Attaching an empty disk is a simple way to add a data disk, because Azure creates the .vhd file for you and stores it in the storage account.
-
Click Virtual Machines (classic), and then select the appropriate VM.
-
In the Settings menu, click Disks.
-
On the command bar, click Attach new.
The Attach new disk dialog box appears.
Fill in the following information:
- In File Name, accept the default name or type another one for the .vhd file. The data disk uses an automatically generated name, even if you type another name for the .vhd file.
- Select the Type of the data disk. All virtual machines support standard disks. Many virtual machines also support premium disks.
- Select the Size (GB) of the data disk.
- For Host caching, choose none or Read Only.
- Click OK to finish.
-
After the data disk is created and attached, it's listed in the disks section of the VM.
Note
After you add a data disk, you need to log on to the VM and initialize the disk so that it can be used.
Attaching an existing disk requires that you have a .vhd available in a storage account. Use the Add-AzureVhd cmdlet to upload the .vhd file to the storage account. After you've created and uploaded the .vhd file, you can attach it to a VM.
-
Click Virtual Machines (classic), and then select the appropriate virtual machine.
-
In the Settings menu, click Disks.
-
On the command bar, click Attach existing.
-
Click Location. The available storage accounts display. Next, select an appropriate storage account from those listed.
-
A Storage account holds one or more containers that contain disk drives (vhds). Select the appropriate container from those listed.
-
The vhds panel lists the disk drives held in the container. Click one of the disks, and then click Select.
-
The Attach existing disk panel displays again, with the location containing the storage account, container, and selected hard disk (vhd) to add to the virtual machine.
Set Host caching to none or Read only, then click OK.
