I have ran into interesting problem trying to create 2 node Windows Server 2012 R2 Failover Cluster for SQL Server.
I have 2 Proliant DL360 servers running Windows Server 2012 R2 Standard version. I also have HP MSA2040 Dual SAS Controller SAN. Both servers have dual HBAs that connect to both controllers. Everything looks healthy on both servers and MSA. I created VDisks and Volumes and mapped them.

When I go to Disk Management of the servers, I see duplicate drives listed because HBA's connect to both MSA controllers.
Second set of drives is offline and the status message says because they are redundant. This shows on both servers.

My Failover Cluster validation test comes back failed when it goes to test storage with following reason:

Two disks have been found on node Donnie1.hq.ift.org that cannot be distinguished from one another. The disks involved have disk signature ad139f75, SCSI page 83h VPD descriptor 600C0FF0001E3C9B58AE7D5401000000, SCSI page 80h VPD Serial Number 00c0ff1e3c9b000058ae7d5401000000. Please verify the storage configuration. You must either mask (unpresent, detach) one of these LUNs at this node, or, run validation and specify a disk list that includes only one of these disks, for example by using the Test-Cluster cmdlet in Windows PowerShell.

If I disconnect second input on each HBA and only have one cable go to each controller, validation test passes 100%.
But then I have no redundancy.

I reached out to HP and they found everything in order.
Any advise is appreciated.
Thanks,
Lev

Add the MPIO feature in server manager for each node so windows knows about and can proper manage redundant routes.
