The GUI still seems to be running very slow, but the host reconnected to vCenter and I am able to login with root using the vSphere/web console once again. Maybe not? At this time, it still looks like Restart Management Agents is running in the KVM GUI. But I would assume that Restart Management Agents and services.sh restart would do the same thing. This method would always result in hanging on certain services, most notable the lsass service which is an Active Directory service which again points to the unintentional removal of the DNS entry for this host as the likely culprit that started all of this. The odd thing is I had spent a large portion of the day in the ESXi host Shell trying to restart all services using the services.sh restart command. This is located under F2-> Troubleshooting Mode Options-> Restart Management Agents.
I'd say this is PFM cause I'm not exactly sure what fixed it, but it started working after I ran the Restart Management Agents option from the ESXi KVM GUI. However, the KVM access runs extremely slow and I was also wondering if full System Event Logs (SEL) might be attributing to any of this and/or how to clear the event logs.Īfter troubleshooting for most of the day my ESXi host reconnected with the vCenter server. Everything appears to be configured fine in the Shell. How can I reconnect the host to vCenter given the information provided above? How can I regain login access to the host with the root login using vSphere? It should also be noted that I can login to the host directly via KVM and access the Shell. Currently all the VMs on the host are up, accessible, and running fine, but it is disconnected from vCenter. Also I'm not sure if restarting the host will even correct this issue. I'm trying to avoid restarting the ESXi host for two reasons a) my user's Domain Controller and Horizon View server are located on this host and restarting would cause interruption and b) because I cannot login to the host console, I'm not sure if I'll be able to restart the DC and View VMs after the host comes back up. It stays here for upwards of 20-30 minutes until it finally times out. At this point the Reconnect host task runs but does not progress beyond 0%. I have also selected the host in vCenter and clicked Connect (right-click -> Connection -> Connect). I've since re-added the host to the DNS server. After a bit of poking around, I noted the host was deleted from my DNS server. I also cannot login to the host using the vSphere client or web client using the root login. The event log shows Error Cannot synchronize host. I recently noted an ESXi host in my vCenter environment had a warning (not responding). My environment is ESXi 6.0 and vCenter 6.0.
