VMware's KB's on this are not helping, I cannot find what I need for my exact situation: I am locked out of vSphere, but can login locally to the ESXi host at the console (physically, standing at the KVM) EDIT: I just found out this is called the DCUI. I have enabled SSH and the ESXi shell, but cannot login to either one of them either. What are my options here? I believe what happened is my predecessor setup vCSA 6 on this host (and set vCenter to manage the host itself, thus locking it), but I am not sure since I cannot get into either. Thank you.
