Do all of the hosts have VMs that are thin provisioned?
In general, the Storage Manager reporter tries to show options that are available in the data of the report.
According to the person wanting to run the reports - yes those hosts do have VMs that are thin provisioned.
I did notice that when I drill down into one of the ESX devices that is not showing in the report that the "Thin Provisioning" screen under "STORAGE" tab is blank. Does somethingneed to be enabled that ESX host or the provider that allows the Thin Provision data to be collected?
Or maybe the data stores aren't Thin Provisioned and it is working as it should....
