If the dsn is not migrated because migration is broken for that dataset *and* 540 days go by, then YES, it will expire if it has not been referenced. For 540 days. It is not a matter of precedence.
An exception to all this is threshold mangement. If HSM doesn't think the volume meets criteria to qualify for PSM or SSM, then a dataset can sit on a primary volume forever. -----Original Message----- From: IBM Mainframe Discussion List [mailto:IBM-MAIN@LISTSERV.UA.EDU] On Behalf Of esmie moo Sent: Wednesday, October 29, 2014 8:24 AM To: IBM-MAIN@LISTSERV.UA.EDU Subject: Re: DFHSM QUESTION - EXPIRATION OF DSN Bob, I understand that.

After 4 days of non-usage, the dsn *will* migrate to ML1. After 7 more days of non-usage, it will migrate to ML2. After 540 days, it will expire. If the dataset has not migrated, numerous possible conditions exist: 1) it was referenced and therefore not eligible for migration because of usage. 2) it has not been backed up and is not eligible for migration 3) the volume is not eligible for migration and/or backup 4) something else is afoot that we are not aware of (premature ending of space management windows, etc.) Bob -----Original Message----- From: IBM Mainframe Discussion List [mailto:IBM-MAIN@LISTSERV.UA.EDU] On Behalf Of esmie moo Sent: Wednesday, October 29, 2014 7:32 AM To: IBM-MAIN@LISTSERV.UA.EDU Subject: DFHSM QUESTION - EXPIRATION OF DSN Good Morning Gentle Readers, I have a question about the expiration of a dsn by HSM. The rule says the following : Expiration Attributes Expire after Days Non-usage . : 540 Expire after Date/Days . . . . : NOLIMIT Retention Limit . . . . . . . : 0 However the Migration attributes are as follows: Migration Attributes Primary Days Non-usage . : 4 Level 1 Days Date/Days . : 7 Command or Auto Migrate . : BOTH My question is will HSM delete the dsn if it is NOT migrated? I think that the DSN needs to be migrated in order for HSM to delte the dsn. Could anybody confirm my comprehension or mis-comprehension should it be the case? Thanks. ---------------------------------------------------------------------- For IBM-MAIN subscribe / signoff / archive access instructions, send email to lists...@listserv.ua.edu with the message: INFO IBM-MAIN ---------------------------------------------------------------------- For IBM-MAIN subscribe / signoff / archive access instructions, send email to lists...@listserv.ua.edu with the message: INFO IBM-MAIN ---------------------------------------------------------------------- For IBM-MAIN subscribe / signoff / archive access instructions, send email to lists...@listserv.ua.edu with the message: INFO IBM-MAIN
