I have a migration from 2003 to 2010 and I'm in the process of creating the DAG group and adding 2 Exchange 2010 servers to it.
So I have 2 servers with 2 NICs on each server and 3 TB on each server too with all the roles installed on each of them.
I created 4 databases on each server and created one DAG for replication of the databases between both server but there seems to be a problem.
I have 2 NICs on each server, one is in the LAN for MAPI and the second is on a different Subnet and different physically connected network too for replication.
when I try to setup the DAG it asks for the witness server and folder which I have already setup and added the required Exchange security group permission to the local administrator "Exchange Trusted Subsystem".
The DAG group gets created but with only one Mailbox server or one of the two servers that I have installed.
When I try to add the second server I get this error:
error: a server-side database availability group administrative operation failed, error: The operation failed. createcluster errors may result from incorrectly configured static addresses.
I am also attaching a snapshot of the error. I couldn't get around this problem and hope that someone could know what's the solution?
Just would like to mention 2 things more, I have configured manually the IPs of the replication NICs as following
First SERVER/REPlication NIC
Second Server/ Replication NIC
Second thing, the customer doesn't have a DHCP server in the Servers subnet which had me to manually configure a Static IPs for the DAG group.
