Adding VM to existing DRS rule?

[JasonMLehman]

Has anyone successfully modifed an existing DRS rule and added a new VM to a rule?  I can add a new one with a duplicate name, but I cannot seem to modify an existing rule.  If I run the following it does nothing to the DRS rule.

var antiaffinitySpec = new VcClusterAntiAffinityRuleSpec()
antiaffinitySpec.enabled = true
antiaffinitySpec.name = rulename
antiaffinitySpec.userCreated = true
antiaffinitySpec.vm = groupArray

var clusterRuleSpec = new Array(new VcClusterRuleSpec());
clusterRuleSpec[0] = new VcClusterRuleSpec()

// If I change this to VcArrayUpdateOperation.add it will add a rule with a duplicate name
clusterRuleSpec[0].operation = VcArrayUpdateOperation.edit;
clusterRuleSpec[0].info = antiaffinitySpec;

var clusterConfigSpec = new VcClusterConfigSpecEx();
clusterConfigSpec.rulesSpec = clusterRuleSpec;

att_task = cluster.reconfigureComputeResource_Task(clusterConfigSpec, true);

var affinitySpec = new VcClusterAntiAffinityRuleSpec()

affinitySpec.enabled = true

affinitySpec.name = rulename

affinitySpec.userCreated = true

affinitySpec.vm = groupArray

 

var clusterRuleSpec = new Array(new VcClusterRuleSpec());

clusterRuleSpec[0] = new VcClusterRuleSpec()

clusterRuleSpec[0].operation = VcArrayUpdateOperation.remove;

clusterRuleSpec[0].info = affinitySpec;

 

var clusterConfigSpec = new VcClusterConfigSpecEx();

clusterConfigSpec.rulesSpec = clusterRuleSpec;

//clusterConfigSpec.groupSpec =clusterGroupSpec;

 

//clusterConfigSpec.groupSpec[0].operation = VcArrayUpdateOperation.edit

 

att_task = cluster.reconfigureComputeResource_Task(clusterConfigSpec, true);

You don't need to modify the rule necessarily unless you are adding another vm or host group to the rule.  We just add the vm to the vm group specified in the rule.  There are canned workflows for this.  I ended up writing my own action based on the canned stuff that works a bit more to my personal taste.  I'll attach it.

This is the workflow you can use to add VMs to an existing VM Group: "Add virtual machines to DRS group"

A bit late but I just started using this product and needed to do this. I am adding VMs that get deployed to a DRS group using powershell in Action Based Extensibility:

Set-PowerCLIConfiguration -InvalidCertificateAction Ignore -Confirm:$false
Connect-VIServer -Server vsphere.corp.com -User $vsphereUser -Password $vspherePass
function handler($context, $inputs) {
   # Hostname generated during abx static name creation
   $vm_name = $inputs.customProperties.vmname
   Get-DrsClusterGroup "group_name" | Set-DrsClusterGroup -VM $vm_name -Add
   # Return updated outputs object containing hostname deployment process
   return $vm_name
}
