020

Explanation
Reconfiguration initialization failed. The wait
state reason code specifies the error.
The right-most four bytes
of the program status word (PSW) have the following format: xrrrrwww
 where: x
Irrelevant information.
rrrr
A hexadecimal reason code indicating the reason for the failure.
www
The wait state code.

 The reason code (rrrr) is one of
the following: 0010
The service processor could not provide channel path information
to reconfiguration. This is a hardware problem.

System action
The system ends the initialization. The system
enters nonrestartable wait state X'020'.

Operator response
For reason code X'0010' or X'0030',
obtain a stand-alone dump. Contact hardware support, providing the
recorded contents of the wait state PSW. Check the processor controller.
Try to do a switch-over or reIPL. If this does not work, partition
the machine and use the side with a good service processor.
For
reason code X'0040', contact the system programmer.

System programmer response
For reason code X'0040',
search problem reporting databases for a fix for the problem. If no
fix exists, contact the IBM® Support
Center. Ask the operator to obtain the stand-alone dump and provide
it to IBM.
