Inconsistency in CLI for hypervisor and baremetal node names

[Cédric Jeanneret]

Dear Stackers,

There is an inconsistency in tripleo CLI: we can run the following:
openstack baremetal node introspect controller-1

where "controller-1" the value of the "Name" column in openstack baremetal node list

But this command will eventually fail, because it will obsess with the following message:
[u"The action raised an exception [action_ex_id=7fdfb424-9732-4d61-b673-84d98557371d, action_cls='<class 'mistral.actions.action_factory.NovaAction'>', attributes='{u'client_method_name': u'hypervisors.find'}', params='{u'hypervisor_hostname': u'controller-1'}']\n NovaAction.hypervisors.find failed: No Hypervisor matching {u'hypervisor_hostname': u'controller-1'}. (HTTP 404)"]

After a small check with "openstack hypervisor list", we can indeed see the "Hypervisor Hostname" is set to an UUID, not a Hostname.

Now, the "Name" field of the `openstack baremetal node list' might be empty, so it makes sense Hypervisor Hostname uses UUID, but then we might want to forbid the use of "Name" for the `openstack baremetal node introspect' command.

What do you think? Code issue, or doc issue?

Cheers,

C.

It appears the problem is when using --provide

For example this works fine.
(undercloud) [stack@host01 ~]$ openstack baremetal node list
+--------------------------------------+-------+---------------+-------------+--------------------+-------------+
| UUID | Name | Instance UUID | Power State | Provisioning State | Maintenance |
+--------------------------------------+-------+---------------+-------------+--------------------+-------------+
| 4de51a48-abdc-4da7-85d1-4393b2bf9a90 | host2 | None | power on | manageable | False |
| ec6694c6-8c0c-437f-a7f6-82e7c2ab3793 | host3 | None | power on | manageable | False |
+--------------------------------------+-------+---------------+-------------+--------------------+-------------+

But when using --provides we get the error:

According to Dmitry the provide workflow cannot accept names.
