iSCSI Multipath with Hyper-V Core 2012 using Powershell
I am a real Powershell newbie and not real familiar with iSCSI either. I have just rolled out my first 2012 server using Hyper-V Core install on a Dell Poweredge server, putting the VM's on a Equallogic SAN. I followed the Step by Step guide here, http://blogs.technet.com/b/keithmayer/archive/2013/03/12/speaking-iscsi-with-windows-server-2012-and-hyper-v.aspx
but I don't think I have it right as far as MPIO is concerned.
On the server I have 4 nics, 2 on the lan subnet and 2 on the iSCSI SAN subnet, lets say the SAN Nics are x.x.40.1 and x.x.40.2. On the Equallogic there are 3 Nics, 1 on the lan for a management interface and 2 on the iSCSI subnet, say x.x.40.10 and x.x.40.20. The Equallogic also has a group member ip address on the iSCSI subnet, x.x.40.15
The 4 server nics and the 3 EQL nics are connected to a GB Switch.
So when I make my New-IscsiTargetPortal -TargetPortalAddress x.x.40.? I can make a connection on any of the 3 40.x addresses on the Equallogic. If I want MPIO to work should I use the group member ip? or do I need to make both of the physical Nics Portals?
If I make the Member IP the iSCSI target, then Enable-MSDSMAutomaticClaim
And there does not seem to be any command to show what nics are being claimed by MPIO DSM. Do I just have to monitor traffic on the 2 .40 nicks to see that both are being used?
Sorry for the naive newbie questions but the PS learning curve is steep and I have been pouring over the docs for days and this multipath business still remains obscure.

My experience with Hyper-V is that you don't need to use any PowerShell. Just use config to join the host to the domain and configure basic networking. Hyper-V Manager from a remote system for everything else.
