The DFSMShsm control data sets contain information describing the status of the DFSMShsm managed data sets and volumes. Each control data set requires regular maintenance (backup and reorganization) and auditing to ensure the integrity of the data managed by DFSMShsm. The DFSMShsm product provides the AUDIT command to detect, report, diagnose, and often provide automated correction for discrepancies between the control data set, ICF user catalog, and DFSMShsm owned volumes. Mainstar: FastAudit family of products provides the same audit capabilities as with the DFSMShsm AUDIT command, but at faster speeds. Using the FastAudit products, the audits are comprehensive (perform multiple audits with one command), flexible, and easy to use. Audits of some, or all of the z/OS and OS/390 metadata environments can now be done frequently, even daily, to identify and resolve errors before they lead to data loss or failed access. This IBM Redbook outlines the tasks to use DFSMShsm Audit and the use of Mainstar's FastAudit program to manage your HSM environment.

DFSMShsm Fast Replication provides DFSMShsm management for the use of volume-level fast replication. Fast replication is made possible by exploiting the FlashCopy capability of the IBM Enterprise Storage Server. With this capability, a set of storage groups can be defined as a copy pool. The volumes in this pool are processed collectively, creating, via fast replication, backup versions that are managed by DFSMShsm. Recovery can be performed at the volume or copy pool level. This capability is designed to work specifically with DB2 Version 8 or later. With DFSMShsm Fast Replication, which provides a fast, easy-to-use backup and recovery solution, the backup and recovery of DB2-related copy pools can be managed by DFSMShsm. This IBM Redbook consists of a technical overview of the DFSMShsm Fast Replication function in z/OS V1R5 DFSMS. It provides you with the information that you need to understand and evaluate the function, along with practical implementation hints and tips. This book is written for storage professionals, database administrators, and system programmers who have experience with the components of DFSMS. It provides sufficient information for you to implement the DFSMShsm Fast Replication function in your storage environment.

DFSMShsm provides space, availability, and tape mount management functions in a storage device hierarchy for both system-managed, and non-system-managed storage environments. DFSMShsm allows you to automate your storage management tasks improving the productivity by effectively managing the storage devices. This IBM Redbook provides technical storage specialists and storage administrators with the basic DFSMShsm knowledge for implementing and customizing DFSMShsm at the 2.10 level. Hints and tips on the daily operation, monitoring, and tuning are included. Sysplex environment considerations are also included. Those implementing DFSMShsm for the first time will find valuable information for exploiting the DFSMShsm functions. Experienced persons will find that this redbook can be used as an update to the latest DFSMShsm functions, and it shows how to use those functions in an existing DFSMShsm installation. T

With z/OS® V1R7, DFSMShsm™ has been enhanced to support the new large format sequential data sets. This Technote provides an overview of this function.

How to Manage and Tune the DFSMShsm environment

This document describes how customers can take existing aggregate backup output files and utilize MVS utilities to stack multiple aggregates or multiple versions of the same aggregate onto a single tape and recover any of these (stacked) aggregates.
