How programatically restart a Azure VM role (PaaS VM) - azure

Question

I have a PaaS VM role that need to be restart using Azure Management libraries. I tried following codes but failed with "BadRequest: The operation is not supported on a role of type MyPaaSVmName". But I successfully restarted IaaS VM using below Method1.
Is it possible to restart a PaaS VM role using Azure Management Libraries?
if not, is there any other way to achieve it using c#.
1.
ComputeManagementClient client = new ComputeManagementClient(cloudCredentials);
client.VirtualMachines.Restart(hostedServiceName, deploymentName, vmName);
2.
ComputeManagementClient client = new ComputeManagementClient(cloudCredentials);
VirtualMachineOperationsExtensions.Restart(client.VirtualMachines, hostserviceName, deploymentName, vmName);
Thank you.

Answer 1

Found the issue,
Method1 should be like this as I am restarting a Role Instance. Method2 is wrong.
client.Deployments.RebootRoleInstanceByDeploymentName(hostserviceName, deploymentName, roleName);

Here's how you can do it using Azure Powershell:
ReSet-AzureRoleInstance -ServiceName "MySvc1" -Slot Staging -InstanceName "MyWebRole_IN_0" –reboot
https://msdn.microsoft.com/en-us/library/azure/dn495202.aspx
And here's a snippet from an Azure Automation Runbook which can reboot all cloud service's instances, per update domain (so you have no downtime):
https://gallery.technet.microsoft.com/Reboot-Cloud-Service-PaaS-b337a06d
$roleInstances = Get-AzureRole -ServiceName $cloudServiceName -Slot Production -InstanceDetails
Write-Output "Retrieved all role instances for cloud service: $cloudServiceName. Number of instances: " + $roleInstances.Count
# Group instances per update domain
$roleInstanceGroups = $roleInstances | Group-Object -AsHashTable -AsString -Property InstanceUpgradeDomain
Write-Output "Number of update domains found: " + $roleInstanceGroups.Keys.Count
# Visit each update domain
foreach ($key in $roleInstanceGroups.Keys)
{
$count = $perDomainInstances.Count;
Write-Output "Rebooting $count instances in domain $key"
$perDomainInstances = $roleInstanceGroups.Get_Item($key)
foreach -parallel($instance in $perDomainInstances)
{
$instanceName = $instance.InstanceName
Write-Output "Rebooting instance $instanceName"
Reset-AzureRoleInstance -ServiceName $cloudServiceName -Slot Production -InstanceName $instanceName -Reboot -ErrorAction Stop
}
}
