iSCSI Paths | Windows 2012 R2

Hi All,

I've been battling with a Windows Blade, that refuses to see all 4 storage paths, for a few days so thought I'd see if any of you can help out.

UCS 2.2(5b)

B200-M4

NetApp Clustered Mode, 2 nodes, 8.3

Lots of ESXi 6 Hosts, iSCSI boot, 4 paths

I've installed Windows Server 2012 R2 on a B200-M4 blade with a single path to the NetApp.

Installed UCS drivers for eNIC and Chipset.

Installed Windows Updates

Installed NetApp Host Utils (7.0)

Installed NetApp MPIO (4.1P1)

Put my boot policy back to having 4 paths, 2 targets in VLAN 201, and 2 targets in VLAN 203.

The server boots and runs fine but I only see 1 path through VLAN 201 and 1 path through VLAN 203. I can ping the target addresses, the VLANs are set to native and I'm pretty sure that my config is right as I have 10 ESXi 6 hosts all running nicely on 4 paths!

Any thoughts please?

Cheers,

Gerg
