ALR0611E The Port Send Bandwidth Percentage of port port name in device device name was measured to be measured value%, which violated the critical-idle boundary value of boundary value%.
Explanation
Port Send Bandwidth Percentage measures the approximate bandwidth utilization percentage of the ports in monitored storage systems and switches, based on their current negotiated speed. This value represents the ratio of the current send data rate to the maximum send data rate achievable at the negotiated speed. Since fibre channel protocols are full-duplex, the sum of the send and receive bandwidth percentages can theoretically reach a maximum of 200%. 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 Port Send Bandwidth Percentage value that is less than or equal to the critical-idle boundary that was defined for the related threshold.
Action
The threshold violation might indicate an unexpected drop in the workload for this port. This can happen if the application(s) using the port stopped working properly.
This type of threshold boundary should only be defined if the workload for the ports in a storage system or switch are guaranteed to always remain at a certain minimum level. Otherwise IBM Spectrum Control might recognize many violations, even though there is really no underlying problem with the applications. In these situations, consider decreasing the boundary value in the threshold definition, or disabling the boundary check by leaving the boundary value blank.
