This came up whilst doing preparation and writing for a forthcoming exam prep book. There was an objective that required changing the location of a VM Swap file. There are two PowerCLI one-liners that can help you here. One for the cluster level, then one for the hosts.
PowerCLI – Change the VM Swapfile location at the Cluster level
Get-Cluster -name “Dragons Nest” | Set-Cluster -VMSwapfilePolicy InHostDatastore
PowerCLI – Change the VM Swapfile location at the host level
Get-Cluster -name “Dragons Nest” | Get-VMHost | Set-VMHost -VMSwapfileDatastore “*local*”
Keep in mind, these are both one-liners, so you may need to do some copy/pasta-fu on them (along with changing cluster names, etc).
