Reconnect or Remove ESX host from Vcenter

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

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…

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…
