Just a quick one liner I used to gather a list of VMWare Hosts including their cluster and datacenter.
get-vmhost | Select Name, @{N=”Cluster”;E={Get-Cluster -VMHost $_}},@{N=”Datacenter”;E={Get-Datacenter -VMHost $_}} | Export-csv c:\temp\inventory.csv
Here is a quick one liner I found to check for any VMs which had memory limits set on them:
Get-VM | Get-VMResourceConfiguration | where {$_.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.
