At this time, SQL Server failover cluster instances on Azure virtual machines registered with the SQL IaaS Agent extension only support a limited number of features available through basic registration, and not those that require the agent, such as automated backup, patching, Microsoft Entra authentication and advanced portal management. See the table of benefits to learn more.
If your SQL Server VM has already been registered with the SQL IaaS Agent extension and you've enabled any features that require the agent, you need to delete the extension from the SQL Server VM by deleting the SQL virtual machine resource for the corresponding VMs, and then registering it with the SQL IaaS Agent extension again. When you're deleting the SQL virtual machine resource by using the Azure portal, clear the check box next to the correct virtual machine to avoid deleting the virtual machine.
