ESXi hosts intermittently disconnecting and reconnecting

ESXi hosts intermittently disconnecting and reconnecting

Issue: If you have recently rebuilt your VCenter server or are migrating to another VCenter server and are using distributed virtual switches you may encounter an issue with your ESXi hosts disconnecting and reconnecting immediately at a regular interval.

Cause: The distributed switch information store on the ESXi host does not match the information in VCenter and cannot link the two objects.

Resolution: Evacuate all VMs from the first ESXi host, put the ESXi host in maintenance mode, disconnect the host from VCenter (make sure you know the root password), remove the host from VCenter inventory, right click on the cluster and select add host and connect to the host in question, go to the virtual distributed switch and readd the host to the distributed switch, remove the host from maintenance mode, verify status messages and the configuration, migrate the VMs back to the ESXi host.
