getVolumesAttached to server

Hello,

is there any method to get the attached volumes into server?

for example:

```
compute = $openstack->computeV2();
$server = $compute->getServer(['id' => 'server-id']);

// Get attached volumes
$volumes = $server->getVolumesAttached();

```

or how can I see if there is any volumes attached to the server?

Thanks
