DFSMS HSM

Showing 96

BLKSize of 16KB is much less than TapeBlkSZLim of 256K

DFSMShsm only writes 16K-Blocks to Tape,both for Migration and Backup.Many of our files are greater ones, which would participate much of larger block sizes.

Automatic Backup for UNIX-Files

DFSMShsm in FILE-Mode (for UNIX-Files) should support automatic backup like CLASSIC-Mode. SETSYS INUSE should also be considered because files are often in use.
over 3 years ago in z/OS / DFSMS HSM 2 Future consideration

Change HSM Filemode Messages to something different from ARCxxxx to differentiate automation procedures from HSM Classic.

When HSM Classic and Filemode are running as separate tasks and message driven automation is used for things like CDS backups and archiving PDAs and LOGs, compex code is needed to differentiate between the two due to the fact the messages from bot...

hbdelete - deleting Unix Directories recursively

We need an option with hbdelete to delete a whole directory with all files and sub-directories. Like option -X for hlist, the same option could be implemented for hbdelete. e.g. hbdelete -aX /u/iz01715/All files and sub-directories will be deleted...

Graphic interface for backup/restore USS files with DFSMShsm or "-pick" option similar to TSM-client

Additionally to the commando interface for backup/restore of USS-files with DFSMShsm it would be very useful for endusers, who use only ssh-connect to USS on z/OS, to have any kind of graphish interface to backup/restore of USS-files similar to TS...

HSM FLB support of archive function

The current set of available functions does not allow to 'archive' a file

Assign WLM Service Classes to DFHSM Sub-tasks

We would like a way to assign different WLM service classes to DFHSM subtasks. Specifically we'd like to assign RECALLs to a high importance/velocity service class and MIGRATEs to a lower importance/velocity service class. Can this be done while t...

Maximum same GDG parallel recall

In an GDG Extended environment, concurrent recall of too many (up to 999) GDSs may cause issues, the main ones being:1) Flood HSM recall queue with too many recalls, which can be:Too fast: With BATCH_RCLMIGDS(PARALLEL) in ALLOCxx all 999 recalls w...

DFSMShsm full volume dump is still limited to 40 volumes

During our HSM space management, we have defined one dump class, which runs once a week. At this dump class, we have included our large application development department volumes (EAVs with 1182006 Cylinders per Volume). During our last full volum...

Add Compaction information to HSM FSR SMF records

The SMF type 14/15 records normally contain the information about whether sequential data sets are compressed or not, and if they are, what type of compression as used. However, HSM uses DSS to process sequential data sets from Primary devices - D...
