Uninstalling Exchange clustered mailbox servers
Posted on 2009-07-13
Hi all - I need to completely uninstall Exchange mailbox cluster and reinstall to correct issues with the first installation. We are moving from Exch 03 to 07; there will be a mixed environment until we bring the Exch 07 org fully online. So I have 3 Exch 03 servers, two CAS/Hub and 2 mailbox servers to be set up in a CCR.
When I did the mailbox server installs the first time, I wasn't thinking and rebooted the active member before installing Exch on the passive member. The cluster failed over to the passive member, but since that didn't have Exch on it yet, I could not install the passive role on that server and had to start all over. I finally got Exchange uninstalled on both servers, but the cluster mb server is still showing in Exch 03, even though it no longer exists. I went back to the information store folders located on both the new servers and deleted those files, which now appears to have been a mistake.
When I try to reinstall on the active member, the installation errors out and says it could not find required info on that server.
How do I get back to a point where I can uninstall and then reinstall?
