VNX 5300 and Microsoft HyperV Failover Cluster
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.

Hello, no you do not need PowerPath to connect a Windows Failover cluster to a VNX5300.
You do not mention the OS version.
I'm assuming you are using iSCSI on the parent servers. iSCSI is supported as long as you use the MS iSCSI initiator and not the software initiator that may come with the iSCSI HBAs.
I have never tried those HBAs either so can't say yay or neh on that.
I do recommend you check the docu5134_Host-Connectivity-Guide-for-Windows and how to manually configure the iSCSI initiator.
Regards, Michel.

Thanks for the response as it confirms much trial and error... Let me give a bit more details.
Yes, I am using the MS iSCSI Initiators for the VNX ONLY.
3 Node MS Cluster running Windows Server 2012 Data Center Edition
2 Brocade 1020 HBA's in each of the 3 physical cluster.
Ports 0/0 & 1/0 Teamed for SAN
Ports 0/1 & 1/1 MPIO for SAN side using Dell EqualLogic supplied iSCSI initiators.
My overall goal here is to:
- add the VNX5300 into the cluster
- move all the VM's and storage to the VNX5300
- Remove the EqualLogic Devices and turn the off forever.

So yes that should work. Be aware of these articles which may cause you problems when you hit performance limits.
