When it comes time to remove your Cisco Nexus 1000V, whether in production or lab environment, one of the most common mistakes is to delete VSM without disconnecting the VSM from the vCenter. If that is what you did, you will soon discover that your N1KV still sticks around under the Networking and vCenter does not allow you to remove it. Although, there is a way to fix this but it is rather a painful process involving re-creating a VSM and force it to use the old extension key so you can register and unregister properly. Needless to say, you would be better off doing it right the first time. In this article, we walk you through step-by-step to completely remove both VSM and/or VEM in VMware. You will see that the process is, somewhat, a reverse of the installation.
