# Using "Nova Service-Force-Down

## Problem

While trying to run the\*\*`nova`\*\* command for **`service-force-down`** we get the following error.

{% tabs %}
{% tab title="None" %}

```none
# nova service-force-down [host uuid] nova-compute    error: unrecognised arguments: nova-compute
```

{% endtab %}
{% endtabs %}

Looking at the usage of the command it tells us to use "ID" as the argument.

Usage: **`nova service-force-down [--unset] [id]`** does not specify which id to be used.

## Environment

* Platform9 Managed OpenStack - v4.0 and Higher
* Nova CLI (python-novaclient)

## Procedure

1. The ID to be used in the command is of the compute service for a host.

{% tabs %}
{% tab title="None" %}

```none
# nova service-force-down [--unset] [id]
```

{% endtab %}
{% endtabs %}

2. This IDcan be obtained using the following command.

{% tabs %}
{% tab title="None" %}

```none
# nova service-list
```

{% endtab %}
{% endtabs %}

Thefirst column in the outputof the above command will get you the id of the binary and this id should be used with the command **`nova service-force-down [--unset] [id]`** to force up or down the nova-compute service.
