Roger, The TS7700 doesn't care what you write on the tape, but the system tends to want them all to be standard label. However, I do recall that we made specific support in DFSMSrmm to support both non-specific NL and specific NL processing in all system managed tapes. However, you do need the correct authorization through rmm to be able to change an SL tape to NL (facility class profiles specific to rmm)
rmm uses the volser provided by the TS7700 via OAM to track what you are doing and does whatever is necessary to allow the change to NL and, probably unfortunately, I suspect it will insist on relabelling back to SL on return to scratch ..... If you dont use rmm, you need to ask your vendor..... If you use rmm, just try it by coding LABEL=NL in your JCL. and see what EDGxxxxI messages are issued Mike Wood ---------------------------------------------------------------------- For IBM-MAIN subscribe / signoff / archive access instructions, send email to [email protected] with the message: INFO IBM-MAIN
