I've just published a powershell module on GitHub that is using the WSAPI for querying informations about the array.
For now it's not possible to configure the 3PAR, maybe in a next release !
GitHub page: https://github.com/equelin/3PAR-Powershell
This is a side project so don't expect to have a professionnal software but I'm sure it can be quiet useful.
I would appreciate if you could provide me any feedback
