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 a variety of locations in the chassis and in any
attached systems.
•
Fan Sensor — Monitors fans in various locations in the chassis and in any
attached systems.
•
Voltage Sensor — Monitors voltages across critical components in various
chassis locations and in any attached systems.
•
Current Sensor — Monitors the current (or amperage) output from the
power supply (or supplies) in the chassis and in any attached systems.
•
Chassis Intrusion Sensor — Monitors intrusion into the chassis and any
attached systems.
Table 1-1. 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 significant, 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 significant 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.
