Not handling more than two MPIO connections

Is there a command to enable the HIT Kit to allow more than two MPIO connections?

I have a Windows Server with four dedicated iSCSI NICs, and the MPIO software from the HIT kit is not able to sustain more than two MPIO connections.

I can introduce a third and fourth session, but the MPIO software drops these connections after less than a minute.

Here's my configuration:

- Dell EqualLogic PS6500X (one member)
- Windows Server 2012 R2 iSCSI initiator
- HIT Kit version 4.7.

MPIO Configuration:

• MaxSessionsPerVolumeSlice : 4
• MaxSessionPerEntireVolume : 6
• DefaultLoadBalancing      : 4
• DefaultLoadBalancingText  : Least Queue Depth
• MinAdaptorSpeed           : 1000
• UseMPIOForSnapshots       : True
• UseIPv6                   : False
