Hello MarcLaflamme, With an EMC CX3san it is best to monitor the system using Navisphere/ Ushpere. I have seen the errors that you are having before and it was due to open manage issue with it not correctly interacting with your CX3 san. Please let us know if you have any other questions.
Cross posting from en.community.dell.com/.../20002862 as requested by Dell-Shivendra K. We are receiving odd errors being sent via Open Manage Essentials regarding our CX3 yet when looking on the CX3 directly through Navisphere, there's nothing wrong. Just trying to figure out what's causing these bogus errors.
