Hi, I have 2 physical mailbox servers and an EVA 4400 storage. I presented many LUNs o hold exchange databases and they are working fine. After installing DPM 2012 agent, I tried to present more LUNs but every time the server hangs and I have to reset it. Also, I had to uninstall DPM agent in order to be able to present new LUNs successfuly. I dont know what is the relation between DPM agent and presenting more LUNs to a server. 2 mailbox and DPM servers are Windows 2008 R2DPM 2012 that has been upgraded from 2010
