DFSMS HSM

Showing 99

Expand RECYCLE command with a new parameter PART (NO/YES)

For DFHSM with HOSTTYPE=FILE only command backup is possible, therefore SETSYS PARTIALTAPE (BACKUP(MARKFULL)) has no effect. Most of virtuell backup volumes therefore remain at status PART. A RECYCLE command (for example: RECYCLE ALL EXECUTE PERCE...

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...

DFSMSHSM LIST DATASET with Cloud Object Name

We are able to get a list of the Cloud Containers / Buckets, migrated data sets, and listing of the Contain objects using the following: LIST CLOUD(cloudname) LIST LEVEL(x) LIST CLOUD(cloudname) CONTAINER(containername) Using these lists, it is st...

Allow users to determine actual HSM function run times from CDSs

We are trying to process DFSMShsm MCDS and BCDS to retrieve actual run times of HSM functions (primary space management, secondary space management, automatic backups and automatic dumps). There are complete time and date fields for every function...

Migration data sets distinguished by different importance of the data sets.

We would like to be able to customize characteristics of migration data sets distinguished by different importance of the data sets. Currently, there is no way to configure specific migration tape data set name for different sets of files.All tape...

Enhancement Recycle like process to help overcome the number of container restrictions for HSM TCT.

Enhancement ::We are looking at the possibility of an Recycle like process for datasets within a container.As the containers get old, there is possibility of data getting expired in them. This may result in containers holding very little/small num...

Allow ML2 parameter for the MIGRATE SG and MIGRATE VOLUME parameters.

Customers may encounter a situation where their HSM ML1 volumes have filled and yet they still need more space in the storage groups for production data. Customers can use the MIGRATE SG command or the MIGRATE VOLUME command. However, the ML2 subp...

Improve HSM ML1 migration volume selection by considering fragmentation

When HSM attempts to migrate a data set to an ML1 volume, it only considers free space available on the volume. Unfortunately, in an environment with large volume sizes (like 1TB EAV's), there can be a lot of free space available on a volume, but ...

Improve HSM messaging around ML1 data set migration failures

During ML1 migration, HSM selects a volume by examining the space available but it does not consider the fragmentation index for the volumes. In cases where there are many volumes (especially EAV's) with a lot of space available in the overall poo...

Allow ML1 DASD volume DEFRAG when HSM is active

Based on a Case that I had opened regarding the use of DFDSS DEFRAG and ML1 DASD volumes, IBM Support mentioned that "...if you want to do defrag the ML1 volumes, you should backup the ML1 volumes first and then shutdown HSM. You should not runnin...
