These are the SAF calls that DFSMSrmm issues to maintain the security protection of tape resources in your installation. They are not used to perform authorization checking. Authorization checking for access to tape data and tape volumes is still the responsibility of the OPEN macro and RACF. All these requests are issued from the DFSMSrmm started procedure address space.

When the requests are issued, the RACF ACEE control block for the DFSMSrmm started procedure has the privileged bit on (ACEEPRIV), so that DFSMSrmm requests are honored without authorization checking being performed.

Calls for TAPEVOL class are only issued if RACF is active and the TAPEVOL class is active. Calls for DATASET class are only issued if RACF is active and the TAPEDSN option is active.

For additional information on SAF calls, refer to Table 1.
