HSM Duplex tapes
HSM duplxing requires that both the Primary and Alternate tapes be the same length (or the alternate needs to be longer). Is there any chance that requirement will change so that a 9840D could be the Primary while duplexing to 9840Cs, a shorter tape? Just a rumor heard at work that I would like to confirm or deny.

The names of our original files are DFHSM.HMIGTAPE.DATASET and DFHSM.BACKTAPE.DATASET. Tape name is irrelevant. HSM use non-specific volume request (mount scratch request). HSM inserts additional qualifier in dataset name, COPY to distinguish it from original. So it is up to you to direct original to local and copy to remote library. If you're using IBM ATLs then you can use ACS routines for that. Hint: assign different STORAGE CLASS, the rest should be indentical for both copies.

Re: Name of HSM duplex tapes?
From z/OS V1R6.0 DFSMShsm Storage Administration Guide, section on Names of Migrated Data Sets, 2.1.21.4.17: The following tape data set name for each copy of a cartridge-type tape volume is created by the TAPECOPY command or the duplex tape option: prefix.COPY.HMIGTAPE.DATASET and similarly in section on Generating Names of Backup Versions of Data Sets, 3.1.7.4.7: The tape data set name for each copy of a cartridge-type tape volume created by the TAPECOPY command or the duplex tape option is: bprefix.COPY.BACKTAPE.DATASET It would appear your prefix value is DFHSM.
