Open PowerCLI console and connect to the vCenter where the VM is located. Then, we will retrieve the VM we want to modify and store it is a variable.
#Connect to vCenter Connect-VIServer -Server vcenter.example.com #Get the VM and store it in a variable $vm = Get-VM MyVM
Lets examine the VM’s hard disks. There are two of them.
Get-HardDisk $vm CapacityGB Persistence Filename ---------- ----------- -------- 36.000 Persistent [Datastore] MyVM/MyVM.vmdk 5.000 Persistent [Datastore] MyVM/MyVM_1.vmdk
Now, we will add a new disk of size 10 GB.
$vm | New-HardDisk -CapacityGB 10 CapacityGB Persistence Filename ---------- ----------- -------- 10.000 Persistent [Datastore] MyVM/MyVM_4.vmdk
To reflect the changes to the VM, we need to refresh the variable. Then, we will list the disks again. Notice the new disk we added.
$vm = Get-VM MyVM Get-HardDisk $vm CapacityGB Persistence Filename ---------- ----------- -------- 36.000 Persistent [Datastore] MyVM/MyVM.vmdk 5.000 Persistent [Datastore] MyVM/MyVM_1.vmdk 10.000 Persistent [Datastore] MyVM/MyVM_4.vmdk
Finally, we will remove the disk we just added.
Get-HardDisk -VM $vm | Where-Object {$_.Filename -like "*MyVM_4*"} | Remove-HardDisk
Verify again
$vm = Get-VM MyVM Get-HardDisk $vm CapacityGB Persistence Filename ---------- ----------- -------- 36.000 Persistent [Datastore] MyVM/MyVM.vmdk 5.000 Persistent [Datastore] MyVM/MyVM_1.vmdk
