Unable to add second DAG Member in Echange 2013
I am have been having issues creating a DAG in Exchange 2013.
I have a scenario where I've got 2-DCs, 1-FileShare (non-exchange), Four Exchange Servers (1-CAS, 3-MBX).
I successfully create a DAG and try to add two servers to it. On each attempt, the CAS server adds without issues, but the MBX server fails to add with the following error:
"error
A server-side database availability group administrative operation failed. Error The operation failed. CreateCluster errors may result from incorrectly configured static addresses. Error: An error occurred while attempting a cluster operation. Error: Cluster API failed: "AddClusterNode() (MaxPercentage=100) failed with 0x5b4. Error: This operation returned because the timeout period expired". [Server: cas01.rshq.local]"
How do I get the second server to add so I can complete the DAG creation please? Looking forward to your help on this as I've been on this for over 2 weeks and can't seem to find a solution anywhere that works.

Yes i do have an static IP address for the DAG name and it is configured in DNS (forward and reverse lookup). as the first server has been added and the DAG CNO has become enabled, I can ping the DAG CNO (the name gets resoled to the IP accordingly).
I've got both a MAPI and a replication network on the Exchange server (prospective DAG member servers). All IPv4 addresses are manually configured, while IPv6 is set to DHCP (as am not using these yet).
I also noticed that the "witness directory" directory disappears immediately after the DAG gets created, is this normal?
Any further thoughts?

Hello Simon,
The CAS Server also host a Mailbox server role, however, all the others only host Mailbox roles. I think this would normally work - having a server with multiple roles installed joining the DAG, I have seen that before.
Any more ideas please?
Thank you.

Agree with Simon. For example if you have 2 CAS and 2 MBX. You change it 2 or 3 servers with all the roles installed.
This way you save hardware cost and sofware cost(Exchange license).
FYI CAS is a stateless server in Exchange2013 it is just an interface to clients.

Ok, I forgot to mention that the CAS also has MBX role installed.
I'll think of the multi-role servers option tonight and let you know what I decide and how I proceed.

Do you assign an static IP address for your DAG name? Make sure the host name appear in DNS server as well
