DFSMS HSM

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...

DFHSM CDS Reorganization's interval

We conduct periodic REORGANIZATION of the CDS DATA SET in DFHSM and stop DFHSM on each occasion. We don't want to implement the reorganization as our customer system is 24/7. CA reclaim function might reduce the intervals of reorganizations, but w...

Increase limit of 18 volumes for HSM CDS backup to 59 as it is for z/OS.

During CDS backup HSM could not locate the oldest backup copy of a cds and issued misleading message ARC0744E RC36 REAS8 telling there is a catalog problem. IBM support found the number of volumes of the cds backup copy to be limited to 18. IBM wi...

HLIST VOLUME - more accurate listing in HSM PLEX

In HSMPLEX environment, ADDVOL ML1 SDSP settings are applied for specific LPAR only, but the HLIST VOLUME from another LPAR lists SDSP=YES (ADDVOL ML1 SDSP was not submitted on that other LPAR)

Unable to cancel recall request during shutdown

During shutdown of DFHSM on a Lpar (using CRQ), this DFHSM can be processing a recall request for a very large dataset causing DFHSM not to shutdown until the dataset is recalled. We must be able to intervene in a DFHSM instance that is shutting d...

DFHSM volume selection for CIDS allocation needs to check for contiguous space availability

This item requests DFHSM to check for enough contiguous space when selecting a volume for allocation of the CIDS. During the processing of the FRBACKUP command, one catalog information data set CIDS is created for each copy pool version. Each CIDS...

Allow the LASTCOPY of Copypool backup to expire

Currently, DFHSM will not "EXPIRE" the last copy of a Copypool backup. It flags the tapes as EXPIRE but does not truly expire the tapes. Manual commands must be executed in order to truly expire the backup tapes of the last copy of a copypool.

Add option BACKUP to HMIG command.

Add option BACKUP to command HMIG that backs up a DSN to a HSM backup volume if none is present, then migrates the dataset to a migrate volume.

Include functionality for tape optimization in HSM during dataset recovery from FRBACKUP DUMP tape volumes

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.
