During a replication the job throws an error of 'No virtual appliance is configured for this host.'
There are two methods that tend to resolve such an error message.
1) If there are available hardware resources provide a host based VA for the hosts that are replicating so that they can have their own VA in order to perform the replication jobs.
2) Delete the cluster based VA that Ranger is unable to locate and reploy another VA. This task can be performed through Ranger itself through Tools > Options > Virtual Appliance > Configuration. Here you can select your VA and delete it (if so make sure to select the checkbox 'Delete from host' upon confirmation). There is also the option on the same window to 'Deploy a Virutal Appliance.'
