Transport node profile Fails to Prepare Transport Nodes Due to Stale Objects

Problem

Transport node profile (TNP) fails to prepare transport nodes due to stale objects in TNP.

Cause

NSX displays the following error when TNP fails to prepare hosts into transport nodes: The requested object <uuid> could not be found. Object identifiers are case sensitive. Please make the appropriate changes and reapply the configuration.

This issue can occur if any configuration specified in the TNP does not exist in NSX Manager or VMware vCenter.

Solution

1. Search the UUID in NSX Manager to find out the object being referred to in the error.
2. Edit the Transport Node Profile to remove the referenced stale object (could be TNP itself, IP Pool, Profile etc) and then retrigger host configuration.
