I purchased a reconditioned, (mistake don't yell), VNC 5300 from a reseller and have struggled for the past 60 days to get the device up and running.  After reading more threads, help documents and guides that I can count I am now concerned that I do not have all the pieces that I need.   Yes I have enlisted their support and after about 4 hours on the phone, we are still unable to make the iSCSI initiators work 100%

My Current Environment: 

3 Dell R720 computes in a Microsoft Failover Cluster with Cluster shared Storage.

1 EqualLogic P6100

1 EqualLogic P6010

Added equipment:  (thought I was replacing the EqualLogic Boxes)

VNX5300 - 90+ Raw TB Storage

I'm using iSCSI and have dual ports on SP-A & SP-B

My Question 1st:

Do I need PowerPath for Hyper-V in order to connect the VNX5300 using Multipath and work in a Microsoft Failover Cluster Environment?

Thanks, and depending on the answer I may follow up with additional questions.
