PowerCLI - Get-DatastoreMountInfo (advanced function) and other commands

How to list datastore mounts, unregister VM's, unmount datastores, disable HA/DRS from a cluster (warning: disabling DRS deletes any resource pools from the cluster), and edit firewall rules.

Requirements for datastore functions: PowerCLI 5.0.1, Powershell v2 and the advanced function from:

The above failed because VM's existed on NTNX_datastore_1 on host 192.168.10.1. To resolve, unregister the VM's with the Remove-VM cmdlet (the -DeletePermanently flag would have deleted from disk):

Get-VM ubuntu-vmfs-0 | Remove-VM -Confirm:$false
Get-VM ubuntu-vmfs-1 | Remove-VM -Confirm:$false
