```

{% endtab %}
{% endtabs %}

Environment

```javascript
2022-06-27 13:26:14.081 ERROR cinder.volume.utils [req-0d000c85-41af-4607-adec-67cfa4fa3f90 None transition1] Failed to copy image 13d05b01-XXXX-XXXX-XXXX-XXXXXXXXb40e to volume: 4de501bb-XXXX-XXXX-XXXX-XXXXXXXXd96a: os_brick.exception.NoFibreChannelVolumeDeviceFound: Unable to find a Fibre Channel volume device.
2022-06-27 13:26:15.032 ERROR cinder.volume.flows.manager.create_volume [req-0d000c85-41af-4607-adec-67cfa4fa3f90 None transition1] Volume 4de501bb-XXXX-XXXX-XXXX-XXXXXXXXd96a: create failed
```

{% endtab %}
{% endtabs %}

* The error indicates that the volume creation failed as cinder plugin was not able to find the associated `Fiber Channel Volume` at the backend SAN/NAS Storage .

## Resolution

* Try to check the Fiber Channel Connectivity with backend `SAN/NAS` storage through `SAN` or `Ethernet` switch with the storage team assistance.
* If no connectivity or hardware issues are found then try to manually attach a test FC volume from same `SAN/NAS` storage to the `Cinder` Host.
