# Setting Cinder Storage Credentials On Premise

This article explains how to set storage appliance credentials to your block storage node.

### Prerequisites

You must have a Cinder block storage node authorized and connected.

### Step 1

Log in to the Linux host which you have assigned the Cinder block storage role.

### Step 2

Change directory to: `/opt/pf9/etc/pf9-cindervolume-base/conf.d/` .

{% tabs %}
{% tab title="Bash" %}

```bash
cd /opt/pf9/etc/pf9-cindervolume-base/conf.d/
```

{% endtab %}
{% endtabs %}

### Step 3

Create a file named `cinder_override.conf` (note the underscore):

{% tabs %}
{% tab title="Bash" %}

```bash
touch /opt/pf9/etc/pf9-cindervolume-base/conf.d/cinder_override.conf
```

{% endtab %}
{% endtabs %}

Add a `[DEFAULT]` section and list all the backends you wish to enable using the `enabled_backends` option in this section. Add the appropriate parameters for each backend as needed by the respective driver in a backend-specific section. Please refer to your storage vendor's manual for more information on which configuration options are available.

{% hint style="info" %}
**Note**

Cinder was upgraded to the Stein release in 4.2 release of Platform9. The config options iscsi\_ip\_address, iscsi\_port, iscsi\_target\_prefix and iscsi\_protocol were deprecated in the Queens release and have now been removed. Deployments should now use the more general target\_ip\_address, target\_port, target\_helper, target\_prefix and target\_protocol options. For example, if LVM configuration has option iscsi\_ip\_address, it needs to be changed to target\_ip\_address. For more information, please check <https://docs.openstack.org/releasenotes/cinder/stein.html#relnotes-14-0-0-stable-stein-upgrade-notes>.
{% endhint %}

Example (for QNAP):

{% tabs %}
{% tab title="cinder\_override.conf" %}

```yaml
[DEFAULT]
enabled_backends = qnap
[qnap]
san_login = admin
san_password = changeme
```

{% endtab %}
{% endtabs %}

### Step 4

Restart the `pf9-cindervolume` service. For example, on Enterprise Linux operating systems e.g. CentOS:

{% tabs %}
{% tab title="Bash" %}

```bash
service pf9-cindervolume-base restart
```

{% endtab %}
{% endtabs %}
