How to make same ssid's not to interfere each other

Question

My machine is configured with 2 Access points with same SSID's

1. Aruba Ap
2. Hostapd (wlan0_0 )

Whenever my machine connects to Aruba client is supposed to connect Aruba AP if not it should connect to softAp

For that I did port down of hostapd say wlan0_0 down whenever we connects to Aruba. But the problem is after I reset the connection to Aruba, client is not connecting to aruba and it has been observed that Even the hostapd port was down it is sending probe response and at the time of authentication it is faling..As the SSId of the aruba and hostpad are same it client is not connecting to both that means hostapd is interfering with the Aruba. So can you please help me how to use same ssid with no interference ......
