Looks like events from the EMC PowerPath storage subsystem which are fed to vCenter and then surfaced in our MP.
Our support team would be able to tell you if we see many customers with such events; and also could guide you to suppressing them in our MP (if you decide they are not relevant)
However to get to the root cause you'd need to investigate the storage subsystem, it's definitely throwing this warning event - probably something you should investigate with EMC support too.
Hope that helps!
