Severity

NOTICE

Description

This message occurs when ONTAP® detects that the average SCSI I/O command latency on the target port of the array exceeds the set threshold. This message indicates a degradation of I/O throughput for the target port of the array.

Corrective Action

Reduce the I/O load on the device, increase the number of array target ports available for I/O, and/or alleviate the cause for the excessive latency on the device.

Syslog Message

Average latency of %dus on target port %s, has exceeded %dus

Parameters

avg_latency (INT): Current average latency of commands for the array target port in microseconds.
wwpn (STRING): World Wide Port Name of the array target port on which the excessive latency was detected.
threshold (INT): Threshold value for excessive average latency in microseconds.
