How Does Storage Management Affect Organizations?
• Storage affects many key
operational aspects of your
organization
• Application performance,
throughput, and availability
• Effective and efficient storage
device utilization
• CPU utilization & batch
processing
• DR planning: Backup &
Recovery, Data loss, Regulatory
compliance
How Does Storage Management Affect Organizations?
• Effects of Storage Issues can be easily masked or overlooked
• Performance impacts related to storage issues
• Growing requirements for CPU, storage devices and media: “cost of doing business”
• Planned outages (e.g. ICF Catalog maintenance) are a “necessary evil”
• Hidden problems that can cause unplanned outages or application failures
• Data Integrity - Failing/struggling DR exercises
How Does Storage Management Affect Organizations?
• Storage Administration Staff Stretched to Keep up
• Monitoring daily/weekly/monthly activity
• Device management
• “Process of elimination” problem resolution
• Wasted time on repetitive tasks
• Lack of time to research what’s going on in the
system
• Labor intensive activities such as backup & recovery
• Learning Curve
Common HSM Problems Part1 HSM Issues And Problems – The Importance of HSM Auditing and Reporting Tools
How Is My HSM Environment Running?
• How did last nights HSM processing go?
• Are repetitive migration failures
affecting performance daily?
• Are HSM migration policies in tune
with the current business
environment, or are they draining
CPU resources and wasting DASD?
Why Are HSM Tools Important?
➢Report on the success rate (and cost) in migrating and backing up what is expected daily✓Why? Not knowing the failures will lead to higher disk occupancy (and disk costs) and missing
backup (with business risks)
➢Make sure that all the tapes that HSM has been using over the last xx years are still present ✓Why? HSM and the tape Management System are isolated z/OS subsystems with no tight
integration and thus a high risk for inconsistencies
➢Have the best guarantee that all the controlling information for managing the migration and backups is still valid✓Why? When problems are unknown, invalid controlling information will only be visible when a
recall or a recover fails for a production user
➢Identify data sets that are constantly transported between disk and tape✓Why? “Thrashed data” can be a serious waste of resources inside HSM
Why Are HSM Tools Important?
➢Be sure that the daily time windows for migration and backup are sufficient to handle all DASD volumes✓Why? Unhandled volumes will probably not be handled tomorrow as well, read: data sets on
these volumes will never be migrated or backed up
➢Do not maintain migrated or backed up data that is no longer really required for business reasons✓Why? A large percentage of unneeded aged data makes the management by HSM much heavier
than can be justified by business reasons
➢Establish a quick and easy recovery procedure in case you ever lost an HSM migration tape or backup tape✓Why? As long as the tape has not been overridden, the controlling information for HSM can be
reconstructed but it is a very time consuming process with standard HSM tools
➢Reorganize the HSM control data sets when needed (= now), not at the end of the month✓Why? Standard reorganization processes lead to an application interruption
IBM Advanced Audit for DFSMShsm Overview
• All Audits Are Comprehensive and Fast➢Eliminates the need to execute
multiple audit commands for a single control data set
• Automated User-Selected Fixes➢Select fixes from a provided list or
create your own ➢Errors and fixes are organized by
error type in an ISPF panel
• Fix JCL and Commands are Automatically Generated➢Apply fixes to one, some, or all data
sets in a problem class
• Quickly Verifies the Integrity of DFSMShsm Metadata➢ The ability to recall data➢ The ability to recover data
• The ability to recycle tapeAuditsfor the MCDS, BCDS and OCDS➢Verifies contents➢Identifies inconsistencies and errors ➢Compares contents to catalogs and
tape management inventory➢ s➢ Identifies out-of-sync conditions
with other metadata
IBM Advanced HSM Reporter Overview
• HSM Control Data Set (CDS) Reporting • Visualize record contents in the CDSs• Filter and sort by:
• Size • Migration status• Backup versions • Other …
• Customized criteria• Identify data sets by creation date• Identify by migration date• Identify by last used date• Identify by size• Identify by recall thrashing• Other …
• HSM Health Reports• Reports status of HSM automatic functions
(volume oriented)
• HSM LOGX/Y Reporting • Report on HSM activity performed since
the last SWAPLOG and found in the LOGY dataset
• A SWAPLOG is usually performed daily or when log is full
• An exact copy of the LOGY file is required• Many LOGY datasets can be concatenated for
analysis
• Report on historical information• Migration / recall activities• Backup / recovery activities• Other
• Planning and trending reporting

Information• Ability to recover volume or single data set
Common HSM Problems Part2 I Have Way Too Many HSM Tapes In My Data Center
IBM Advanced Archive for DFSMShsm
Archiving Aging HSM Data to the Cloud and reducing costs and HSM clutter• Enables new storage tier in the ILM hierarchy which is
not directly managed by DFSMShsm
• Archived data will be cataloged and removed from MCDS• Optionally remove associated BCDS entries• OCDS entries will also be cleaned up as data is
moved from DFSMShsm managed tape
• Directly processes the DFSMShsm control datasets and ML2 tapes, no additional DFSMShsm overhead is incurred
• Coordinates file movement to the cloud based on batch job parameters
• Automatically pulls the requested file back from the object store and writes it to a DFSMShsm ML2 tape
• Updates MCDS and OCDS on recall from cloud
• Initiates a standard DFSMShsm recall for the file
• Benefits:
• Reduce the TCO of DFSMShsm by:• Reducing DFSMShsm managed inventory• Reducing cost of storage
• Allows less frequent DFSMShsm processing saving CPU cycles
• Consolidates Archive Tapes that are underutilized
• No DASD H/W vendor requirement – it’s software

DFSMShsm
• Aged data moves between active disk to other levels
• ML1 compressed data on disk
• ML2 compressed data on tape
• Compressed data reduces space --> less cost
• Tape is less expensive than disk, but what is happening with all that ML2 data?

Recognize Your Risks
ICF Catalogs Are Extremely Critical
to z/OS
All current and migrated data is
cataloged
Cataloged data is not accessible if the catalog is not available
What Makes This Critical? You
Probably Have:
A very high number of data
sets
A very low number of catalogs

Catalog Data Distribution
➢ You have hundreds of thousands of data sets
➢ They are cataloged across 20-50 catalogs
➢ Yet the majority of your data sets could be cataloged in as few as 2-3 catalogs
➢ An unplanned outage or catastrophic failure of one catalog could result in significant downtime for critical business applications
Move Entries While Data Sets Are in Use
➢Processes an alias level where data sets are open to move them non-disruptively from one catalog to another
➢One alias level can be processed at a time
➢Communications with all systems in a sysplex sharing access to the catalog whose entries are to be moved must be established
➢A communications started task within ACM is required to be running on all systems sharing the catalogs
➢Complete integrity is maintained for all data sets
➢Restart capability supported for WHILE-OPEN processing
➢Simulation capability allows advance testing and error correction

Catalog Problems
Things Go Bump in the Night …
➢Volumes crash and have to be restored
➢Catalogs (BCSs and VVDSs) become corrupted and have to be restored
➢Data sets become uncataloged, don’t ever get cataloged, or are cataloged to the wrong catalog
➢Data sets are cataloged, but don’t exist
➢CAS or caching problems

➢Insufficient disk space allocations
➢Unavailable DASD extents
➢Out-of-space conditions
Provides enhanced allocation management (EAM) features to provide centralized control of DASD volume usage and standardized allocation attributes
Provides the option of advanced volume selection (AVS) for a non-SMS managed data set at initial allocation time to enforce standards
Provides volume group support that enables you to define DASD groups from which to select additional volumes as needed
Features
Space Related Abends Sx37
➢Are a very common situation in batch processing
➢Have a very disruptive impact for Service Level Agreements and deadlines
Some Typical Error Situations:
➢Requested Amount of Primary Space is not available
➢Secondary Space is needed but not defined
➢Requested Amount of Secondary Space is not available
➢The current volume is out-of-space and more volumes are needed
➢Set rules for the allocation of space on the additional volumes
➢Duplicate Catalog Entry
Tivoli Advanced Allocation Management (TAAM) works with a rule-based mechamism:
➢Set the default handling rules for the enabled error situations
➢Define up to 30+ filters for datasets to be intercepted by TAAM
➢With individual handling rules and overrides of the defaults
Advanced Allocation Manager
➢ Avoid and recover from X37 type abends and NOTCAT2 situations
➢ Handles all DASD data sets, both SMS and non SMS-managed
➢ Maximizes use of the current volume before attempting to allocate additional volumes
➢ Limits fragmentation
