    Hi,

    As the Title suggests, this is messy.

    What we would like use workflow for is:

    - take multiple snapshots in vCenter

    - make the workflow take parameters

    - import the module VMware.VumAutomation

    Considering all the rules and restrictions regarding workflows I wonder if this is even possible.

    (not taking snapshots in the example, just testing with Get-VM)

              

    workflow VMSnapshot{
    Param(
      [array]$servers
    )
        inlinescript
        {
            Import-Module VMware.VumAutomation
            $vCenter = "XXXXXXX.YYY.intra"
            Connect-VIServer -server $vCenter

            ForEach -Parallel ($item in $servers)  
            {  
                   Get-VM -Name $item | select name,memorygb
             }

        }
    }


    } 

    VMSnapshot -servers "server1","server2"

    ----------------

    That's the code.

    Now I know that you can't use -parallel inside inlinescript. This is just the "pseudo-code" explaining the functionality.

    How would one go about to make this work?

    Thanks

    /Daniel

    Has to be done in this order:

    workflow VMSnapshot{
    Param(
        [array]$servers
    )
    ForEach -Parallel ($item in $servers){
        inlinescript{
            Import-Module VMware.VumAutomation
            Connect-VIServer -server "XXXXXXX.YYY.intra"
            Get-VM -Name $using:item
        }
    }
}


VMSnapshot $servers | select name,memorygb
    Of course a workflow is unnecessary unless you have hundreds of VMs.
