0E8

Explanation
During nucleus initialization program (NIP) processing, the machine check handler (MCH) resource
initialization module (RIM) failed.

The right-most four bytes of the program status word (PSW) have the following format:
x01rrwww
x02rrwww
x03rrwww
where: 

x

Irrelevant information.

1rr, 2rr, 3rr

A hexadecimal return code indicating the reason for the failure.

www

The wait state code.

 The return code is one of the following: 

1rr

A request to allocate MCH control blocks returned nonzero return code
rr.

2rr

A request to initialize the control registers returned nonzero return code
rr.

3rr

A request for virtual storage returned nonzero return code rr.

System action
The system enters non-restartable wait state X'0E8'.

Operator response
Record the wait state PSW. Notify the system programmer. ReIPL the system.

If the system programmer requests it, obtain a stand-alone dump.

System programmer response
Search problem reporting databases for a fix for the problem. If no fix exists, contact the IBM® Support Center. Provide the stand-alone dump.
