Before you begin installing SQL Server, note the following prerequisites for installing in the SFW environment:
Make sure that you have created the SFW disk groups and volumes for SQL Server.
Make sure that you have created the SQL Server resource group and added the resource for the SQL Server disk group.
Make sure that the SFW cluster disk group for SQL Server is imported to the first node and the volumes are mounted.
Make sure that each node has a local drive letter in common with all the other nodes in the cluster to enable installation of the binaries in exactly the same path on each cluster node.
If you are installing on a secondary site for a disaster recovery configuration, make sure that you take the SQL Network Name resource offline on the primary site before you begin installation on the secondary site. This will also offline the dependent resources. If the sites are on the same subnet and therefore use the same SQL IP address, ensure that the IP Address resource is offline on the primary site before beginning installation on the secondary site.
Ensure that the [NT AUTHORITY\SYSTEM] account is granted the sysadmin server role (from SQL Management Studio Console) on each node.
