Hardware Raid Configuration

[Nilesh]

### Describe the bug

* I am looking out for a way to configure hardware raid, as mentioned in the example.
~~~
  raid:
    rootVolume:
      name: true
      sizeGB: "MAX"
      raidLevel: "1"
      physicalDisks:
        - "disk1"
        - "disk2"

~~~

#### Expectation

* We should be able to configure hardware raid using bifrost, as the underline it is using the ironic api only.

* also Ironic-api and inspector is running behind it, so I guess we should be able to perform raid config.

~~~

~~~

* Same for bios as well,

~~~

* Looking out for a confirmation and a sample json file.

Thanks,
cNilesh.

An examples provided on the same pages:

What the issue?

[Nilesh (cnilesh)]

@mmalchuk - no issues so far, checking if the said example is usable in bifrost or not? Ironic example is still usable on bifrost right?

[Maksim Malchuk (mmalchuk)]

Right. It should. Don't remember any deprecations.

Bifrost is automation to setup a small Ironic standalone cluster and (optionally) deploy servers using it.

You're correct that, AFAICT, there's no support in node inventory files for you to add this directly. However, you've got three options to move forward:

- You can run that command, as documented, against nodes configured with bifrost -- it should work as long as that guide is followed. A bifrost installed ironic is still ironic.
- Enhance bifrost by using it in ansible playbook mode, so that you can more easily modify the playbook to add the step to setup raid config: https://docs.openstack.org/bifrost/latest/user/howto.html#use-playbooks-instead-of-bifrost-cli
- If we want to support this natively in bifrost inventory, this would have to be written up as an RFE (this bug would do, we'd just need to do some basic design). This would likely be the longest path, unless you were willing to implement it.
