Removal of hardware store unwanted VM, while it is powered. -questions

So while trying to work/modify scripts already exist; to identify and "clean up if possible" unwanted material (series, USB, etc...) If some problems of type gotcha. * Previous scripts based on http://communities.vmware.com/thread/137257 - $VM. ReconfigVM_Task ($Spec)

If the target VM has unwanted devices that are only USB controllers, the script works with number (Script generated by Onyx.) It will remove the USB controllers if the virtual machine is powered power

Now, if I repeat this process and the virtual machine has some unwanted devices which include the USB controllers. Now I also include floppy, series and parallel, then the script error when I change to delete based on a list of "equipment" unwanted devices In this case, whether or not I jump on all the unwanted material that isn't USB. The error comes from the vCenter events, no powershell & task. I even used onyx to compare to remove the USB from the GUI and it has always had the same result.

Now it's the slightly modified version that I could use to achieve what I want, if it is not error on:

$NotWantedHardware = "USB|Parallel|Serial|Floppy"
$ConfigureVM=$true
$VMs = Get-VM $args[0]
    
Write-Host "Unwanted VM hardware Report & Remove."
foreach ($vmx in $VMs){
    $vUnwantedHw = @()
    $vmxv = $vmx | Get-View
    $vmxv.Config.Hardware.Device | where {$_.DeviceInfo.Label -match $NotWantedHardware} |  %{
        $myObj = "" | select Hardware, Key, RemoveDev
        $myObj.Hardware = $_.DeviceInfo.Label
        $myObj.Key = $_.Key
        if ($vmx.powerstate -notmatch "PoweredOn" -or $_.DeviceInfo.Label -match "USB"){$MyObj.RemoveDev = $true}
        else {$MyObj.RemoveDev = $false}
        $vUnwantedHw += $myObj | Sort Hardware
    }
    Write-Host "Here is $($VMX)'s unwanted hardware"
    $vUnwantedHw | Select Hardware, @{N="Can be Removed";E="RemoveDev"} | ft -AutoSize #Output for display        
    if($ConfigureVM){# Unwanted Hardware is configured for removal
        $i=0        
        $vmConfigSpec = New-Object VMware.Vim.VirtualMachineConfigSpec
        foreach($dev in $vUnwantedHw){
            if($dev.RemoveDev -eq $true){
                $vmConfigSpec.DeviceChange += New-Object VMware.Vim.VirtualDeviceConfigSpec
                $vmConfigSpec.DeviceChange[$i].device = New-Object VMware.Vim.VirtualDevice
                $vmConfigSpec.DeviceChange[$i].device.key = $dev.Key
                $vmConfigSpec.DeviceChange[$i].operation = "remove"
                $i++
                $vmxv.ReconfigVM_Task($vmConfigSpec) #!#New Location, attempting to bypass error
                Write-Host "Removed $($dev.Hardware)"
            }
        }
#   $vmxv.ReconfigVM_Task($vmConfigSpec) #!#Old location, attempting to bypass error
    }# Unwanted Hardware is configured for removal
}

All are facing this problem, or should I just remove everything while his power, all in script?

I know the SDK Reference said you only need the Key property, but from experience I learned that it is apparently better pass the complete VirtualDevice object.

Try it like this

$NotWantedHardware = "USB|Parallel|Serial|Floppy" $ConfigureVM = $true $VMs = Get-VM $args[0]

Write-Host "Unwanted VM hardware Report & Remove." foreach ($vmx in $VMs){
  $vUnwantedHw = @()
  $vmxv = $vmx | Get-View  $vmxv.Config.Hardware.Device | where {$_.DeviceInfo.Label -match $NotWantedHardware} | %{
    $myObj = "" | select Hardware, Key, RemoveDev, Dev    $myObj.Hardware = $_.DeviceInfo.Label    $myObj.Key = $_.Key    $myObj.Dev = $_    if ($vmx.powerstate -notmatch "PoweredOn" -or $_.DeviceInfo.Label -match "USB"){$MyObj.RemoveDev = $true}
    else {$MyObj.RemoveDev = $false}
    $vUnwantedHw += $myObj | Sort Hardware  }
  Write-Host "Here is $($VMX)'s unwanted hardware"  $vUnwantedHw | Select Hardware, @{N="Can be Removed";E="RemoveDev"} | ft -AutoSize #Output for display
  if($ConfigureVM){# Unwanted Hardware is configured for removal
    $vmConfigSpec = New-Object VMware.Vim.VirtualMachineConfigSpec    foreach($dev in $vUnwantedHw){
      if($dev.RemoveDev -eq $true){
        $vmConfigSpec.DeviceChange += New-Object VMware.Vim.VirtualDeviceConfigSpec        $vmConfigSpec.DeviceChange[-1].device = $dev.Dev        $vmConfigSpec.DeviceChange[-1].operation = "remove"        Write-Host "Removed $($dev.Hardware)"      }
    }
    $vmxv.ReconfigVM_Task($vmConfigSpec)
  }# Unwanted Hardware is configured for removal
}

Note that the index of-1 returns the last entry in a table in PowerShell, avoids having to make this variable $i :-)

    How can I remove my photos from my iPhone while keeping in iCloud? because I'm running out of space on my iPhone.

    I want to keep all my photos in iCloud. I want to remove some of them from my iPhone 4 (IOS 8) in order to free up space on my iPhone. How can I do this? Thanks for help.

    With iCloud library enabled, you cannot delete a photo on a device (or iCloud.com) without deleting each device which uses iCloud photo library (iCloud.com). In order to save space on your mobile devices (and indeed your Mac if you want to) turn on the optimization of the pictures on these devices (settings > photos & camera > optimize storage on your mobile device and Photo preferences > optimize storage on your Mac)

    Dynamic optimization, it reduces the resolution of your photos, if necessary, so that you don't notice it occurring initially. However, when necessary, it is very effective, and users have reported libraries being optimized for much less than 10% of their original size in some cases. My own library is about 9% of its original on my phone size.

  • Can I remove this data store?

    Hello guys,.

    I free up space in a storage, and for that to work correctly, I followed the following steps:

    1. I created a new data store in other containers for storage.

    2 - I did a migration of storage of the old data store to the new.

    3 - remove the old VMDATA.

    At this point, I glued, because the old data store is not empty... West a strange folder inside, but I don't know if I can remove it, as you can see in the image below.

    files and folder in dotted lines are normally for the metadata of the data store itself.

    so, you can delete the data without any problem store.

    BTW. If you delete a data store and it is still used by a virtual machine the delet-job will be cancelled. There is a small security bit set

  • How to remove a data store abandoned?

    Hello! I am the systems administrator for my organization where we have HP P6300 storage attached to our cluster of ESXi5. Usually, if we need a new Vdisk to any virtual computer, we create a new vdisk in storage and add them as a new data store in Vsphere, then we create the file within this new data store vmdk. I had to remove a disk of a virtual server. The steps are as below:

    1 remove the data from the drive

    2. remove the disk from the virtual machine and delete the vmdk file

    3 remove the data from the cluster of data store store

    4. remove the data store

    5 remove the vCenter store data (inventory------Clusters data store and data warehouses-right click on the data store and delete)

    6 - anyone the vdisk to ESXi hosts

    7 remove the vdisk to Storage Manager.

    But I made a mistake and missed the STEP n ° 4 and 5.

    Now I see the attached message whenever I'm trying to remove it. Guidelines for this problem and remove this missing data store in the vCenter?

  • Remove a data store

    I need to remove a data store so that I can reformat vmfs3 to vmfs5. It is my understanding that vcenter will not introduce any APD or correct payday loans? The LUN will remain visible to all guests, as I said I just need to remove the data store on this subject, so I can recreate it with vmfs5.

    I guess after I remove it, I should questions some hosts renumerisations (except done automatically vcenter) before I recreate?

    Thank you.

    You are right, since you don't anyone the LUN, there is no problem with ODA...

    Simply remove the data store and create a new one. After that you can rescan all hosts so that they detect the new format.

  • Could not start the new virtual machine or VM remove a data store

    Hi guys,.

    I'm not new with ESXi, but my knowledge with vCenter and Clustering must be improved, so here's my problem.

    We have a Cluster of 2 ESXi 4.1 hosts on a San with 2 VMFS.

    My first problem is when I created a new virtual machine and try to start it, I got an error message similar to the one included with this post.

    My Second problem is more picky. Since I am unable to start my new virtual machine, I had removed from drive and I had created a new. But when I took a peek in the data store where was deleted VM, the directory with all the files are still there. When I try to delete it, I got an error message telling me that it is impossible to proceed.

    Q please?

    Best regards

    82% of failure can be other issues.  The article below

    http://KB.VMware.com/kb/1006052

    Also, I saw, where bad records DB for your ESXi hosts can cause weird problems as well.  The host with the problematic guest, can you do a right click on it and "disconnect"?  Try to get out of the bunch at the data center level.  If you get an error vCenter, that means return folder DB.  From there, while the host is in a disconnected state, remove the host to vCenter, then "add host". This will update the DB record.  Maybe worth it?

  • Cannot remove the data store in esxi 3.5 - can help you

    OK - I have a problem. I messed up and now I'm stuck.

    I was "apparently" in the middle of a converter working, and I deleted the comments of esxi3.5, while the converter still worked.

    I selected the rafale and made a removal of the disc that worked, however the structure of associated file (windows 2000 Server) for this guest has not been deleted, so I chose my data store (datastore1) and - do you have a store of navigation data and when I try to delete the folder associated with the guest, I deleted I get the following error :

    "General failure caused by file" (with a "/" on the next line) and all I can do at this point is to click OK box to acknowledge the error and I can't delete the folder. I can't rename it either.

    I don't know how to get rid of it. I tried to create a new client with the same name as the folder and delete the comments again, but that does not work either.

    I'm really stuck - I'm afraid to go into maintenance mode because I have no idea what I'm going to be confronted here since I never used the maintenance mode.

    any help or ideas would be really appreciated.

    You can try to do a refresh of the data store. The folder structure is not re read very often. In the data store Navigator, click the folder root on the left side and click on the Refresh button.

  • C670-105 satellite unwanted reboot while playing a game

    Hello

    I had the same problem in the previous months, when I'm playing Football Manager 2011 on my Toshiba laptop.

    The game requires a lot of CPU at some point (when I move forward step, CPU and game create other teams results and create new next and so on) and it breaks after 1-2 hours of play.

    It gets stronger and stronger and that's it!
    PC automathically restart and I lost my time!

    It could be overheating CPU, but I get this problems only by playing this game.
    I can't forget to play while listening to the music from Youtube or any other source or Skype chat in the background, it remains only for a few minutes then it will restart the PC again and again.

    Who is wrong? Overheating or something else?
    Maybe I just need to reinstall any Windows or game (FM 2011)?

    I use: Toshiba C670-105 / Cor Intel i3 2.53 GHz, 4 GB RAM, Win 7 Home Premium 64-bit SP1, 300 GB drive HARD, DirectX10, NVIDIA GeForce 315 M

    My backup is currently approximately 180 MB. And of course, my laptop is above the minimum requirements to play this game.

    Any tips?

    > Whats wrong? Overheating or something else?
    Well, I think that nobody would be able to say exactly why the device stops without any further investigation.
    Usually the laptop could power OFF due to high temperature and high temperature is mainly the reason of downs stop unwanted automatic.

    Never clean the laptop s cooling fans in the past?
    No.? Probably dust and debris inside the cooling modules prevent the fans to run with the best performance and cause high temperatures, leading to the closing down.

    I recommend you to use a jet of compressed air to get rid of the dust. But sometimes these cooling modules should be cleaned professionally.
    But try first of the jet of compressed air.

    You have disk problems as the CD/DVD is actually 4 discs in 1 case (CD & DVD burning and)

    Try this - Panel - Device Manager - CD/DVD - double click on the device - driver tab.

  • Safely remove a data store

    The procedure will be the same for 4.x, then Yes, there will be some host commands involved. It seems really involved, but it really isn't so bad. Much better than potential wickedness that could come to remove them is not the right way.
