text: Figure 6-41 Adding internal storage to a pool by using the Advanced option 
  
  To return to the default settings, click the**Refresh**button next to the pool capacity. To create 
  and assign the arrays, click**Assign**. 
  
  Unlike automatic assignment, custom internal configuration does not create multiple arrays. 
  You must create each array separately. 
  
  As with automatic assignment, the system does not allow you to add significantly different 
  arrays to an existing and populated pool. The goal is to achieve balance across MDisks inside 
  one pool. You can still add any array of any configuration to an existing pool by using the CLI. 
  
  **Note:**When Internal Custom configuration is performed, spare drives are not assigned 
  when traditional RAID arrays are created. You need to set them up manually.
