Redundancy Unit Traps

Redundancy means that a system chassis has more than one of certain critical

components. Fans and power supplies, for example, are so important for

preventing damage or disruption of a computer system that a chassis may

have extra fans or power supplies installed. Redundancy allows a second or

nth fan to keep the chassis components at a safe temperature when the

primary 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 the

number of components functioning falls below the redundancy threshold.

The number of devices required for full redundancy is provided as part of the

trap message when applicable for the redundancy unit and the platform. For

more details on redundancy computation, please refer to the respective

platform documentation.

TrapID Description Severity Cause

1304 Redundancy regained

Redundancy unit: <Redundancy

location in chassis>

chassis>

Previous redundancy state was:

<State>

Number of devices required for

full redundancy: <Number>

Information A redundancy sensor in the

specified system detected

that a lost redundancy

device has been reconnected

or replaced; full redundancy

is in effect. The redundancy

unit location, chassis

location, and previous

redundancy state are

provided.
