DRS-Rule Type "Run VMs on Hosts" on/off

[DCSRostock]

if I try to turn off a rule beginning with A_ (for automated) with

$rules = Get-Cluster -Name $cluster | Get-DrsRule -Name "A_*"
foreach($rule in $rules) {
  Set-DrsRule -Rule $rule -Enabled:$false -Confirm:$false

}

I get the error

Set-DrsRule : 01.02.2011 10:04:29    Set-DrsRule        Not initialized: vim.VirtualMachine[] vm   
At C:\Program Files (x86)\VMware\Infrastructure\vSphere PowerCLI\Scripts\DPM_test.ps1:91 char:22
+           Set-DrsRule <<<<  -Rule $rule -Enabled:$false -Confirm:$false
    + CategoryInfo          : NotSpecified: (:) [Set-DrsRule], InvalidRequest
    + FullyQualifiedErrorId : Client20_MoServiceImpl_Invoke_ViError,VMware.VimAutomation.ViCore.Cmdlets.Commands.SetDrsRule

But this type of rule has no direct affinity to a vm? Who can help?

Did you try running this in 32-bit mode ?

See Issue in New-OSCustomizationSpec in Power CLI 4.1.1 on how to do this.

Try this:

foreach ($rule in $rules)
    {foreach ($vmid in $rule.VMIDs)
        {$vm = get-vm -ID $vmid
         Set-DrsRule -Rule $rule -vm $vm -Enabled:$false -Confirm:$false }
    }

Please note - NO VC close - so untested (but I think it should work)

I have installed V4.1.0.2519 and start the powershell_ise.exe from  c:\Windows\System32\WindowsPowerShell\v1.0 on W2k8r2. Should be  32-bit-mode.

I think you need to start like this for 32-bit.

C:\Windows\SysWOW64\WindowsPowerShell\v1.0\powershell.exe

In my rules "Run VMs on Hosts" the VMIDs are empty.

Hi LucD,

yes of course. The result is the same.

Let's have a look at your rules.

Can you do ?

Get-Cluster -Name $cluster | Get-DrsRule -Name "A_*" | Select *

Hi LucD,

It looks as if you are using ESX(i) pre-4.1

I tested against ESX 4.1 where it works without a problem.

It could be a problem with the specific ESX version.

Perhaps someone from the Development Team can have a look ?

Hi LucD,

using VSphere Server 4.1.0 Build 258902, the last official version?!?

Best regards

[LucD]

Then it must be the PowerCLI version we are using.

Look at the type of the Extensiondata

Name          : Some servers
Enabled       : True
ClusterId     : ClusterComputeResource-domain-c5
Cluster       : MyCluster
ClusterUid    : /VIServer=@xxxxxxx:443/Cluster=ClusterComputeResource-domain-c5/
KeepTogether  : False
VMIds         : {VirtualMachine-vm-33540, VirtualMachine-vm-18923, VirtualMachine-vm-36303}
Uid           : /VIServer=@xxxxxxxx:443/Cluster=ClusterComputeResource-domain-c5/DrsVMAffinityRule=70/
ExtensionData : VMware.Vim.ClusterAntiAffinityRuleSpec

I'm using

Same with the newer version.

Hi LucD,

your example show a "Run VMs on Hosts"-Rule? I my case the VMID's field are empty. That's is the problem maybe. I have create a DRS-VM-group an a DRS-hostgroup put it tigether with "Run VMs on Hosts".

Best regards

[LucD]

I created a test rule based on groups and now I see the same error you are seeing.

It seems you discovered a bug with rules that use DRS groups.

Let me see if I can find a bypass.

[LucD · Accepted solution]

This should do the trick

$clusterName = "MyCluster" 
$cluster = Get-Cluster -Name $clusterName 
$rules = Get-DrsRule -Name "A_*" -Cluster $cluster 
if($rules){
    $spec =New-Object VMware.Vim.ClusterConfigSpec
    foreach($rule in $rules) {
        $RulesSpec = New-Object VMware.Vim.ClusterRuleSpec
        $RulesSpec.Info = $rule.ExtensionData
        $RulesSpec.Info.Enabled = $false
        $RulesSpec.Operation = "edit"
        $spec.rulesSpec += $RulesSpec
    }
    $cluster.ExtensionData.ReconfigureCluster($spec,$true)
}

Hi,

I can confirm that Drs rules "Run VMs on Hosts" are not supported in PowerCLI 4.1.1. I've already file a bug for this issue.

Thanks for the feedback.

P.S I think Luc's workaround should work also.

[DCSRostock]

Thank you LucD, it works.
