If I continue this recovery, will there be any impact on the production Orion host and database?
Will the eval copy of Orion begin polling the network?
Kinda. Since the database "tags" each node with the name of the polling engine responsibile, the DR copy won't do much of anything since that polling engine isn't assigned any nodes to poll. But it COULD start polling nodes if you re-assigned them. (See below for more info)
I probably should shutdown the production hosts to test the DR, but just wondering what happens if I don't.
IMHO you shouldn't need to. With that said
More about your DR test
The problem with this test is that it doesn't really test how you would actually do things in the case of a disaster. The reason I gave above for why the DR poller won't actually do anything is the same reason this isn't a valid DR test. In order to make a complete test of DR, you would need to:
A) re-assign all nodes to start using the DR polling engine (it might be as simple as a SQL Update query to change the polling engine ID. BUT I DON"T KNOW, SO YMMV.
B) remove the references to the production poller from the installation
There are other ways to achieve a DR test that may be more accurate in the long run. A lot depends on what is required to be running in DR for you to pass audit.
Thanks for the helpful answer. Yeah, I'm just doing something informal that I initiated myself. I'm not testing automatic failover. Basically, I want to see how to load a backup of the production DB into a new SW Orion host. So far so good. But now I will see how I will point the DR setup to the new polling engine.
