set DRS options for VMs

[mal_michael]

hi,

i read the post Modify HA virtual machine options for guests and want to set drs options in similiar way (because set-vm is buggy).

what i did is:

function Set-DRSAutomationLevel

{

param($cluster, $vm, $DRSAutomationLevel)

$cluster_view = Get-View -ViewType ClusterComputeResource -Filter @{"Name" = $cluster}

$vm_view = Get-View -ViewType VirtualMachine -Filter @{"Name" = $vm}

$operation = "add"

if($cluster_view.ConfigurationEx.DrsVmConfig -ne $null)

{

foreach($guest in $cluster_view.ConfigurationEx.DrsVmConfig)

{

if($guest.Key.Value -eq $vm_view.MoRef.Value)

{

$operation = "edit"

}

}

}

$spec = New-Object VMware.Vim.ClusterConfigSpec

$VMspec = New-Object VMware.Vim.ClusterDrsVmConfigSpec

$VMspec.operation = $operation

$VMspec.Info = New-Object VMware.Vim.ClusterDrsVmConfigInfo

if ($DRSAutomationLevel -like "disabled")

{

$VMspec.Info.Enabled = $false

}

#elseif ($DRSAutomationLevel -like "default")

#{

#TBD

#}

else

{

$VMspec.Info.Enabled = $true

$VMspec.Info.Behavior = $DRSAutomationLevel

}

$VMspec.Info.Key = $vm_view.MoRef

$spec.DrsVmConfigSpec = @($VMspec)

$task = Get-View ($cluster_view.ReconfigureCluster_Task($spec, $true))

while($task.Info.Status -eq "running" -or $task.Info.Status -eq "queued")

{

$task.UpdateView()

}

}

everything is working fine (thanks LucD), but i don't no how to set drs level to default (cluster setting).

my understanding is that i need to remove custom setting of VM (if exists already) , but i don't no how to do that.

any help appreciated,

thanks

This post should help: http://communities.vmware.com/thread/197308. Basically, you need to set the Behavior option to default.

[mal_michael]

valid options for behavior are : fullyAutomated, partiallAutomated, manual

there is no "default".

if no custom option is specified, then vm uses default cluster setting. so you (well, actually I :smileyblush: ) need to delete this custom setting.

the question is how...

Hi,

To removed VM custom setting you need just to delete the entry for that vm setting ClusterDasVmConfigSpec.operation to "remove" and passing VM's MoRef as removeKey:

function Set-DRSAutomationLevel{
	param($cluster, $vm, $DRSAutomationLevel)
	$cluster_view = Get-View -ViewType ClusterComputeResource -Filter @{"Name" = $cluster}
	$vm_view = Get-View -ViewType VirtualMachine -Filter @{"Name" = $vm}
	$operation = "add"
	
	if($cluster_view.ConfigurationEx.DrsVmConfig -ne $null) {
		foreach($guest in $cluster_view.ConfigurationEx.DrsVmConfig) {
			if($guest.Key.Value -eq $vm_view.MoRef.Value){
				if ($DRSAutomationLevel -like "default") {
					# remove the custom DRS setting for that VM
					$operation = "remove"
				} else {
					$operation = "edit"
				}
			}
		}
	}
	
	if (($DRSAutomationLevel -like "default") -and ($operation -like "add")) {
		# if there is no VM specific DRS setting - do nothing
	}else {
		$spec = New-Object VMware.Vim.ClusterConfigSpec
		$VMspec = New-Object VMware.Vim.ClusterDrsVmConfigSpec
		$VMspec.operation = $operation
		$VMspec.Info = New-Object VMware.Vim.ClusterDrsVmConfigInfo
		if ($DRSAutomationLevel -like "disabled"){
			$VMspec.Info.Enabled = $false
			$VMspec.Info.Key = $vm_view.MoRef
		}elseif ($DRSAutomationLevel -like "default"){
			$VMspec.removeKey = $vm_view.MoRef
		}else {
			$VMspec.Info.Enabled = $true
			$VMspec.Info.Behavior = $DRSAutomationLevel
		}
	
		$VMspec.Info.Key = $vm_view.MoRef
		$spec.DrsVmConfigSpec = @($VMspec)
		$cluster_view.ReconfigureCluster($spec, $true)
	}
}

In addition "view" object have "blocking" task methods that will wait for task completion for you (i.e ReconfigureCluster instead of ReconfigureCluster_Task)
