Description Roman Hodain 2015-01-07 09:37:34 UTC 
Description of problem:
The resilience policy is explained in the Administration guide inthe following way:

================================================================================
4.2.2.3. Resilience Policy Settings Explained
The resilience policy sets the virtual machine migration policy in the event of
host failure. Virtual machines running on a host that unexpectedly shuts down or
is put into maintenance mode are migrated to other hosts in the cluster; this
migration is dependent upon your cluster policy.
================================================================================

Here are the problematic topics:
1) It does not affect the behaviour when the host is put into maintenance mode. We always try to migrate all VMs if possible

2) In case of the host failure we always restart the HA VMs on another host if possible. Does not matter what is set in the cluster policy. The non HA VMs are not.

This basically affect only the non-operational state of the host.

Reviewed in cs22765.

The two types of host failure have been clearly outlined and VM migration details have been clarified. One GUI element updated in QA pass.

Updated in Admin Guide production spec cs23027:

Virtual Machine High Availability Settings Explained [10397-749097]
Resilience Policy Settings Explained [7666-749089]

Updated Revision History [34613-749099]
