Hello George
It might be good to look into Hitachi Ops Center - Protector AKA HDID(Hitachi Data Instance Director). It covers all the topics mentioned and is really fast. It also shows you the raidcom commands used for the jobs. If you'd like a demo feel free to reach out to CoE(Center of Excellence). Or take a look on Halo Labs.

Whats nice about HDID, it has a REST APi you can exploit to trigger and minipulate complex dataflows to do various tasks. It also supports all data copy operations, including TC, HUR, GAD, SNAPS, WORM SNAPS ect. Example Below:
