DFSMShsm/ABARS Considerations

DFSMShsm calls the ARCTVEXT exit for tapes no longer needed by ABARS. Because ABAR tapes may not be controlled as EDM tapes, the following message may be issued:

TMSTMSTV-08 vvvvvv EXPIRE IGNORED, NOT EXTERNALLY MANAGED

To prevent this problem, we recommend that you control ABAR tapes with EDM.

Note: For more information about changing the EDM rules, see the Programming Guide.

You can use a new EDM name or an existing EDM name, and any combination of data set name and program name to identify the ABARS tapes.

To identify ABARS tapes as EDM controlled tapes

1. Use either TMSGRW or CA Earl to create a list of the volumes you want treated as EDM controlled tapes.
2. If secondary files are present, use the TMSAGGR utility to purge all DSNB records (secondary file records) for those volumes. If secondary volumes are present, use TMSUPDTE to zero out the NEXTVOL, PREVVOL, and 1STVOL fields and set the VOLSEQ to 1.

   The tapes are all single-data set, single-volume entities.

3. Use the TMSUPDTE utility to turn on the X'20' bit in FLAG3 ('controlled by external manager' indicator) and to set the EDM field to the name you chose.

   The ABARS tapes are identified as EDM controlled.
