CKM02426W BCS Backup(s) may be unavailable to RECOVER BCS.

Explanation

BACKUP BCS has detected that all copies of the backup dataset created via the OUTFILE or OUTDATASET keywords are SMS-Managed and cataloged in the same usercatalog that is currently being backed up. Should this usercatalog become damaged or inaccessible, none of these backups will be available to recover this usercatalog.

z/OS operating systems no longer support the use of VOL=SER= in JCL to access SMS-Managed datasets that are not cataloged.

User response

For the production environment, it is recommended to create dual backups that are cataloged in different usercatalogs. Otherwise, cataloging an SMS-Managed backup dataset in the very usercatalog that is being backed up is paradoxical for BCS recovery.
