I have an ESX host that shows disconnected from Vcenter. I can ping it from the Vcenter server.

When I right-click on it and try to connect it will give me a message :
reconnecting a host will override any resource management changes that were made directly on the host.to keep these changes, remove host from inventory and add it again.

if I select Remove, I get another message that says "removing a host will remove all its associated virtual machines….."

I am not sure which of the options I should select to make the ESX host shows up in Vcenter as online…

Any help will be very much appreciated.

Thanks

When you Click Disconnect/Reconnect, does it reconnect? There should be no reason, to remove from Inventory?

These are just warnings, no downtime or changes will occur to any of the VMs.

So just remove from the Inventory, and Add to Inventory.

There is no option to Disconnect  when I right click on the ESXhost, it is already disconnected, but I see the option "Connect". I am just not sure about the message I got when I selected connect and also when I selected Remove.

If I remove it then Add it , then will it keep any previous configuration regarding clustering or resource pool,etc…

If you click Connect does it connect.....even if you click any prompts, okay, yes etc

yes, cluster information is stored in the vCenter database.

Weird…
I restart Wmware Vcenter services and now that defunct ESX host is  showing connected..
the only ESX host that was showing disconnected the other ESX hosts were all showing good..
so it sounds like Vcenter was not communicating well with only that single ESX host…

This can happen, check the logs regularly, sometimes the Agent on the ESXi host can enter a hung state.

Usually

1. Restarting Network Management Agents on ESXi Host
2. Restarting vCenter Server Service

can resume comminication, or a Host Server restart.

It's not uncommon, for a host to become disconnected.

Make sure you have Alerts Enabled!
