I'm entirely sure what you are trying to do:
01 - Running a separate server with DAM and importing into EPO?
02 - Running ePO with the fully integrated version of DAM?
If option 02, i found during my initial testing there was an issue with the Agent having duplicate GUIDS and some additional issue with the Agent communication. Support was working on a fix, provided me with a temporary solution. I would suggest checking the Rogue Systems - initially our DBMS never showed up, but was listed as a Rogue device. Once we found it and added to system tree it was ok.
I believe I understand the question now.
01 - Find the Sensors in your system tree (not the server host), and delete them.
02 - On the server host - restart the McAfee Framework service and the DBMS service.
03 - Perform wake-up or wait for ASCI to occur
04. Sensor should check back in and show the DBMS details.
I had this same issue and the above steps resolved it.
