While preparing a host for NSX, the host will fail to prepare with the error message: "26164: Transport Node cannot be created or updated because host is not attached to every VDS specified in Transport Node Profile."
VMware NSX
When preparing an ESXi host as an NSX Transport Node, all hosts must be connected to all distributed virtual switches (VDS) associated with the desired Transport Node Profile.
If the host is not associated with all distributed virtual switches NSX will not be able to prepare the host.
See Add a Transport Node Profile and Prepare ESXi Cluster Hosts as Transport Nodes by Using TNP for further details.
Via vCenter GUI, ensure the ESXi host is assigned to all necessary distributed virtual switches (VDS) with the necessary uplinks.
