John, According to Lizette's post it won't make a difference. Lizette please correct me if I misspoke: "....JES2 requires that the data map to the same TTR. So the proclib could be moved, but the tracks not over written. So the TTRs would still be valid for that proc. The minute the space is reused, is when JES2 will provide the I/O error.
So it is not use going back to the same volume, but to the exact same TTR placements." ________________________________ From: John Dawes <jhn_da...@yahoo.com.au> To: IBM-MAIN@LISTSERV.UA.EDU Sent: Friday, March 22, 2013 8:08:15 AM Subject: Re: DFHSM QUESTION - RECALLING DSN TO ITS ORIGINAL VOLUME - FUTHER QUESTION G'day, In further to Willie's post, what if the dsn was recalled to the proper or original volume, must the JES2 proc need to be refreshed because the dsn may not have been placed on the same track or cylinder? ________________________________ From: Walter Marguccio <walter_marguc...@yahoo.com> To: IBM-MAIN@LISTSERV.UA.EDU Sent: Thursday, 21 March 2013 4:54 PM Subject: Re: DFHSM QUESTION - RECALLING DSN TO ITS ORIGINAL VOLUME > From: willie bunter <williebun...@yahoo.com> > I checked the SC. It doesn't have Guaranteed Space. Willie, if the SC doesn't have Guaranteed Space, then there is no way to force hsm to recall a migrated dataset on the original volume (at least that I'm aware of). If your dataset would have had a SC with Guaranteed Space = Yes, then hsm would have recalled it on the same volume where it was allocated. And if the original volume is not there (for whatever reason) the recall would fail. If you have datasets with such a SC, you can test this yourself.
