Review this entire form before starting the procedure to create a backup
system diskette. Unit operating procedures are described in the
3270
Information Display System: Operator's Guide, GA27-2890.
These procedures duplicate the existing system diskette. If you do not get
the expected result in any step, start over at step
1.
If you have the same
problem a second time, check with your supervisor, or follow your local
procedures.
There are four indicators, labeled 8421, on the 3274 control panel. The
meanings of the 8421 indicator codes are shown in Figures 6-5 and 6-6. If
an error occurs during this procedure, the 8421 indicator codes may aid in
locating the cause. Within this form, an On indicator is called a 1, an Off
indicator a 0 (zero).
