4.7.6 Diagnostic Error Reports - Detailed error and command summary
•
information is printed on detection of an error. Additionally, tests
that perform error checking issue a "probable failing FRO" report. This
report identifies the first, second, third, and sometimes fourth most
likely failing FRO for the detected error; e.g., controller PCB, media,
read/write and clock PCB. The error report gives the operator
information such as:
•
•
• The last command
• The last address issued before failure detection
• Status information down to the bit level.
For a detected error, the program prints the error PC, AC
O,
1, and
2 at the point of error, plus an option printout. The program then
goes into a scope loop between entries to .SETUP and .LOOP allowing the
operator to set SWPAK. In general the error PC points to a call error.
The option printout is done in one of the formats shown in Figure
4-24.
NOTE
The diagnostic program may or may not call out the correct
failing FRO. Further investigation may still be required
by referencing and then performing the procedure given in
the diagnostic flowcharts (refer to subsection 4.2)
