ONTAP Troubleshooting

In this Partner-only 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 SMB), and SAN protocols (iSCSI). From lectures, demonstrations, and active exercises, you learn how to isolate issues, verify configurations, view logs, view trace messages, and use event management system messages for troubleshooting.

Prerequisites

• A working knowledge of ONTAP software and NAS and SAN protocols
• ONTAP 9.6 Cluster Administration (ONTAP9ADM)

Target Audience

This is a Partner Only Course so expected audience to be NetApp Technical Support engineers, Support Services Certified partner engineers, and Professional Services engineers
