I believe I know the answer to this, but want to verify.
We are currently setup in a 3-node DAG with 2 of the nodes in our production site and the 3rd node in our DR site.  We want to make sure that if and when failover occurs, the cluster resource will remain within our production site.  To me, this is the simple notion of unchecking the box for Possible Owners in Failover Cluster Manager.  Is there some gotchas with this?  I realize that a real disaster involves manual actions at the DR site to bring it online for Exchange.

Thanks.

Dennis,

Don't make changes here this could break your whole DAG configuration.
Simply add a Witness Server in the production site. This will ensure that the cluster resource will remain in the production site.

Indeed when the DR needs to be brought up back online some manual actions are required. Don't forget to enable DAC mode in this case.

Regards,
Johan

This isn't what happens, we do have a witness server in the production site, but we still experience the cluster resource failing over to the DR site.  I know about enabling DAC mode.

In which scenario do you see this behaviour?

This can happen whenever the owner of the cluster in the production site is rebooted or has an issue that initiates a failover.

Ok that indeed could be things which cause this issue. Very interesting I am going to do some investigation on this and will let you know the results.

Johan
