Hi, first of all my configuration:
1 HUB/CAS in the main site (192.168.100.1) that hosts the witness share
1 MAILBOX in the main site (192.168.100.2) member of the DAG
1 HUB/CAS in the DR site (192.168.60.1 / natted 192.168.113.1)
1 MAILBOX in the DR site (192.168.60.2 / natted 192.168.113.2) member of the DAG
Quorum configuration: Node and File Share Majority
From the main site i reach the DR site using the natted IPs and I've no problems during the replicas.
****
As I understood the DAG I shoud shutdown the witness server (HUB/CAS in the main site) without resulting in a failover state for the DAG. That is not happening. Every time I reboot the witness server the DAG DBs switch to the DR Mailbox server.
Considering the quorum configuration I was thinking that's the problem, but I'm not quite sure.
When I reboot che witness server my DAG Cluster try to switch over. Doesn't that give the DR DAG member the majority?
Is that right? Did I make a mistake during the configuration?
At the moment I changed the cluster configuration to use the main site DAG member as prefered and to failback automatically, but this is not a solution..
****
Second question. Due to my network configuration the Cluster IP resources fails to go online when the cluster switches in the DR site. As I wrote above I'm still thinking it shoudn't switch (or I need to change che majority configuration..), but for the sake of argoument I'm trying to understand how to configure a secondary DAG IP for the natted network in the DR site.
I tried, using the gui and powershell. DAG configuration is fine with 2 two DatabaseAvailabilityGroupIpAddresses IP's, but the cluster configuration (under Cluster Core Resources) shows only one ip address (the main site one).
Thanks
