DFSMS HSM

Allow DFSMSHSM to provide Immutable option during bucket creation

We are using IBM Transparent Cloud Tiering and HSM to migrate data to the cloud. We have been questioned by our auditors if the data stored to the cloud is immutable. They want verification that once the data is written to the cloud, it cannot be ...

Fast Replication target volumes that have no UCB should be ignored

With FR the pool storage group(source) and the COPY POOL BACKUP storage group(target) must not contain predefined devices without UCB. Application data can grow very fast, so we use automated tasks that initialize new volumes. Unfortunatelly, when...

Change HSM HOST id from single character limit to multi-character

A multi-character HOST id would allow customers to customize ARCCMDxx commands to be unique by multiple system symbols like a combination of operating environment (Live or DR Test) and HSM address spaces. Example: HOST=&SYSENV.&HSMHOST HOS...

Add a possibility to limit the number of parallel tasks to prevent S878 ABENDing HSM STC

During recover of over 1000 datasets we increased the maximum recover tasks step by step to 12. Once we reached 12 HSM STC itself ABENDed because of a S878 because of a storage constraint below the line. This is documented as works-as-designed: ht...

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...

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...

DFSMShsm file mode host: truncated pathname in messages ARC1000I and ARC1001I

At the DD ARCLOG Output Dataset, we have seen several USS paths/files with three dots in the middle (they were truncated, because they are too long). We know that the whole path-/filename can be displayed via the smf fsr record. However, for audit...

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...

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...

HSM improvement related to the ARCMDEXT EXIT and new parameter request

The Itau bank has 2 very large Sysplexes Bank and Cards.The Bank environment has a heavy batch workload that relies on the HSM task. The batch processing has a lot of GDG datasets.The Itau is using the EXIT ARCMDEXT to inform the HSM during the mi...
