This is the screen presented after an UNEXPECTED ERROR has been found by the DCF. This is a major error; the diagnostic run cannot continue. This screen is an example. and should not be used for troubleshooting.

Note: The displayed RAC may have multiple causes. The ADDIT INFO zone (AREA and EXC.COD) then gives more detailed

DESCRIPTION OF FIELDS FOR UNEXPECTED DCF RAC

/~~

1\ .. ,}I

In catastrophic cases. such as erroneoUs logical status. or return code not null after an I/O operation. the diagnostic control facility (DCF) displays a screen containing a special repair action code (RAC) referring to an unexpected error.

These RACs may be requested by any DCF component:

• DCM: Diagnostic Control Monitor

• CP MOSS: Command Processor - MOSS

• CP CCU: Command Processor - CCU

• CP CSP: Command Processor - CSP

In principle. an unexpected error RAC is meaningful only in perfectly debugged code. Therefore. during an investigation into an unexpected error. as a last possibility. you should suspect a software error in the DCF.

The RAC lists on the following pages assume that the DCF is free of software errors. The error can be caused by any of the

following modules: diskette generation. diskette copy.

microcode interface tape (MCIT) transfer. or any software component external to the DCF.

CP Additional Inforaation Meaning

All RACs reported by each command processor (CP) are self-explanatory; there is no standard format.

DCM Additional Inforaation Meaning

Exercized

Exception Code Area

This area is structured as follows:

• The first line indicates the exercised area (AREA=) and the current operation exception code (EXC.COD=) in this area.

• The second line displays the logical DCF status at the time of the operation. It consists of a DCF message with the following format:

ON condition = wxyz where:

condition = DCF logical status wxyz = DCF value

AREA Code Area Name 00 Control code 01 Di skeHe 02 Panel MIOC 03 CCU IOC 04 Timer

AREA Code Exception Code list 00 (not used)

01 Disk adapter list 02 Panel adapter list 03 Panel adapter list 04 Timer adapter list

condition

ON condition AREA Meaning

ON EVENT/STATE 00 Event wx received on state yz is rejected.

ON ROUTINE 00 Routine wxyz (for example A801) does not exist in current 1FT section header

ON SST OFFSET 00 The offset wxyz in 1FT Sequence table is wrong.

ON (module name) Module or file: empty or not or 01 found, already open or closed ON (file name)

02 - wxyz reflects the last MIOC ON DATA XFER command sent.

03 - wxyz reflects the last DCM message sent to CPo
