ALR0660E The Credit Recovery Link Reset Rate of port port name in device device name was measured to be measured value cnt/s, which violated the defined critical-stress boundary value of boundary value cnt/s.

Explanation

Credit Recovery Link Reset Rate estimates the rate at which link resets were performed in order to recover buffer credits. Link resets may be performed for other reasons, but this metric estimates the rate for only buffer credit recovery by ignoring any resets that may have been caused by loss of synchronization or loss of signal conditions. 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 switch.

This message indicates that a threshold boundary violation occurred. In this case, the specified port in the storage system or switch has a Credit Recovery Link Reset Rate value that is greater than or equal to the critical-stress boundary that was defined for the related threshold.

Action

The threshold violation might indicate that a hardware or configuration problem exists either for this port or for the connected fabric. Isolated errors can be ignored in most cases, but if the rate remains consistently high over time, this may be a cause for concern. Follow the trouble-shooting guidelines for the switch, and for the connected entity (storage system, switch, or server HBA).

Because isolated temporary errors can be ignored in most cases, consider enabling the alert suppression option "Suppress alerts unless the triggering condition has been violated continuously for a specified length of time" for this threshold. This can greatly reduce the number of unnecessary alerts.
