The current virtual disk format of the template is “Thin provision” and It must be converted to “Thick Provision Lazy Zeroed” after cloning

Hi all,

Recently I have developed a VMware automation tool deploying Virtual Machine from a template through vSphere SDK

The current virtual disk format of the template is “Thin provision” and It must be converted to “Thick Provision Lazy Zeroed” after cloning

I have tried many different ways but I have not resolved the issue.

Could anyone help me to convert the existing virtual disk format through vSphere SDK?

$diskfileBacking = new VirtualDiskFlatVer2BackingInfo();

$diskfileBacking->fileName = '[Test] RHEL 6.6 Non-Prod/RHEL 6.6 Non-Prod.vmdk';

$diskfileBacking->diskMode = "persistent";

$diskfileBacking->thinProvisioned = false;

$desc = new Description();

$desc->label = "testvm_disk_0";

$desc->summary = "Disk 0";

$disk = new VirtualDisk();

$disk->capacityInKB = '58720256';

$disk->controllerKey = 1000;

$disk->unitNumber = 0;

$disk->backing = $diskfileBacking;

$disk->key = 2000;

$disk->deviceInfo = $desc;

$spec = new VirtualDeviceConfigSpec();

$spec->operation = 'edit';

$spec->device = $disk;

Regards
