Course Overview
In this course, you increase your proficiency as a NetApp® ONTAP® software engineer by learning how to troubleshoot ONTAP environments. Specifically, you learn how to troubleshoot the management component, scale-out networking, NAS protocols (NFS), and SAN protocols. From lectures, demonstrations, and active exercises, you learn how to isolate issues, verify configurations, view logs, view trace messages, and use event management system (EMS) messages for troubleshooting.
Who should attend
NetApp Technical Support engineers, Support Services Certified partner engineers, and Professional Services engineers
