How to Display Information About FileName of a Disk?

[haripetrov]

I am trying to obtain information about all disks which are using "nonpersistent" mode with Get-View. Everything is working with the exception of @{N="Filename";E={$vm.Config.Hardware.Device.Backing.FileName}}

$VMs = Get-View -ViewType VirtualMachine | Where {-not $_.Config.Template}

$Result = @(ForEach ($vm in $VMs){

    $vdisk = $vm.Config.Hardware.Device | where {$_ -is [VMware.Vim.VirtualDisk] -and ($_.Backing.DiskMode -eq "nonpersistent" -or $_.Backing.DiskMode -eq "independent_nonpersistent")}

    if ($vdisk){

        $vdisk | Select @{N="VM";E={$vm.Name}},

            @{N="NonPersistentMode";E={$_.DeviceInfo.Label}},

            @{N="CapacityGB";E={$_.capacityInKB/1024/1024}},

            @{N="Filename";E={$vm.Config.Hardware.Device.Backing.FileName}}

    }

})

$Result

This script is originally inspired by this one:

Get-VM | % { Get-HardDisk -VM $_ | Where {$_.Persistence -eq "IndependentPersistent" -or $_.Persistence -eq "IndependentNonPersistent"} } | Select Parent, Name, CapacityGB, Filename, DiskType, Persistence, ScsiCanonicalName | Export-CSV VMs_Persistent_Mode.csv -NoTypeInformation -UseCulture

I can see that in https://www.vmware.com/support/developer/vc-sdk/visdk41pubs/ApiReference/vim.vm.device.VirtualDevice... we have property "FileName" but I don't know how to call it in this case.

The Device property is an array, so you will have to find the correct entry.

Perhaps based on the Label, something like this

$hd = $vm.Config.Hardware.Device | where{$_.Info.Label -eq 'Hard Disk 1'}

I will continue to search for this information.

Let me know if you can find it, otherwise I can give you a sample script.

[haripetrov]

I have not managed to find the information so far. I would appreciate it if you could share your sample script here.

P.S. Would it be possible for you to tell me how you format your code in this way (using color format)?

[LucD · Accepted solution]

Try something like this

$diskModes = [VMware.Vim.VirtualDiskMode]::independent_nonpersistent,[VMware.Vim.VirtualDiskMode]::nonpersistent

foreach($vm in (Get-View -ViewType VirtualMachine -Property Name,Config.Hardware.Device -Filter @{'Config.Template'='False'})){

  $vm.Config.Hardware.Device |

  where{$_ -is [VMware.Vim.VirtualDisk] -and $diskModes -contains $_.Backing.DiskMode} |

  Select  @{N="VM";E={$vm.Name}},

    @{N="Disk";E={$_.DeviceInfo.Label}},

    @{N="Mode";E={$_.Backing.DiskMode}},

    @{N="CapacityGB";E={$_.capacityInKB/1MB}},

    @{N="Filename";E={$_.Backing.FileName}}

}

To get the syntax highlighted code, I currently use the PowerShell ISE addon from Windows PowerShell V3 ISE: Copy As HTML Add-On

Thank you, again. The script is working as expected.

I will try this addon in question.
