The system creates the reports from the logs of the maintenance subsystem. The
subsystem monitors the system hardware and logs problems as errors or alarms.
The type of alarm indicates the impact of the problem, as defined below:
Warning alarm
—A minor interference which does not noticeably impair service.
Minor alarm
—A problem which could disable a local area of the system and
noticeably impair service.
Major alarm
—A problem which widely degrades the system and seriously
impairs service. The system automatically calls INADS to report major alarms.
Resolved alarm
—A problem which has been corrected, and the system is
correctly functioning. The system stamps resolved alarms with the date and time
the problem was corrected. The system handles any errors associated with the
alarms as “resolved.”
System Reboots and the Alarm Logs
The system saves the Alarm and Error logs to the memory card if any of the
following events occur:
—The
save translation
command is executed.
— Translations are saved as part of scheduled maintenance.
— A reboot takes place.
— The PPN is about to lose all power after having been on battery backup.
The attempt to save the alarm and error logs may be unsuccessful if the MSS is
not available.
Whenever the system reboots, the logs are restored from the SPE disk that
becomes active with the reboot. Since the logs are saved to the disk on the SPE
that was active
before
the reboot, the versions restored at reboot time may not be
current. This condition occurs if:
— The attempt to save at reboot did not succeed.
— The SPE disk that is rebooted is not the same disk to which the logs were
last saved.
In such a case, the logs will not contain the most recent errors and alarms. To
determine if the restored logs are complete, look for indications that would have
preceded the reboot.
