  The following section describes how to add or remove expansion enclosure to or from your 
  IBM Storwize V7000 system. 
  
  **Adding an enclosure**
  After the expansion enclosure is properly attached and powered on, complete the following 
  steps to activate it in the system: 
  
  1. 
  
  In the System pane that is available from the Monitoring menu, select**SAS Chain View**. 
  Only correctly attached and powered on enclosures appear in the window, as shown in 
  Figure 5-88. The new enclosure is showing as unmanaged, which means it is not currently 
  part of the system.
