Processor Halt Codes Manual

Effect
The processor halts. The rest of the system is unaffected.
Recovery
Refer to Processor Halt Monitoring and Recovery (page 10). Take a memory dump and contact
your service provider or the Global NonStop Solution Center (GNSC), as directed by your local
operating procedures.
%102520 MC_FAULT_PROCESS_PRIORITY_BOGUS
Cause
The millicode detected an incorrect process priority.
Effect
The processor halts. The rest of the system is unaffected.
Recovery
Refer to Processor Halt Monitoring and Recovery (page 10). Take a memory dump and contact
your service provider or the Global NonStop Solution Center (GNSC), as directed by your local
operating procedures.
%102521 MC_FAULT_SMP_IPU_FAILED_TO_START
Cause
Millicode detected that an IPU failed to start on a Coldload or Reload.
Effect
The processor halts. The rest of the system is unaffected.
Recovery
Refer to Processor Halt Monitoring and Recovery (page 10). Take a memory dump. After the
dump completes, perform a “Hard Reset" on this NonStop Kernel logical processor. This reset
can be accomplished using the Onboard Administrator (OA) or OSM Low-Level Link (LLL), to
ensure complete clean-up of and recovery from the failure. The processor can be reloaded after
it has come back up to the Power-On (PON) Halt (%100212 halt code). If the processor fails to
come back up to the PON Halt, then it must be replaced. If the subsequent attempt to reload the
processor results in another halt, then the processor should be scheduled for replacement at the
earliest convenience. Contact your service provider or the Global NonStop Solution Center
(GNSC), as directed by your local operating procedures.
%102522 MC_FAULT_MCHK_ABORT
Cause
A Machine Check Abort occurred.
Effect
The processor halts. The rest of the system is unaffected.
Recovery
Refer to Processor Halt Monitoring and Recovery (page 10). Take a memory dump. After the
dump completes, perform a “Hard Reset" on this NonStop Kernel logical processor. This reset
can be accomplished using the Onboard Administrator (OA) or OSM Low-Level Link (LLL), to
ensure complete clean-up of and recovery from the MCA. The processor can be reloaded after
it has come back up to the Power-On (PON) Halt (%100212 halt code). If the processor fails to
come back up to the PON Halt, then it must be replaced. If the subsequent attempt to reload the
processor results in another halt, then the processor should be scheduled for replacement at the
earliest convenience. Contact your service provider or the Global NonStop Solution Center
(GNSC), as directed by your local operating procedures.
