In the case of multiple steps each allocating one file on the same
tape, and no AFF parameter used, there was (is?) a significant
difference between JES2 and JES3.

For allocating tape drives within a step (and UNIT=AFF is only within
a step) UNIT=AFF is still needed to allocate SORTIN and SORTOUT in
SORT operations to the same drive in both JES2 and JES3 (or for any
other non-concurrent allocations where it is possible to share the
drive.
IMHO it's bad idea to use tapes for such operations. Tapes nowadays are 
for backups, dumps, ML2, etc. but not direct application use.

We are still committed to deliver some products (or at least
their corrective service) to some customers on tape.


Oh, yes, software installation, I didn't mention it.
(Disclaimer: I'm fully aware that customer decides, so you have to 
follow his requirements.)


However ... what tape format do you deliver?
I'm pretty sure you don't deliver virtual tapes ;-)
3480 aka 18 trk aka CST?
3490E aka 36 trk aka ECCST?
Please note, nobody manufactures new media (although it is still 
possible to purchase already produced carts). It's even worse with the 
drives. New drives are unavailable for many years, service of existing 
ones is very limited.


So, what tape media to choose? Obsolete MAGSTAR family?
Or maybe Jaguar, but maybe someone decided to use STK tapes?

Note, the drive used just for software installation purposes is very 
expensive toy, it's definitely not a 3,5 FDD. The cost of single 
(first) Jaguar drive can be as $100k high.

A lot of money spent just to insist on tape media for the installation.
