System Error Summary, Part 1

Part 1 of the system error summary is a chronological listing of all machine checks and channel checks. IPL, restart (software), and termination records are included for MVS and VSE/Advanced Function operating systems.

Figure 1 shows an example of part 1 of the system error summary report.

The report is generated by CPU. This line contains the CPU model number, serial number, and a CPU indicator that corresponds to the CPU indicators used throughout the system exception reports.
 2 
This section presents records of system events. It appears only when the operating system is MVS or VSE/Advanced Function. The column headed by REASON contains the IPL or the restart ABEND reason code. The column headed by PROBABLE CAUSE contains an explanation of the code.

Possible termination reason codes are:

REASON PROBABLE CAUSE
EOD END-OF-DAY RECORD
EOP END OF PROCESSING FROM IOS
RESTARTABLE WAIT STATE
DF DEFAULT
MCH MACHINE CHECK FORCED TERMINATION
NONRESTARTABLE
NM NORMAL SYSTEM INITIALIZATION
RESTART ABEND CODE 071
 3 
This section appears when EREP encounters MCH records. MCH records are error records created when the machine check handler causes an interrupt as a result of an unsuccessful attempt to retry a failed instruction.

If the JOBNAME field is blank, the failure is within an operating system task.

Possible ERROR DESCRIPTIONS are:
  • BUFFER ERROR
  • EXTERNAL DAMAGE
  • HARD STORAGE ERROR
  • HIR SUCCESSFUL
  • INSTRUCTION PROCESSOR
  • INVALID LOGOUT
  • POWER WARNING
  • REGISTER OR PSW INVALID
  • STORAGE PROTECT KEY ERROR
  • SYSTEM DAMAGE
  • UNDEFINED ERROR
Possible PROBABLE FAILING UNITS are:
  • CHANNEL
  • CHANNEL/DIRECTOR
  • CONTROL UNIT
  • PROCESSOR
  • STORAGE
  • UNDEFINED
  • UNPROCESSED ENTRY
 4 
This section appears if EREP encounters CCH records. CCH records are error records created by the channel check handler when a channel error occurs.

If the JOBNAME field is blank, the failure is within an operating system task.

Possible ERROR DESCRIPTIONS are:
  • CHANNEL CONTROL CHECKS
  • CHANNEL CONTROL/INTERFACE CONTROL CHECKS
  • CHANNEL DATA/CHANNEL CONTROL CHECKS
  • CHANNEL DATA/CHANNEL CONTROL/INTERFACE CONTROL CHECKS
  • CHANNEL DATA CHECKS
  • CHANNEL DATA/INTERFACE CONTROL CHECKS
  • INTERFACE CONTROL CHECKS

Possible PROBABLE FAILING UNITS are the same as those shown in  3 .

EREP does not print out duplicates of records occurring together.
