FDRABRM ISPF Interface

Most of the functions of FDRABRM, the ABR VTOC maintenance utility, can be executed using the ABR ISPF dialogs. The dialog can also be used to simply display the ABR status of online DASD volumes. Assuming that option A on your ISPF main menu gets you to the ABR dialogs, from the main menu enter: A.I.8

Set ABR Disk Volume Processing Options #1 – Panel A.I.8

The result of this dialog is to submit a batch job to execute FDRABRM with the proper control statements. On this panel, specify the name (and optional volume serial if not cataloged) of the FDR program library, the SYSOUT class to which output is to be directed (usually asterisk (*)) and update the JOB statement displayed to be acceptable for your installation. When done, press ENTER to continue and display this panel:

ISPF Panel A.I.8

Set ABR Disk Volume Processing Options #2 – Panel A.I.8

The fields toward the right of the panel correspond to many of the operands of the ABRINIT, MAINT, and REMODEL statements; the values shown are the defaults in effect. The cursor is positioned in the “Volume Serial Number” column. To display the actual ABR status of one or more DASD volumes, you can enter one of:

• A volume serial, such as PROD01
• A prefix followed by an asterisk (*), such as PROD*, to display all volumes starting with that prefix
• An asterisk (*) to display all online DASD volumes (this may be time consuming if you have a great many online volumes).

Press ENTER to display a panel such as:

Set ABR Disk Volume Processing Options #2 – Panel A.I.8

This shows the current ABR status of the selected volumes. To add more volumes to the display, type another serial or prefix in the blank line at the bottom.

The CMD field accepts commands similar to ISPF EDIT: I or In inserts “n” blank lines where new serials can be entered. R or Rn replicates the selected line “n” times. D or Dn deletes one or more lines.

In the fields headed “---Current Backup---”, the status of the most recent backups of the volume are shown; these are extracted from the ABR Model DSCB on the volume. The most recent generation and cycle numbers, the expiration dates of the most recent full-volume backups (EXPDT for COPY1 and EXPD2 for COPY2 if it was created), and the current auto-cycle count are shown. If the volume has not been initialized for ABR processing (no ABR Model DSCB in the VTOC), “NO MODEL” is shown. A volume that was initialized for ABR but has never had a full-volume backup taken shows “NO BKUP”.

These fields are normally for reference only. However, if they have somehow become inaccurate or back-leveled (such as a stand-alone restore (SAR) of the volume), you can overtype them with the proper values. However, if you do so you must also change the column labeled “MOD” to “YES”; otherwise the changes are not accepted.

The rest of the fields (except FORCE) represent the ABR initialization options for the volume. For an initialized volume, they are the actual values extracted from the ABR Model DSCB and you can over type any of them to change them. For an uninitialized volume, they are the default values that you can accept or over type to change.

Enter YES in the FORCE column if an attempt to initialize or maintain a volume has failed (see the description of the FORCE operand under the various FDRABRM statements earlier in this section to see if FORCE is appropriate). FORCE is required if you have copied data sets from other ABR-managed volumes to this volume before initializing it for ABR.

When you type SUBMIT or EDIT on the command line, the dialog generates an FDRABRM job stream. It includes ABRINIT statements for any displayed uninitialized volumes, MAINT statements for any initialized volumes whose options you have changed, and REMODEL statements for any initialized volumes whose current backup information you have modified. EDIT gives you a chance to review and modify the job stream before submission.

To exclude volumes from processing, simply delete them from the display (the D line command) before entering SUBMIT or EDIT.
