ERROR

This message occurs when Data ONTAP® has lowered the number of I/O commands that are allowed to be active by at least 25 percent for an array's target port. This message indicates degradation of I/O throughput for the indicated array's target port and the cause should be corrected.

Analyze the EMS logs for EMS_fci_device_timeout, EMS_scsi_cmd_adapterResources or EMS_scsi_cmd_targetStatus indicating of "Busy" or "Queue Full" events associated to the array's target port and correct any hardware faults. Reduce the shared load on the device and/or reduce the maximum allowed I/O commands for the array's target port. For example, to reduce the maximum allowed I/O commands for an array's target port, the following command can be run: storage array port modify -name ARRAY_NAME_1 -wwnn 50014380025d1500 -wwpn 50014380025d1508 -max-queue-depth 256

Array target port of %s has had its dynamic target port queue depth lowered to %d which is 25%% or lower of its maximum allowed value of %d.

wwpn (STRING): World Wide Port Name of the array's target port which has its queue depth decreased by 25% or more.
current_qdepth (INT): Current number of allowed active I/O commands for the array's target port.
max_qdepth (INT): Maximum allowed value of the array's target port queue depth.
