Analyze a System Error

To find a system error, record the system error number from the message (for example, 000101) and then use the system error number to search for the system error.

Once you locate the system error, you will notice that the system error number is framed in a box for quick access. Below each system error you will find the following pieces of information to help you analyze it.

System Services Control Point (SSCP) System Errors

System errors 000500-000517 relate to the system services control point (SSCP) function of SNA support. Many of the problem determination portions of the system error formats refer to the resource vector table (RVT) data contained in a block on level 6. This information is valid only if the resource identifier (RID) of the NODE in error is valid. The layout of the 128-byte block for these dumps follows here.

Position
Definition

000
RVT1/RVT2 ADDR OF INPUT NODE

008
RID OF INPUT NODE

012
RVT1/RVT2 DATA OF INPUT NODE

040
RVT1/RVT2 ADDR OF CONTROLLING NODE

048
RID OF CONTROLLING NODE

050
RVT1/RVT2 DATA OF CONTROLLING NODE

092
SAVE AREA FOR R0 THROUGH R7 ON ENTRY TO SEGMENT (CSDP) ACCUMULATING ABOVE DATA.

To further aid in troubleshooting an SSCP problem, the path information unit (PIU) trace block at the time of the failure is also recorded in the dump. This is done only if PIU trace is active for the Network Control Program (NCP) producing the error. The PIU data starts in decimal location 032, X'20'. In location 008 of the block is a pointer to the last entry recorded. This block is on level 3.

System Error Example

The following is an example of how system errors and their associated information are presented.


000101

Program: CCSNA1(CS01, CS07, CSX4)

Error Message: CONDITION CODE 1 RETURN TO SIOSC

Explanation: An SIOSC macro was issued and a condition code 1 that was not valid was received from CIO. The SIOSC macro processor in IPLB segment CCIO should only be returning a condition code of:

System Action: A catastrophic system error is issued. The system performs an IPL.

User Response: See a system programmer to investigate the problem. The problem may be a logic error in CIO.
