To be able to link two vCenter Servers, ensure that you meet these requirements:
  • DNS is set up and configured.
  • Both vCenter Servers are either in the same domain, or in different domains with a two-way trust relationship set up.
  • Both vCenter Servers do not have their time settings more than 5 minutes apart (use NTP).
  • Both vCenter Servers have the correct licensing.
  • Ensure all vCenter Servers in a Linked Mode group are registered to the same vCenter Single Sign On server.
  • The installer is run by a domain user who is a local administrator on both the vCenter Server systems.

If your issue persists after meeting these requirements, check the jointool-0.log file located at C:\Documents and Settings\User\Local Settings\Temp\.

If the jointool-0.log file contains the error instance GUID for remote vCenter Server is same as the GUID for this vCenter Server and the databases for both vCenter Servers are on the same remote database server, ensure that you are not using the same SQL user account for both databases unless each ODBC connection specifies which vCenter Server database to use.
The Linked Mode installation verifies the vCenter Server's GUID from the database and each SQL user has a default database. When you use the same SQL user account for both databases, the installation attempts to read from the default database for both users, find them to be the same, and fails with the error.
To resolve this issue:
  1. Create a new SQL user.
  2. Assign DB_owner privileges on the correct database to this user.
  3. Change the ODBC connection on one of the vCenter Server machines andspecify the new SQL user.
  4. Reinstall vCenter Server on one of the vCenter Server machines and specify the new SQL user for the database.
