The manuals are indeed not clear what the LRECL and BLKSIZE should be as target for EXPORTing those HSM VSAM datasets. (.... unless I missed them somewhere, but the samples shown are for general KSDS VSAM datasets and some samples are for tapes) I'm not sure if EXPORT is the right one, but you can use that. That is if HSM is not updating these VSAM datasets while you are EXPORTing them. But, I would allocate a new set of MCDS, BCDS and OCDS with new names and same attributes. Then I would bring HSM down everywhere, do a IDCAMS REPRO. After that just IDCAMS ALTER on both sets so when HSM is running up again, it will use the new set and you have a backup MCDS, BCDS and OCDS. Above is a tedious PITA of course, but I prefer proper backups with nothing which could change those VSAM datasets. I agree, I don't have really an answer for attributes of EXPORT targets, because I never used EXPORT for those specific HSM datasets. I have used that EXPORT for other things like catalogs for example. Good luck!
