Applies only to NetBackup Enterprise Server.
An Enterprise Media Manager domain includes all of the servers in the Enterprise Media Manager database and the devices, media, and storage they manage. The Enterprise Media Manager can manage more than one NetBackup master server. That is, multiple NetBackup master server domains can share one Enterprise Media Manager domain.
The following are the rules for an EMM domain:
The Enterprise Media Manager must be installed on a system that hosts a NetBackup master or media server. Symantec recommends that you install the EMM on the same system as a NetBackup master server.
Host names must be consistent throughout an EMM domain. Do not use a fully qualified name and an unqualified name to refer to the same host. Do not use a physical name and a virtual host name to refer to the same host.
All hosts in the same NetBackup domain must use the same EMM server.
Drive names must be unique within an EMM domain and should be descriptive.
