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...

Make Keylabel persistent in ICF Catalog

We are at a stage where we are starting to have pervasive encryption. So we need to be able to know at any point in the life of a record, whether it is active or migrated, whether it is encrypted or not and what key was used. We need that for our...

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...

For Migrated IAM datasets Store IAMINFO and IAMAIX FPLs in the non-VSAM MIGRAT catalog entry that would indicate this is an IAM dataset and store associations (AIX/Path).

Right now, HSM does not work in full compatibility with IAM. HSM doesn’t understand the associations of the IAM data set. For example, if customer issues HDELETE for cluster, HSM only deleted Cluster not AIX/Path. To overcome from it, IAM issue DE...

HSM EXPIREBV to be part of Automated function

HSM to support multiple CMD members

Sometimes in DR situation, we will be needing special commands to be submitted when HSM comes up. For this, we can issue those via automation. But whenever there is an IPL or when HSM is recycled, those commands will be lost. Instead of depending ...
