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, -----Original Message----- From: IBM Mainframe Discussion List [mailto:IBM-MAIN@LISTSERV.UA.EDU] On Behalf Of Hervey Martinez Sent: Tuesday, October 10, 2017 1:16 PM To: IBM-MAIN@LISTSERV.UA.EDU Subject: Question about management class autobackup=y 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. ---------------------------------------------------------------------- For IBM-MAIN subscribe / signoff / archive access instructions, send email to lists...@listserv.ua.edu with the message: INFO IBM-MAIN ::DISCLAIMER:: ---------------------------------------------------------------------------------------------------------------------------------------------------- The contents of this e-mail and any attachment(s) are confidential and intended for the named recipient(s) only.
