Have you ever
faced a preparation error while configuring VXLAN ???
Regardless if
it was part of a bad preparation, a partially installation or an old
configuration remaining on the hosts, you might end up not being able to
configure VXLAN and will be presented with the error:
Cluster domain-cXX already has been configured with a
mapping.
The issue is
that a previous attempt was made and the configuration details was kept on vCNS Manager. To proceed you will need to clean that up.
I recommend you
follow this fix with a VMware support representative, in any case, here’s how
to fix it.
- Login to a server, which has cURL, installed (FYI: vCloud Director has
cURL installed on the cells);
- run the
following command;
curl
-i -k -H "Content-type: application/xml" -u admin:”password” -X
DELETE https://"vCNS”/api/2.0/vdn/map/cluster/”domain-cXX”/switches/dvs
replace
password with the password of your vCNS Manager
replace vCNS with the hostname of your vCNS Manager
replace
domain-CXX with the domain provided on the error message.
- Run the
preparation again.
This time it
will succeed.
