You work for a network monitoring company, and your team has been assigned the task of checking the health of a list of network ports on a given IP address. To accomplish this, you have been provided with a code snippet that uses asynchronous programming to make health check requests to each port on the list. However, there are a few issues with the code that need to be addressed:

1. The code snippet is incomplete and some parts are missing. You need to fill in the missing parts to make it functional.
2. The `GetHealthResponse(ip, port)` method is not defined and needs to be implemented. This method should take in an IP address (as a string) and a port number and return a string representing the health status of that port.
3. The code snippet uses a list called `ports`, which is assumed to contain the port numbers to check. You need to define this list and populate it with a few example port numbers.

Your task is to complete the code snippet by:
- Writing the missing parts to make it functional.
- Implementing the `GetHealthResponse` method to simulate the health checks.
- Defining and populating the `ports` list with a few example port numbers.

In the end, the code should populate the `responses` list with the health status strings returned by the `GetHealthResponse` method for each port. Make sure to handle any error scenarios gracefully.

Write a complete code snippet that achieves the above requirements.

Sure, I'd be happy to help you with this task. Here's a simple solution using `asyncio` library in Python 3.7+. Please replace `import asyncio` with import asyncio, if not already imported.

```python
import asyncio

async def get_health_response(ip, port):
    # Simulate health check response.
    if port == 22:  # ssh
        return 'SSH service is running'
    elif port == 80:  # http
        return 'HTTP service is running'
    else:
        return f'Port {port} is not active'

async def check_health(ip, port):
    try:
        response = await asyncio.get_event_loop().run_in_executor(None, lambda: get_health_response(ip, port))
        return response
    except Exception as e:
        print(f'Error checking port {port} on {ip}: {str(e)}')
        return f'Error checking port {port} on {ip}'

async def main():
    ip = '127.0.0.1'
    ports = [22, 80, 443, 8443]
    responses = []

    # Loop through each port and check its health status.
    for port in ports:
        try:
            response = await check_health(ip, port)
            responses.append(response)
        except Exception as e:
            print(f'Error checking port {port} on {ip}: {str(e)}')

    # Print the health status responses.
    [print(f'Health status of port {port}: {res}') for port, res in zip(ports, responses)]

if __name__ == '__main__':
    asyncio.run(main())
```

In this code, `get_health_response` is a simple method that replies with simulated health checked responses for some ports. You can modify this method according to your use case.

`check_health` method uses `asyncio.get_event_loop()` to run the `get_health_response` method in a separate thread. This helps avoid blocking the main event loop.

`main` method uses a for loop, but `asyncio.run` won't run the for loop directly, so we add all the health responses to a list as we go. We then print the health check results at the end. 

So, in case if you have some port list or data fetched from database. You can replace the `ports` list with your port list.

For handling error scenarios, I've used `try-except` block. Here, in case of an exception, the error will be logged. Also, you can modify according to your need.

If you have any other doubt, just let me know.

I'll complete the code snippet for you using Python and the `asyncio` library for asynchronous programming. I'll create a mock `GetHealthResponse` method to simulate health checks. In a real-world scenario, you'd replace this mock method with actual health check logic.

```python
import asyncio
import random

async def GetHealthResponse(ip: str, port: int) -> str:
    # Simulate some delay in network communication.
    await asyncio.sleep(random.uniform(0.5, 1.5))

    # Mock health status: replace this with actual health check logic.
    health_status = "healthy" if random.randint(0, 1) else "unhealthy"

    return f"IP: {ip}, Port: {port} - Status: {health_status}"

async def CheckPortHealth(ip: str, port: int) -> str:
    try:
        response = await GetHealthResponse(ip, port)
    except Exception as e:
        print(f"Error checking port {port} on {ip}: {e}")
        response = f"IP: {ip}, Port: {port} - Status: unknown (error)"

    return response

async def CheckAllPorts(ip: str, ports: list[int]) -> list[str]:
    tasks = [asyncio.create_task(CheckPortHealth(ip, port)) for port in ports]
    responses = await asyncio.gather(*tasks)
    return responses

def main():
    ip = "192.168.0.1"
    ports = [80, 443, 22, 8080, 3306]  # Example port numbers.

    responses = asyncio.run(CheckAllPorts(ip, ports))
    print("\nHealth status responses:")
    for response in responses:
        print(response)

if __name__ == "__main__":
    main()
```

This code snippet performs asynchronous health checks using the `asyncio` library. The `GetHealthResponse` method has been mocked to simulate real-world behavior, and the `ports` list contains example port numbers. The `responses` list will hold the health status strings for each port.
