On IOS device you just need to add one more tacacs server. First on the list would be primary and if there is no response from primary tacacs , it will fwd request to next listed tacacs server.

This is how you add tacacs on IOS device

Router(config)#tacacs-server host x.x.x.x key cisco

Router(config)#tacacs-server host y.y.y.y key cisco
