These were previously not listed but are important to re-enforce to
avoid corruption of instances during an evacuation.

Evacuate Server (evacuate Action)
=================================
.. rest_method:: POST /servers/{server_id}/action
Evacuates a server from a failed host to a new host.
- Specify the ``evacuate`` action in the request body.
- In the request body, if ``onSharedStorage`` is set, then do not set ``adminPass``.
- The target host should not be the same as the instance host.
**Preconditions**
- The failed host must be fenced and no longer running the original server.
- The failed host must be reported as down or marked as forced down using
`Update Forced Down`_.
Starting from API version 2.68, the ``force`` parameter is no longer accepted
as this could not be meaningfully supported by servers with complex resource
allocations.
Normal response codes: 200
Error response codes: badRequest(400), unauthorized(401), forbidden(403),
itemNotFound(404), conflict(409)
