TOPS VSN Log and alarm messages
0001/000A
Message:
[PRU_name] encountered a segment or mapper error. This is an
unrecoverable error and the PRU should be rebooted. If rebooting the PRU
does not solve the problem, reboot the SRU.
Description:
The software task failed because it encountered a segment or
mapping error. The PRU may declare itself faulty or recreate the task. If the
PRU declares itself faulty then the log subsystem detects the faulty condition
and raises an alarm.
Action:
Reboot the PRU. If this action does not correct the problem, then
reboot the SRU. If the error occurs more than once a week replace the SRU.
Document the problem and record all action taken.
0001/000B
Message:
[PRU_name] has been in a critical region too long. This is an
unrecoverable error and the PRU should be rebooted.
Description:
The software task failed due to a software error. The PRU may
declare itself faulty or recreate the task. If the PRU declares itself faulty then the
log subsystem detects the faulty condition and raises an alarm.
Action:
If the PRU is in the working state, no action is required. If the PRU is
in the faulty state, document the problem, restart the PRU, and then contact
NT.
0001/000C
Message:
[PRU_name] has encountered a parity error. This is an
unrecoverable error and the SRU should have diagnostics run.
Description:
The software task failed because of a parity error. The PRU may
declare itself faulty or recreate the task. If the PRU declares itself faulty then the
log subsystem detects the faulty condition and raises an alarm.
Action:
Run diagnostics on the SRU containing the PRU. To do this take all
other PRUs out of service first. If diagnostics fail, replace the SRU. If
diagnostics do not detect an error but the problem persists, replace the SRU.
Document the problem and record all action taken.
0001/000D
Message:
[PRU_name] encountered a kernel error. This is an unrecoverable
error and the SRU should be rebooted.
Description:
The software task failed because the kernel of the SRU in which
the PRU is operating has encountered an unexpected state. The PRU may
declare itself faulty or recreate the task. If the PRU declares itself faulty then the
log subsystem detects the faulty condition and raises an alarm.
Action:
Reboot the SRU. If the error occurs more than once a week replace
the SRU. Document the problem and record all action taken.
