Resilience cluster policy is not explained in a confusing way
Last modified: 2015-07-23 08:58:58 EDT
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.
