Apply AntiAffinity rule to a new vm

[tdburgess]

I am having a hard time setting the antiaffinity rule on new vm builds with powercli.

I keep getting this error:

New-VM Invalid disk identifier '1' in S drsVMDiskAntiAffinityRule. Please  specify a correct disk identifier when creati ng the SdrsVMDiskAntiAffinityRule  (by passing the HardDisk object(s)).

here is the code:

$advancedOption = New-object 'VMware.VimAutomation.ViCore.Types.V1.DatastoreManagement.SdrsVMDiskAntiAffinityRule' 1,2

$DSCluster = Get-datastorecluster -name $DStore; New-VM -Name $vmname -advancedoption $advancedoption -OSCustomizationSpec $Customization -Template $Template -VMhost $VMHost -Datastore $DSCluster -RunAsync

I have tried it with a template that 1 disk or 2 disks and I get hte same result.

Thanks for any help!

here is the option for $advancedoption

DiskIdentifier
--------------
{1, 2}

That seems to work for me when I don't use a template.

Is that working for you as well ?

Is the datastorecluster enabled for SDRS ?

$datastoreCluster = Get-DatastoreCluster -Name DSC1 
$advancedOption = New-Object 'VMware.VimAutomation.ViCore.Types.V1.DatastoreManagement.SdrsVMDiskAntiAffinityRule' 1,2
New-VM -Name TestVM -DiskMB 40000,40000,40000 -Datastore $datastoreCluster -AdvancedOption $advancedOption -VMHost (Get-VMHost MyEsx)

that works for me too.

the datastore cluster is enabled for SDRS.

Will the advanced options not work with a template? or do i need to modify the template?

I'm afraid I don't know, I'll have to play around with anti-affinity rules and templates myself a bit.

Is there a way to set the default vmdk affinity rule to false on the datastore cluster?  We disabled it for the vm affinity rule and i am able to clone from a template.  The Vm affinity rule is disabled so no sdrs rules got applied, but keep vmdk's together option is still checked for the vm on the cluster.

any thoughts?
