After you upgrade to vCenter Server 5.0, you can join the system to a Linked Mode group. A Linked Mode group allows you to log in to any single instance of vCenter Server in the group and view and manage the inventories of all the vCenter Server systems in the group.

See Linked Mode Prerequisites for vCenter Server.

Note

Joining a version 5.0 vCenter Server to older versions of vCenter Server is not supported.

1

From the Start menu, select All Programs > VMware > vCenter Server Linked Mode Configuration.

2

Click Next.

3

Select Modify linked mode configuration and click Next.

4

Click Join vCenter Server instance to an existing linked mode group or another instance and click Next.

5

Type the server name and LDAP port number of any remote vCenter Server that is or will be a member of the group and click Next.

If you enter an IP address, the installer converts it to a fully qualified domain name.

6

If the vCenter Server installer detects a role conflict, select how to resolve the conflict.

A conflict results if the joining system and the Linked Mode group each contain a role with the same name but with different privileges.

Option

Description

Yes, let VMware vCenter Server resolve the conflicts for me

Click Next.

The role on the joining system is renamed to vcenter_namerole_name where vcenter_name is the name of the vCenter Server system that is joining the Linked Mode group and role_name is the name of the original role.

No, I'll resolve the conflicts myself

To resolve the conflicts manually:

a

Using the vSphere Client, log in to the vCenter Server system that is joining the Linked Mode group using an account with Administrator privileges.

b

Rename the conflicting role.

c

Close the vSphere Client session and return to the vCenter Server installer.

d

Click Back, and click Next.

The installation continues without conflicts.

7

Click Finish.

vCenter Server restarts. Depending on the size of your inventory, the change to Linked Mode might take from a few seconds to a few minutes to complete.

The vCenter Server instance is now part of a Linked Mode group. It might take several seconds for the global data (such as user roles) that are changed on one machine to be visible on the other machines. The delay is usually 15 seconds or less. It might take a few minutes for a new vCenter Server instance to be recognized and published by the existing instances, because group members do not read the global data very often.

After you form a Linked Mode group, you can log in to any single instance of vCenter Server and view and manage the inventories of all the vCenter Servers in the group.

For information about Linked Mode groups, see the vCenter Server and Host Management documentation.
