13.5 Health checker feature The IBM Spectrum Control health checker feature runs in IBM Cloud. Based on the weekly  call home inventory reporting, it proactively creates recommendations. These  recommendations are provided at IBM Call Home Web, which you can access by selecting  Support My support Call Home Web  (Figure 13-26). For a video guide about how to set up and use IBM Call Home Web, go to the following  website: https://www.youtube.com/watch?v=7G9rqk8NXPA Another feature is the  Critical Fix Notification  function, which enables IBM to warn  IBM Spectrum Virtualize users that a critical issue exists in the level of code that they are  using. The system notifies users when they log on to the GUI by using a web browser that is  connected to the internet.  Consider the following information about this function: The decision about what a  critical  fix is subjective and requires judgment, which is exercised  by the development team. As a result, clients might still encounter bugs in code that were not  deemed critical. They should continue to review information about new code levels to  determine whether they should update even without a critical fix notification. 730  Implementing the IBM System Storage SAN Volume Controller with IBM Spectrum Virtualize V8.2.1 GLYPH<SM590000> It warns users only about critical fixes, and does not warn them that they are running a  previous version of the software. GLYPH<SM590000> It works only if the browser also has access to the internet. The IBM Storwize V7000 and  IBM SAN Volume Controller systems themselves do not need to be connected to the  internet. GLYPH<SM590000> The function cannot be disabled. Each time that is displays a warning, it must be  acknowledged (with the option to not warn the user again for that issue).
