text: **Initial configuration**
  
  This chapter describes the initial configuration of the IBM Storwize V7000 system. It provides 
  step-by-step instructions about how to create the cluster, define its basic settings, and add 
  nodes and optional expansion enclosures. 
  
  Other features, such as user authentication, secure communications, and local port masking, 
  are also covered. These features are optional and do not need to be configured during the 
  initial configuration.
