Hi @Ahammed Sakir ,
if you take a look in the Azure details you see the Managed By
information.
If the field is empty = disk isn't attached to a VM.
Otherwise you will see the name of the VM.
The third option is to take a look on the list view of Azure Disks. The column Owner
shows the related VM name.
