True.
However I would prefer to have some feature to avoid creation of
invalid datasets.
I saw a lot of invalid datasets and none of them was really need by
the creator.
R.S.
Define invalid datasets, please.
From HSM's perspective, they lack a DSORG. Most frequently created
by JCL where the program doesn't actually OPEN the output file for
some reason.
On non-SMS disk, they can also lack an EOF mark with older z/OS (or
perhaps OS390)
From the comment it could have been a dataset that didn't have a
local standard name.
I had a standard (DASD) that if it didn't have a valid dsorg it was
deleted. I regularly went through and deleted them.
