I'm creating a script that gets all vm's and shows the DiskSpace. THe Problem is, that if a vm is powered off, it won't show the uesed Space of a disk.

Here are two examples: First one with an VM that is powered on:

PowerCLI C:\> Get-VM sluwv0039

Name                 PowerState Num CPUs MemoryGB
----                 ---------- -------- --------
sluwv0039            PoweredOn  2        4.000

PowerCLI C:\> $VM = Get-VM sluwv0039
PowerCLI C:\> $VM.guest.disks

CapacityGB      FreeSpaceGB     Path
----------      -----------     ----
49.997          5.417           C:\

Example two where the VM is powered off:

PowerCLI C:\> Get-VM sluwv0012

Name                 PowerState Num CPUs MemoryGB
----                 ---------- -------- --------
sluwv0012            PoweredOff 4        8.000


PowerCLI C:\> $VM = Get-VM sluwv0012
PowerCLI C:\> $VM.guest.disks
PowerCLI C:\>

Note: The Last line is the output. There is no "CapacityGB" etc.

Correct, that property is reading from the guest file system to see how much space is left on the partition. In your case, the C:\ drive. If the VM is off, there's no way for PowerCLI to find that property.

Alternatively, you could look at the $vm.ExtensionData.Summary.Storage properties and do some rough conversions. Note: the output of those are in byte, so you'll want to convert them to GB. Example: $tempVM.ExtensionData.Summary.Storage.Committed / 1GB

It won't be exact, but it will be better than no output at all.

here is example of script to show vm specification:

Get-Vm | Select-Object Name,PowerState,VMHost,NumCPU,MemoryGB,ProvisionedSpaceGB,@{N="HostName";E={@($.guest.HostName)}},@{N="Gateway";E={@($.ExtensionData.Guest.IpStack.IpRouteConfig.IpRoute.Gateway.IpAddress[0])}},@{N="DNS";E={$.ExtensionData.Guest.IpStack.DnsConfig.IpAddress}},@{N="IPAddress";E={@($.guest.IPAddress -like "192.168.*")}},@{N="Nics";E={@($.guest.Nics)}},@{N="Datastore";E={@($ | Get-DataStore)}},@{N="Disks";E={@($.guest.Disks)}},Version,@{N="State";E={@($.guest.State)}},@{N="OS";E={@($_.guest.OSFullName)}}

the sample output is like this:

Name State VMHost NumCpu MemoryGB PowerState ProvisionedSpaceGB Version IPAddress HostName OS Nics Disks VMwareTools Gateway DNS test Running 192.168.32.100 2 1 PoweredOn 43.1085147 v8 192.168.122.1 Elenoon Ubuntu Linux (64-bit) Network adapter 1:VM Network Network adapter 2:local : : Capacity:17167286272, FreeSpace:14212493312, Path:/ Capacity:15188623360, FreeSpace:15154872320, Path:/media/files Capacity:10724835328, FreeSpace:10672824320, Path:/var/log Capacity:973770752, FreeSpace:690139136, Path:/boot guestToolsRunning 127.0.0.1

hope to be useful ;)
