net app volume disappeared suddenly

Hi Hanuman Akella ,

I Understand the issue with your Azure NetApp volume. Check Logs and Monitoring This log provides insights into subscription-level events, including modifications to resources. You can view the activity log in the Azure portal or retrieve entries using PowerShell or CLI.

Azure NetApp Files Metrics Check metrics on allocated storage, actual storage usage, volume IOPS, and latency to understand the usage pattern and performance of your NetApp accounts.

Use this tool in the Azure portal to troubleshoot issues with Azure NetApp Files. Navigate to the tool and select the problem type you're experiencing.

Volume Reversion If you need to revert the volume to a previous state, you can use the snapshot revert functionality. This allows you to quickly revert a volume to the state it was in when a particular snapshot was taken.

• Go to the Snapshots menu of the volume.
• Right-click the snapshot you want to use for the revert operation.
• Select Revert volume.
• In the Revert Volume to Snapshot window, enter the name of the volume and select Revert.

Additional Information,

Ensure that the network configuration is correct and that DNS servers are available. Check if the volume and Active Directory Domain Services are deployed in the same region and virtual network, verify that the user has the necessary permissions to access and manage the volume.
