@ -11,6 +11,12 @@ Evacuates a server from a failed host to a new host.
- 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.
