## 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).

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: 

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). 

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.
