Redundancy Status |
Status can be Full, Degraded, or Lost.
If the number of fans in a system that is required for full redundancy
is three:
Redundancy status is Full when three fans are
working.
Redundancy status is Degraded when two fans are
working.
Redundancy status is Lost when one fan is
working.
Full redundancy is defined by system specification. Degraded
redundancy means that one or more of the extra fans is not working in
the normal range. Lost redundancy means that there are no backup fans
available to take over for the minimum number required, but at least
one fan is working.
Critical/Failure status would describe a system that
had no working fan, and redundancy is designed to make this sort of
system failure unlikely.

Number of devices required for full redundancy | Your system has a number of fans defined for full redundancy. If the number of fans required for Full redundancy is three, redundancy is degraded when two fans are working, and lost when only one fan is working. |
Status | Displays whether the event type for the probe is Normal/OK, Warning/Noncritical, or Critical/Failure. |
Probe Name | Displays the alphanumeric text that uniquely identifies a fan probe; for example, CPU Fan. |
Reading | Displays a snapshot of the fan RPM actually measured by the probe at a given time. |
Minimum Warning Threshold | Displays the lowest acceptable fan RPM that is recommended for system operation. Values that fall below this RPM level result in warning events. |
Maximum Warning Threshold | Displays the highest acceptable fan RPM that is recommended for system operation. Values that exceed this fan RPM result in warning events. |
Minimum Failure Threshold | Displays the lowest acceptable fan RPM that is required for system operation. Values that fall below this fan RPM result in critical/failure events. |
Maximum Failure Threshold | Displays the highest acceptable fan RPM that is required for system operation. Values that exceed this fan RPM result in critical/failure events. |
