I found this post lurking my drafts area, I probably should have renamed it newish commands now but the information is still relevant.
3PAR OS 3.2.1 MU2 saw the introduction of VVOLs support for 3PAR, this meant a number of additional commands were also added to the CLI:
setvasa – Set the VASA Provider server properties.
startvasa – Start the VASA Provider server to service HTTPS requests.
stopvasa – Stop the VASA Provider server from servicing HTTPS requests.
showvasa – Show properties of the VASA web service provider.
showvvolvm – Show information about virtual machines (VVol-based) in the system.
