21.After all the nodes are updated, you must confirm the update to complete the process. The 
confirmation restarts each node in order, which takes about 30 minutes to complete. 
The update is complete.
13.5  Health checker feature
The IBM Spectrum Control health checker feature runs in the IBM Cloud. Based on the 
weekly call home inventory reporting, it proactively creates recommendations. These 
recommendations are provided on the IBM Call Home Web, which is found at ibm.com. Click 
Support → My support → Call Home Web (see Figure 13-32).

Another feature is Critical Fix Notification function, which enables IBM to warn Storwize 
V7000 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 connected to the internet. 
Consider the following information about this function:
/SM590000It warns users only about critical fixes, and does not warn them that they are running a 
previous version of the software.
/SM590000It works only if the browser also has access to the internet IBM Storwize V7000 and IBM 
SAN Volume Controller systems themselves do not need to be connected to the internet.
/SM590000The function cannot be disabled. Each time it displays a warning, it must be acknowledged 
(with the option to not warn the user again for that issue).
The decision about what is 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 continue to review information about new code levels to 
determine whether they must update, even without a critical fix notification.
