.
