Processor Halt Codes Manual

If the problem recurs during the processor dump, contact your service provider or the Global
NonStop Solution Center (GNSC), as directed by your local operating procedures.
%100526
Cause
This halt code occurs is combination with a status message indicating that a Power-On Self Test
(POST) operation has completed successfully. A POST operation occurs whenever power is
applied to a customer-replaceable unit (CRU).
Effect
The processor halts. The rest of the system is not affected.
Recovery. Whether or not a hardware recovery operation is required depends on what caused
the message to be generated.
The following table describes the most common instances that cause the POST message to be
generated and the subsequent recovery actions that need to be executed.
Required RecoveryEffectCause
The user knows that a CRU has been
inserted.
A POST operation is executed by the
CRU.
User inserts a CRU into an enclosure.
The message is expected. No action
is required.
A “POST has successfully completed”
message is generated for the CRU.
The user knows that power has been
applied to an enclosure.
A POST operation is executed by
each CRU in the enclosure.
User applies power to an enclosure,
initiating a power-on cycle for each
CRU in the enclosure.
The message is expected. No action
is required.
A “POST has successfully completed”
message is generated (for each CRU).
Determine the duration of the power
failure.
The service processor (SP) turns the
enclosure off.
Power-fail event occurs for a
processor.
To determine the duration of the power
failure, check for messages indicating
When power is restored, a POST
operation is executed by each CRU
in the enclosure.
The duration of the event exceeds
both the configured
1
ride-through time
and the expected
2
battery life for the
batteries supporting the enclosure.
when the power failed and when it
was restored.
The message is expected. No action
is required.
A “POST has successfully completed”
message is generated (for each CRU).
Determine if there are any messages
indicating that the batteries are bad.
When power is restored, a POST
operation is not required. However,
Power-fail event occurs for a
processor.
Determine the duration of the power
failure.
if something is wrong with the
batteries supporting the enclosure,
once power is restored a POST
The duration of the event exceeds the
configured
1
ride-through time but not
the expected
2
battery life for the
batteries supporting the enclosure.
To determine the duration of the power
failure, check for messages indicating
operation is executed for each CRU
in the affected enclosures.
There is something wrong with the
batteries.
when the power failed and when it
was restored.
If battery failure is indicated, replace
the battery.
A “POST has successfully completed”
message is generated for each
operation.
The most common indication of
battery failure is when only one
enclosure in the system requires the
POST operation (the remaining
enclosures recovered successfully
from power on).
Note, both CPUs in the enclosure
must have the %100526 halt. If there
are several bad batteries in the
system each enclosure’s pair of CPUs
halts.
