Configuring a c-Class enclosure

[Gambit5150]

I have an issue that is driving me crazy. I have a c-class enclosure with a 1:10Gb Ethernet switch in interface bay 5 and 6. Accessing the switch management, it shows that the ports are connected without any errors. I have a Windows server with a Mez card in slot 2. The switches are connected via 10GbE XFP to a 2-node LeftHand iSCSI storage device with 10GbE optional cards installed. Everything looks accurate, I have link lights and activity lights, and for some reason when I have the IP addresses of the LeftHand device and Windows server on the same subnet, it cannot ping and I cannot find the target device.

Please help!!!
