Hello,

if you want to list all the powered-on virtual machines without vmware tools installed, you can use this powercli script:

 

# Change the value of this variable (regular expression), if you would want just some datastores (not all) from the script's output

$datastores=".+"

 

get-vm | where-object {$_.powerstate -ne "PoweredOff" } | % { get-view $_.ID } | where-object { ($_.Datastore -match $datastores) -and ($_.guest.toolsstatus -Notmatch ".*Ok.*") } | select Name

 

(Remember to use the Connect-VIServer cmdlet before!)

 

The script is based in this script.

 

 

Best regards,

Hello,

if you want to add a new vdisk (vmdk file) to a running virtual machine, you can do it via command line.

 

First, connect to the esxi host where is the placed the vm that you want to add a new vdisk/vmdk.

 

Then go to the datastore where you want to place the new vdisk/vmdk:

cd /vmfs/volumes/WhatEverDatastore/

 

Then create the vmdk file using vmkfstools:

vmkfstools -c 150G --diskformat zeroedthick vDisk.vmdk

 

Finally, add the new vdisk to the virtual machine:

 

First, get the vmid of the virtual machine:

 

vim-cmd vmsvc/getallvms

 

With the vmid, add the vdisk/vmdk:

 

vim-cmd vmsvc/device.diskaddexisting 464 /vmfs/volumes/WhatEverDatastore/vDisk.vmdk 0 3

 

 

Best regards,

Pablo

P.D: If you want a linux virtual machine be able to detect the new vDisk, check this.

Hello,

searching the web, a found a nice script that reports orphaned/unused vmdk files:

Virtually Jason: Orphaned VMDK Files

 

It works so fine, but if do the bad praxis of having datastores with the same name in different vmware hosts, then it doesn't work.

 

I have modified the script to make it work in this kind of environments:

 

$report = @()

$arrUsedDisks = Get-View -ViewType VirtualMachine | % {$_.Layout} | % {$_.Disk} | % {$_.DiskFile}

$arrHost = Get-VMHost

 

foreach ($vmhost in $arrHost) {

 

$arrDS = Get-Datastore -VMHost $vmhost | Sort-Object -property Name

foreach ($strDatastore in $arrDS) {

#Write-Output "$($strDatastore.Name) in $host.Name Orphaned Disks:"

$ds = Get-Datastore -Name $strDatastore.Name -VMHost $vmhost | % {Get-View $_.Id}

$fileQueryFlags = New-Object VMware.Vim.FileQueryFlags

$fileQueryFlags.FileSize = $true

$fileQueryFlags.FileType = $true

$fileQueryFlags.Modification = $true

$searchSpec = New-Object VMware.Vim.HostDatastoreBrowserSearchSpec

$searchSpec.details = $fileQueryFlags

$searchSpec.matchPattern = "*.vmdk"

$searchSpec.sortFoldersFirst = $true

$dsBrowser = Get-View $ds.browser

$rootPath = "[" + $ds.Name + "]"

$searchResult = $dsBrowser.SearchDatastoreSubFolders($rootPath, $searchSpec)

 

 

foreach ($folder in $searchResult)

{

foreach ($fileResult in $folder.File)

{

if ($fileResult.Path)

{

$pathAsString = out-string -InputObject $FileResult.Path

if (-not ($arrUsedDisks -contains ($folder.FolderPath + $fileResult.Path))){

# Changed Black Tracking creates ctk.vmdk files that are not referenced in the VMX.  This prevents them from showing as false positives.

if (-not ($pathAsString.toLower().contains("-ctk.vmdk"))){

$row = "" | Select VMHost, DS, Path, File, SizeGB, ModDate

$row.VMHost = $vmhost.Name

$row.DS = $strDatastore.Name

$row.Path = $folder.FolderPath

$row.File = $fileResult.Path

$row.SizeGB = (($fileResult.FileSize/1024)/1024)/1024

$row.ModDate = $fileResult.Modification

$report += $row

#Write-Output "$($row.Path)$($row.File)"

}

}

}

}

}

}

}

 

 

$report

Have fun!

If you want get the RDMs defined in your vmware environment using PowerCLI, then you can just use this:

 

 

$allvms = Get-VM

 

foreach ($vm in $allvms) {

  

    $vmrdm = Get-HardDisk -VM $vm -DiskType "RawPhysical","RawVirtual"

  

    foreach ($rdm in $vmrdm) {

  

        if ($rdm.Name) {

        $row = "" | select Parent,Name,DiskType,ScsiCanonicalName,DeviceName,FileName,CapacityGB

      

        $row.Parent = $rdm.Parent

        $row.Name = $rdm.Name

        $row.DiskType = $rdm.DiskType

        $row.ScsiCanonicalName = $rdm.ScsiCanonicalName

        $row.DeviceName = $rdm.DeviceName

        $row.FileName = $rdm.FileName

        $row.CapacityGB = ($rdm.CapacityKB/1024)/1024

      

      

      

        $report += $row } # End if ($rdm.Name)

 

                  

} # End foreach ($rdm in $vmrdm)

 

 

} # End foreach ($vm in $allvms)

 

 

 

$report
