 # Requirements and considerations for application volume group for SAP HANA 
@@ -36,6 +36,9 @@ This article describes the requirements and considerations you need to be aware
 
     Application volume group for SAP HANA will create multiple IP addresses, up to six IP addresses for larger-sized estates. Ensure that the delegated subnet has sufficient free IP addresses. It’s recommended that you use a delegated subnet with a minimum of 59 IP addresses with a subnet size of /26. See [Considerations about delegating a subnet to Azure NetApp Files](azure-netapp-files-delegate-subnet.md#considerations).
 
+>[!IMPORTANT]
+>The use of application volume group for SAP HANA for applications other than SAP HANA is not supported. Reach out to your Azure NetApp Files specialist for guidance on using Azure NetApp Files multi-volume layouts with other database applications.

 ## Best practices about proximity placement groups
 
 To deploy SAP HANA volumes using the application volume group, you need to use your HANA database VMs as an anchor for a proximity placement group (PPG). It’s recommended that you create an availability set per database and use the **[SAP HANA VM pinning request form](https://aka.ms/HANAPINNING)** to pin the availability set to a dedicated compute cluster. After pinning, you need to add a PPG to the availability set  and then deploy all hosts of an SAP HANA database using that availability set. Doing so ensures that all virtual machines are at the same location. If the virtual machines are started, the PPG has its anchor.
