MD3000i and Multipathing in ESX 3.5

Hello.

We're in trouble setting up multipathing with MD3000i.

We've a dual controller MD3000i, with one Virtual DIsc configured. MD3000i is connected to 2 ESX 3.5 Hosts.

We want to assign a different controller/path to a each ESX Host.

MD3000i is MRU (Most Recent Used) in Path Selection policy in ESX by default, so We're unable to specify the path for each ESX Host. If we change to Fixed (besides we can see error messages in MD3000i log: array not optimal, Volume not on preferred path due to AVT/RDAC failover), after rebooting the ESX Host the policy changes back to MRU again.

When it use MRU, sometimes, it can happen that each host uses a different path, but this is not controlable.

Is it possible to assign a different path to each ESX Host?

Thanks!
