MPIO issue with Windows Server 2012 R2

Env:

Dell PowerEdge M950 using 2x Broadcom 57712-k Dual Port 10GbE NDC-k on WS 2012 R2

Equallogic PS6110 SSD

HIT 4.7.0

Issue:

Although the server has two NICs dedicated to iSCSI, only one path is used on all volumes, some volumes using one NIC, the others using the second NIC.

I also see repeated messages in the EventLog of the form:

Added device to \Device\MPIODisk13. DumpData contains the current number of paths.

then

Path 77020001 was removed from \Device\MPIODisk13 due to a PnP event. The dump data contains the current number of paths.

Any idea on what maybe wrong ?

Thanks
