Chapter 6. Backup System Diskette Generation Procedure - IBM 3274 Planning, Setup, And Customizing Manual

Chapter 6. Backup System Diskette Generation Procedure
Each 3274 Control Unit is shipped with two uncustomized system diskettes. You
customize one, using the initial customizing procedure in Chapter 4, and use it as the
primary system diskette. The second may be used as a duplicate of, or backup for, the
primary system diskette. A backup system diskette is generated by performing the
procedure on the recommended Backup System Diskette Form contained in this chapter.
The following information should be entered by the planner on the Backup System
Diskette Form:
1. The type of keyboard (typewriter or data entry) to be used by the operator.
Note: If using a 76- or 88-key Japanese English or Japanese Katakana keyboard,
specify the number of keys and keyboard type.
2. In step 1, the identification of each diskette to be used
3. In step 7, enter the response to sequence number 031 (number ofRPQ diskettes to
be used).
In addition to the form, this chapter also contains:
• Keyboard diagrams showing the valid key pOSitions for backup diskette generation
(Figures 6-1 and 6-2).
• A diagram showing how to insert diskettes into the 3274 Control Unit (Figure 6-3).
• A chart giving the meanings of and recommended actions for the operator codes that
may appear on the 3278 Display Station or 3279 Color Display Station during backup
diskette generation (Figure 6-4).
• Charts giving the meanings of and recommended actions for the 8421 indicator codes
that appear on the 3274 control panel during the customizing procedure (Figures 6-5
and 6-6).
• A chart giving the meanings of and recommended actions for the 8421 indicator codes
that could appear on the 3274 control panel during IML as a result of improper
backup diskette generation.
All the information listed above and the filled-in Backup System Diskette Form should be
given to the operator who is to perform this backup diskette generation at the 3278 or
3279 display station.
