What 6.4 version are you using? 6.7 U1 is only compatible from 6.4.2: VMware Product Interoperability Matrices

is it a day 1 issue ?

what is the status of NSX manager and VC connectivity ?

what is the version of Vcenter ?

What is the error you are seeing under installation tab ?

As per NSX 6.4.4 release note:

Minimum Supported: 6.7

Recommended: 6.7 Update 1

When a host is deleted from the inventory without performing NSX Host unprep, entries related to this host are not cleaned up from the fabric table.

This causes the above symptom.

No hosts have been deleted.

We also received this issue when removing several hosts and clusters through the SDDC manager (we're running VCF 3.7.1).

Edit/update: Unfortunately we had to create an SR to resolve this issue. It was quickly fixed, they confirmed this is not something that can be done without GSS (it involves editing database entries).

Hi,

We have the same issue but we did remove our hosts and unfortunately they have been reused somewhere else, is there a way to clear the fabric table?
