Table 2. Understanding Event Messages
Icon Alert Severity Component Status
OK /Normal /
Informational
An event that describes the successful operation of a unit. The
alert is provided for informational purposes and does not
indicate an error condition. For example, the alert may indicate
the normal start or stop of an operation, such as power supply
or a sensor reading returning to normal.
Warning / Non-critical An event that is not necessarily signicant, but may indicate a
possible future problem. For example, a Warning/Non-critical
alert may indicate that a component (such as a temperature
probe in an enclosure) has crossed a warning threshold.
Critical / Failure / Error A signicant event that indicates actual or imminent loss of
data or loss of function. For example, crossing a failure
threshold or a hardware failure such as an array disk.
Server Administrator generates events based on status changes in the following sensors:
• Temperature Sensor — Helps protect critical components by alerting the systems management console when temperatures become
too high inside a chassis; also monitors the temperature in a variety of locations in the chassis and in attached system(s).
• Fan Sensor — Monitors fans in various locations in the chassis and in attached system(s).
• Voltage Sensor — Monitors voltages across critical components in various chassis locations and in attached system(s).
• Current Sensor — Monitors the current (or amperage) output from the power supply (or supplies) in the chassis and in attached
system(s).
• Chassis Intrusion Sensor — Monitors intrusion into the chassis and attached system(s).
• Redundancy Unit Sensor — Monitors redundant units (critical units such as fans, AC power cords, or power supplies) within the
chassis; also monitors the chassis and attached system(s). For example, redundancy allows a second or nth fan to keep the chassis
components at a safe temperature when another fan has failed. Redundancy is normal when the intended number of critical
components are operating. Redundancy is degraded when a component fails, but others are still operating. Redundancy is lost when
there is one less critical redundancy device than required.
• Power Supply Sensor — Monitors power supplies in the chassis and in attached system(s).
• Memory Prefailure Sensor — Monitors memory modules by counting the number of Error Correction Code (ECC) memory
corrections.
• Fan Enclosure Sensor — Monitors protective fan enclosures by detecting their removal from and insertion into the system, and by
measuring how long a fan enclosure is absent from the chassis. This sensor monitors the chassis and in attached system(s).
• AC Power Cord Sensor — Monitors the presence of AC power for an AC power cord.
• Hardware Log Sensor — Monitors the size of a hardware log.
• Processor Sensor — Monitors the processor status in the system.
• Pluggable Device Sensor — Monitors the addition, removal, or conguration errors for some pluggable devices, such as memory
cards.
• Battery Sensor — Monitors the status of one or more batteries in the system.
• SD Card Device Sensor — Monitors instrumented Secure Digital (SD) card devices in the system.
