| SUPPORT FOR EAV VOLUMES |
FDR now support 3390 disks denoted as Extended Address Volumes (EAV). At present,
the size of EAV volumes is greater than 54GB and up to 223GB). EAV volumes will be
identified in FDR messages and in reports as “3390-A”. FDR V5.4 level 70
is required if it is executed on z/OS 1.10 with EAV volumes. Extended Address Volumes
(EAV) required changes in many components of FDR, so it impacts almost all FDR functions.
A new map layout has been added to FDRCPK to allow for expanded fields and counts.
In addition, the summary fields will show the summary values in megabytes (M) if the
value exceeds 999,999.
A number of new FDREPORT fields have been added to support EAV volumes at the volume level
including those for cylinder managed and track managed space as well as F8 and F9 DSCB counts.
For a list of all the variables, see FDR Documentation Section 54. |
| MAXFILE PARM NOW SUPPORTS 65534 FILES |
The maximum number of files that can be created on a multi-file backup tape
has been increased from 4095 to 65534. This value can be set in the FDR
Global Options field MAXFILES. |
| ADDITIONAL FIELDS TO FDREPORT FOR DFDSSHSM BCDS AND MCDS |
FDREPORT performs multiple reads of the Control Data Sets required to give access
to the data for migrated or backed up datasets. Available BCDS data now includes
data from the current backup records consisting of the SMS status and classes as
well as the original device type. |
| VOLUME RETRY/BYPASS ABILITY ADDED TO FDREPORT |
In FDREPORT V5.4/67 the keywords RETRYLOOPS, RESWAITIME, and RESFAILRTNCD were
added to provide control over the number of retries against reserved online volumes,
the number of seconds to wait for online volume reserves, and the return code issued
when online volumes are bypassed on long term reserves. |
| ABILITY TO DISPLAY BYTE RELATED FIELDS IN GIGABYTES OR TERABYTES ADDED TO FDREPORT |
Alternate field formats for byte related fields are displayed with a qualifier
(e.g. nnnnn.dddk where “k” is the qualifier) of K (kilobytes), M (megabytes),
G (gigabytes), or T (terabytes). The field format is invoked by adding ENABLE=DECIMALBYTES
to a preceeding DEFAULT command or the active PRINT command. |
| Z/OS 1.10 SUPPORT |
FDR V5.4 level 68 is required if it is executed on z/OS 1.10 unless EAV volumes are being used. |
| ICFCORE STORAGE GETMAINED ABOVE-THE-LINE |
The GETMAIN for the ICFCORE storage was moved above-the-line for FDR V5.4/67 and above when RTC=YES is specified. |
| FDRINSTANT NOW SUPPORTS “SPACE EFFICIENT” (SE) FLASHCOPY |
The use of SPACE EFFICIENT volumes as a FlashCopy target is transparently supported by FDRINSTANT V5.4/62
and above. FDRINSTANT will automatically detect a SPACE EFFICIENT FLASHUNIT designation and
appropriately establish the FlashCopy relationship. |
| FDRINSTANT NOW SUPPORTS INCREMENTAL FLASHCOPY |
Incremental FlashCopy uses a “persistent” relationship to allow reduced overhead in copying and
restoring volumes when only a portion of the tracks have changed since a previous FlashCopy.
Incremental FlashCopy is invoked by adding the “FCOPY=INCR” to the main FCOPY statement.
This is supported by FDRINSTANT V5.4/62 and above. |
| FDRINSTANT NOW SUPPORTS FRR FLASHCOPY |
FCOPY=FRR can be specified on the FCOPY main control card to perform Fast Recovery
Restore (FRR) on the online source volume. |
| FDREPORT SEARCH METHODS IMPROVED |
The search techniques in FDREPORT have been improved to reduce the amount of
CPU processing time to over 50% savings than prior levels. |
| VSAMSCAN OPTION ADDED TO FDRQUERY REPORT |
The VSAMSCAN command is used to provide a fairly quick scan of selected disk
volume VTOCs looking for ICF/VSAM components. |
| CATERROR KEYWORD REMOVED FROM FDRARCH |
FDRARCH was changed in V5.4/60 to drop support for the CATERROR keyword.
To facilitate an orderly transition for those who have specified CATERROR
in their control statements, all command structures supporting CATERROR will
be passed through the obsolete conversion service. CATERROR=IGNORE and
CATERROR=PURGE will be converted to CATERROR=RETAIN and an FDR567 message
will be issued documenting the conversion. |
| NEW ABR UTILITY TO COMPARE STORAGE ENVIRONMENTS |
The FDRABRX program compares the current storage environment against a
snapshot created by a previous FDRABRX run to ensure the integrity of
your backups. This is useful when a “mixed environment” containing
other vendor's backup/restore utilities in addition to FDRABR.
See member FDRABRX in the FDR ICL library for more information. |
| TAPE MANAGEMENT SUPPORT ADDED TO FDRCRYFM |
Support has been added for the four major tape management systems in
addition to the IFNOTCURRENT keyword to allow the removal of old entries
in the FDRCRYPT keyfile. |
