We have several files that are receiving RC=53 and the management class has autobackup=y. The help panel in ISMF, describes this field as, "Automatic backup is allowed" but since these files are erroring that means that "backup are required".

We don't run HSM backups since we rely on FDR for that.

just wondering as to why the discrepancy on this field and if anybody can offer an explanation.

HSM (by default) will not expire a dataset if HSM does own a backup copy. It does not communicate w/FDR, nor know anything about any backups FDR may/may not have.
This is the meaning of RC=53.

This behavior can be changed by a patch described in: SC23-6869-02 z/OS DFSMShsm Implementation and Customization Guide
pp360 "Disabling delete-if-backed-up (DBU) processing for SMS data sets"

The citation above is the z/OS 2.2 version. Check the Impl/Cust guide for your release as the offset may have changed.

HTH,

Replying to my own post. The below should read:

Ok and I've read some manuals and the description for this field is, "backups can be run" but does not mention about a backup required if this field is set to 'Y'. I guess my question is on the wording for this parm.


I've always interpreted as required if it was set to Yes but I was asked why the discrepancy and I did not know how to answer.

AUTOBACKUP=Y says backups will be taken by HSM.
However, what the description does not say, is that HSM Auto-backup needs to be configured.
This is handled by SETSYS AUTOBACKUPSTART and IIRC, SETSYS CYCLE.
CYCLE says which days to perform actions AUTOBACKUP start gives a window for starting the autobackup task
