There is no work coming from the subsystem to classify in WLM. It's prevalent in any shop that has used "STK" SILOs or newer libraries like the SL8500. That's a lot of shops in my experience, but is less now than it was say 15 years ago from what I can tell. In looking at a manual, I see there are 8 subtypes related to the HSC component (robotics) and the virtual tape component - VTCS - and ExPR (reporting / performance tool) can generate subtypes 10-29 (with some of the ones in that range not used).
