You can create a flat VDisk object and attach it to a virtual machine as a hard disk. After that, you can verify whether the operation was completed successfully.

Prerequisites
■

Verify that you are connected to a vCenter Server system.

■

Verify that you have access to at least one virtual machine host.

■

Verify that there is at least one datastore mounted on the virtual machine host.

Procedure
1

Mount the datastore on the virtual machine host and store the datastore in the $ds variable. 

$vmHost = Get-VMHost 'Host-A'
$ds = Get-Datastore -RelatedObject $vmHost
2

Create a flat, thin-provisioned virtual disk with 2-GB capacity on the $ds datastore. 

$vDisk = New-VDisk -Name 'VirtualDisk' -DiskType Flat -StorageFormat Thin -CapacityGB 2 -Datastore $ds
3

Create a virtual machine named VirtualMachine with one hard disk and store this virtual machine in the $vm variable. 

$vm = New-VM -Name 'VirtualMachine' -VMHost 'Host-A' -Datastore $ds -DiskMB 512
4

Power on the $vm virtual machine. 

Start-VM -VM $vm
5

Attach the VDisk object to the $vm virtual machine. 

New-HardDisk -VM $vm -VDisk $vDisk
6

Verify that the VDisk object has been attached and the virtual machine now has two hard disks. 

Get-HardDisk -VM $vm
