ALR0623E The Invalid Transmission Word 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
Invalid Transmission Word Rate measures the average number of invalid transmission words that were detected by the port, per second. Transmission words are primitive elements used by the fibre channel protocol for transmission of data. A frame consists of between 10 and 537 transmission words. 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 an Invalid Transmission Word 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.
