On the Edit template blade, in the section displaying the content of the template, insert the following code starting with line 20 (directly underneath the "resources": [ line):

Note: If you are using a tool that pastes the code in line by line intellisense may add extra brackets causing validation errors. You may want to paste the code into notepad first and then paste it into line 20.

     {
         "type": "Microsoft.Compute/virtualMachines/extensions",
         "name": "az104-08-vm1/customScriptExtension",

```
                 "vmSize": "Standard_DS1_v2"
```
Note: This section of the template defines the same Azure virtual machine size as the one you specified for the first virtual machine via the Azure portal.

On the Edit template blade, in the section displaying the content of the template, replace line 51 ("dataDisks": [ ] line) with the following code :

                 "dataDisks": [
                   {
                     "lun": 0,
                     "name": "az104-08-vm1-datadisk0",
                     "diskSizeGB": "1024",
                     "caching": "ReadOnly",
                     "createOption": "Empty"
                   },
                   {
                     "lun": 1,

                   }
                 ]

Note: If you are using a tool that pastes the code in line by line intellisense may add extra brackets causing validation errors. You may want to paste the code into notepad first and then paste it into line 49.

Note: This section of the template creates two managed disks and attaches them to az104-08-vm1, similarly to the storage configuration of the first virtual machine via the Azure portal.

Click Save and, back on the Custom deployment blade, click Review + Create and, on the Review + Create blade, click Create.

Note: Wait for the template deployment to complete. You can monitor its progress from the Disks blade of the az104-08-vm1 virtual machine. This should take no more than 3 minutes.
Back on the az104-08-vm1 blade, in the Operations section, click Run command, and, in the list of commands, click RunPowerShellScript.

On the Run Command Script blade, type the following and click Run to create a drive Z: consisting of the two newly attached disks with the simple layout and fixed provisioning:

New-StoragePool -FriendlyName storagepool1 -StorageSubsystemFriendlyName "Windows Storage*" -PhysicalDisks (Get-PhysicalDisk -CanPool $true)

New-VirtualDisk -StoragePoolFriendlyName storagepool1 -FriendlyName virtualdisk1 -Size 2046GB -ResiliencySettingName Simple -ProvisioningType Fixed

In the az10408vmss0 blade, in the Settings section, click Size.
In the list of available sizes, select Standard DS1_v2 and click Resize.
In the Settings section, click Instances, select the checkboxes next to the two instances of the virtual machine scale set, click Upgrade, and then, when prompted for confirmation, click Yes.
In the list of instances, click the entry representing the first instance and, on the scale set instance blade, note its Location (it should be one of the zones in the target Azure region into which you deployed the Azure virtual machine scale set).
Return to the az10408vmss0 - Instances blade, click the entry representing the second instance and, on the scale set instance blade, note its Location (it should be one of the other two zones in the target Azure region into which you deployed the Azure virtual machine scale set).
Return to the az10408vmss0 - Instances blade, and in the Settings section, click Scaling.
On the az10408vmss0 - Scaling blade, select the Custom autoscale option and configure autoscale with the following settings (leave others with their default values):

Click Add and, back on the az10408vmss0 - Scaling blade, specify the following settings (leave others with their default values):

Setting	Value
Instance limits Minimum	1
Instance limits Maximum	3

Click Save.
In the Azure portal, open the Azure Cloud Shell by clicking on the icon in the top right of the Azure Portal.
If prompted to select either Bash or PowerShell, select PowerShell.
From the Cloud Shell pane, run the following to identify the public IP address of the load balancer in front of the Azure virtual machine scale set az10408vmss0.
```
$rgName = 'az104-08-rg02'

$lbpipName = 'az10408vmss0-ip'

$pip = (Get-AzPublicIpAddress -ResourceGroupName $rgName -Name $lbpipName).IpAddress
```
From the Cloud Shell pane, run the following to start an infinite loop that sends the HTTP requests to the web sites hosted on the instances of Azure virtual machine scale set az10408vmss0.
```
while ($true) { Invoke-WebRequest -Uri "http://$pip" }
```
Minimize the Cloud Shell pane but do not close it, switch back to the az10408vmss0 - Instances blade and monitor the number of instances.

Note: You might need to wait a couple of minutes and click Refresh.
Once the third instance is provisioned, navigate to its blade to determine its Location (it should be different than the first two zones you identified earlier in this task.
Close Cloud Shell pane.

On the az10408vmss0 blade, in the Settings section, click Disks, click + Create and attach a new disk, and attach a new managed disk with the following settings (leave others with their default values):

Note: The disk attached in the previous step is a raw disk. Before it can be used, it is necessary to create a partition, create a filesystem, and mount it. To accomplish this, you will use Azure virtual machine Custom Script extension. First, you will need to remove the existing Custom Script Extension.
In the Settings section of the az10408vmss0 blade, click Extensions, click CustomScriptExtension, and then click Uninstall.

Note: Wait for uninstallation to complete.
In the Azure portal, open the Azure Cloud Shell by clicking on the icon in the top right of the Azure Portal.
If prompted to select either Bash or PowerShell, select PowerShell.
In the toolbar of the Cloud Shell pane, click the Upload/Download files icon, in the drop-down menu, click Upload and upload the file \Allfiles\Labs\08\az104-08-configure_VMSS_disks.ps1 into the Cloud Shell home directory.
From the Cloud Shell pane, run the following to display the content of the script:
```
Set-Location -Path $HOME

Get-Content -Path ./az104-08-configure_VMSS_disks.ps1
```
Note: The script installs a custom script extension that configures the attached disk.
From the Cloud Shell pane, run the following to excecute the script and configure disks of Azure virtual machine scale set:
```
./az104-08-configure_VMSS_disks.ps1
```
Close the Cloud Shell pane.
In the Settings section of the az10408vmss0 blade, click Instances, select the checkboxes next to the instances of the virtual machine scale set, click Upgrade, and then, when prompted for confirmation, click Yes.

Clean up resources

Note: Remember to remove any newly created Azure resources that you no longer use. Removing unused resources ensures you will not see unexpected charges.

Note: Don’t worry if the lab resources cannot be immediately removed. Sometimes resources have dependencies and take a longer time to delete. It is a common Administrator task to monitor resource usage, so just periodically review your resources in the Portal to see how the cleanup is going.

In the Azure portal, open the PowerShell session within the Cloud Shell pane.

Remove az104-08-configure_VMSS_disks.ps1 by running the following command:
```
rm ~\az104-08*
```
List all resource groups created throughout the labs of this module by running the following command:
```
Get-AzResourceGroup -Name 'az104-08*'
```
Delete all resource groups you created throughout the labs of this module by running the following command:
```
Get-AzResourceGroup -Name 'az104-08*' | Remove-AzResourceGroup -Force -AsJob
```
Note: The command executes asynchronously (as determined by the -AsJob parameter), so while you will be able to run another PowerShell command immediately afterwards within the same PowerShell session, it will take a few minutes before the resource groups are actually removed.

Review Questions

Can you enable ping requests between two Virtual Machines? What should you configure as the protocol?
If you configure NSG at the Virtual Network Level and NIC Level, which one will have the highest preference?
How are Network Security Group rules evaluated when communicating between Virtual Machines in different subnets?
What setting can you configure to create Virtual Machines on the same physical server?
