ALR0551E The Link Failure Rate of port port name in device device name was measured to be measured value cnt/s, which violated the defined critical-idle boundary value of boundary value cnt/s.
Explanation
Link Failure Rate measures the average number of link errors that were received per second for ports. A threshold was defined on this metric, which causes the measured value to be compared to the defined boundaries for each set of performance statistics collected from the storage system or switch.
This message indicates that a threshold boundary violation occurred. In this case, the specified port in the storage system or switch has a Link Failure Rate that is less than or equal to the critical-idle boundary that was defined for the related threshold.
Action
It makes little sense to enable an idle boundary for the port error thresholds, because a zero or low error rate is the ideal and expected situation. It is recommended to disable the idle boundary checking by leaving the idle boundary values blank in the related threshold definition.
