Here is a quick one liner I found to check for any VMs which had memory limits set on them:

Get-VM | Get-VMResourceConfiguration | where {$_.MemlimitMB -ne -1}

If you want to target a specific cluster, just add Get-Cluster “clustername” to the beginning:

Get-Cluster “Clustername” | Get-VM | Get-VMResourceConfiguration | where {$_.MemlimitMB -ne -1}

Now if you want to get rid of the memory limits, add the following:

Set-VMResourceConfiguration -MemlimitMB $null

Final script for all VMs to find and remove limits:

Get-VM | Get-VMResourceConfiguration | where {$_.MemlimitMB -ne -1} | Set-VMResourceConfiguration -MemlimitMB $null

Next step…setting this as a scheduled workflow in Orchestrator to run every night/week and send a report out of any limits discovered.
