Troubleshooting: Discovery Does Not Start

Symptom:

I select discovery profiles and click Run to run a discovery, but discovery fails to start, or the Run button is disabled.

Solution:

Possible reasons for a discovery failure or for a disabled Run button include the following:

The IP domain previously specified in the discovery profile has been deleted. Assign the discovery profile to an IP domain.
No Data Collector has been installed for the IP domain that is specified in the selected discovery profile.
Note: For information about installing Data Collector hosts, see the Data Aggregator Installation Guide.
One or more Data Collector hosts are installed for the IP domain that is specified in the selected discovery profile. However, all of the Data Collector hosts that are installed for the IP domain are stopped. Start the Data Collector hosts.
The tenant is deactivated. Activate the tenant.
