Magnetic tape still plays a key role in the z/OS storage hierarchy, and tape hardware vendors are continuing to develop advanced products, with increasing capacity and performance.
As a result, in addition to stand-alone tape and cartridge drives, which have formed the basis of tape media usage for the past 4 decades, z/OS shops now increasingly use Virtual Tape Systems (VTSs) for their tape handling needs.
In order to take advantage of the gains in price and performance, users installing a VTS need to migrate their stand-alone tapes into the VTS system, while existing VTS users occasionally need to migrate data between VTS systems, for example when installing or upgrading new hardware.
FATSCOPY is an easy-to-use, high-performance z/OS tape copy, consolidation, migration and conversion utility that can automate the process of copying and recataloging tape-based data sets from one tape media to another, including Virtual Tape, Vtape and VTS systems.
FATSCOPY can also be used for copying data between VTS systems of the same hardware vendor, or of different vendors. It supports “tape-based” and “tape-less” systems, including the IBM TS7700, Oracle Sun VSM, EMC DLm, Bus-Tech MDL, Fujitsu Centricstor and Hitachi VTF.
When migrating from one VTS to another, the VIRTTYPE and PHYSVOL keywords (4.9/25 and above) can minimise the number of physical tape mounts by selecting and copying all of the virtual tape volumes on a physical tape, which ensures that each source physical tape is mounted only once during the copy process.Extensive Hardware Support
FATSCOPY will automatically stack and consolidate files onto the output tape (s) and recatalog the moved files to the new tape(s). The flexible selection criteria allow you to select by dataset name prefix, volume prefix (or ranges) and by catalog device type.
FATSCOPY supports the copying of backup tape files belonging to FDRABR, and backup/migration tape files belonging to DFSMShsm.Key Uses
- FATSCOPY can CONVERT tape datasets from one magnetic media type to another.
Use FATSCOPY to automate the migration of tape datasets from one tape media type to another.
- FATSCOPY can STACK tape datasets on high-capacity volumes.
Use FATSCOPY to periodically move (and recatalog) tape datasets from multiple tapes and consolidate them onto fewer tapes.
FATSCOPY offers two main modes of operation:
- Volume Level – where the copying of tape datasets is
driven by specific or generic tape volsers.
- Dataset Level – where the copying is driven by specific or generic dataset names, located via the z/OS catalogs.
Additional criteria can also be used to modify the selection/exclusion process:
- Tape device type (DEVTYPE).
- File Sequence numbers (FILESEQ).
- Creation Date, Expiration Date or Size (in MB) of the tape files.
- The name of the job, step or program that created or last used the tape files.
Once selected, the input datasets are dynamically allocated by FATSCOPY and then copied to consecutive files on the output tape. Files from multiple tapes, but with like expiry dates, can be placed onto the same output tape.
The FATSCOPY functions described above can be executed either through standard z/OS JCL, or through a set of ISPF panels.
See the Technical Detail section for more information.
Interaction With Tape Management
FATSCOPY includes interfaces to IBM’s DFSMSrmm and Computer Associates’ CA-1 and TLMS, which allow it to gain access to complete information about the tape volumes and data sets that it is copying. Information recorded in the Tape Management System can be propagated to the Tape Management records of the output data sets. The input tapes can be optionally returned to scratch status.Flexible Licensing
If you have long-term management requirements or short-term migration needs we can help. FATSCOPY can be licensed under a range of cost effective options, catering for both long-term usage and short-term projects.Checkpoint Restart, Auditing Reports and Simulate
FATSCOPY also includes features for checkpointing, auditing and simulation:
- Checkpoint Restart: A FATSCOPY job can be restarted at any time if the
previous job is cancelled.
- Audit Report: FATSCOPY creates an Audit Report containing information
for each data set copied.
See the Technical Detail section for an example audit report.
- Simulate: This produces detailed reports showing the data sets that would be selected for copying and those that would be bypassed, based on the select/exclude criteria provided. For those data sets that meet the selection criteria, FATSCOPY produces a report showing how they will be grouped on the output volumes, the expiration date that will be assigned, the number of compressed and uncompressed output tapes that would be required, and a list showing the input tapes that would be requested during the copy process.
FATSCOPY also includes FATS/FATAR, which provides the following additional “media” and “data” functions:
Media functions —
- TAPE ERASURE. Quickly and securely erase full or partial tapes before they leave the safe confines of your data center.
- TAPE CERTIFICATION. Meet audit requirements by verifying the quality of your tape media and certifying the readability of your tape-based data.
- TAPE RECOVERY. Recover data from tape errors, data checks and improperly closed tapes.
- TAPE MAPPING. Map a tape to verify its characteristics and contents - the files, the filenames, DCB characteristics, blocksizes, creation and expiration dates, compression statistics.
- TAPE COPY. Copy a tape, either an exact “bit-for-bit” image, or a “logical” copy, which allows you to rename, reblock, and selectively copy files.
See the FATS/FATAR Product Portfolio Sheet for more information on tape media functions.
