After setting up an SFW environment with Microsoft clustering on the primary site, complete the same tasks on the secondary site before the SQL installation.
However, note the following guidelines and exceptions:
If the DR site is on a different network segment, ensure that you allocate two IP addresses for the virtual server, one for the primary site and one for the DR site.
During the creation of disk groups and volumes for the secondary site, make sure the following is exactly the same as the cluster on the primary site:
Specify the same name for the SQL Server resource group as the name on the primary site.
Before starting the SQL installation make sure you take the SQL Server Network Name resource offline on the primary site. This will also offline the dependent SQL resources. In addition, if the secondary is in the same subnet, take the IP Address resource offline on the primary site.
During installation, specify the same name for the SQL virtual server as the name on the primary site.
