Orphaned, disconnected or inaccessible?

I was asked the other day by one of my colleagues to explain what the difference was between each of these VM states so I figured I’d write a quick overview of each.

Orphaned VM

In a nutshell its a VM that vCenter still has a record of within the database, yet it either doesnt actually exist anymore, or isn’t on the host where vCenter expected to find it.

So how did it get into this mess? Well, quite simply really. Imagine you’re managing a two host cluster within vCenter and someone decides to administer one of the individual hosts directly through the vSphere client. They then proceed to remove one of the virtual machines from the inventory. As a result of this, the ESX host itself drops its record of the VM ever being there, but the vCenter DB still has record of its existence. As such vCenter marks this VM as “Orphaned”. To rectify this, either re-add the VM back to the standalone guest or remove the “Orphaned” entry from the inventory and re-add it. (note, if you do not remove the orpahned entry from vCenter server, you will not be able to re-add it as the same VM name).


This is usually when a datastore or its associated folder/files on the datastore have gone walkabouts and the host can no longer see the VMX file it used to talk to in order to maintain visibility within the vCenter server. This can sometimes happen if someone decides to rename the folder the VM resides in, without removing it from the inventory, renaming the folder and then re-adding it.

To resolve the inaccessible message, either relocate where the underlying VM has gone or remove it from the inventory completely.


This is usually as a result of the host that last managed the VM losing communication with the vCenter server. Any VMs that were running at the time of the break in communication (or indeed a manual right click on the host and clicking disconnect), will render the VMs under its control as disconnected.

To resolve the disconnected state, Connect the ESX host back into the cluster.
