After you change the vSAN configuration, vCenter Server performs validation checks for vSAN configuration. Validation checks are also performed as a part of a host synchronization process. If vCenter Server detects any configuration problems, it displays error messages.

Problem

Error messages indicate that vCenter Server has detected a problem with vSAN configuration.

Solution

Use the following methods to fix vSAN configuration problems.
