Hi, @Saimon Najashi Welcome to the Microsoft Q&A forum, and thanks for reaching out.
Azure Arc-enabled servers let you manage Windows and Linux physical servers and virtual machines hosted outside of Azure, on your corporate network, or another cloud provider. With SQL Server extension on top of Azure -Arc server, let you manage SQL Server instances from Azure. In order for SQL Server arc enabled, the server must be arc enabled at first.
- If the server is not hosting SQL Server, you will just arc enable your server. Plan and deploy Azure Arc-enabled servers - Azure Arc | Microsoft Learn
- If the server also hosting SQL Server, there are multiple ways you can arc enable your SQL Server.
a. If the Server is already Arc enabled by using step#1, then you can simply register the SQL Server extension. Go to Server -Arc resource \Settings \Extensions \Add “SQL Server Extension -Azure Arc”. This will install SQL Server Arc extension and start managing SQL Server from Azure.
b. If you need to register several SQL Servers on Arc connected servers, you can also register SQL Server at scale using Azure Policy Connect SQL Servers on Azure Arc-enabled servers at scale | Microsoft Learn - If the server hosting SQL Server, but not arc enabled yet, then you can use the method directly:Connect your SQL Server to Azure Arc | Microsoft Learn This method first enable Arc -server under the hood and register SQL Server.
Please let me know if the information is helpful.
