When I had a system, I had the HSM CDS backup datasets pre-allocated (4 each) on non-SMS volumes with sufficient space. DFHSM then rotated between them. This is the way the DFHSM starter set (there is sample JCL) originally set things up.
BCD's can grow significantly, especially if EXPIREBV is not run on a regular basis. My daily DFHSM maintenance job included three EXPIREBV commands. I also had it issue a few of the QUERY commands so that I usually didn't get surprised by these back-up space failures. > -----Original Message----- > From: IBM Mainframe Discussion List <IBM-MAIN@LISTSERV.UA.EDU> On > Behalf Of Matthew Stitt > Sent: Friday, December 20, 2024 10:26 AM > To: IBM-MAIN@LISTSERV.UA.EDU > Subject: Re: DFHSM error > > I used a simple copy to a larger dataset. > > Bring HSM down.
