text: **7.8.2 Creating a volume**
  
  The use of the**mkvdisk**command creates sequential, striped, or image mode volumes. When 
  they are mapped to a host object, these objects are seen as disk drives on which the host can 
  perform I/O operations. 
  
  **Creating an image mode disk:**If you do not specify the**-size**parameter when you create 
  an image mode disk, the entire MDisk capacity is used. 
  
  You must know the following information before you start to create the volume: 
  
  (cid:2) In which storage pool the volume will have its extents 
  (cid:2) From which I/O Group the volume will be accessed 
  (cid:2) Which IBM Spectrum Virtualize node will be the preferred node for the volume 
  (cid:2) Size of the volume 
  (cid:2) Name of the volume 
  (cid:2) Type of the volume 
  (cid:2) Whether this volume is to be managed by IBM Easy Tier to optimize its performance
