text: An alias string can also be associated with an iSCSI node. The alias enables an organization 
  to associate a string with the iSCSI name. However, the alias string is not a substitute for the 
  iSCSI name. 
  
  **Note:**The cluster name and node name form part of the IQN. Changing any of them might 
  require reconfiguration of all iSCSI nodes that communicate with the Storwize V7000.
