ONTAP Error Response Codes

Error Code Description

124519405

The activity tracking report for SVM svm.name returned zero records. Check whether the volumes belonging to the SVM have read/write traffic. Refer to the REST API documentation for more information on why there might be no records.

124519406

Failed to get the activity tracking report for SVM svm.name. Reason:.

124519407

SVM wildcard queries are not supported for activity tracking reports.

124519408

Activity tracking is not supported on SVM svm.name, because it is configured as a destination for SVM DR.

124519409

Activity tracking is not supported on SVM svm.name, because it is configured as a destination of a MetroCluster SVM relationship and the SVM admin state is stopped.
