In this Ask the Admin, I’ll show you how to attach a data disk to a virtual machine (VM) in the new Azure Management Portal.

Adding an additional disk to an Azure VM was easy and intuitive in the classic Azure management portal, but while the new portal has some benefits, sometimes the endless array of options and sliding panels makes it harder to find basic configuration options.
There are lots of reasons why you might want to attach additional disks to VMs in Azure, but one common situation is the requirement to host Active Directory database files on a volume that doesn’t use write caching. By default, Azure deploys OS volumes with write caching enabled, and this can cause issues, such as data loss, with some applications.
If you’ve never deployed a VM in Azure before, see Deploy VMs Using Azure Resource Manager on the Petri IT Knowledgebase. Azure Resource Manager (ARM) is the default deployment model for provisioning VMs, and other resources, in Azure using the new management portal. For more information on Azure resource groups, see What are Microsoft Azure Resource Groups? on Petri.
Before starting, you need to already have a virtual machine deployed in Azure. It doesn’t necessarily need to be running.

Creating and attaching the disk might take a few minutes, and once the task is complete, you should see a notification appear in the top right of the management portal. The new disk will also appear in the Disks pane if you haven’t already closed it.
