Updating the PSAutolab Module

This document was written to support updating from older versions of this module to version 4.x. It is being retained for archive and information purposes. If you are updating from version 4.x to a later version, please refer to the latest update documentation.

This module and its dependencies will be installed and updated from the PowerShell Gallery. It is strongly recommended that you do not upgrade the module if you have configured labs and virtual machines. If AutoLab is in use now, you can wait until you are finished with the lab configuration. Otherwise, use the Wipe-Lab command in any configuration folder that has MOF files with virtual machines.

Note: The terms AutoLab and PSAutolab are used interchangeably. PSAutolab is technically the PowerShell module that manages your AutoLab configuration.

You should be able to run

Update-Module PSAutolab

Updating Troubleshooting

However, there is the potential for issues with required Lability module. You can always try this:

Update-Module Lability
Update-Module PSAutolab

In certain situations, the Lability module may encounter a security validation bug between versions. You can try this sequence of commands.

Install-Module Lability -SkipPublisherCheck -force
Update-Module PSAutolab

If you still have issues, the best course of action is to uninstall the modules and re-install.

Get-Module PSAutolab -ListAvailable | Uninstall-Module
Get-Module lability -ListAvailable | Uninstall-Module

You might need to repeat this process until this command shows no modules.

Get-Module lability,PSAutolab -ListAvailable

With a clean slate run:

Install-Module PSAutolab -SkipPublisherCheck -Force

You do not need to run Setup-Host. But you should run Refresh-Host to copy updated lab configurations to your Autolab setup.

Disk Image Update

If you have been using PSAutolab for awhile, are updating it and plan to continue using it, you might want to refresh the virtual disk images. An update to the PSAutolab module might also include a reference to a new version of the Lability module. This module is responsible for downloading the latest ISO images and creating the master virtual hard disks.

You should only refresh disk images if you have no configured virtual machines.

Get-ChildItem C:\autolab\VMVirtualHardDisks

If this directory is empty, then you can proceed.

Get-ChildItem D:\Autolab\MasterVirtualHardDisks\ | Remove-Item

The next time you build a lab, the master disk image will be recreated.

ISO Management

Likewise, you might want to refresh the ISO images found in C:\Autolab\ISOs. You can delete any or all ISO images. The latest version of a required ISO will be downloaded the next time you build a lab.
