Unable to See and add new ESXi hosts in Nexus 1000v

After the VMWare upgrade from 5.x to 6.x and Nexus 1000v upgrade from 4.2 to 5.2 you are unable to add new hosts into the Nexus 1000v distributed switch, although the older hosts are seed added to the N1Kv distributed switch and running fine without any issues.

This happens because Nexus 1000v has no knowledge of new versions of vCenter Server in its postgress database.

You have to manually add the new version in the vCenter database to support the new Version.

First you need to log in the the VCDB on command line, and for that you need to find the userID and password.

To get the userID and password, open C:\ProgramData\VMware\vCenterServer\cfg\vmware-vpx\vcdb.properties

vcdb.properties file contents should look like this

driver = org.postgresql.Driverdbtype = PostgreSQLurl = jdbc:postgresql://localhost:5432/VCDB
username = vcpassword = {FNr2Aad>ws8Xo<Qpassword.encrypted = false

Grab the username and password (default userID happend to be "vc" and the password

To add the new version

Go to this Path on DOS Prompot
C:\Program Files\VMware\vCenter Server\vPostgres\bin\

Run Command
C:\Program Files\VMware\vCenter Server\vPostgres\bin>psql -U vc VCDB
Enter password as found above in the the file at C:\ProgramData\VMware\vCenterServer\cfg\vmware-vpx\vcdb.properties
Password for user vc:

Show database

Insert the new version into the database with follwoing command

Here 42 is the device ID and can be seen in the first column of the output of command

Again show the database bases, it should now list the support for vCenter 6.0+ version.

Show database

You should see the New vCenter version has been added to the database.

Exit the Database command prompt by typing \q

Restart the vCenter Server and add the hosts to Nexus 1000v normally.
