REMODEL statement

The REMODEL statement recreates the ABR Model DSCB after it has been accidentally scratched or modified on a volume that was previously initialized for ABR. It can also be used to reset ABR volume backup information if the ABR Model DSCB is back-leveled (restored by other than FDR or ABR). A separate REMODEL statement is required for each volume to be processed.

REMODEL accepts most of the operands that ABRINIT accepts, plus some additional operands used to specify current ABR backup information. REMODEL rebuilds the ABR Model DSCB, but does not do anything to the other Format 1 DSCBs in the VTOC.

Important

If you restore a volume with Stand Alone Restore (SAR) (see SAR-Stand-Alone-Restore), the ABR backup information in the ABR Model DSCB is back-leveled. Use the REMODEL statement to reset the ABR Model DSCB to the current generation and cycle numbers indicated in the catalog. No operands except VOL and FORCE are required for this function.

Operands

All operands of REMODEL, with the exception of AUTOCYCLE=, EXPD=, EXDP2=, LASTGEN=, and LASTCYCLE= are also operands of the ABRINIT statement. See FDRABRM-ABRINIT-Statement for descriptions of operands BYPASSACS, CYCLE=, DATACLAS=, DISABLE=, ENABLE=, GEN=, HIGHTHRESHOLD=, LIST=, LOWTHRESHOLD=, MGMTCLAS=, RETPD=, RETPD2=, STORCLAS=, and VOL=. The FORCE operand has a different meaning here, so it is also described below.

REMODEL statement required operands

VOL=

(Required operand). Specifies the serial number of the DASD volume where the ABR Model DSCB is to be recreated.

REMODEL statement optional operands

AUTOCYCLE=

Specifies the most recent auto-cycle number (0 to 63) for this volume. (An auto-cycle is any backup cycle on which AUTOUPD=YES was specified or defaulted.)

If not specified, ABR searches the ABR catalog for the most current cycle and set AUTOCYCLE= to that value.

EXPD=

EXPD2=

Specifies the expiration date of the latest full volume backup (TYPE=FDR) as a Julian date (year plus day number) that may be in the form “yyyyddd” (for example, 2020123) or “yyddd” (for example, 20123). If the 2-digit year is used “yyddd”, year numbers less than 70 are assumed to be in the 21st century, for example, 20015=2020.015. For readability, a period may be inserted between the year and day (for example, 2020.123). EXPD= is the expiration of the latest COPY1 backup, and EXPD2= is for COPY2. If either or both are not specified, ABR sets the expiration by adding the retention period to today's date. These expiration dates are used by ABR when creating incremental backups if no expiration or retention period is specified for them.

LASTCYCLE=

LASTGEN=

The values specified are stored in the ABR Model DSCB as the generation and cycle number of the most recent backup of this volume created by ABR. The next ABR incremental backup creates the next higher cycle number (unless a full-volume backup is forced). The next full-volume backup creates the next higher generation number. Both parameters must be specified, or neither.

If LASTGEN= and LASTCYCLE= are not specified, FDRABRM searches the ABR catalog for the highest gen/cycle cataloged for this volume.

Warning

If OLDBACKUP is enabled on this volume and LASTGEN= specifies a value less than the most recently created generation for the volume, then the OLDBACKUP information on the volume becomes inaccurate.

FORCE

Specifies that ABR is to update the Model DSCB if it currently exists on the DASD volume. If not specified, ABR fails if the volume already contains an ABR Model DSCB.
