Hi there, I have a worfklow where I modified the basic Clone VM WF to clone my VM to a set of datastores based on the disk. I have a step in the workflow that determines which disk goes where, then passes into a final script that is supposed to build the StoragePlacementSpec. It all looks correct to me, given the documentation and examples I can find. However, I always get the following error after the applyStorageDrsRecommendation_Task call:
Task 'ApplyStorageDrsRecommendation_Task' error: A specified parameter was not correct. Key does not match StoragePlacementSpec.podSelectionSpec.initialVmConfig (Dynamic Script Module name : vim3WaitTaskEndDrs#27)
The error doesn't' make any sense to me.
Here is the script I'm using:
System.log("Source VM: " + vm.name);
System.log("New VM Name: " + vmName);
System.log("Target VM Host: " + targetVmHost.name);
// Setup the hard disk mappings:
var defaultDatastoreCluster = initialVmConfig.vmxDatastoreCluster;
// Setup the Storage Specification:
var storageSpec = new VcStoragePlacementSpec();
storageSpec.type = "clone";
storageSpec.vm = vm;
storageSpec.cloneSpec = cloneSpec;
storageSpec.cloneName = vmName;
storageSpec.podSelectionSpec = new VcStorageDrsPodSelectionSpec();
storageSpec.podSelectionSpec.storagePod = defaultDatastoreCluster;
var placementArray = [];
if ( initialVmConfig.initialVmConfig != null && initialVmConfig.initialVmConfig.length > 0 )
{ for each ( plc in initialVmConfig.initialVmConfig ) { placementArray.push(plc); }
}
else
{ System.debug("No disks specified."); // Default placement of all VM disks in the same DS Cluster: var placement = new VcVmPodConfigForPlacement(); placement.storagePod = defaultDatastoreCluster; placementArray.push(placement);
}
// You have to assign a filled array object to this property, you can't just initialize an empty array and add elements to it for some reason:
storageSpec.podSelectionSpec.initialVmConfig = placementArray;
System.debug("VM File DatastoreCluster: " + storageSpec.podSelectionSpec.storagePod.name);
System.debug("StorageSpec InitialConfig: " + storageSpec.podSelectionSpec.initialVmConfig);
if ( storageSpec.podSelectionSpec.initialVmConfig )
{
System.debug("StorageSpec InitialConfig Length: " + storageSpec.podSelectionSpec.initialVmConfig.length.toString()); for each ( plc in storageSpec.podSelectionSpec.initialVmConfig ) { System.debug("Disk: " + plc.disk[0].diskId + " will be created in DatastoreCluster " + plc.storagePod.name); }
}
if ( !vmFolder )
{
// Default to "Discovered Virtual Machines": vmFolder = System.getModule("com.plex.vco").getVmFolderByName("Discovered Virtual",vCenterSdkConnection)[0];
}
storageSpec.folder = vmFolder;
if ( targetVmHost != null )
{
storageSpec.host = targetVmHost;
}
// Get the DRS Recommendations for disk placement:
var managedObject = vm.sdkConnection.storageResourceManager;
var myVcStoragePlacementResult = VcStoragePlacementResult();
myVcStoragePlacementResult = managedObject.recommendDatastores(storageSpec);
// Apply the DRS Recommendations:
var myKey = new Array();
myKey[0] = myVcStoragePlacementResult.recommendations[0].key;
myVcTask = managedObject.applyStorageDrsRecommendation_Task(myKey);
return myVcTask;
In this script, I'm passing in an array of VcVmPodConfigForPlacementObjects to build the initialConfig. Each placement has a disk locator defined and it's target datastore defined. Here is that code:
var vmDiskAssignments = diskAssignmentResultPowershellObject.getRootObject();
var vmConfig =
{
initialVmConfig : [], vmxDatastoreCluster : null
};
// Assign disk relocaton specification:
for each ( da in vmDiskAssignments )
{
var datastoreCluster = da.getProperty("Target"); var diskId = Number(da.getProperty("DiskId")); var datastoreClusterVcoObject = System.getModule("com.plex.vco").getVcoObjectByPowerShellObject(datastoreCluster); if ( diskId > 0 ) { // Add the disk mapping to the initial config: var locator = new VcPodDiskLocator(); locator.diskId = diskId; var placement = new VcVmPodConfigForPlacement(); placement.disk = [locator]; placement.storagePod = datastoreClusterVcoObject; vmConfig.initialVmConfig.push(placement); } else { // Add the vmx file location: vmConfig.vmxDatastoreCluster = datastoreClusterVcoObject; }
}
return vmConfig;
Here is the output I get from VCO:

Most of the examples I see show people cloning a VM and all of it's disks to a single DS Cluster, so they're only partially helpful. Does anyone have any idea where I'm off the track? Thanks!
