I'd like to know if i can be able to enable lag on the controller but termite it on 2 different switches? i.e. i have 2 ports on the controller, i connect 1 port on switch1 int g1/5 and connect port on switch3 port 1/10?
How can i do this? as i need to configure etherchannel right?
No, the ports have to be connected to the same switch. Reason being you have to setup a port-channel on the switch for those ports. The only exception to spanning multiple switches is if you have 3750's in a stacked configuration.
