connectivity, OMNI UI launch, SmartFabric instance configurations, and OMNI automation.
Troubleshooting tools
Use the following tools when you run into any issues or during troubleshooting.
Logs and support data for troubleshooting
You can generate a support bundle with error and debug logs using OMNI. These logs can help you to identify, diagnose, and
debug problems.
Dell Technologies recommends downloading the support bundle from the OMNI Appliance Management UI. By default, the
log-level in OMNI appliance is set to ERROR. You can toggle the appliance log setting between ERROR to DEBUG. Change the
log-level appropriately for each service and download the support bundle, see OMNI Appliance Management UI.
NOTE:
Dell Technologies recommends setting the log level to DEBUG when you are experiencing any appliance issue and
want to generate a support bundle.
If you cannot access the UI, use the OMNI console to download the support bundle at /tmp/support-bundle.tar.gz
on the OMNI VM. You can also change the log-level. When you change the log level from ERROR to DEBUG from OMNI
VM console, the change applies to only the services omni_api and omni_services. For more information about OMNI
management menu, see OMNI console menu.
Verify OMNI VM connectivity
After setting up OMNI, verify the IP address, DNS settings, and connection status from the OMNI VM console:
1. When OMNI is deployed in one of the VxRail nodes in the cluster, ensure that you have configured IPv6 information for
VxRail Mgmt network (ens192) and custom route as fde1:53ba:e9a0:cccc::/64. Disable IPv4 configuration for ens192
interface.
2. When OMNI is deployed on an ESXi server and registered with an external vCenter, ensure that you have set IPv4
configuration with subnet mask and gateway information for the vCenter server network (ens160). Set the IPv6
configuration for the interface to Ignore.
3. Check the interface connection status through the OMNI console.
To check the interface configurations through the OMNI console:
