text: **7.1.2 Volume characteristics**
  
  Volumes have the following characteristics or attributes: 
  
  (cid:2) Volumes can be configured as managed or in image mode. 
  
  (cid:2) Volumes can have extents allocated in striped or sequential mode. 
  
  (cid:2) Volumes can be created as fully allocated or thin-provisioned. A conversion from a fully 
  allocated to a thin-provisioned volume and vice versa can be done at run time. 
  
  (cid:2) Volumes can be configured to have single data copy, or be mirrored to make them 
  
  resistant to disk subsystem failures or to improve the read performance.
