I run create and assign volume to server via heat tempale

"server": {
    "type": "OS::Nova::Server", 
    "properties": {
       "image": {"get_param": "image_id"}, 
       "flavor": {"get_param": "instance_type"}, 
       "name": {"get_param": "instance_name"}
 "volume": {
   "type": "OS::Cinder::Volume",
   "properties": {
      "name": {"get_param": "volume_name"},
      "source_volid":{"get_param": "volume_id"}
 "volume_assign": {
    "depends_on": "volume",
    "type": "OS::Cinder::VolumeAttachment",
    "properties": {
       "instance_uuid": {"get_resource": "server"},
       "volume_id": {"get_resource": "volume"}

When I login to server I don't see the attached volume. When I do the restart to this instance I can access to it.

My question is if I have any option to restart server( instance ) via template?

If your devices are connected using PCI, you should issue a rescan of the PCI bus.

echo 1 > $(ls /sys/class/pci_bus/*/rescan)

You can use a cloud-init script to run this command automatically with the instance boot.

There is not, unless you do it in a user data script or a software deployment. e.g. check if the volume is attached, and if not reboot - although it seems likely that there is a less drastic way to force the volume to be mounted.
