DFHSM ARCPRPDO should produce better details in the sysprint

Currently if the ARCPRPDO does not find any records, it only puts out the sysin input: CONTROL PARMS FROM SYSIN: COMPACT START(17175,080000) END(17175,110000) It would be better to provide better details in the output.

DFSMShsm won't partrel multivolume SMS data sets

DFSMShsm should honor what is coded on the management class for the Partial Release attribute for multivolume SMS datasets to release unused space. Presently, DFSMShsm will not release unused space on multivolume SMS datasets during the Space Mana...

The zHSM ARCCMDxx Member provides the following option within the DUMP command and request is to increase the Limit of 255 to 300 or 350/ IBM provides the hardware Compression feature and that utilizes zEDC feature, so I would assume that IBM DF/S...

DFSMSHSM - remove reliance on ML1 for VTOC backups

We are no longer using migration level 1 for migrated data so we want to remove all ML1 volumes, however these are still required for VTOC backups. We do not see a need for VTOC backups as we would never use them for recovery but there does not ap...

manual Pairing for DFSMShsm frbackup

We use the frbackup command for copying our DB2 Environment in a new SYSPLEX. Therefor it is necessary that the first Volume of the source SG is copied to the first Volume in the backup Pool. The HSM make these Pairing more or less randomized. So ...

DB2 Backup System, timely release SYSPITR lock when Backup fails

!!!! Not able to select the appropiate Produkt, therefore select a random produkt. Produkt should be DB2 for z/OS !!!! When SYSPITR lock is held too long this can lead to Groupbufferpool shortages and DB2 is unable to perform GRECP/LPL recovery. S...
almost 6 years ago in z/OS / DFSMS HSM 3 Planned for future release

HSM needs to be able to COPY DUMP VOLUMES and update the BCDS. This is media change like moving from one VTS to Another VTS.

When Migrating to different MEDIA in HSM RECYCLE can be used to move ML2 and BACKUP volumes. The DUMP VOLUMES have no way to be moved where the CDS is updated also. Over the years in doing mergers, splits, and media upgrades this is always a issue...

Protect HSM expiration functions in IPL date error situation

We had a recent experience where one of our systems was IPL'ed to a future date. Unfortunately, RMM and HSM recycle processing ran during this time resulting in data being deleted prior to the true expiration date. We are able to change the RMM IP...

Prioritize On Demand Migrations / SHARE Req#SSMVSS14001

When a volume exceeds the high threshold the ENF72 message will trigger an ON Demand Migration for that volume. In our environment we have many PROD volumes that exceed the high threshold, but at the same time we also have many TEST volumes that e...
