Hi Peter, Does this command even do anything? I'm not an HSM guru but PERCENTVALID(0) says only process if the tape is empty. Doesn't HSM automatically recycle empty tapes? If you want to recycle tapes that are getting close to empty you need to increase the 0. I would try running it with 5 or 10 with the DISPLAY on to see what quantity of tapes will get recycled if you actually execute it.
You have DISPLAY - which I believe tells HSM to only report eligible tapes, but not do anything with them. I believe you would need to change that to EXECUTE to have HSM actually do anything with the tapes. We have our HSM recycling tapes at 30%. This is a holdover from when we had a physical library with a limited number of tapes in it. We could probably lower that number since our VTS is using virtual 3490s instead of high capacity TS11xx tapes so burning a few virtual tapes to lower the churn would probably be OK.

Right now I do with zero but is it ok to do with with little higher percentage 5 ?
