You don’t need to be an expert to perform a basic vSAN troubleshooting and many problems could be easily resolved without the need to open a case. All you need is a good process.

Here is a simple procedure that might be useful when you find out you have a problem

• • • • • • • validates that objects can be created based on policies and available resources.
