Creating databrick fails with exception VirtualNetworkIdChangeNotAllowed - Inbound/Outbound Network Security Group

[rodneytamblyn]

[Enter feedback here] On attempting to install the Azure Databrick I got the following error

Updating required Virtual Network from /subscriptions/xxxxxxxxxxxxx/resourceGroups/ob-services/providers/Microsoft.Network/virtualNetworks/xxxxxxxxxx-vnet to /subscriptions/2xxxxxxxxxxxx/xxxxxxxxxx/providers/Microsoft.Network/virtualNetworks/xxxxxxxx is currently not allowed (Code: VirtualNetworkIdChangeNotAllowed)."

The issue arises when the Inbound/Outbound Network Security Group (NSG) rules are not whitelisted prior to creating a workspace. This prevented creating the workspace.

To address this, it is necessary to refer to the following documents and manually implement the required security rules:

URL: https://learn.microsoft.com/en-us/azure/databricks/administration-guide/cloud-configurations/azure/vnet-inject

URL: https://learn.microsoft.com/en-us/azure/databricks/administration-guide/cloud-configurations/azure/vnet-inject#network-security-group-rules-for-workspaces-created-after-january-13-2020

I would recommend that these instructions be tested and if necessary:

• the deployment process should be updated to ensure the required rules are set
• at a minimum the documentation is updated to assist users to resolve this issue without having to go through support.

Thank you

Rodney
