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 ...

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...

Allow DFHSM to Migrate bad files with 0 exts

We have come across bad dsns(meaning files that have no lrecl, blocksize, 0 extents and/or are empty).DFHSM will bypass these types of files due to it having 0 extents. What is happening is even though they are still being cataloged. With these fi...

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...
