text: The installation and use of this utility is nondisruptive, and does not require restart of any IBM 
  Storwize V7000 nodes. Therefore, there is no interruption to host I/O. The utility is only 
  installed on the current configuration node. 
  
  System administrators must continue to check whether the version of code that they plan to 
  install is the latest version. For the most current information, see this website. 
  
  This utility is intended to supplement rather than duplicate the tests that are performed by the 
  IBM Spectrum Virtualize update procedure (for example, checking for unfixed errors in the 
  error log). 
  
  Concurrent software update of all components is supported through the standard Ethernet 
  management interfaces. However, most of the configuration tasks are restricted during the 
  update process.
