Thanks for the responses.
I wound up re-creating the mirrors on our system and we are now back to our original working state.
I'm waiting to hear back from our EMC tech about the application profiles.
I did check the IP's of the Centera device, and we could not reach them during the outage (we confirmed the IP's were correct with the EMC tech)
Unfortunately, the App Log events from the outage were overwritten when the mirror was rebuilt.
I will keep you posted.
