text: The software update test utility can be downloaded in advance of the update process. 
  Alternately, it can be downloaded and run directly during the software update, as guided by 
  the update wizard. 
  
  You can run the utility multiple times on the same IBM Storwize V7000 system to perform a 
  readiness check-in preparation for a software update. Run this utility for a final time 
  immediately before you apply the software update to ensure that there were no new releases 
  of the utility since it was originally downloaded.
