The HSM manuals do not clearly state that the objective of HSM is to
re-create the dataset as it was previously created. For example, with the
right options a HSM recall can convert a SMS-managed data set to
non-SMS-managed and vice versa (with some restrictions, of course). I agree
that some changes like making the LRECL smaller or converting from/to EBCDIC
to/from ASCII would destory data. However, HSM could be designed to perform
useful minor format changes during a recall. I would love it, if HSM had
recall options to change the primary and secondary allocation quanities,
non-EA to EA, change blksize or cisize, etc.
Well, it depends on definition of "minor change". ExtFmt, CISZ, BLKSIZE
are NOT minor changes in my understanding because they change format of
*existing* data. There are aplications CISZ or BLKSIZE dependent, Ext
Fmt *is* physically different, etc.
SMS-managed or not does not affect the data itself.
