MSA 2040 and Active\Active Multipath with Round Robin load balancing policy

[skypojames]

Hi,

I'm unable to change the Load balance policy in my iSCSI connection.  My san has 2 controllers, each with 2 ports.  My server has 2 nics, each nic has a sperate IP subnet with a seperate dedicated switch for each controller\subnet.

I have 2 linear LUNs of 100 GB, one on each controller.  In the iSCSI initiator I have multiple paths to each lun, however in the MPIO configuration in the devices in iSCSI I cannot change the load balancing policy, I've done some screenshot.

Does anyone know why this might be happening?  I need to use round robin to increase the performance and utilise more thatn just 1 GB NIC.
