Description:
I would like to reuse an old range of VOLSERs for new media so that I don't have to extend the TMC. Are there any specific updates that should be done before reusing the existing VOLSER range?
Solution:
Before reusing the VOLSER range, they should all be in SCRATCH status with their DSN and DSN17 fields set to HEXZEROS. This update can be done via TMSUPDTE with the following control statements.
VOL=uuuuuu-vvvvvv,NODSN,NOCHAIN,SCRATCH REP DSN=HEXZEROS REP DSN17=HEXZEROS
If the new media is in an MTL (manual tape library) or is an EMC DLM device, then you should also set the DEN and TRTCH fields to the appropriate values to match the device definitions (i.e. 3480, 3490, 3590 etc.). The values for the DEN and TRTCH are listed in the Programmers Guide, appendix A.
To update the DEN and TRTCH fields with the HEX values from the appendix, you would add the following command to your TMSUPDTE control statements:
REP DEN=E8,TRTCH=E8 <<< These are the values for a 3590, 128 track tape from the appendix.
