Is it possible to copy LDS dataset using IDCAMS REPRO? (manual is clear
- yes)
I mean CI level operations, since there are no records inside.
Control Intervals are "EF-agnostic", so the source can be non-EF and
target can be EF.
So, wouldn't be possible dss would use IDCAMS under the cover?

Ok, yes.
Then that is correct and the way I things should be working. My friend is the
REDBOOK VSAM Demystified…it has a nice section for each of the two Extended
Addressable VS Extended Format.
So, Extended Addressable is typically required to be Extended Format (and
therefore SMS), except for non-SMS LDS (apparently) which can be Extended
Addressable and non-SMS.
So, the 32-byte larger physical block size for extended format data sets still
holds true on why we cannot copy between them.
Thanks,

Let me rephrase that. The LISTC command on the non-SMS managed VSAM LDS has an
attribute of EXT-ADDR, whereas the SMS managed VSAM LDS has both EXT-ADDR and
EXTENDED. I had assumed that EXT-ADDR requires EXTENDED. I'm a tad confused.

Hi Mark, as far as I know SMS is a requirement for extended-format data sets.
If you were able to create a non-SMS extended format, it would indeed be news
to me.
Can you show me how you created them and the catalog entries that reflect that
EA/EF status.
Thanks!

I can define an EA/EF VSAM Linear dataset on both SMS and Non-SMS volumes. Both
are usable and the catalog entries for both reflect their EA/EF status.

Hi Mark,
The reason ADRDSSU cannot copy/restore non-SMS extended addressable VSAM LDS
data sets to SMS managed extended addressable VSAM LDS is because the non-SMS
EA is not an extended-format data set, which requires it to be SMS. The SMS EA
is extended-format, and therefore it has an additional 32bytes per physical
block. Since the blocks are not the same, we cannot copy/restore tracks between
them.
I hope this answers your question,
Thanks!

I got around the problem a different way, but I'd really like to understand why
ADRDSSU won't restore(logically dumped) or copy a non-SMS extended addressable
VSAM LDS dataset to an SMS managed extended addressable VSAM LDS. Is there
something within the physical dataset that's different between it being SMS
managed vs not being SMS managed?
