Issue/Introduction

Why do we get ARC0050A and ARC0055A error msges when we do not use DFSMSHSM?

Environment

Release: SMDI3900200-12.5-Disk-Backup and Restore-for z/OS
Component:

Resolution

Even though HSM is not used to archive or restore datasets, the HSM software can
build a CVTHSM control block entry which the RACF software will look at to determine
if HSM is active or not and then trigger a call to HSM to recall a migrated/archived
dataset. RACF support has determined that this is a defect within RACF and will publish
an Apar and PTF fix.

Additional Information

The error messages are:
 
ARC0050A DFSMSHSM IS NOT ACTIVE - START DFSMSHSM
ARC0052A JOB xxxxxxxx WAITING ON DFSMSHSM
ARC0055A REPLY 'GO' OR 'CANCEL'
 
It was found that many (if not all) HSM commands issued on a system will
generate a CVT HSM control block entry even if DFSMSHSM is not active
and not licensed on the system.
  
A PMR was opened with IBM RACF level 2 who provided an Apar for this user.
