After a bit of googling I found the RefreshDatastore command - http://www.vmware.com/support/developer/vc-sdk/visdk25pubs/ReferenceGuide/vim.Datastore.html#refresh
However it seems I am not allowed to use it with ESXi free version.
Are there other commands which will allow me to get real up to date data on free space?
The reason I ask is that I need to generate reports and raise alarms if we are running low on free space on datastores. Problem is that the data is not accurate until I manually refresh the data in VSphere Client.
