Problem description
This document helps customers on how to resolve when they faced the issue while creating a backupset for Managed SQL Instance.
Cause
The absence of a subnet named “default” subnet to spawn the Druva's Quantum Bridge in Vnet where Managed instance is deployed.
Traceback
Failed to get subnet details: GET https://management.azure.com/subscriptions/27d73645-****-****-ba9c-4258*****/resourceGroups/Support/providers/Microsoft.Network/virtualNetworks/vnet-mitestpoc/subnets/default --------------------------------------------------------------------------------
RESPONSE 404: 404 Not Found ERROR CODE: NotFound --------------------------------------------------------------------------------
{ "error": { "code": "NotFound", "message": "Resource /subscriptions/27d73645-****-****-ba9c-4258*****/resourceGroups/Support/providers/Microsoft.Network/virtualNetworks/vnet-mitestpoc/subnets/default not found.", "details": [] } } -----------------------------------------------------------
Resolution
Login to the Azure subscription.
Go to Virtual Networks.
Select the Network that is assigned for Managed Instance.
Go to subnet Sections.
Create a “default” Subnet
Once the default subnet is created, you should be able to create a subnet successfully.
Note: The subnet attached to the managed instance is delegated and hence can't be used for Druva's Quantum Bridge.
