Setting preferred HT on Exchange 2010 DAG
Posted on 2011-05-03
We have the following as a test scenario :-
1 x CAS + HUB
1 x HUB + MB + DAG
1 x HUB + MB + DAG + CAS
We've set the DAG up and it fails over nicely for the mailbox DB's. For the HUB service, we have a POPBeamer client which sends mail to the DAG IP.
We are able to telnet into the DAG IP for both POP and SMTP and it resolves.
Basically, it works well until we push a fail-over to the second MB server.
The question is this :-
After the DAG is restored, the preferred HUB or CAS is still the second server, and not the first. This has traffic implications for our site, and is not ideal . . .
Is it possible to force which CAS or HUB server is preferred, if you have multiple ?
Thanks in advance
