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

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 nonrestartable wait state X'0E8'.

Operator response
Record the wait state PSW.  Notify the system

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