Dave, I know DFHSM won't migrate a dataset without it being backed up beforehand, but it won't delete one either? The manual I'm looking at says that DFHSM processes expiration attributes before it processes migration attributes. And in the backup section of the same manual it says the number of backup copies of a deleted dataset says how many to retain. It says nothing about needing to have backups before allowing a delete.
I double-checked and the datasets I'm testing with have all their attributes. I guess I'll wait a week and see if the one I updated will go away. Thanks.

But, it won't mess with invalid datasets. An unopened dataset could be incompletely defined (usually an unknown DSORG). And, usually DFHSM won't migrate or delete without a backup existing.
