For SMS managed data sets, EXPIREBV uses what is specified in the MGMTCLAS to determine when to delete old backup versions.
-----Original Message----- From: IBM Mainframe Discussion List [mailto:[EMAIL PROTECTED] On Behalf Of Larry Burch Sent: Thursday, December 21, 2006 9:58 AM To: [email protected] Subject: Re: Deleting HSM Backups questions David, DELVOL is what I meant when I said I had deleted a number of primary volumes. And, to my understanding, the "days" parameter for EXPIREBV says to delete only stuff that is *older* than "days". The manual says "If the age of such a backup version exceeds 'days', the EXPIREBV command deletes it." So my 1000days ought to delete a lot more than would 5000days. BUT! it had been a few weeks since I last looked at our EXPIREBV command that runs every weekend -- now I see that it says only "...(CATalogeddata (366))", *not* UNcatalogeddata. And I see strong evidence that it's been that way since at least 1991! (maybe 1986) Hmmm. I'll just add an UNcat clause. But these, and DELETEIFBACKEDUP, apply to *non*-SMS-managed datasets, and the vast majority of ours have always been SMS-managed. Also I see that our weekendly RECYCLE has been disabled since at least 1999. Guess I'll just give it a few more tries and see what happens. Larry M.
