Determine whether you will use TAPEDSN in RACF® or TAPEAUTHDSN=YES in DEVSUPxx and define the DATASET profiles (refer to Using RACF DATASET class profiles). DFSMShsm maintains volumes in the TAPEVOL sets for HSM and ABARS tapes until you inactivate the TAPEVOL class.

RACF DATASET Class profiles should be used with TAPESECURITY(EXPIRATION, EXPIRATIONINCLUDE or PASSWORD). After changing the TAPESECURITY parameter, any new scratch tapes will be protected using expiration dates or password. Either of these protection cases may require tape initialization before reuse by the global scratch pool. Leaving TAPEVOL class active and HSMHSM, HSMABR and DFHSMx profiles defined ensures that tapes in DFSMShsm’s current inventory remain protected by RACF TAPEVOL until returned to scratch. When there are no volumes defined to the TAPEVOL profiles, you can delete the HSMHSM, HSMABR, and DFHSMx tape profiles. If you implement RACF DATASET Class Profiles and deactivate the TAPEVOL class, DFSMShsm will issue an error message when returning tapes protected by RACF TAPEVOL to scratch.
