Verify That vCenter Server Can Communicate with the Local Database
If your database is located on the same machine on which vCenter Server is to be installed, and you have
changed the name of this machine, verify the conguration. Make sure that the vCenter Server DSN is
congured to communicate with the new name of the machine.
Changing the vCenter Server computer name impacts database communication if the database server is on
the same computer with vCenter Server. If you changed the machine name, you can verify that
communication remains intact.
If your database is remote, you can skip this procedure. The name change has no eect on communication
with remote databases.
After you rename the server, verify with your database administrator or the database vendor that all
components of the database are working.
Prerequisites
n
Make sure that the database server is running.
n
Make sure that the vCenter Server computer name is updated in the domain name service (DNS).
Procedure
1 Update the data source information, as needed.
2 Ping the computer name to test this connection.
For example, if the computer name is host-1.company.com, run the following command at the Windows
command prompt:
ping host-1.company.com
If you can ping the computer name, the name is updated in DNS.
vCenter Server communication is conrmed. You can continue to prepare other components of your
environment.
Verify Network Prerequisites Before Upgrading
Verify that your network is set up correctly and meets connectivity prerequisites for upgrading
vCenter Server.
For information on creating a PTR record, see the documentation for your vCenter Server host operating
system.
For information about conguring Active Directory, see the Microsoft Web site.
Domain users that are part of a Windows Administrators group with vCenter Server Administrator
permission cannot be used to authenticate vCenter Server during upgrade and do not have vCenter Server
permission after upgrade.
Procedure
1 Verify that the fully qualied domain name (FQDN) of the system where you will upgrade
vCenter Server is resolvable. To verify that the FQDN is resolvable, type
nslookup -nosearch -nodefname your_vCenter_Server_fqdn at a command-line prompt.
If the FQDN is resolvable, the nslookup command returns the IP and name of the domain controller
machine.
