Products

• VMware NSX

Issue/Introduction

• When you move a new ESXi host into the cluster, NSX install fails on the transport node with the validation errors as shown below:

       Validation Errors : 26164: Transport Node cannot be created or updated because host is not attached to every VDS specified in Transport Node Profile

 

Environment

VMware NSX 4.2

Cause

When preparing an ESXi host as an NSX Transport Node, all hosts must be connected to all the 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.

Resolution

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 new host is not associated with all distributed virtual switches NSX will not be able to prepare the host.
