Alarm Information

Alarm Information

This topic describes alarm information.

When a fault occurs, the system generates logs and an alarm based on the faulty module. If the universal server manager (USM) is configured, the alarm is reported to the USM over the Simple Network Management Protocol (SNMP). The sensors on the device monitor the operating environment and generate alarms if the environmental conditions do not meet device operating requirements.

Event Alarms and Fault Alarms

Based on the impacts on the system, alarms are classified into the following types:

  • Event alarm

    Event alarms record the events that occur during normal system operating. Event alarms do not affect system operating.

  • Fault alarm

    Fault alarms are generated for faults that affect normal system operating.

NOTE:

This document describes fault alarms only.

Viewing Alarms

You can use the following methods to view alarms:

  • Use a terminal to log in to the iBMC command-line interface (CLI), and run the ipmcget -d healthevents command to view all alarms.

  • Use the network management software.

  • Use the iBMC web user interface (WebUI for short).

NOTE:
  • For sensors with alarm thresholds, log in to the iBMC CLI, and run the ipmcget -t sensor -d list command to view all threshold information.
  • For details about commands for the iBMC CLI, see the HUAWEI RACK ServeriBMC User Guide.

Alarm Severity

Alarms are classified into the following types by severity:

  • Minor

    Minor alarms are generated for the faults that do not have major impacts on the system; however, you need to take measures immediately before the faults get worse.

  • Major

    Major alarms are generated for the faults that may affect normal system operating or interrupt services.

  • Critical

    Critical alarms are generated for the faults that may power off the server and even interrupt services. You need to take measures immediately to rectify the faults.

Alarms of the server system contain the alarms generated for all components in the system. You can identify a fault by using the alarm information.
