Powershell / PowerCLI Script to List & Unmount ISO on VMWare VMs prior to VxRail 4.5 or 4.7 upgrade

Posted by

In the past I have spoken about needing to remove mounted ISOs from VMs prior to a VxRail upgrade. I have had many people DM me asking if I use a script or do it manually. First, it would only be possible in a small environment to manually remove mounted ISO files or in environments that only have a couple. For enterprise environments, I use a powercli script. I wanted to take a moment to list the strings I use and allowyou to put them into your own script.

If you would like assistance in the below or have general questions about Cloud solutions, VMware, and more, feel free to visit the following URL and I will be able to work directly with you:

I wanted to give credit to Tomas Kalabis who posted the strings:

How to get the VMs with mounted ISOs:
Get-VM | Get-CDDrive | select @{N=”VM”;E=”Parent”},IsoPath | where {$_.IsoPath -ne $null}

If you want to export it to a csv then:
Get-VM | Get-CDDrive | select @{N=”VM”;E=”Parent”},IsoPath | where {$_.IsoPath -ne $null} | Export-Csv -Path “E:\Temp\VMs_ISOs.csv” -NoTypeInformation -UseCulture

If you want to unmount the ISOs
Get-VM | Get-CDDrive | where {$_.IsoPath -ne $null} | Set-CDDrive -NoMedia -Confirm:$False

A couple moving parts that make it a little work. However, it is far less work than if you had to do it manually. As always, I hope y’all found this useful.
