Description
This guide will help you identify the proper solution based on your networking issue.
For example:
- Operation timed out
- No route to host
- couldn't connect errors
These indicate that either ONTAP is using an invalid route or it could not obtain a route.
- Review the LIF and route configuration to ensure ONTAP is using the management interface. (node mgmt and cluster mgmt LIF)
For a smoother experience, run the following command to gather your Nodes configuration
Verify your current configuration

This can usually be ignored. If you are using IPv6 for your Admin SVM, then this is relevant .. otherwise it is just a symptom of a routing issue, either IP config, routing or hostname resolution. |
