drives - question:
If your jobs all used UNIT=3480, you're going to end up doing
search-and-replace on JCL because those aren't esoterics in your eligible
device table (EDT). It they were using UNIT=TAPE or UNIT=CART, the value
in the catalog (I believe, one of you with more expertise can correct me
if I'm wrong) reflects the esoteric and not the actual device.
The DEVTYPE in the catalog is the actual value not the esoteric. The
only time there is an esoteric is if the catalog entry is created via
a Catalog Command (ie: IDCAMS/IEHPROGM/etc or a JCL DISP=CATLG in an
IEFBR14 Step). I have the impression that for years if you open a
dataset via such an esoteric DEVTYPE entry, than at close time the
close code will automatically update the entry with the correct
devtype.
