Good morning,
I'm trying to uninstall Exchange 2013 from one of my servers and the readiness check fails with an error about the DAG/Cluster.
Error:
This computer is a member of a database availability group (DAG). It must be removed from the DAG before you can uninstall Exchange.
For more information, visit: http://technet.microsoft.com/library(EXCHG.150)/ms.exch.setupreadiness.CannotUninstallClusterNode.aspx
I had previously removed the server in question (Exchange04) from the DAG, and running the GUI (Exchange Admin Center, Failover Cluster MMC) and PS tools seems to confirm it's no longer a DAG member:
[PS] C:\Windows\system32>Get-DatabaseAvailabilityGroup
Name Member Servers
Operational Servers
---- --------------
-------------------
Exchange-DAG {EXCHANGE05}
However, it's still being linked to the DAG somewhere and I'd like to be able to sort this out and move on. I'd appreciate any ideas.
Thanks,
Greg
