Hi,

When I run discovery for network devices, the device get classified but CI field is empty.Then I checked the discovery log, I could see network pattern is failed.

So i started debugging and found this error "relation and/or reference table cmdb serial_number is not a known ci type. check the discovery logs for more details."

If anyone faced this issue. Please share your inputs.

Thanks.
