text: **7.8.4 Creating a volume in image mode**
  
  Use image mode volume to bring a non-virtualized disk (for example, from a pre-virtualization 
  environment) under the control of the IBM Spectrum Virtualize system. After it is managed by 
  the system, you can migrate the volume to the standard managed disk. 
  
  When an image mode volume is created, it directly maps to the thus far unmanaged MDisk 
  from which it is created. Therefore, except for a thin-provisioned image mode volume, the 
  volume’s LBA x equals MDisk LBA x. 
  
  **Size:**An image mode volume must be at least 512 bytes (the capacity cannot be 0) and 
  always occupies at least one extent.
