ERROR: New-Snapshot (Operation is not valid due to the current state of the object)

Hello guys!

I've been googlin around a bit, but cannot find a solution to my problem. Hopefully one of you skilled people can point me in the right direction:)

I've created a powerCLI script to take a snapshot of our most important servers before we do our weekly maintenance. The idea to run the script as a regular powershell script and then have it

  1. Add powercli snapins and connect to virtualcenter servers
  2. query the VC servers for VMs in a perticular folder
  3. Run a foreach loop on these servers to create a snapshot with name $snapshotname

Currently i'm just running it on a test folder that I created in vSphere that contains 3 test VMs:

  • Testmagne1 - Working normally
  • Testmagne2 - I've renamed the folder for this VM in the datastore in order to generate an error.
  • testmagne3 - Working normally

Since the servers (not the test servers, but the proper ones) are the most important servers in our environment I want to be able to catch exceptions and errors when i run this script. I do this with the Try - Catch - Finally functions.

The weird thing is this:

The output from Powershell/PowerCLI is different from the output in VirtualCenter(!)

In virtualcenter the output is as follows

  • Testmagne1 - Snapshot is created successfully - As expected
  • Testmagne2 - Snapshot creation fails as it cannot find the .vmx files - As expected
  • Testmagne3 - Snapshot is created successfully - As expected

However, the output from powercli is slightly different:

  • Testmagne1 - Snapshot is created successfully - As expected
  • Testmagne2 - Snapshot creating fails as it cannot find the .vmx files - As expected
  • Testmagne3 - Snapshot fails with the error message: Operation is not valid due to the current state of the object - Huh?


Apparently once the first error is generated all succeeding VMs get the error "Operation is not valid due to the current state of the object"


I've been pulling my hair out trying to figure this problem out, but I am not getting anywhere


Here's some additional information:

1. The Script (short version of it. It generates the same error):

--------------- START SCRIPT-----------------

$ErrorActionPreference = "Stop"

Add-PSSnapin VMware.VimAutomation.Vds, VMware.VimAutomation.Core | Out-Null

Connect-VIServer VIRTUALCENTER1, VIRTUALCENTER2 | Out-Null  # Sensored the VirtualCenter names

$servers = Get-VM -location "testfolder"

$snapshotname = "Testsnapshot"

$verifycreatesnapshot = Read-Host "You are about to create snapshots for $servers. Do you want to continue? y/n"

    if ($verifycreatesnapshot -eq "y"){

        Write-Host "Creating snapshots..."

       

        ForEach ($i in $servers) {

            Write-Host "Creating snapshot for $i"        

            Try {New-Snapshot -VM $i -Name $snapshotname | Out-Null}

            Catch{$_.exception | select * ; Write-Host "Failed to create snapshot for $i";} 

        }

        Write-Host "Command finished"

    }

    else{Write-Host "Operation cancelled by user"}

Read-Host "End of script. Press ENTER to close"

------------------ END SCRIPT -------------------

Thank you RonPSSC. After tearing my hair out over this for a few hours, I found your post, restarted my PowerShell session, and all is good.

Add me into the tearing my hair out group who stumbled across your solution. Didn't even think to terminate and re-open the PowerCLI session...but it worked!
