Yes, the management class stipulates the number of days before the go to ML-1 and then ML-2. When the dataset has not been deleted HSM keeps 3 backups. When delete HSM keeps only 1 backup. It is the same for both situations I am observing.

I am conflicted by a behavior in our zOS 1.11 system. We have a Management Class defined to expire datasets after a given number of days. I know it is working because I found some datasets about to expire, waited for them to expire, and now I can see they are no longer in the catalog (the management class stipulates that we keep one backup for a few years after deleting). But, I also noticed that some files that have exactly the same management class and should have been expired/deleted a long time ago are still catalogued. I recalled one of them and it had no expiration date and confirmed that it belongs to the same management class. I am trying to figure out why this behavior is taking place but don't know where to go next. Any suggestions would be greatly appreciated.
