Open Stack

      How does openstack finds whether an ironic node is on or off? In
the following example,

[raub at irony ~]$ openstack baremetal node list
+--------------------------------------+------+---------------+-------------+--------------------+-------------+
| UUID                                 | Name | Instance UUID | Power
State | Provisioning State | Maintenance |
+--------------------------------------+------+---------------+-------------+--------------------+-------------+
| 6ae69caa-970e-4749-9545-7f3854299bef | nod1 | None          | power
off   | available          | False       |
| 86f28a6f-22c1-4352-a841-cfb370ed62ca | nod2 | None          | power
off   | available          | False       |
| bf8317d2-6ef1-4aa3-83b3-25bafa993711 | nod3 | None          | power
off   | available          | False       |
+--------------------------------------+------+---------------+-------------+--------------------+-------------+
[raub at irony ~]$

I know the 3 nodes are alive and running, but openstack does not seem
to agree with me.
