Using Job Groups in VMM Scripts

The JobGroup parameter uses an identifier to group a series of commands into a single job group that will run as a set just before the final command that includes the same job group identifier runs.

The JobGroup parameter requires a GUID, which you must obtain before setting the value for the JobGroup. The following command demonstrates how to generate a globally unique identifier (GUID) and store it in the $JobGroupID variable:

$JobGroupID = [Guid]::NewGuid().ToString()  

To include subsequent commands in the job group, set the JobGroup parameter for that command to the same value. For example, all commands that include -JobGroup $JobGroupID will not run until just before the final command that also includes -JobGroup $JobGroupID.

The following example demonstrates how to use JobGroup in a script. The New-SCVirtualDiskDrive cmdlet in the third line queues the work to be done by New-SCVirtualDiskDrive, but does not run until just prior to the New-SCVirtualMachine cmdlet. New-SCVirtualMachine is the last command that includes JobGroup and initiates work, bundling in any previously queued work. In this case, that means running New-SCVirtualDiskDrive and then New-SCVirtualMachine.

# Generate a GUID for the JobGroupID variable.  
$JobGroupID = [Guid]::NewGuid().ToString()  
$VHD = Get-SCVirtualHardDisk -VMMServer "" | where {$_.Location -eq "\\\MSSCVMMLibrary\VHDs\Blank Disk - Large.vhd"}  
# This is the first cmdlet that uses the JobGroup variable.  
New-SCVirtualDiskDrive -IDE -Bus 0 -LUN 1 -JobGroup $JobGroupID -VirtualHardDisk $VHD  
$HWProfile = Get-SCHardwareProfile | where {$_.Name -match "NewHWProfile01"}  
$VMHost = Get-SCVMHost -ComputerName "VMHost03"  
# This is the last cmdlet that uses the JobGroup variable, which indicates that  
# New-SCVirtualDiskDrive should run just prior to the following command.  
New-SCVirtualMachine -Name "VM10" -Description "New Virtual Machine VM10" -JobGroup $JobGroupID -VMMServer "" -Owner "Contoso\Katarina" -VMHost $VMHost -Path "D:\VirtualMachinePath" -HardwareProfile $HWProfile -RunAsynchronously -StartAction NeverAutoTurnOnVM -StopAction SaveVM
