DELL POWER VAULT MD3820I Series Configuration

Hello,

i have, Dell power Vault MD3820I san Storage with two controller card, each controller have two iscsi ports. and i connected both of them with both two the switches. 

like:- controller 0/Port0/Switch1/Port2

         Controller 0/Port1/Switch2/Port2

          Controller 1/Port0/switch1/Port3

          Controller 1/port1/switch2/port3

And,

I have Dell Power Edge R720 Server with dual 10G interface, i have installed Red Hat 7.2. 

and done the Bonding between two 10G interface, Active backup mode.  

10G Port/Switch1/Port4

10G Port/Switch2/Port4

Now, the issue i am facing is:-

whenever i try to create Session from dell utility software to manage SAN storage its says time out and when i remove the bonding from 10G interface and use only single interface it works fine.

what should i do?
