Presumably also past DS1LSTAR?
I didn't want to write a novel. When I make permanent backups
with DSS, I normally use ALLEXCP; that way a clobbered LSTAR
doesn't prevent recovery of data.
I've never had the joy of setting up HSM, nor copying empty PDSs
with DSS, so can't attest to early performance. But I would find
it surprising if they failed. In my experience, stupid mistakes
aside, IBM tends to produce slow, but thorough utility code
(with modern SORT the exception, perhaps due to market pressure,
and the outstanding quality of the support team).
