I Understand that this is still a very early release, and you're still working you're way through the OnTAPI, but we need some formatters make the toolkit usable as a CLI. I've used PoshOnTAP as my primary means of managing our filers for over two years now. I tried to switch to the supported toolkit, but the output is of no use from the CLI. It's simply information overload... because I've been through this once already with PoshOnTAP, I wrote an example for you...
As a template I've always used FilerView.... I know, I know... but *most* Windows sysadmins don't administer NTAP Full time, and FilerView is their interface (SystemManager is getting there). The closer you mimic FilerView's data the easier it is for them to translate the GUI to the CLI. Everything is still available for scripting, but if you trying to manage a volume, lun, snapshots, etc from the CLI it's much easier.
Attached is what I'll be using until you fix it
