Hi,
We have our primary Data Centre where we have 2 MS SQL 2012 Enterprise Servers and 2 SharePoint 2013 Enterprise servers. We have SQL High Availability group implemented on our primary Site (Site A)
Site A has subnet of 192.168.0.0.
We recently added a new DR Site (Site B). Site B we have MS SQL 2012 Enterprise Servers. Site B have a subnet of 172.1.1.0
Both sites are connected via a VPN Tunnel. MS SQL 2012 Enterprise Server on Site B has been added in have SQL High Availability group of Site A.
SQL High Availability group have 2 IPs 192.168.0.32 and 172.1.1.32. SQL Listener have 2 IPs 192.168.0.33 and 172.1.1.33
We want to make sure that if Site A completely down then Site B work as an active Site. But when Site A down we are unable to ping High Availability group and Site B is unable to work as active site. SQL and SharePoint services are completely down.
Site A has AD(Primary Domain Controller) and Site B has ADC(Additional Domain Controller).
. Site A has witness server.
We are using Server 2012 Data Centre
Please suggest.
