text: If your system is within warranty or if you have a hardware maintenance agreement, configure 
  your IBM Storwize V7000 system to send email events directly to IBM if an issue that requires 
  hardware replacement is detected. This mechanism is known as*Call Home*. When this event 
  is received, IBM automatically opens a problem report and, if appropriate, contacts you to 
  help resolve the reported problem. 
  
  **Important:**If you set up Call Home to IBM, ensure that the contact details that you 
  configure are correct and kept updated. Personnel changes can cause delays in IBM 
  making contact. 
  
  Cloud Call Home is specifically designed to work with new service teams and improves 
  connectivity and ultimately should improve customer support. 
  
  **Note:**If the customer does not want to open the firewall, Cloud Call Home does not work 
  and the customer can disable Cloud Call Home. Call Home is used instead.
