  • 1.  How to get Used Harddisk space + RDM Space of a VM

    Posted Aug 17, 2015 05:24 PM

    Hi All,

    I would like to know, harddisk space used by VM both RDM + VMDK

    I am getting the details using the below script,

    Get-VM | Get-HardDisk |

    Select @{N='VM Name';E={$_.Parent.Name}},

    @{N="IP Address";E={@($_.Parent.guest.IPAddress[0])}},

    @{N="VM PowerState";E={@($_.Parent.PowerState)}},

    @{N="CPU Count";E={@($_.Parent.NumCPU)}},

    @{N="MemoryInGB";E={@($_.Parent.MemoryGB)}},

    @{N="Cluster";E={Get-Cluster -VM $_.Parent}},

    @{N="ESX Host";E={Get-VMHost -VM $_.Parent}},

    @{N="Folder";E={$_.Parent.Folder.Name}},

    @{N='HD Capacity';E={$_.CapacityGB}},

    @{N="Datastore";E={Get-Datastore -VM $_}},

    I am looking for similar output as below

    VM Name     IP Address     VM PowerState     CPU Count     MemoryinGB     Cluster     ESXHost     Folder     HD Capacity(VMDK+RDM)     Datastore

    VM1             10.10.10.10     PoweredON          4                    8                       ABC      11.11.11.11   ABC         2048                                   Datastore 1

    VM2          10.10.10.11   PoweredON        4                   8                    ABC      11.11.11.13   ABC         3096                                 Datastore 2

    Hi LucD,

    Thanks for your reply. I want the total harddisk space used by a VM which included VMDK + RDM

    But the above link splits the details, which I dont need.

    Example :

    VM1      800 GB

    VM2      1300 GB

    If you just want the configured disk size (i.e. not the amount actually used)

    Get-VM  |

        Select @{N='VM Name';E={$_.Name}},

        @{N="IP Address";E={@($_.guest.IPAddress[0])}},

        @{N="VM PowerState";E={@($_.PowerState)}},

        @{N="CPU Count";E={@($_.NumCPU)}},

        @{N="MemoryInGB";E={@($_.MemoryGB)}},

        @{N="Cluster";E={Get-Cluster -VM $_}},

        @{N="ESX Host";E={Get-VMHost -VM $_}},

        @{N="Folder";E={$_.Folder.Name}},

        @{N='HD Capacity';E={[Math]::Round(((Get-HardDisk -VM $_ | Measure-Object -Property CapacityGB -Sum).Sum),2)}},

        @{N="Datastore";E={Get-Datastore -VM $_}}
