HSM autobackup comes along and will not backup these dataset(s) again unless changed in the interim (assuming you have HSM set to INCREMENTAL). HSM dumps can also have the same effect if you have RESET in the appropriate DUMPCLASS. BEWARE!

You are only supposed to use it at IBM's request but it seems that you are at the point anyway. • PATCH .BGCB.+24 X'FF' • Used to determine why SMS-managed data sets are not being selected during volume backup • These patches produce a lot of messages • ARC1245I with Reason Codes GT 90 for migrations • ARC1334I with Reason Codes GT 90 for backups I've not used it so personally so exercise some caution and give it a whirl on your sysprog lpar first after you've checked it out. Also i've a vague memory of an issue with volume dump jobs running against packs (or it might have been defrag/compactor type jobs ) which is re-setting the dataset backed up flag in the vtoc so hsm wont back it up. So i would check what activity went on against the pack in question where your dsn didnt get backed up in the time between dsn creation and hsm backup. Regards Dave *********************************************************************************************** Richard, The two datasets are in the same management class in the same storage group but on different packs.

Are they on different SMS groups or different non-SMS volumes? If they are separated are you allowing HSM to perform autobackup on both entities?

Schlecht Sent: Monday, July 15, 2013 6:54 PM To: IBM-MAIN@LISTSERV.UA.EDU Subject: Re: Missing HSM backups We have two lpars plexed, sharing DASD and catalogs and run HSM on each. Lpar-1 is supposed to handle the backups. Lpar-1: AUTOBACKUPSTART(1700 1800 1900) Lpar-2: AUTOBACKUPSTART(0000 0000 0000) Backups start at 17:00 and typically end around 17:11, hence, it seems sufficient time is provided. David G.

Schlecht Sent: Monday, July 15, 2013 9:17 AM To: IBM-MAIN@LISTSERV.UA.EDU Subject: Re: Missing HSM backups A new wrinkle and possibly related. I have a job that creates two GDGs in the same Management Class. Both should be backed up. However, one gets backed up while the other doesn't. The backup for the first shows up in HSM's job logs at the point of backup but the second is entirely absent from HSM logs. Even if HSM is having trouble backing up a dataset, shouldn't it be showing up in the job logs? David G.
