so for b you want to see what pvs are set on each device and how much of that device is not allocated ? you will probably need to write an extended object to show that and then snapshot that.
That's exactly what I want to see. I think I'll just create an NSH script to gather the data as we don't need it available real time and the results needn't clog up the BSA DB - all the data is being collated elsewhere.
Thanks for the prompt response.
