Vinod,  
You can rely on the serial param.

```auto
- name: test play
  hosts: webservers
  serial: 1

```

```auto
And track the status in a variable or using local file to decide whether to execute task on the 2nd host or not

```

```auto

```

```auto

Thanks for your reply. But here we have 1000 servers where I need to run like my command should try to execute in domain A , if domain is not reachable the it should automatically trigger to domain B
