Course Overview
The Storage System Recovery and Troubleshooting class is focused on advanced and in-depth topics regarding offline storage systems. Where previous classes in the new hire OnRamp program covered ONTAP diagnostic commands; this class covers what the commands are doing in the background. This deeper understanding will enable TSEs to form action plans based on feedback from the offline system, rather than following a pre-written template. The class is intended to provide to students the knowledge to resolve the majority of unavailable systems without escalation.
