ARC6074E

Explanation
 RACF® is
installed in the computing system and is active. The system-wide RACF tape volume protection option
is in effect. DFSMShsm makes
an attempt to add the tape volume serial number of volser to
the ABARS tape volume set of HSMABR and fails.  If the return code is 24, DFSMShsm has intercepted a 585 abnormal
end (abend).
If the return code is 20, RACF has
failed the request or the issuance of the RACDEF SVC has resulted
in a nonzero return code.
If DFSMShsm has
intercepted an abend, ABEND is indicated instead of a reason code.

System action
 DFSMShsm processing continues.

Programmer response
 This message informs you of an error that
has occurred when DFSMShsm has
attempted to add a tape volume to the ABARS RACF tape volume set.  If the return code is 24, an ICH409I message will also be issued.
The RACF reason code is xx.
For a description of the RACF abend
and reason codes, see z/OS Security Server RACF Messages and Codes.
If the return code is 20 and an abend did not occur, the reason
code is one of the possible return codes from the RACDEF SVC in z/OS MVS Programming: Authorized Assembler Services Guide
