DNAC Issue --- Can not re-discover device

[MikeyD1]

Hi Guys

I have a problem where a few devices that was listed in my inventory was deleted and I'm not able to rediscover it. I have tried to add it but I get the following message. "NCIM11003: Device with IP address 192.168.11.139 already exists in inventory" However when I look they are not listed.

Is there a way to clear it out completely so it can be re-discover as a new hosts?  This is a Non-Fabric environment. 

Thanks for your help.

what version of DNAC, you should also remove from inventory SR NO to rediscover again.

Can you also confirm if the devices were onboarded with PnP? I would check the PnP portal in the UI to ensure they are not listed there. I would also filter the inventory page in the UI by serial number and then management IP address to ensure the devices are not in inventory. Make sure to do this on the Global location and not at a site level.
