Hello all. I three Dell R710 VMWare hosts and a Dell MD3220 SAS SAN with dual controllers. The hosts each have a dual port SAS HBA and the ports are plugged into both array controllers. I'm having some disk performance issues and I'm trying to enable round robin to make use of both paths. When I change the path policy in VMWare from MRU to round robin, the paths still show one active, the other standby. Host has been rebooted. VMWare is version is 5.0.
